PS, non-sterile. Strongly lipophilic / hydrophobic. For solid phase with hydrophobic molecules and liquid phase with hydrophilic molecules, resp. Modification via a physical-chemical process, good shelf life at room temperature. Clearly distinguishable through the colour code: blue embossed alphanumeric coding for 96-well standard plates. Free from endotoxins, DNase, DNA, RNase, non-cytotoxic. PS, non-sterile. Strongly lipophilic / hydrophobic.
