Screw Cap Tubes come in different sizes. They range from 0.5 to 2 ml. They are available in a black color or ultra-clear.
Polypropylene screw cap tubes feature leak-proof silicone O-Rings and are ideal for sample processing applications. They also accept color-coded inserts that snap into the top of the caps, creating a flush surface. The tubes and caps are steam autoclavable and have been certified RNase-DNase-pyrogen-free. All of these features make sure that your samples are safe to handle.
Screw Cap Tubes are used for many different experiments, including patient sample collection. Some models have skirted bases for easier hand-free work. Screw caps are also available in a pre-sterilized, assembled version.
Screw Cap Tubes feature an O-ring that creates a positive seal to prevent leakage during processing, storage, and transport. Made of virgin polypropylene copolymer, the Screw-Cap Tube can withstand the G-forces of microcentrifuge instruments. This feature minimizes contamination and material hang-up and is ideal for any sample-processing application. If you work with sensitive or valuable samples, the Screw Cap Tube is a must-have for your laboratory.
