Plastic Test Tube 12×75 mm – Disposable Tubes for Laboratory Use

The plastic test tube 12×75 mm is a standard disposable tube widely used in medical and diagnostic laboratories for handling, storing, and analyzing biological specimens. These tubes are made from durable, clear polypropylene or polystyrene, ensuring high visibility and resistance to breakage during routine lab procedures.

With a 12 mm diameter and 75 mm height, the plastic test tube 12×75 mm offers a convenient volume capacity typically ranging between 4 to 5 ml, making it ideal for sample collection, centrifugation, reagent mixing, and short-term storage.

Designed for one-time use, these tubes are available in sterile and non-sterile formats. The sterile version is individually wrapped or packaged in packs, suitable for sensitive applications such as blood collection, microbiological testing, or molecular diagnostics. The non-sterile type is perfect for routine lab tasks or educational use.

The tube’s smooth interior minimizes sample retention and ensures accurate volume readings. Its round bottom allows for easy mixing and complete sample retrieval, especially in centrifuge processes. Additionally, the plastic material offers chemical resistance and is compatible with most biological fluids and reagents.
