Multichannel pipettes are electronic devices used in scientific labs to accurately measure and fill multiple vials of liquid simultaneously. They save time, promote accuracy, and are commonly used in chemistry, pharmaceutical, and medical testing facilities. They work by controlling pull pressure and volume, and most models can fill 6 to 16 samples at once. They are usually expensive but pay for themselves in efficiency. They work by vacuum aspiration, and the scientist must program the device, connect the liquid chambers, and lower the tip of the vials into the sample liquid.
A multichannel pipette is an electronic device used in scientific laboratories to accurately measure and fill numerous vials of liquid at the same time. There are many different sizes and styles of multichannel pipettes, but they all serve a similar purpose: namely, to make pipetting easier, more efficient, and more accurate. Using this type of scientific equipment allows researchers and lab operators to ensure identical liquid withdrawals with the push of a button. This not only saves time and stress, but also promotes more accurate results and results.
Pipettes are common tools in places like chemistry labs, pharmaceutical research facilities, and medical testing centers where you need to accurately measure liquid. Most pipettes dispense the measured liquid into glass vials, usually drawing the liquid up with suction force to keep the contents stable and stable. Some of the more primitive pipettes require manual aspiration. More modern versions use basic electronics to control pull pressure and volume. In a multi-channel pipette, multiple vials are filled simultaneously.
There are many reasons scientists might want more samples of a given liquid. Most scientific experiments involve multiple tests on the same compound to understand reactions or identify particulates. To ensure consistent and usable results, it is important that scientists have equal amounts of liquid in each vial before starting an experiment. Inaccurate measurements can skew results.
A multi-channel pipette saves the lab technician the burden of laboriously filling and examining multiple vials. Most multichannel pipette models can fill 6 to 16 samples simultaneously. Scientists are able to control the precise amount to take, the suction pressure and the number of samples, among other things. A multi-channel pipette is usually an expensive lab piece of equipment, but it often pays for itself in efficiency.
There is usually not much functional difference between a multichannel pipette and a regular electronic pipette other than the number of vials attached. A multi-channel pipette is often a larger piece of lab equipment, but usually works in exactly the same way. First, the scientist must program the device by telling it how much to draw. This number is usually a precise volume, often measured to several decimal places.
Next, the scientist has to connect the liquid chambers to the base of the pipette. Most of the time, these chambers are in the form of sealable glass vials, although sometimes plastic is used for very temporary experiments. In a multichannel model, vials are inserted into special wells on the device, usually lined up in rows.
When the pipette is ready, the scientist lowers the tip of the vials into the sample liquid. With the push of a button, the pipette begins drawing liquid, stopping when it reaches the programmed volume. The finished vials can then be ejected into a storage tray and the pipette refilled. Most multi-channel pipettes can store previous commands and programs to quickly recreate results.
The vast majority of multichannel pipette designs work with the use of vacuum aspiration. This is essentially a windage method of volume control. A piston or plunger located inside the pipette moves up and down, creating a seal that draws liquid into the vial, then seals it there. This ensures a uniform volume by eliminating air bubbles.
