Multi-purpose design serves a broad spectrum of biotechnology laboratory requirements including the collection, processing, centrifugation, long-term storage, and OEM packaging/shipping of restriction enzymes or other DNA/RNA modifying reagents.
Cap features circular 3mm syringe port which is easily pierced for radioisotope labeling and fraction collecting. Uniform, thick-walled construction, with reinforced support collar, allows high speed centrifugation to 17,000xg. Inert, LN²-grade polypropylene protects critical sample viability at extreme temperatures ranging from +121°C to -195°C (LN² vapor phase).
Two-turn closure design ensures that tightening of unique screw-cap will uniformly compress O-ring against beveled seat, eliminating distortion and maintaining seal integrity. Engineered for adverse conditions, vials, caps and ethylene/propylene O-rings are highly resistant to chemical attacks, and may be autoclaved with caps loosened.
Molded-in volume lines and etched writing panels on vials and caps will not crack off or dissolve. External ribs on vials position and lock into serrated holes in metal BioStor™ Racks, allowing single-handed opening and closing of screw-caps.
Order Natural caps or RainbowPacks™ of 10 colors: white, grey, pink, red, orange, yellow, green, blue, violet, and brown. Sterilized packs of assembled caps and vials are inner packaged in bags of 50 with tamper-evident seal. Once seal is broken, bags can be resealed with zip-lock.
