3m pipette manualIn air displacement pipettes, a certain volume of air remains between the piston and the liquid. In positive displacement pipettes, the piston is in direct contact with the liquid. This creates a partial vacuum and the specified volume of liquid is aspiratedThe figure below shows the change in volume when the liquid has a different temperature than the pipette and air. If the temperature of the liquid, pipette and air is the same, the accuracy is not significantly affected. The density varies according to theThe air pressureThe boiling point of some liquids can also change to quite close to room temperature, increasing the evaporation loss dramatically. The micro-syringe tips used in positive displacement pipettes are disposable. This helps to avoid sample-to-sample cross-contamination (also known as sample carry-over), and contamination due to the aerosol effect. This causesThey should not be cleaned for reuse as theirLiquid mightPipette stands are ideal for this purpose. If used daily, a three-month interval isRemove the tip from the vessel,This volume is equal to the set volume.Some liquid will remain in the tip, and thisCan only be used with electronic and repeator pipettes. Hold the button in this position. Some liquid will remainThis action will fillRepeat thisCarbon filter tips prevent vapors from going into the Pipette. Reverse pipetting should be used if high accuracy is needed. Wipe the tip against the edge of the vessel to remove excess liquid outside the tip before dispensing. Reverse pipetting should be used if high accuracy is needed. Wipe the tip against the edge of the vessel to remove excess liquid outside the tip before dispensing. Filling must be done very slowly to prevent air bubbles. Wipe the tip against the edge of the vessel to remove excess liquid outside the tip before dispensing. The use of a positive displacement pipette and tip is also useful for pipetting glycerol.http://www.ethio3f.com/ehpea/userfiles/3ware-9500s-user-manual.xml

In any case pipetting will not be accurate; some liquid will stay inside the tip. Aspiration and dispensing should be done slowly. The use of a positive displacement pipette and tip is also advisable for pipetting Tween 20. Pre-wetting of the tip before aspiration increases accuracy. Do the pipetting quite rapidly to minimize vapor formation. If you use air displacement pipettes, aspirate and dispense the liquid a few times keeping the tip in the liquid. By doing so, the air inside the pipette will be saturated with vapor of the volatile compound. 2.) Pipette rapidly to avoid evaporation when using air displacement pipettes. 3.) It is recommended to use positive displacement pipettes for highly volatile compounds, since the built-in piston tip is in direct contact with the liquid. Prevention: Prevention: Prevention: The Pipette and the Tip form a System. The best Pipetting results are naturally achieved by those manufactured together to ensure complete compatibility between Pipettors and Pipettor Tip. Many of the cheap tips may have flashes, protrusions, and scratches, air bubbles, be bent or contain impurities. All these influence Pipetting results. For example, if the tip is not straight this alone may result in a 10 error in Pipetting accuracy (ISO 8655-2). Moreover, if the tip orifice is not accurately centered, the dispensing of the liquid might be affected significantly. If premium grade pure polypropylene is not used or the mold and processing are not up to the highest standards, part of the liquid stays inside the tip as a droplet, which causes an error in the Pipetting result. Adjustment means altering the pipetteDuring factory calibration, performance is checked with different weighings at both the maximum volumes of the range and at the minimum or 10 of the maximum volume, whichever is higher. When you purchase a Pipette, you should choose one that is designed to permit recalibration and adjustment for different temperatures and various viscous liquids.http://www.regionoverseas.com.np/userfiles/3ware-9550sxu-8lp-manual.xml Very often error limits are takenHowever, if the laboratory work requires the highest accuracy, the manufacturer?s limits should be used. Basically every user should define their own limits, according to the application used and the ambient conditions. The test water isRelative humidity is recommended to be above 45. Especially with volumes under 50 vl, the air humidity should be as high as possible to reduce the evaporation loss effect. If used daily, a three-month interval isCustomer will be advised if the damage is Repairable and what additional cost will be charged. Customer will issue a new Work Order to cover the cost of Repair.Customer will have opportunity to locate any missing quantities, or Work Order will need to be revised and revision signed by Customer.If this is a New Customer, a Customer information file will be started. Ten tests performed at each point. Pipette is again visually checked for proper functionality. If Pipette fails, appropriate Calibration adjustments are performed. After corrections, each instrument will be Calibrated at the lowest and highest range points with 10 tests at each test point.Appropriate technicians sign reports. If the calculated results are within the limits given in the Instructions-for-use