Borosilicate 3.3 glass according to ISO 4796.

• High resistance to chemicals and thermal shock
• Available in capacities from 10 to 2000 ml
• Hollow glass stopper and ground joint

These reagent bottles have a precise ground neck to ensure a water- and air-tight connection between the bottle and the glass stopper. All components are made from borosilicate 3.3 glass and are, therefore, ideal for the storage of aggressive and hot media.
