Pipettes

Commonly used handheld instruments in clinical laboratories and research settings, pipettes are used to measure small volumes of liquid and to transfer liquids or semi-solids in measured volumes. They are indispensable

in

experiments that involve acid or alkali reactions known as titration experiments.

Types of Pipette There are different models of this laboratory instrument. The basic functioning of each model is same, but choosing the right pipette is important if the required volume is to be measured accurately. Using the wrong model is often a source of common error in practical work which requires accurate volume measurement. In addition to accuracy, modern design focuses on reducing ergonomic risks. The following are the most common types of pipettes:

01

Transfer / Disposable This basic type of pipette is used for making rough measurements.

Quality models molded from polyethylene and feature an integral, one-piece design. In addition to avoiding the risk of breakage as with glass pipettes, they can be heat sealed for sample storage.

02

Fixed Volume Fixed volume micro and macro pipettes provide stable performance and consistent results for diagnostic or analytical tests by doing away

with

the

risk

of

flawed

volume

setting.

VistaLab

Technologies offers both these types - MLA Micro D-Tipper 2ÂľL features smooth two-stroke action (with overblow) enhancing repeatable results and performance with microvolume sample sizes and MLA Macro 1-5 mL is an adjustable volume model for pipetting between 1 and 5 mL, in 0.5mL increments and allows visual confirmation of the volume delivered.

03

Single Channel This device produces accurate measurement of results with the use of one disposable tip. A one way disposable nozzle does not allow liquid to get into the body of the device and there is no risk of contamination. The Single Channel Ovation Pipette by VistaLab Technologies provides dispensing increments of 10ÂľL and a volume range of 100-5000ul. With a low weight and relaxed grip design, this model makes repetitive pipetting effortless.

04

Multichannel The technique used in this model is similar to that of the single channel, except it uses more than one tip at a time. These instruments are suitable for demanding lab applications such as delivering a series of different volumes in any desired order or for mixing after delivery. The Ovation Electronic Multichannel model from VistaLab Technologies incorporates various features for ergonomic advantages and to boost pipetting efficiency. An audible ''click'' indicates that every tip is securely seated and sealed.

Pipette Tips In addition to choosing the right instrument for your application, it is important to find pipette tips that provide a perfect fit. If the liquid leaks, that means the tip does not fit properly. Leading manufacturers offer tips that feature different colors to match the pipette they are meant for.
