PIPETTE BULBS MADE OF RUBBER GRAY VOLUME 2ML

Product details

Pipette bulbs made of rubber gray, Volume 2 ml

The rubber pipette suction ball sucks the required amount of approx. 10% into the pipette at normal pressure on the ball after letting go. When the pipette is closed, the liquid is pumped back to the desired mark.
This simplifies repeated pipetting and makes it possible to perform it in a minimum of time.
Green, grey and yellow balls use thumb and index finger.
With blue and red balls you put your thumb on the ball, index and middle finger on both sides of the neck and press with your thumb.
