100mL Bio-Reaction Tubes with .22um Vent Cap, Polypropylene, RNase and DNase Free, STERILE, Bagged, 25/Pk, 300/Case

Our 100 mL Round Bottom Bio-Reaction Tubes provide a scalable, economical solution for high-density suspension cell culture, microbial fermentation, and small-volume bioprocess development. Each tube features a 0.22 µm hydrophobic PTFE vented membrane cap, allowing sterile gas exchange while preventing liquid and aerosol contamination — delivering bioreactor-like performance in a compact format.

• Optimized for Suspension Cell Growth & Bioprocessing
  Ideal for mammalian cells, bacterial cultures, bioreactor seeding, and small-scale reaction testing.
• 0.22 µm Hydrophobic PTFE Membrane Vent Cap
  Ensures sterile air exchange while blocking fluid ingress and contaminants; chemically resistant and heat stable.
• Increased Working Volume – 100 mL Capacity
  Supports longer culture durations, higher biomass yield, and smoother scaling to shake flasks or benchtop bioreactors.
• Round Bottom Dual-Use Design – Culture & Centrifugation
  Enables direct centrifugation for harvesting or clarification without transferring samples.
• High-Purity Polypropylene Construction
  RNase- and DNase-free, non-pyrogenic, and resistant to common reagents and temperature fluctuations.
• Easy Identification & Measurement
  Includes clear black graduations and a large white writing area for sample labeling.
• High-Speed Centrifugation Compatible
  Withstands up to 16,000 × g (round bottom configuration).
• Sterile, Resealable Bag Packaging Only
  Gamma-irradiated and individually packaged in sterile, zip-closure/resealable bags — no foam rack format.
• Optional Vent Control Labels
  Adjust oxygen transfer by selectively covering 1–5 PTFE vent holes for different culture needs.
