What should you never do when using a serological pipette?

Understanding Serological Pipettes

  1. Don’t touch the sterile pipette with your hands or lay it on the table, this can lead to contamination.
  2. “Blown Out” is a common term used that means to empty the pipette in order to measure the correct volume.
  3. You never want the solution to go up into the cotton plug.

What is a pipette with bulb used for?

Pipette bulbs (also known as or pipet bulbs, pipetting balls or pipettor bulbs) are manual pipetting devices used to fill serological pipettes, volumetric pipettes or transfer pipettes.

Why would you use a serological pipette?

The serological pipette is frequently used in the laboratory for transferring milliliter volumes of liquid, from less than 1 ml to up to 50 ml. The pipettes can be sterile, plastic, and disposable or sterilizable, glass and reusable.

Is it safe to fill your pipette by suction?

In the not too distant past, chemists commonly used the pipette like a straw; putting their mouth on the open upper end and using lung power to suck up the solution at the other end, which is now considered a definite safety hazard and should never be done.

How do you read a serological pipette?

Measure using the bottom of the concave surface of the liquid in pipette. This figure illustrates how to read the meniscus on a measuring pipette. Liquid was drawn up to exactly the zero mark and was then dispensed. Reading the value at the bottom of the meniscus shows that 3.19 mL of liquid was delivered.

How do you use a serological pipette?

The Procedure for Using a Serological Pipette:

  1. Without opening the sterile sleeve, look through the wrapper and check that the pipette is calibrated as a ‘blow-out’ pipette.
  2. Open the wrapper and remove the pipette aseptically and insert the top, wide end into a pipette-aide.

Is a pipette A medical device?

Under the IVD Regulation (2017/746) mechanical and electronic pipettes and pipette tips are classified as products for general laboratory use. They can be used to perform in-vitro diagnostic procedures, but do not fall under the scope of in-vitro diagnostic medical devices.

What is serological pipette?

Serological pipettes are temperature calibrated laboratory tools that are the ideal choice for laboratories that need to transfer large amounts of liquid (1 mL to 50 mL).

What will happen if we hold pipette through bulb it will?

We should not hold the pipette by the bulb or below the bulb. This is because it is the weakest part of the pipette and holding will put stress through the bulb. If the pipette breaks while being inserted into the filler, sharp pieces of glass usually get embedded in one or both hands of a student.

What is pipette aspiration?

Knowing your pipetting angles makes all the difference. “Aspiration” refers to the process of uptaking the liquid into your pipette. When aspirating, the micropipette should be held at 90 degrees.

What is a Serological pipette?

Serological pipette is temperature-calibrated laboratory tools, ideal for laboratories that need to transfer large amounts of liquid (1 mL to 50 mL). A serological pipette is designed in a variety of different forms, including plastic, sterile, reusable, and glass, providing multiple options for the laboratory. 2. Material and specifications.

What is the difference between pipette pump and pipette bulb?

One type of dispenser, The pipette bulb offers the least amount of accuracy and is generally used with glass serological pipettes to transfer non-specific volumes of liquid. The pipette pump is also used with glass pipettes and allows a more precise regulation of the liquid volume.

What are the different types of pipettes?

The pipettes can be sterile, plastic, and disposable or sterilizable, glass and reusable. Both kinds of pipettes use a pipet-aid, for the aspiration and dispensation of liquids. Different sizes of pipettes can be used with the same pipet-aid for a variety of experimental assays.

What is a pipette used for in science?

Both kinds of pipettes use a pipet-aid, for the aspiration and dispensation of liquids. Different sizes of pipettes can be used with the same pipet-aid for a variety of experimental assays.
