Use the correct pipette for the volume you are pipetting. Micropipettes come in different sizes which have a specific range. Never adjust the volume beyond the upper or lower limit of this range, as it can compromise the accuracy of the experiment and the integrity of the pipette.

Category: LAB TOOLS. Sub-Category: GLASSWARE. A micro burette in engineering testing laboratories is a smaller, more precise version of a standard burette, used for dispensing very small volumes of liquid in titration or other precise liquid measurement experiments.

There are two main types of burette; the volumetric burette and the piston burette. A volumetric burette delivers measured volumes of liquid. Piston burettes are similar to syringes, but with a precision bore and a plunger. Piston burettes may be manually operated or may be motorized.

Both mechanical and electronic pipettes have their place in a lab. Mechanical pipettes are quick to take into use and can very easily be fully sterilized. Electronic pipettes speed up work and provide more consistent results throughout the day and between operators.

A burette delivers a variable, measured volume of liquid using a stopcock, while a pipette transfers a fixed, specific volume. Burettes are typically used for larger volumes and in processes like titration, as they have a scale and a stopcock for precise, adjustable dispensing. Pipettes are used for accurately transferring a set, often smaller, volume of liquid and require a suction device or filler to operate.

What is the working principle behind pipettes, and how do they ensure accurate liquid dispensing? Pipettes operate based on displacement principles. Air-displacement pipettes displace liquid with air, while positive-displacement pipettes use a disposable tip to directly displace the liquid.

Between 0.2 and 20 μL: Today, you can pipette small volumes (usually between 0.2 and 20 μL) with an accurate, tested, and proven technique. When working with these small-volume samples, it’s more common for errors to creep into the workflow.

Pipettes and micropipettes are invaluable pieces of laboratory equipment used to draw up, measure, and deliver accurate volumes of liquid. The difference between the two is that micropipettes measure volumes between 1 and 1000 µL, while pipettes generally start at 1 milliliter.

Efficiency. Filling microplates with a single-channel pipette can quickly become a very tedious and error-prone task. Using multichannel pipettes allows you to transfer multiple samples at once, increasing efficiency and preventing errors and repetitive strain injuries.
