Celltreat 229479 Standing Bio Reaction Tube – Sterile 50 mL (100 pcs)

Description

Product Overview

The Celltreat 229479 Bio Reaction Tube is engineered for laboratories that demand both sterility and versatility in a single consumable. Constructed from high‑grade polypropylene, the tube offers a robust 50 mL volume while maintaining a lightweight profile that simplifies handling. The self‑standing geometry eliminates the need for external racks during culture or centrifugation, reducing setup time and minimizing the risk of cross‑contamination. Each tube is sealed in a gamma‑irradiated zip‑closure bag, guaranteeing a sterile environment from the moment it leaves the package. The ultrasonically welded 0.22 µm hydrophobic membrane on the cap permits controlled gas exchange, essential for aerobic cell cultures, while preserving a barrier against microbial ingress. With a maximum relative centrifugal force (RCF) rating of 6,000 g, the tube can endure high‑speed centrifugation without deformation, making it suitable for a broad range of protocols, from simple bacterial growth to complex protein precipitation.

Usage

Designed for flexibility, the Celltreat Bio Reaction Tube excels in diverse laboratory settings. In microbiology labs, it serves as an ideal vessel for growing bacterial colonies, allowing researchers to monitor growth directly through the clear polypropylene walls. In cell culture facilities, the tube’s gas‑permeable membrane supports aerobic metabolism, while the sterile packaging ensures a contaminant‑free start. The tube’s self‑standing form factor enables direct placement into standard centrifuge rotors, eliminating the need for secondary holders and reducing the number of consumables required per experiment. Its compatibility with common laboratory equipment, such as vortex mixers, incubators, and autoclaves, further expands its utility. Whether performing small‑scale enzyme assays, preparing samples for downstream analytical techniques, or conducting high‑throughput screening, the tube provides a reliable, reproducible platform that integrates seamlessly into existing workflows.

FAQ

Can the tube be autoclaved for additional sterilization?

Yes, the polypropylene material tolerates standard autoclave cycles (121 °C, 15 psi) without warping, making it suitable for additional sterilization if required by your protocol.

What is the purpose of the 0.22 µm membrane on the cap?

The membrane permits controlled gas exchange, which is essential for aerobic cultures, while preventing microbial contamination, ensuring a sterile environment throughout the experiment.

Is the tube compatible with all standard centrifuge rotors?

The tube’s dimensions conform to common rotor specifications, allowing direct placement in most bench‑top centrifuges. Always verify rotor clearance for optimal safety.

How many tubes are included in a case?

Each case contains 100 individually packaged tubes, providing a convenient bulk supply for high‑throughput laboratories.

What temperature range can the tube withstand?

The tube is rated for use from -20 °C up to 120 °C, covering typical storage, incubation, and assay temperature conditions.
