Product Information

A pipette (sometimes spelled as pipet) is a type of laboratory tool commonly used in chemistry and biology to transport a measured volume of liquid, often as a media dispenser. Pipettes come in several designs for various purposes with differing levels of accuracy and precision, from single piece glass pipettes to more complex adjustable or electronic pipettes. Many pipette types work by creating a partial vacuum above the liquid-holding chamber and selectively releasing this vacuum to draw up and dispense liquid. Measurement accuracy varies greatly depending on the instrument. Micropipette: These are used to measure very small volumes of liquid, typically in the range of microliters or even nanoliters. A graduated pipette commonly used in medical technology with serologic pipettes for volumetric analysis. Invented by Donald Dexter Van Slyke. [6] Ostwald–Folin pipette [ edit ] Integrated pipetting protocols – with pre-set or custom programs to minimize operator errors. Watch the video tutorials on our pipetting programs to see some examples.

When choosing instruments for life science processes, reliability and precision are the foundation of accurate diagnostics. Seamless Integration Straightforward calibration – with built-in gravimetric performance validation. Simply enter the dispensed versus target volume, and it will self-calibrate. Many electronic pipettes also offer calibration reminders. Microfluidic pipette [ edit ] A Microfluidic pipette, housed in a manifold holder. The colored solutions highlight the solutions loaded into the wells of the PDMS pipette. Pneumatic actuation is used to keep all tubing free of contamination.Preparing Solutions: In chemistry, solutions with specific concentrations are required, and pipettes are used to prepare these solutions. Volumetric pipettes are commonly used for preparing solutions of a specific volume and concentration. These pipettes have two small continuous bands located on the upper end of the pipette. These pipettes will dispense even the last drop of liquid into the receiving container. It may sound cliché but when it comes to best-practice pipette function in laboratory, reading the manual is key. Every pipette is different, and functions can vary between models, even if they fall into the same category. All laboratory personnel should have a good understanding of how to use the pipettes available in their workplace. As well as improving accuracy, efficiency and reliability, in-depth knowledge of pipette laboratory apparatus uses is an important part of workplace health and safety. The very first thing you should do is make sure that you choose the right pipette for your experiment. As explained above, an adjustable volume air displacement pipette is most accurate when pipetting at its maximum capacity, so you should always choose the smallest pipette capable of handling the required volumes. A pipette filler is a tool that is used to draw up liquid into a pipette without the need for a pipette bulb. It is a handheld device that is attached to the top of the pipette, and can be used to control the amount of liquid being transferred. Pipette Pump

Multichannel electronic pipettes combine the efficiency of multiple heads with the ergonomic benefits of automation. The use of both technologies can drastically boost efficiency when microplate filling. In many cases, the time needed to complete the task can be reduced to less than a minute. Cleaning the outside of the pipette should be part of your daily routine. Simply wipe it with a lint-free cloth lightly soaked with 70 % ethanol.

Always consult the operating manual of your pipette before cleaning it. It often contains detailed information about the chemical compatibility of your pipette with common cleaning agents, and tells you how to disassemble and reassemble it. Klingenberg, M (2005). "When a common problem meets an ingenious mind". EMBO Rep. 6 (9): 797–800. doi: 10.1038/sj.embor.7400520. PMC 1369176. PMID 16138087. Used in tissue and cell culture applications, serological pipettes are generally manufactured from glass or polystyrene. In laboratories where sterilisation is a priority, scientists will often use disposable pipettes made from durable plastic. Serological pipettes are also commonly used liquid dosages of more than 1mL. Repetitive strain injury is one of the most common risks encountered by laboratory scientists. Electronic pipettes minimise the risk of injury by automating the air displacement process. Equipped with an internal motor, electronic pipettes offer the same accuracy and precision as their hand-operated counterparts but without the physical strain. Electronic pipettes are particularly useful when multi dispensing, a process that involves dividing a reagent into different doses.
