Alkali Scientific 50mL Bio Reaction Tube with Septum and PTFE .22um Vent Cap, Polypropylene, Bagged, Sterile, 10/Pk, 100/Case
Supplier: Alkali Scientific CBS5601
The 50 mL Bio Reaction Tube with Septum is designed for small scale suspension cell culture, microbial fermentation, and high throughput bioprocess development. It enables direct liquid addition or sampling using a syringe or injection needle without removing the cap, reducing contamination risk and improving workflow efficiency in automated or manual systems. The tube integrates a silicone pierceable septum with a 0.22 µm hydrophobic PTFE vent cap, allowing sterile gas exchange while maintaining closed system liquid handling. This design is suitable for cell line development, clone selection, media optimization, and recombinant protein expression workflows. The silicone septum supports repeated needle punctures and reseals after each insertion, enabling reliable sampling and reagent addition while maintaining aseptic conditions during culture and bioprocess experiments.
