Frequently Asked Questions
What RCF can these centrifuge tubes withstand?
Polypropylene Diamond MAX tubes are rated for high-speed spins typical of benchtop protocols. The 50 mL and 15 mL conical formats tolerate routine pelleting forces; confirm your rotor's maximum rating against the specific tube for your application.
Are the tubes supplied sterile?
Yes, the Diamond MAX tubes are supplied sterile and ready for cell culture, sample collection, and assay setup without additional autoclaving before first use.
What is the difference between the multiple 50 mL SKUs?
SKUs 6297, 6298, and 6299 are all 50 mL Diamond MAX tubes with attached red flat caps, differing by configuration and case quantity. Pricing reflects each option; select the SKU matching your required pack.
Can these tubes be used with organic solvents?
Polypropylene performs well with aqueous buffers, dilute acids, dilute bases, and alcohols. Acetonitrile compatibility is limited, and aromatic or chlorinated solvents are not recommended.
