VOLAC Glass Pasteur Pipettes
All VOLAC Glass Pasteur Pipettes are precision made from carefully selected tubing (soda lime glass, borosilicate glass, soda lime glass with Cerium) on fully automatic machines ensuring total uniformity of production.
Tips and tapers are centred and can be checked by rolling the pipettes on a flat surface. Length and taper of the tips are carefully controlled. Constrictions for plugging are neatly formed at a uniform distance from the fire polished end.
Constrictions are heat formed which avoids weaknesses or contamination of the glass found when moulding or tooling processes are used (ISO7712).download more info
