functions two little constant bands on the higher end, making sure precise dispensing of the final drop of liquid.
Application: beneficial in situations exactly where vacuum aid enhances the precision of liquid measurements.
A measuring pipette with no bulb, featuring calibrations together its physique for fewer precise apps.
