CELLTREAT 229491 15mL Polystyrene Centrifuge Tube, Sure Cap - Bag, Sterile (500/pk)

The CELLTREAT 229491 is a 15mL polystyrene centrifuge tube, known for its clarity and optical transparency, making it suitable for sample viewing and colorimetric testing. These tubes come with high-density polyethylene caps that have a flat surface for easy labeling and feature a compressible liner ensuring a secure seal. The tubes are graduated in 0.5mL increments, allowing for precise volume measurements, especially useful for small volume quantification and pellet viewing. Packaged in a zip-closure bag, these tubes offer a convenient and practical alternative to traditional packaging methods. Each case contains 500 sterile tubes. These tubes are ideal for applications that do not require high-speed centrifugation, as polystyrene is less durable under those conditions compared to polypropylene options.
