Is there a 20ml pipette?

Single, Class B, 20ml bulb form pipette, made of high quality borosilicate glass. Ideal for pipetting liquid substances from one vessel to another with accuracy.

What is a filtered pipette tip?

What is the purpose of a filter tip? Filter tips are used to prevent cross contamination or “carry over” from one sample to another. When samples are aspirated into a pipette tip, a fine mist or “aerosol” is created, which can get into the pipette.

When should you use a filter pipette?

Sterile Filter Tips: A filter tip is beneficial when the assay is sensitive to cross-contamination or the sample can contaminate the lower part of the pipette. The filter prevents liquid from splashing accidentally inside the pipette and aerosols from penetrating into the pipette tip cone during pipetting.

What is a 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 does a burette look like?

burette, also spelled buret, laboratory apparatus used in quantitative chemical analysis to measure the volume of a liquid or a gas. It consists of a graduated glass tube with a stopcock (turning plug, or spigot) at one end.

How would you set the volume to pipette 20 μl with the P20 pay attention to the decimal points?

Set the desired volume by turning the centrally located rings clockwise to increase volume or counterclockwise to decrease volume. P20: Maximum volume 20 μl. Accurate between . 5 μl and 20 μl.

How much do pipettes hold?

These disposable pipets are also called pipettes and work similar to an eye dropper or medicine dropper. Use them for quick, safe transfer of liquids. Each is 6 inches long and the tip is graduated to 1 ml and marked at . 5 ml.

What are filters in pipette tips made of?

plastic
Pipette.com Filter Tips are made with medical grade plastic and a robotically inserted 10 µm filter to provide precision and ensure protection when handling any sample.

Do you need sterile pipette tips?

Tips you’ve autoclaved yourself are sterile, which means that they are free from living organisms, but not necessarily from RNase and DNase. If you need to perform sensitive assays where this is required, you should opt for sterile tips from a manufacturer who can certify that their tips are free of RNase and DNase.

What is pipette tip used for?

Pipette tips are small, disposable tips that are made of molded plastic. Shaped like cones, a scientist attaches a pipette tip to the end of a pipettor and then uses it to transfer the liquid. The liquid used in the pipette tip is measured in microliters (μL), or one-thousandth of a milliliter (mL).
