Exact Volume Pastettes (Pasteur or plastic pipettes)

The twin bulbs of the Dual Bulb Pastette control the volume of liquid dispensed for exact liquid transfers.
Frogs have simple vocal cords consisting of slits in the bottom of the mouth, which open into vocal pouches. When air passes through a sound is produced and inflating or deflating the pouches controls the volume. The twin bulbs of the Dual Bulb Pastette control the volume of liquid dispensed for exact liquid transfers.

Dual-Bulb Pastettes are designed to dispense an exact volume of liquid with foolproof simplicity.

The dual bulb pipettes, sometimes called exact volume pipettes, were originally designed for home pregnancy testing kits, where a measured sample needed to be added to the test by an individual with no previous experience of exact volume delivery.

They have since been adopted for a multitude of testing and reagent addition applications in all branches of industry.

A quick and easy alternative to pipettes and tips they are particularly useful in self-test and Point of Care (POC) diagnostic kits where users may not have experience of exact volume pipetting.

Simply squeeze the upper bulb to fill, and squeeze again to dispense the exact volume. These pipettes are available unsterilised in volumes from 20-250µl.
