Eppendorf is the name registered against a leading international instrument manufacturing company. What are Micropipette tips Multichannel electronic pipettes combine the efficiency of multiple heads with the ergonomic benefits of automation. The use of both technologies can drastically boost efficiency when microplate filling. In many cases, the time needed to complete the task can be reduced to less than a minute.

A variety of devices have been developed for safer, easier, and more efficient pipetting. For example, a motorized pipette controller can aid liquid aspiration or dispensing using volumetric pipettes or graduated pipettes; [11] a tablet can interact in real-time with the pipette and guide a user through a protocol; [12] and a pipette station can help to control the pipette tip immersion depth and improve ergonomics.

Designed with precision in mind, micropipettes allow scientists to accurately extract, transport and dispense liquids in the microlitre range. Micropipette capacity ranges from between 1 and 1000 microlitres. Macropipettes are designed for larger quantities and offer a capacity range of between 0.25–5 mL.

The pipette is made of a carbon shell, within which is an alloy of gold-germanium. The pipette was used to learn about how crystallization takes place. [10] Pipette aids [ edit ]Over the decades, manufacturers have developed a variety of different pipettes for specialised applications. Today pipettes come in a myriad of designs, with precision and accuracy varying greatly between models. Below, we list some of the most common pipettes found in laboratories.

When you're repeat dispensing multiple aliquots, you should discard the first and last dispense of the series, as they have the largest associated volume errors.A plastic pipette is a disposable pipette. You can not use it again and again just like a glass pipette. As they are used for the transfer of liquids that are infected so these pipettes are discarded after use to maintain biosafety protocols. Better precision and accuracy – as they are less operator-dependent. You can also save pipetting protocols to reduce manual errors and prevent operator-to-operator variability. Pipettes are typically made of glass or plastic, and are designed to be chemically resistant to the liquids they are used to transfer. They can be made from borosilicate glass or plastic materials that can withstand changes in temperature and exposure to different chemicals. Pipette Accuracy A pipette (sometimes spelled as pipet) is a type of laboratory tool commonly used in chemistry and biology to transport a measured volume of liquid, often as a media dispenser. Pipettes come in several designs for various purposes with differing levels of accuracy and precision, from single piece glass pipettes to more complex adjustable or electronic pipettes. Many pipette types work by creating a partial vacuum above the liquid-holding chamber and selectively releasing this vacuum to draw up and dispense liquid. Measurement accuracy varies greatly depending on the instrument. Aimee Cunningham (2007-04-18). "A New Low: Lilliputian pipette releases tiniest drops". Science News. Vol.171. pp.244–245.
