High Borosilicate Volumetric Flask Class A Measuring

A volumetric flask is a container with a narrow neck, pear - shaped body and a flat bottom, equipped with a ground - glass stopper. There is a calibration line on the neck. It indicates that when the concave surface of the liquid coincides with the calibration line on the neck of the volumetric flask at the specified temperature, the volume of the solution is exactly equal to the volume marked on the flask. Marked on the volumetric flask are: temperature, capacity and calibration line. This product is an authentic SanAce item, a Class A volumetric flask that is guaranteed to pass inspection, and it is a "to - contain" type volumetric flask.

The flask body is made of thickened high - borosilicate glass.
The flask mouth has a standard ground glass joint.
Lids of the same standard are universally compatible. Usually, PE lids are used (they have excellent acid and alkali resistance and good sealing performance). You can also upgrade and purchase glass stoppers, which are also fully compatible and leak - proof. This completely solves the problem that traditional volumetric flasks cannot be properly stoppered after cleaning.
The printing on the flask body uses German high - borosilicate ink. It can withstand soaking in weak acids without peeling off.
Each flask has an independent laser - encoded number, which is matched with the corresponding calibration certificate.
The laser - engraved marking lines are more accurate.
