Hollow stoppers, hexagonal plate, glass
Glass stopper for tight sealing of standard ground vessels, DIN 12 252.
Hollow stoppers, hexagonal plate, pointed bottom, borosilicate glass 3.3
Acc. to DIN 12252, form C.
LLG-Hexagonal hollow stoppers, borosilicate glass 3.3, pointed
For closing glassware with standard ground joints. The drip tip ensures that adhering liquid flows back into the glassware. Hexagonal shape prevents the stopper from rolling away. Acc. to DIN 12252.
NS-Glass stoppers, hollow borosilicate glass 3.3
Manufactured from borosilicate glass 3.3 which is resistant to heat and almost all chemicals. They meet the highest quality standards according to DIN 12252. Lower closed end of stopper features a "drip-tip" to ensure adhered liquid is returned to the flask. Hexagonal flat head prevents the stopper from rolling and allows stopper to be stood on end preventing contamination of the ground surface.
