Prevent cross-contamination with Thermo Scientific™ Samco™ General-Purpose Transfer Pipettes, which have a built-in bulb that eliminates the need for plugging, packaging and autoclaving. Samco transfer pipettes are made of shatterproof, nontoxic polyethylene. Their low-affinity surface reduces loss of cells and valuable proteins due to binding. They can be frozen in liquid nitrogen, or heat sealed for storage.
