| Ultra-micro UV-Cuvettes are offered individually wrapped, DNA-, DNase-, RNase-free. However, because they have not undergone a sterilization procedure, they can not be called sterile. This is true of all disposable UV-transparent cuvettes on the market - none of them have undergone a sterilization procedure.
Autoclaving destroys the optical properties of the UV-Cuvettes. The caps are made of polyethylene, and as such can not be autoclaved. They are, however, manufactured under clean room conditions. |
