**100 Pack** CRY04/2RB 2.0 mL Sterile Round-Bottom Tube with Graduations – Polypropylene, Ultra-Clean, –196 °C to 121 °C, Bulk 100-Pack

Straightforward and performance-focused, the CRY04/2RB Tube is a 2.0 mL round-bottom polypropylene tube, perfect for ultra-clean laboratory workflows. Measuring 12.5 × 49 mm, it’s sterilised via gamma irradiation and certified free of DNase, RNase, and DNA—for pristine sample environments.

Engineered to endure extreme conditions, this tube handles centrifugation up to 17,000 × g and spans temperatures from –196 °C (in vapor-phase liquid nitrogen) up to 121 °C—adaptable enough for cryogenic storage and hot-plate incubation alike. Each comes individually sealed and is compatible with screw caps featuring silicone gasket and external thread.

Offered in packs of 100, these tubes deliver process-ready reliability right out of the box.
