What Are the Different Kinds of Serological Pipettes?
Pipettes are usually made of glass or plastic. Due to safety and hygiene reasons, it is best to use single-use, polystyrene plastic serological pipettes.
1. Open-End Pipettes
Open-end pipettes come with an exposed end and are best suited for measuring high-viscosity liquids. The fast fill-and-release rate of the pipette makes it ideal for working with fluids like oil, paint, cosmetics, and sludge.
This pipette also comes with a fiber filter plug that helps reduce fluid contamination. Open-end pipettes are non-pyrogenic pipettes that are sterilized by gamma irradiation. They are packed individually in thermoformed paper/plastic for protection against damage.
These pipettes are available in 1 ml, 2 ml, 5 ml, and 10 ml sizes. They are required to meet industry standards.
2. Bacteriological Pipettes
Bacteriological pipettes are used specifically for the examination of milk and other dairy products. These polystyrene milk pipettes are available in sizes of 1.1 ml and 2.2 ml.
These are non-pyrogenic, single-use pipettes that are sterilized using gamma irradiation. They are packed in thermoformed paper/plastic to avoid damage. These pipettes include a fiber filter that prevents the contamination of fluid and liquid samples. Bacteriological pipettes are required to meet the standards and are calibrated to deliver (TD) at +/-2%.
3. Aspirating Pipettes
Aspirating pipettes are fully transparent and have no graduations. They have been specifically designed to transfer and mix fluids in different applications like vacuum or pipette aspiration processes. They are single-use, non-pyrogenic, non-plugged polystyrene pipettes.
