Boil-proof tubes will not open during boiling. Composed of a homopolymer, tubes have ultrasmooth conical bottoms to allow 100% visibility and no sharp “gates” to cause cuts and scratches. Frosted side surface area for writing. Extremely accurate and visible graduation markings. Thin membrane in cap middle allows easy syringe penetration. Diamond polished molds allow tubes to be manufactured without contaminating releasing fluids.

• Maxymum Recovery® microtubes with ultra-smooth surfaces prevent adhesion of proteins and nucleic acids after long periods of storage
• Certified free from DNase, RNase and endotoxin

Tubes are autoclavable at 121°C (250°F), under 15psi of pressure for 10–15 minutes with drying. Certified RNase-, DNase-, and pyrogen-free.
