Low-density polyethylene (LDPE) makes these sterile pipettes with built-in bulbs the perfect substitute for breakable glass pipettes, eliminating cross-contamination and cumbersome rubber bulb changes. Plastic reduces the loss of cells and proteins that often occurs with binding that takes place with glass alternatives. Precision manufacturing ensures uniform repeatable drops.

Heat seal pipettes to provide liquid-tight transport and storage. These pipettes are suitable for use within a temperature range of -58 to 194°F (-50 to 90°C). Come sterile and individually wrapped.
