Sterile E-Beam is free of Rnase/Dnase, DNA, Pyrogen, Endotoxin, ATP, PCR Inhibitor
100% virgin polypropylene resin specifically selected for high clarity and biologic applications
O-ring design, thickness and material selection have been optimized to provide protective features for maximum sealing ability, biologic interaction and temperature capability. The black colored O-ring is made from EPDM
Knurled caps improve grip when opening and closing tube
Frosted cap writing pad for easy product marking and identification
