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

Foxx Life Sciences EZBio MTO Centrifuge Tube Assembly, 50mL, Polypropylene (PP) Centrifuge Tube, Sampling Tube, Single Use Technology with EZBio Tubing and Pinchpipe, Vented with Diptube, CPC Aseptiquik (AQS), Sterile, 10/CS

The sterile EZBio Centrifuge Tube Assembly is a single use closed loop system designed for aseptic sampling and sterile transfer.
All components are USP Class VI resin, assembled in a Class 7 cleanroom, and gamma-irradiated in the USA. These assemblies feature a closed cap, an 18” inlet line (1/8” x 1/4” TPE tubing) with a pinch clamp, pinch pipe, plug or luer or CPC MPC/AQS, a 1.5” vent line with PTFE hydrophobic filter, and a dip tube. A centrifuge tube stand securely holds either size. The polypropylene resin meets FDA and USP standards.
