Borosilicate Glass Media Bottles, GL32/GL45 Screw Cap, Dual Graduations — 50–1000 mL, 10/Box

The Globe Scientific Glass Media Bottles are autoclavable borosilicate vessels engineered for routine media preparation, reagent storage, and buffer dispensing across analytical and life-science workflows. Dual graduations let bench scientists verify volumes from either fill direction, while the GL screw-cap interface supports leak-resistant transport and repeated autoclave cycles without dimensional drift.

Frequently Asked Questions

Are these media bottles autoclavable?

Yes. The Type I borosilicate construction withstands repeated steam sterilization at 121°C. Loosen the screw cap before autoclaving to allow pressure equalization, then retighten after cooling.

What cap thread sizes do these bottles use?

The 50 mL bottle uses a GL32 thread, while the 100, 250, 500, and 1000 mL bottles use a standard GL45 thread compatible with common pouring rings and dispensing caps.

What do the dual graduations indicate?

Dual graduations provide volume markings readable from either fill orientation, allowing quick estimation when filling or decanting without rotating the bottle.