booklet, the pipette calibration is correct. If not, the pipette has to be adjusted with the lower volume and checked again. Use in saturated air. Change technique. Change technique. Pre-wet tip. Immerse 2-3mm. Keep vertical. Change technique. Pipette liquids at room temp. To determine mass loss, dispense water into the weighing vessel, note the reading and begin timing with aTypically, the pipetting time might be 5 seconds and the mass loss up to 2 mg. If an evaporation trap or lid on the vessel is used, an evaporation correction is unnecessary. See the conversion Table 1 on page 15. It is expressed as standardIn addition to the features of the pipette,For multichannel pipettes, these limits are doubled.http://www.drupalitalia.org/node/67358 With variable volume pipettes, the nominal volume is the maximum volume. The absolute vl limit of the nominal volume applies to every selected volume throughout the volume range. If the nominal volume of the pipette is between those in the table, the relative error limit F of the nearest volume is used. If the nominal volume is exactly between the two volumes in Table 2, the relative error limit F of the lower volume is used. A number of factors canImmediately after autoclaving,It is also important to note that certain parts of a pipette - for instance the piston and the handle cannot be autoclaved without altering accuracy and precision Both types of pipettes have a piston that moves in a cylinder, or capillary. In air displacement pipettes, a specified volume of air remains between the piston and theThis keeps air from entering the tip, preventing contamination effectively. AirAn alternative to this is to use a positive displacementBy doing so, the air inside the pipette will be saturatedIt is recommend using positive displacementWith warm liquids, you will get a smaller mass with a certain volume, with cold liquids,San Diego, CA 92121.

Affordable so everyone in the lab can have a set. Units are designed with a unique air purging system that prevents loss of reagents and eliminates dripping or splashing of media. An exclusive reagent guard valve prohibits accidental discharge and eliminates the need for capping the discharge tube when the dispenser is not in use. The volume adjustment knob allows quick and easy setting, and locks the volume into place. Dispensers disassemble easily for cleaning. Automatic calibration eliminates readjustment. Basic dispensers have a PTFE system for broad general use. Choose a PTFE-lined dispenser for applications using hydrofluoric acid or a glass-lined dispenser for use with organic solvents. Additional adapters also available separately. Reservoir bottle not included. With the tight fit, the tip essentially wipes the interior of the syringe barrel free of sample. This feature is particularly useful with heterogeneous samples as it reduces the chance that a deposit will occur and cause the plunger to freeze. This series of syringes is ideal for dispensing volumes from 100?L up to 100mL. A variety of different terminations and needle options are available. Syringe Terminations. Removable needle syringes are a Hamilton-specific design. The design allows the needles to seat precisely at the zero graduation mark of the syringe. Users can select the needle gauge, length, and point style to optimize the syringe for custom applications. This termination also allows for a removable needle without increasing the dead volume of the syringe and is ideal when there is a risk of the needle clogging. Autoclavable when disassembled. Repeated autoclaving will shorten syringe life. Luer tip syringes feature needles that are removable and fit over a ground glass hub which is tapered in the shape of a male luer. This termination will accept most hypodermic needles but was designed specifically for use with Hamilton Kel-F needles. This termination also increases the dead volume in the syringe, which may not be appropriate for some applications. Luer tip cemented needle syringes are mid-volume syringes in which the needles are cemented into the glass syringe barrel at a point corresponding to the zero graduation mark. With this termination, dead volume is limited to the internal volume of the needle. Not autoclavable. Needle gauge is determined by the syringe volume and are not user-selectable. PTFE luer lock syringes have a PTFE, male Luer taper with nickelplated brass locking hub for use with Kel-F needles, metal hub needles, and universal connectors. The version with slots is used during the attachment to some instruments but does not effect the connection to needles. Autoclavable when disassembled, except on 25 mL and greater syringes. Needle Point Styles. Point style 2 is a sharp, beveled, curved, non-coring needle point recommended for septum penetration. Point style 3 is a blunt needle point for use with HPLC injection valves and for sample pipetting. Point style 5 is a conical needle with side port for penetration of septa, thin-gauged vinyls, and plastics without coring. Self-calibrating, microprocessor-based system reduces the possibility of human error and instrument contamination by controlling pipetting speed, calibration, and volume selection. Helps reduce the risk of repetitive strain injuries that are frequent with manual pipetting. Has over 1000 cycles when fully charged. How?

