Pipettes are manufactured from optical-grade polystyrene and feature a high internal and external surface polish, which reduces meniscus formation and helps ensure complete liquid expulsion.

Free of RNase, DNase, and pyrogens

Fine-line graduation printing further contributes to accuracy of at least ±2%. Each disposable pipette is cotton-plugged and color-coded to facilitate identification. Pipettes with ascending and descending graduations allow easy reading of both aspirated and dispensing volumes. Most pipettes feature an improved anti-drip tip design. All pipettes are RNase-free, DNase-free, pyrogen-free, and noncytotoxic.
