At the forefront of cell culture and bioprocess development, researchers are often troubled by such scenarios:
▶ Frequent sample transfer during small-scale suspension culture increases the risk of contamination.
▶ Traditional centrifuge tubes cannot control oxygen and pH in real time, and cell status is difficult to control.
▶ High-throughput conditional screening requires repeated disassembly and assembly of containers, which greatly reduces efficiency. Now, the game-changer is here! BKMAMLAB 50mL bio-reaction tubes - integrates four functions of culture, ventilation, centrifugation, and storage, redefining the boundaries of biological experiment containers!
Core breakthrough
1. Cell activity guardian
✅ USP Class VI polypropylene tube body + HDPE breathable cover, biocompatibility certified.
✅ 0.22μm PTFE filter membrane with a bacteria blocking rate of ＞99.99%, flower-shaped breathable cover, larger ventilation area.
✅ Conical bottom design, cell sedimentation is more concentrated after centrifugation.
2. Flux experiment accelerator
✨ Visualized uniform tube wall + scale line, real-time observation of cell density.
✨ Silk-screen writing area on the tube body, multiple groups of control experiment records are clear at a glance.
✨ 50mL standard specification, perfectly suitable for various culture plate racks and centrifuges.
3. Extreme environment conqueror
⚡Withstands 121℃ high temperature and high pressure, no worries about sterilization
⚡Can withstand maximum RCF: 18000Xg, with tolerance that is unrivaled among similar products
4. Compliance sterilization, ready to use
Gamma irradiation pre-sterilization, no DNA enzyme/RNA enzyme/pyrogen interference
(Note: The breathable membrane has a special structure, please do not sterilize repeatedly!)
Application Scenario
| Scenario | Problem solving | Effect improvement |
| Suspension cell culture | Transfer-free oxygen control and pH adjustment | Cell activity improvement |
| Monoclonal screening | Direct centrifugation to enrich target strains | High-yield strain acquisition efficiency doubled |
| Culture medium optimization | Multiple formulas parallel culture + centrifugation detection integration | R&D cycle shortened |
| Recombinant protein expression | Transfection-induction-lysis full process completed in a single container | Protein yield improved |
Key Operation Guidelines
▸ Pre-sterilized! Please open the lid in a clean bench
▸ Strong oxidants (such as concentrated nitric acid) may corrode the tube
▸ Check the balance before centrifugation to avoid >18000×g
