Micropipette: These are used to measure very small volumes of liquid, typically in the range of microliters or even nanoliters. Although specific names exist for each type of pipette, in practice, any type can be referred to as a "pipette". [3] Pipettes that dispense less than 1000 μl are sometimes distinguished as micropipettes. Eppendorf Pipette: These are similar to micropipettes and are commonly used in molecular biology and biochemistry labs. This section needs additional citations for verification.

( July 2012) ( Learn how and when to remove this template message) Cell Culture: Pipettes are used in cell culture techniques for adding or removing small volumes of culture medium, which contains essential nutrients for the growth of cells.

Is the task repetitive? If so, ergonomically designed pipettes can be beneficial as they reduce fatigue and minimise the risk of errors that can jeopardise accuracy and precision. SciPette, our own brand of liquid handling products, has built a strong reputation for quality, durability, ergonomics and affordability among other serological pipettes and pipettors on the market. Starting with basic pipette pumps and manual pipettors, our range also covers fully digital pipettors, micropipettors and automatic liquid dispensing systems. Laboratory pipettes are purpose-built tools that allow scientists to transport liquid safely and precisely. Commonly used in biology, chemistry and medical laboratories, the piston-driven instruments resemble syringes and come in many different designs, ranging from basic single-piece glass pipettes to sophisticated electronic pipettes. Accuracy and precision can vary significantly between designs, with laboratories choosing pipettes based on their unique needs. Some pipettes are operated by hand while others feature automatic technology. How do laboratory pipettes work? Pipette Diagram: A pipette has a narrow end for transferring liquids and a bulb or other mechanism for drawing up the liquid.Reliability and accuracy are the most important factor diagnostic and life science instruments. Our automated and fully programmable air displacement pipetting pumps are a perfect fit for all standard pipetting applications.

It is very important to use a specific type of tip according to the volume of the liquid. Using any other tip can affect the accuracy. How to Clean Pipettes Properly Chemical Analysis: Pipettes are commonly used for chemical analysis, such as titrations and sample preparation for spectroscopic analysis. When immersing the tip into a liquid, it shouldn't be more than 2-3 mm below the surface, to minimize the amount of liquid retained on the outside of the tip. Pipetting viscous and volatile liquids with an adjustable volume air displacement pipette can be challenging but mastered with the right technique and pipette tip. Viscous liquids should be aspirated and dispensed slowly using reverse pipetting. Using this technique, a larger volume than needed is aspirated, which compensates for the retained liquid adhering to the inside of the tip. Low retention tips are the ideal option for viscous liquids, and for very high viscosity liquids, or those that tend to foam, wide bore tips are recommended. In a microbiology laboratory, you can use a pipette to transfer a specific buffer (chemicals that resist change in pH) during media preparation.Cleaning the outside of the pipette should be part of your daily routine. Simply wipe it with a lint-free cloth lightly soaked with 70 % ethanol.

The modular design of our pipetting pumps allows for a variety of configurations. This offers flexibility for numerous volume settings and mounting configurations. Precision glass syringes and our long-life seal technology add exceptional performance and unsurpassed longevity. A Host of Benefits Pipette Tips: The tips of a pipette are disposable and come in various sizes and materials. They are designed to fit onto the narrow end of the pipette and allow for accurate transfer of liquids. Pipette robots are capable of manipulating the pipettes as humans would do. [14] Calibration [ edit ]Micropipette tips are transparent or semi-transparent disposable tips that collect the liquid which is to be transferred. They come in different colors and ranges so have their respective names. 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.

https://www.pipettes.com/calibration-services/pipettes-university/accuracy-matters-blog/how-to-use-various-types-of-pipettes When pipetting volatile liquids, be sure to pre-wet the tip and use fast pipetting speeds for both aspiration and dispensing to minimize the effects of evaporation. Do not pause unnecessarily between aspiration and dispensing and use reverse pipetting to further reduce the effect of evaporation on the actual volume to be delivered.What type of liquid is being transported? Is it corrosive and is there potential to damage an unsuitable pipette? The viscosity of the sample can also determine what pipette lab equipment is used. Also known as variable volume air displacement pipettes, single-channel pipettes are extremely versatile and can be used for a variety of applications. Most offer a wide volume range of between 0 to 2500 microlitres. Depending on the application, scientists can choose to use adjustable of fixed volume single-channel pipettes. Pipettors are a form of pipette controller which enable the accurate drawing of liquid samples into a pipette. These devices also help to speed up the process of handling liquids and provide additional benefits by reducing hand-fatigue and the risk of contamination, to improve efficiency in the laboratory. We have a selection of pipettors and micro-pipettors (for smaller liquid volumes) to choose from, including variable and fixed-volume pipettors, multi-channel pipettors (for filling multiple pipettes at once) and more specialist devices where larger volumes of liquid need to be handled. Many of our products are autoclavable, to provide easy sterilization and remove contaminants, and they are supplied calibrated to ISO-standards for reliable accuracy when measuring precise volumes of liquid. SciPette digital pipettors are battery operated and able to be self-calibrated via a USB connection to a computer, removing the need for third-party calibration.
