Tubes for Every Centrifugation Need
From 0.5mL microcentrifuge tubes for DNA prep to 50mL conicals for cell culture, plus centrifugal concentration filters with MWCO cutoffs from 5kDa to 100kDa. All tubes are RCF-rated and available in sterile options.
TUBE GUIDE
Which tube do you need?
| Type | Volumes | Cap Style | Best For |
|---|---|---|---|
| Microcentrifuge | 0.5–2.0mL | Lid-Lock, Snap, Screw | DNA/RNA prep, enzyme reactions, sample storage |
| Conical (15mL) | 15mL | Screw Cap | Cell pelleting, reagent mixing, sample collection |
| Conical (50mL) | 50mL | Screw Cap | Cell culture, media prep, large-volume centrifugation |
| Centrifugal Filter | 15mL | Screw Cap | Protein concentration, buffer exchange, desalting |
| Ultracentrifuge | 10–30mL | Screw Cap | Ultracentrifugation, density gradient separation |
💡Choosing a MWCO Cutoff
Select a molecular weight cutoff (MWCO) that is 2–3x smaller than your target protein. For example, to concentrate a 50kDa antibody, use a 10kDa or 30kDa filter. This ensures retention while allowing smaller contaminants to pass through.
FILTER MWCO OPTIONS

🛡️Sterile vs. Non-Sterile
All conical and microcentrifuge tubes are available sterile. Centrifugal filters are sold non-sterile but can be UV-treated before use. Choose sterile tubes for cell culture, clinical samples, and any application requiring aseptic technique.
FREQUENTLY ASKED
Centrifuge Tube FAQ
Our 15mL and 50mL conical tubes are rated to 12,000×g (RCF). Check the product specification sheet for the exact rating for each tube type. Ultracentrifuge tubes are rated for much higher speeds.
Yes. Our polypropylene microcentrifuge tubes withstand autoclaving at 121°C/15 psi. Screw-cap tubes maintain seal integrity through autoclave cycles.
Metal-free tubes are manufactured with ultra-low heavy metal content, making them suitable for trace metal analysis, ICP-MS sample prep, and other metal-sensitive applications.
Lid-lock caps are fastest for routine use (snap open/close). Screw caps provide the most secure seal for sample storage, shipping, and applications involving volatile compounds or high-temperature incubation.
