LLG-PCR tubes with flat caps are suitable for standard PCR/qPCR thermal cyclers. The uniform, thin tube wall ensures optimum heat transfer and minimises condensation. The ergonomic cap design makes it easy to open and close the tubes with one hand. The V shaped bottom allows total sample recovery. LLG-PCR tubes are autoclavable as well as RNase-, DNase-, and pyrogen-free. Withstands centrifugation up to 18000 x g in a fixed-angle rotor and up to 500 x g in a swing-out rotor.
