Centrifuge Tubes
Glass and plastic tubes designed for use in centrifuges; available in a variety of volume capacities, materials, configurations, RCF ratings, and closure types; may be sterile or non-sterile; may have graduations indicating volume on the tube.
Centrifuge tubes are used to contain liquids during centrifugation, which separates the sample into its components by rapidly rotating it around a fixed axis.
Most centrifuge tubes have conical bottoms, which help collect any solid or heavier parts of the sample being centrifuged. Centrifuge tubes must also be able to withstand the centrifugal pressure created during their use, and their specifications may indicate the maximum speed at which they can be safely used.
Centrifuge tubes are available in various styles, sizes, and materials
- Capacities: Range from 0.1mL to more than 100mL; the most common sizes are 15mL and 50mL (centrifuge) and 1mL and 2mL (microcentrifuge)
- Closures: Screw-on plugged or flat caps; may be attached or separate
- Markings: May have writing areas, graduations, or other markings
- Shape: Conical- or round-bottomed; if conical, choose skirted free-standing versions
- Material: Glass or plastic resin; the latter include polypropylene, polystyrene, PET, and PPCO
- Sterility: Sterile or nonsterile; may be heat- or gas-sterilized
- Packaging: Bulk or racked tubes
- Color: Choose amber or black plastics for light-sensitive samples

Electron Microscopy Sciences CULTRE TBE PS 5MM STRL 25 SEAL
Disposable sterile tubes with caps made of polyethylene (PE) and have the popular two position design (up/loose for aerobic work and down/sealed for anaerobic cultures). Polystyrene tubes may be centrifuged at up to 2000xg. Polypropylene tubes are able to withstand higher centrifugal forces, up to 4000xg.

Don’t let the pretty colors fool you! These conical 15mL and 50mL centrifuge tubes are made of premium polypropylene, with exceptionally uniform wall thickness for clarity and centrifugal strength. Tubes and caps may be used for sample storage at temperatures as low as -86°C. The maximum centrifugal forces are 12,000xg for the 15mL tubes and 15,000xg for 50mL version.* Tubes and caps are suitable for stem cell research and certified sterile, RNase, DNase, and Pyrogen free.*Refers to liquids with a specific gravity of 1.0, using appropriate rotors, cushions and adapters
CELLTREAT Scientific Products 50mL Centrifuge Tube, Red Cap - Bag, Sterile, 500/CS
CELLTREAT Scientific Products 50mL Centrifuge Tube, Red Cap. Graduations are printed in bold, easy-to-read black ink and are accurate to +/-2%. Large white marking area provides excellent contrast for identification. Easy to write on flat surface polyethylene (HDPE) caps feature integrated leak-proof seal. Polypropylene tubes include graduations molded into the conical bottom, ideal for pellet viewing and small volume quantification. Convenient zip-closure bag is a practical alternative to folding and taping opened bags. Assorted color cap tubes allow easily color coding of samples for quick identification, customization, and increased productivity. Users report coding each color to a day of the week, a member of the lab, or a specific procedure. Max RCF: 16,000g. RNase/DNase free and non-pyrogenic. Every case is printed with the lot number for quality traceability. Packaged sterile, 25/resealable bag, 500/case.
