Serological pipettes are essential tools for precise liquid handling in laboratory settings. Available in reusable glass and disposable polystyrene, these pipettes are designed to aspirate and dispense liquid volumes using the blow-out method. They feature a narrow, transparent tube construction, often with clear, calibrated graduations for accurate measurement.
Key features of serological pipettes include:
Materials: Polystyrene or glass, ensuring durability and chemical resistance.
Sizes: Available in a wide range of volumes, typically from 1 mL to 50 mL.Graduations: Clear, bi-directional graduations for precise volume readings.
Sterility: Sterile options are available and certified free of RNase, DNase, human and bacterial DNA, and pyrogens, making them suitable for sensitive cell culture and molecular biology applications.
Packaging: Individually wrapped in either paper/plastic peel or plastic film packaging to maintain sterility. Options for cotton-plugged or non-plugged versions to prevent overfilling.
Compliance: Many pipettes meet or exceed standards such as USP VI, ensuring high-quality performance.
For example, the Thermo Scientific Nunc™ serological pipettes are known for their stringent quality specifications and user-friendly features. They come in various packaging options and are designed to work seamlessly with pipette controllers like the Easypet 3. Prices range from $37.65 for a case of 200 5 mL pipettes to $256.50 for a case of 100 50 mL pipettes
