Ideally suited for all applications with samples that contain detergents: PCR and real-time PCR preparation of enzyme solutions and master mixes. Isolation, purification and denaturation of proteins. Restriction digestions and ligations. Pipetting DNA ladders during gel electrophoresis. Features: Ultrahomogeneous surface for maximum reproducibility. Ultrahydrophobic surface for minimum loss of sample. Air bubbles and foaming are signifcantly reduced during pipetting. Autoclavable, high chemical resistance - 5 year shelf life. Simple differentiation of racks and reloads through a new, clear lid with a white seal. When open, the text LoRetention can be seen from the inside. The reusable seal makes it also possible to label existing ep T.I.P.S. boxes. PCR clean, sterile, pyrogen-free. 10 x 96 tips.
