Types of Serological Pipettes and Their Uses

Serological pipettes are used in laboratories to transfer liquids. These pipettes have graduations on the side that help measure the amount of liquid to be dispensed or aspirated (in milliliters or milliliters). They are most recommended as they are very accurate in measuring the smallest incremental levels.

Serological pipettes are mainly used in the following areas:

✦ mixed suspension;

✦Combining reagents and chemical solutions;

✦Transfer cells for empirical analysis or expansion;

✦layered reagents for creating higher density gradients;

There are three different types of serological pipettes:

1. Open pipette

Open-ended pipettes with exposed ends are best suited for measuring highly viscous liquids. The pipette's fast fill and release rates make it ideal for handling fluids such as oil, paint, cosmetics, and sludge.

The pipette also features a fiber filter plug that helps reduce fluid contamination. Open-ended pipettes are pyrogen-free pipettes that have been gamma sterilized. They are individually packaged in thermoformed paper/plastic to prevent damage.

These pipettes are available in 1 ml, 2 ml, 5 ml and 10 ml sizes. They must comply with the ASTM E1380 industry standard.

2. Bacterial pipette

Bacterial pipettes are specifically designed to examine milk and other dairy products. These polystyrene milk pipettes are available in 1.1 ml and 2.2 ml sizes.

These are non-pyrogenic disposable pipettes that are sterilized using gamma radiation. They come in thermoformed paper/plastic packaging to avoid damage. These pipettes include a fiber filter to protect fluids and liquid samples from contamination. Bacterial pipettes must meet ASTM E934 standards and be calibrated to provide a (TD) of +/-2%.

3. Straw

The pipette is completely transparent and has no graduation. They are specifically designed to transport and mix fluids in different applications such as vacuum or pipette aspiration processes. They are disposable, pyrogen-free, non-clogging polystyrene pipettes.

These pipettes are wrapped in thermoformed plastic to avoid contamination. They are sterilized using gamma rays and meet the Sterility Assurance Level (SAL).
