All You Need To Know About Serological Pipettes

Commonly found and used in most laboratories, the serological pipettes are excellent tools for precisely measuring and transferring minute volumes of liquid with a good range of 1 milliliter to 50 milliliters. A serological pipette is available in multiple designs and different forms,  such as plastic, sterile, reusable, and glass. They provide you with multiple options for the laboratory. To give you a better understanding of what they are and what makes them a better option than standard pipettes,  we’ve made this helpful guide about the types and advantages of serological pipettes. We will be reviewing:


Types Of Serological Pipettes:

There are three primary types of serological pipettes. Each type of pipette is specifically designed for its respective applications. Here is a list:


Open-End Pipettes

Featuring an open-end, these pipettes are specially designed to allow quick and easy aspiration as well as dispensing. Especially when handling high viscosity liquids. Their fast filling and releasing rate is what makes them ideal for use with oils, cosmetics, paint, sludge, food, and cell culture applications. The material used for the manufacture of open-ended pipettes is polystyrene plastic, making them a safer alternative to glass pipettes. Due to the presence of a fiber filter plug located at the end of the pipette tip, Liquid vapor and fluid contamination to the pipettor and sample are majorly reduced with their use. Available in 1 mL, 2 mL, 5 mL, and 10 mL sizes, Open-end pipettes are non-pyrogenic pipettes sterilized by gamma irradiation and come separately covered in thermoformed paper/plastic peel packaging. 


Bacteriological Pipettes

Designed for use in the dairy field, bacteriological pipettes are standard for dairy examination. They are primarily used to examine dairy products, milk, etc. These polystyrene pipettes are sterile, non-pyrogenic, and appropriate for single-use. Coming in 1.1 mL and 2.2 mL sizes, these bacteriological pipettes are sterilized by gamma irradiation and utilize a fiber filter to prevent fluid and liquid-vapor contamination in samples and the pipette’s internal mechanism. 


Aspirating Pipettes

Unlike the other two types, aspirating pipettes are entirely transparent and do not have gradations. These pipettes are used in various applications, such as vacuum or pipettor aspiration procedures. They are non-pyrogenic, non-plugged polystyrene pipettes suitable for single-use and a safer alternative to glass Pasteur pipettes.

Like open-end and bacteriological pipettes, These pipettes also come wrapped in thermoformed covering to avoid contamination. Also, these pipettes have a remarkable sterility assurance level (SAL) of 10-6. (Universal Medical)


Advantages Of Serological Pipettes:

Now that you know about the different types of serological pipettes, you must know about the advantages Serological pipettes have to offer:

  • Available in single-piece structure

These pipettes are manufactured using one single smooth piece of FDA-grade polystyrene plastic, eliminating the need for solder joints common in other pipettes. Some pipettes come with welded tips and mouthparts in the pipette body. These “welded spots” are capable of causing errors by trapping liquid. On the other hand, Serological pipettes have a seamless design that eliminates the possibility of residual liquid. Also, this unique design provides a faster filling and release rate, ensuring the complete flow and higher accuracy.

  •  Easy to handle:

Serological pipettes have a shorter body than most other pipette types, making them easier to handle and move throughout the laboratory. You’ll experience that when working for long hours in the laboratory, it’ll be easier with serological pipettes.

  •  Convenient design:

Their flawless, specially designed tip can hold more viscous liquid, making them an excellent option for experiments that involve oils, paints, sludge, cell culture, etc. They have an inner diameter ranging from 1.56 mm for 1 mL to 4.50 mm for 25mL.

  • Packaging and compatibility:

Serological pipettes come pre-sterilized and are usually disposable. They are commonly available in pre-packaged bulk quantities between 25 and 50. All serological pipettes are specially designed to fit and work with electronic pipette controllers and pipettes, an excellent example of their universal compactness. (BALLYA)


To Wrap Up:

Keeping all this in mind, you can make a well-informed choice between standard and serological pipettes. Using Serological Pipettes for your experiments can make them precise and a

it’s a lot easier. To get the best Serological pipettes and pipette tips like Tecan Filter tips and numerous other products, visit Molecular Biology Products.