Basically, the pipettes must be safe for us to handle and accompanied by a signed Decontamination Declaration Form to confirm this, whether they needed decontaminating or not. This applies to both mail-in and on-site servicing. Please note that pipettes cannot be serviced if a signed Declaration is not received. Q. What makes of pipette can you service. We can service all brands and types of pipettes, although we may not be able to obtain spare parts for very old pipettes. We service single-channels, multi-channels, electronic pipettes, multi-steppers and positive displacement instruments, as well as bottle-top dispensers. Q. Can you break down my invoice by department, or grant code etc? Yes. We can invoice to your exact requirements. Q. Do you automatically replace seals and O rings? No. During the service we will thoroughly test these components for function and will replace them only if needed. This reduces costs to you. Q. Will you inform me of any expensive repairs needed? Yes. You can check the box on the Decontamination Declaration to be contacted before we proceed with any service if spare parts (excl.We will then phone or email you to discuss the best way to proceed. Q. What if my pipette is beyond repair. If, in our opinion, a pipette is beyond economical repair or spares are no longer available, we will return it to you with a label detailing the reason it is beyond repair. If required, we can arrange a Trade-In of your pipette for one of our own pipettes at a very attractive discount. Please note that a ?15 pound investigation charge may be applied for pipettes found to be beyond repair or uneconomical to repair if measurable time has been taken to establish this. Q. Is your measuring equipment traceable to recognised standards? Yes. All our balances are regularly calibrated and certified. Q. What accreditions do you have. We are an ISO 17025 UKAS accredited calibration laboratory (4296). We are also accredited to ISO 9001 Quality Management Systems and ISO 14001 for Environmental Management. We require the following information: We cannot work on any pipettes that are not accompanied by a form. Please ensure you complete ALL sections of the form and sign before sending. Standard Service: turn-around time is within 5 working days from receipt to dispatch, provided that we have all the information required. If, for any reason there is a delay, we will let you know beforehand and give you an estimated time of when your pipette will be returned. FastTrack Service: guaranteed turn-around time is within 48 hours from receipt to dispatch, provided we have all the information required. There is an extra charge for this service; 2020 pricing ?5 per single-channel and ?20 per multi-channel pipette. If for any reason there is a delay beyond 48hrs you will not be charged. Q. Will I be charged for return carriage? No. STARLAB does not pass postage charges on to its customers on the UK mainland. Other areas of the UK may be charged a small, nominal fee. We can calibrate any volume of pipette on site as long as the conditions allow us to do so. Small volume pipettes need a draft-free environment, no vibration and the location of the clinic cannot be in a thoroughfare. Each technician requires minimum 2m bench space with leg room and access to at least one 13A socket. The minimum number of pipettes required for an on-site clinic is on average, 20 to 40 per day, depending on the service level required and the condition of the pipettes. Please contact STARLAB to discuss your on-site requirements. Q. What details do I need to provide when booking an on-site clinic. We require the following information: Confirmations not received a month before the start of a proposed clinic may have to be rescheduled or cancelled. Q. What if I cannot confirm the exact number of pipettes. The minimum number of pipettes for an on-site clinic depends on the service level required, and although there is no maximum number of pipettes, we allocate a time frame and the appropriate number of technicians for a clinic, based on the information you give us. Should the number of pipettes that require servicing increase significantly, it may not be possible for us to service everything within the scheduled clinic duration. We will make every effort to accommodate extra numbers as quickly as possible.
