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

STEMCELL Technologies SepMate™-50 (IVD)
Simplify peripheral blood mononuclear cell (PBMC) isolation by incorporating SepMate™ into your density gradient centrifugation step. SepMate™ tubes contain an insert that creates a barrier between the density gradient medium and blood, thus eliminating the need for careful blood layering and allowing mononuclear cells to be easily harvested with a simple pour. This product can be used with RosetteSep™ to isolate specific immune cell subsets.SepMate™ is manufactured under cGMP and registered as an In Vitro Diagnostic (IVD) device in Australia, Canada, Europe, and the USA. In China, SepMate™ is considered a nonmedical device by the China Food and Drug Administration (CFDA) and should be used as general lab equipment. The end user is responsible for determining whether the product is suitable for their specific application.Browse our Frequently Asked Questions (FAQs) (https://www.stemcell.com/sepmate-faq.html) on SepMate™.
