CELLTREAT 229433 50mL Centrifuge Tube - Black, Bag, Sterile (100/pk)

The CELLTREAT 229433 50mL Black Centrifuge Tubes, designed for efficiency and safety. These tubes are crafted to protect light-sensitive compounds, making it unnecessary to wrap them in aluminum foil, thus simplifying handling and ensuring integrity of your samples. The tubes feature a large, white marking area that provides stark contrast for easy identification and the flat surface polyethylene (HDPE) caps are straightforward to write on, enhancing usability. These caps include an integrated leak-proof seal, promoting secure sample containment.
For practicality in laboratory settings, these tubes are packaged in convenient zip-closure bags, a strategic choice over the traditional method of folding and taping bags, which can be cumbersome. This packaging not only protects the sterility of the tubes but also simplifies storage and handling. Each tube is autoclavable, non-pyrogenic, and free of RNase/DNase, certifying that they meet rigorous safety and quality standards. The primary material of the tubes is polypropylene, known for its durability and resistance to chemicals, with HDPE used for the caps.
