Precision-molded from premium grade polystyrene, this 12 x 75mm Sterile Polystyrene Culture Tube from Globe Scientific delivers 5 mL capacity with a dual-position LDPE snap cap for flexible aerobic and anaerobic sample storage.
For laboratories processing high volumes of culture work, the Globe Scientific 110428 withstands centrifugation up to 1500 RPM and operates across a temperature range of -20°C to 70°C, providing crystal-clear visibility for visual sample assessment.
Manufactured under cleanroom conditions and gamma-irradiated for guaranteed sterility, each tube features a attached dual position snap cap that provides either vented airflow for aerobic cultures or a sealed environment for anaerobic work — eliminating the need for separate caps or parafilm.

Frequently Asked Questions
What is a 12 x 75mm polystyrene culture tube used for?
A 12 x 75mm polystyrene culture tube with 5 mL capacity is used for sterile cell culture, microbiology, and clinical sample storage. The dual-position snap cap allows either aerobic or anaerobic sample storage in a single tube.
Are polystyrene culture tubes autoclavable?
No, polystyrene culture tubes are not autoclavable. They can withstand temperatures up to 70°C. For applications requiring autoclaving, choose the polypropylene (PP) version instead.
What is the difference between PS and PP culture tubes?
Polystyrene (PS) culture tubes offer crystal-clear visibility and withstand 1500 RPM centrifugation, with a temperature range of -20°C to 70°C. Polypropylene (PP) tubes provide greater impact resistance, withstand 3000 RPM, and are autoclavable and freezable (-80°C to 121°C). LabSupplies.com stocks both materials from Globe Scientific.
