What is a variable pipette?
Variable Volume Pipette Set Hach’s new variable volume single-channel, air-displacement pipets feature robust design, comfortable ergonomics, slim-line tip ejection, and single-handed operation. Outstanding accuracy with adjustments in 50 µL increments (0.05 mL). Ideal for use with HACH TNTplus reagents.
Are electronic pipettes worth it?
They swiftly revolutionised the handling and measurement of reagents in labs. Everyone who has used an electronic pipette to date can vouch for their precision and performance but research suggests that they enjoy just 10% of the market share.
What are the common types of Pipettes?
Common pipettes
- Air displacement micropipettes.
- Positive displacement pipette.
- Volumetric pipettes.
- Graduated pipettes.
- Pasteur pipette.
- Transfer pipettes.

What are Pipettes used for in science?
About Pipettes. A pipette is a laboratory instrument used to measure out or transfer small quantities of liquid, in volumes of milliliters (mL), microliters (μL).
Which pipettes are most accurate?
volumetric pipette
The volumetric pipette remains the world’s most accurate.
What is the use of pipette in chemistry lab?
How do you set up a pipette?
Put the pipette—held at 10–45 degrees—against the wall of the receiving chamber, and smoothly depress the plunger to the first stop. Wait one second and then depress the plunger to the second stop. Slide the tip up the vessel wall to remove the pipette. Allow the plunger to return to its rest position.
Is a pipette more accurate than a Buret?
• Release mechanisms are different in pipettes and burettes; burettes have a stop cock at the bottom while a pipette has a dropper like system that releases liquid in desired amount by lessening the vacuum. • Pipettes are believed to be more accurate in releasing liquid in smaller quantities than burettes.
How to use pipette correctly?
Ensure temperature equilibrium: Make sure the pipette,tips and liquids are at room temperature (if experiment allows)
What is the function of a volumetric pipette?
The specific function of a volumetric pipette is to collect a precise amount of liquid material and then transfer it into another container. For example, a volumetric pipette comes in a 20ml, 50 ml or 100 ml capacity so you can choose the one that is specifically needed for an accurate transfer of material.
What are volumetric pipettes used for?
A volumetric pipette, like a volumetric flask, is used to measure and dispense one specific quantity of liquid to add to another. Several different sizes are available to measure a predetermined amount of liquid, with popular sizes being 10, 25 and 50 milliliters. Volumetric pipettes are most often used in titration experiments.
