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

Alkali Scientific 50 ml, Centrifuge Tubes w/ rainbow caps, sterile, 25 per bag, 500/CasS
ASI's new SpectraTube™ is a new twist on a staple in the life science laboratory. We've taken the proven design of the 15 and 50ml conical tube and configured them conveniently in a foam rack with five different colored caps to make sample identification a breeze. These tubes are perfect for any lab conducting multiple studies, or any experiments requiring multiple sample types or solutions. All five cap varieties are flat, brightly colored, and frosted to make them easy to write on. 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 -45˚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 wit
