Sorenson BioScience 0.5 ml Microcentrifuge Tubes Pack of 1000 Tubes

Sorenson BioScience Microcentrifuge Tubes – 0.5 mL, Natural Polypropylene, Graduated, Flat Snap Cap, Certified Nuclease-Free (MPN: 16890)

The Sorenson BioScience 16890 is a premium, molecular-biology-grade microcentrifuge tube engineered for secure small-volume liquid handling, centrifugation, and routine sample archiving. Precision-molded from high-clarity virgin polypropylene, these 0.5 mL (500 microliter) tubes combine exceptional chemical resistance with robust structural integrity. Every tube features an integrated flat snap cap designed to establish a positive mechanical seal, preventing accidental pop-open evaporation during thermal cycles or high-speed spinning. Calibrated with permanent, easy-to-read graduation marks, these non-sterile tubes are certified free of RNase, DNase, and external DNA contaminants, making them immediately ready for high-stakes genomics, clinical chemistry, and general research protocols.

Technical Performance and Design

• Secure Flat Snap Cap Design: Features an attached flat cap layout with a precise positive-locking rim. This configuration generates a hermetic mechanical seal that resists venting under intense centrifugal stresses and prevents evaporation during high-temperature water baths.

• Pristine Bio-Purity Profile: Manufactured under automated cleanroom conditions and validated to be entirely free of detectable RNase, DNase, human DNA, and PCR inhibitors, safeguarding fragile genetic targets right out of the bulk packaging.

• High-Clarity Polypropylene Build: Fabricated from premium, naturally hydrophobic virgin polypropylene resin that delivers outstanding visual transparency, letting technicians inspect fluid levels, color variations, and micro-pellets at a glance.

• Molded Volumetric Graduation Scale: Marked with clean, molded graduation intervals along the clear conical sidewall, supporting fast, convenience-driven sample volume monitoring and accurate serial dilution alignments.
