PR1MA™ Microcentrifuge Tubes
PR1MA™ Microcentrifuge Tubes are engineered for durability, clarity, and performance in high-demand laboratory environments. Choose from two cap styles to suit your workflow - the boil-proof cap (MCT15) for high-temperature applications or the large boil-resistant cap (MCT17) for enhanced labeling and easy handling.
Constructed from crystal-clear polymer, each tube allows effortless sample visualization while ensuring maximum integrity during centrifugation up to 20,000 × g. The optional NoStick® low-retention resin prevents sample loss and ensures reliable recovery of precious materials.
Designed to endure extreme temperatures from –80°C to +121°C, PR1MA™ tubes are ideal for both cryogenic storage and autoclaving. Every tube is certified free of RNase, DNase, DNA, PCR inhibitors, and pyrogens — ensuring the highest standard of purity for molecular biology, PCR, and diagnostic research.
PR1MA™ Microcentrifuge Tubes deliver the clarity, performance, and confidence your lab depends on - from prep to preservation.
