Micropipettors are standard laboratory equipment used to measure and transfer small volumes of liquids. Technological innovations have replaced the traditional designs of pipette with stunning micro pipette models that enable safe liquid handling in laboratories. Compared to glass pipettes, high precision micro-pipettes are now available that help avoid anomaly in measurements.
This liquid handling equipment generally used in laboratories is of two types – air displacement pipette and positive displacement pipette. While air displacement types are made for general use and used with normal aqueous solutions, the positive displacement ones are designed for specific purposes such as handling highly viscous and volatile liquids.
Despite the differences in shapes and sizes, the basic parts of a micropipette are – plunger button, tip ejector button, volume adjustment dials that can be dialed to the left or right to increase or decrease the volume, digital volume indicator, shaft and attachment point for a disposable tip.
Different pipette shapes are:
- P – 1000 that delivers 200 to 1000 microliters
- P- 200 that delivers 30 to 200 microliters
- P-20 that delivers 2 to 20 microliters
There are several companies that provide pipettes of different types. VistaLab Technologies and Stanbio are two leading manufacturers of this advanced liquid handling instrument. Their products include – MLA Micro D-Tipper 4µL Pipette, Seropette® Variable-Volume Pipettors, 5 – 50 uL and Seropette® Pipettor Tips, 100 – 1000 uL (Blue), 1,000 Pcs. These instruments are ergonomically designed to minimize hand fatigue, providing consistently high precision and accuracy,
Reputable lab equipment suppliers introduce innovative pipette models to meet the varied needs of laboratories. To ensure maximum accuracy, laboratories should consider operator consistency, and the pipettes should be calibrated at periodic intervals.
