CENTRIFUGE TUBE: 50ML, WITH BLUE LID, GRADUATED, STERILE The 50 ml centrifuge tube with a blue lid is a high-quality laboratory container designed for reliable sample handling. Made from transparent polypropylene and sterilized, it features graduated tags and a blue screw cap for secure closure and easy identification.

Main Benefits

The transparent polypropylene construction provides excellent chemical resistance and optical clarity for sample inspection.
Sterilized, certified free from RNase, DNase, pyrogens, and other contaminants, ensuring sample safety.
Graduated tags (typically in 2.5 ml or 5 ml increments) provide accurate volume estimation.
The blue screw cap (flat surface or stopper) ensures leak-resistant closure and ease of labeling.
Some designs include a frosted white writing area for sample identification.
Capable of withstanding high centrifugal forces (varies by model) and compatible with standard rotors.

Components

Tube Material: Polypropylene (PP)
Cap Material: Polyethylene (PE) or High-Density Polyethylene (HDPE)
Graduated tags: Molded or printed with clear increments (e.g., 2.5 ml or 5 ml)
Sterilization: Sterilized by radiation or other methods; free from RNase, DNase, pyrogens, endotoxins, and cytotoxins (depending on the manufacturer)

Instructions for Use

Used as a centrifuge container for separating, preparing, or storing samples. The tube is intended for use under laboratory or veterinary supervision. A qualified specialist should determine the appropriate centrifugation parameters based on the type, sample type, and clinical or experimental conditions.

Package Size

Available in bulk packages, typically 25 or 50 tubes per bag or rack, with containers holding approximately 500 tubes in total, depending on the supplier.

Note

Some versions include a skirt with a flat base or stable base for standing without additional support. Certain models may offer enhanced features such as high-speed centrifugation rating, leak-resistant threads with vacuum system, or temperature resistance suitable for freezing or steam sterilization, depending on the specific model.
