WondaPipet Pipette - Working Principle
The suction and discharge of liquid are achieved through the telescopic movement of the spring. Under the push of the piston, some air is expelled, liquid is sucked in using atmospheric pressure, and then the piston pushes the air to expel the liquid. When using a pipette, the expansion and contraction characteristics of the spring can be used to control the speed and force of the pipette effectively.
WondaPipet Pipette - Product Features
Can disinfect the entire vessel at high temperature (121 ℃/20 minutes).
Can be disinfected with ultraviolet light.
The number setting processing is simple and easy to implement.
The simple locking knob design allows for one handed operation.
Ergonomic design ensures that long-term use will not cause fatigue.
The construction of * avoids the influence of hand temperature on accuracy.
8 different specifications can handle samples ranging from 0.1 μ L to 10mL.
Applying polytetrafluoroethylene to the airtight part of the pipette can maintain sealing and reproducibility for a long time.
Ceramic piston (200 μ L or more).
A pipette with a volume of 1000 μ L or more is equipped with a filter cartridge for the liquid collection head.
Easy to retract without touching the suction head.
Plastic return head component to avoid damaging the test tube.
