Frequently Asked Questions
Are these microcentrifuge tubes supplied sterile?
No. These tubes ship non-sterile. Labs requiring sterile conditions can autoclave the polypropylene tubes prior to use following their validated cycle.
Can the polypropylene tubes be autoclaved?
Yes. Polypropylene withstands standard autoclave cycles at 121°C, so the tubes can be steam-sterilized before sensitive applications.
What is the working volume of these tubes?
Each tube has a 1.8 mL capacity. Leave adequate headspace below the rim for capping, mixing, and centrifugation to prevent overflow.
How are the tubes packaged?
They are supplied 1000 tubes per bag.
