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
Genesee Scientific Corporation Olympus 2.0ml Microtubes, Clear, No Cap
Olympus 2.0ml capless microcentrifuge tubes are identical to Olympus's capped version (cat# 22-283) in every way except for the lack of a cap. They are ready for autoclaving at 121ºC for 15 minutes. The tubes are exceptionally clear and can be used in any centrifuge up to 20,000 x g.

Research Products International Corp 5ml Sample Prep Tube, Conical, Natural, 200 per Case
Ideal alternative to using larger conical tubes when working with volumes less than 5 ml. This smaller tube allows only the tip to be exposed to the sample being withdrawn and eliminates inserting the pipettor barrel inside tube. Made from high quality polypropylene that can be autoclaved, boiled and stored at -80°C. Tubes withstand centifugation to 14,000 rpm and fit rotors that accommodates 15 ml tubes. Feature molded graduations and a frosted writing surface on the cap. Optional cardboard storage box available.
