We established a new class of safe screw cap tube which has proven its worth time and again. The particularly safe O-ring screw cap makes it a versatile piece of equipment. Ideal as a centrifuge tube, transport and storage tube, e.g. for high-grade synthesised oligonucleotides, enzymes and buffers. Clean room conditions, trained staff in protective clothing and automatic production processes are the prerequisites for the certified JSBIO quality standards PCR Performance Tested.
