In addition, the SP20 integrates a drive controller, which controls the operation of the motor by receiving instructions from the host computer to achieve complicated liquid aspirate and dispense.

Air Displacement Pipette SP28
This module includes a sensitive pneumatic liquid level detection(pLLD) that can detect the liquid level immediately. Ultra-high precision, flexible, intelligent control.

Air Displacement Pipettes Benefits
1
Liquid handling instruments include automated pipetting systems, typically used for copying, aliquoting, pooling, mixing, and serial diluting liquids.

2
Automated liquid handling systems are designed to speed up pipetting and dispensing liquid compared to manual pipetting.

3
At the same time, they significantly improve workflow accuracy for a variety of liquid types and volume ranges.

Air Displacement Principle.
Explain the Principle of Air Displacement and Positive Displacement PI
Air displacement pipetting, also known as blowout pipetting or reverse pipetting, is a technique used in laboratories to dispense liquids with high accuracy and precision. The principle behind air pipetting is that a positive air pressure is used to dispense a liquid from a pipette tip.

To perform air displacement pipetting, a pipette with a disposable tip is used. The tip is attached to the end of the pipette, and the liquid to be dispensed is drawn up into the tip using the pipette's plunger. Once the desired volume of liquid is in the tip, the pipette is held in a vertical position and the plunger is depressed slightly to create a positive air pressure in the pipette.

The positive air pressure forces the liquid out of the tip in a controlled manner, allowing the user to dispense precise volumes of liquid. The tip is then removed from the liquid, and any remaining liquid in the tip is expelled using the same positive air pressure.

Air displacement pipetting is particularly useful when dispensing viscous or foamy liquids that are difficult to dispense using traditional pipetting techniques. It is also useful when working with small volumes of liquid, as it allows for precise and accurate dispensing.

However, it is important to note that air displacement pipetting can create aerosols and droplets, which can pose a safety hazard when working with hazardous materials. Proper safety precautions, including the use of personal protective equipment and proper ventilation, should always be taken when performing air pipetting in the laboratory.

Air Displacement Pipettes FAQs

What is air displacement pipette used for?
Specific quantities of liquids are moved from one location to another using air displacement pipettes. These are mostly utilized in analytical and microbiological studies, cell biology, DNA analysis, PCR, etc, where small volumes are used. Both fixed capacity and variable volume pipettes are available.

How does an air displacement pipette work?
The air displacement pipette (ADP) performs air displacement through an internal adjustable ball screw. The drive is the coreless blushless DC motor with encode. The ADP picks up a disposable tip, the liquid is aspirated from liquid reservoir to tips then to another reservoir.
