Frequently Asked Questions
Will these caps fit standard 15 mL centrifuge tubes?
Yes. The 17 mm flange plug is sized to seat in both 17 mm tubes and standard 15 mL centrifuge tubes with a snap-fit closure.
Are these caps sterile?
No. SKU 6263G ships non-sterile. For sterile workflows, autoclave compatibility depends on your protocol; verify polyethylene temperature limits before sterilizing.
Are the caps autoclavable?
Polyethylene has limited high-temperature tolerance and is generally not recommended for repeated autoclaving. Use chemical disinfection or single-use practices for contamination control.
How many caps are in a case?
Each case contains 1000 caps. Pricing shown is per case, with tiered institutional and grant pricing available on request.
