Product Information

Pipette recalibration [15] is an important consideration in laboratories using these devices. It is the act of determining the accuracy of a measuring device by comparison with NIST traceable reference standards. Pipette calibration is essential to ensure that the instrument is working according to expectations and as per the defined regimes or work protocols. Pipette calibration is considered to be a complex affair because it includes many elements of calibration procedure and several calibration protocol options as well as makes and models of pipettes to consider. Integrated pipetting protocols – with pre-set or custom programs to minimize operator errors. Watch the video tutorials on our pipetting programs to see some examples. While compact and easy to use, single-channel pipettes can only be used to transfer one liquid sample at a time. This means they can be tedious and time consuming to use when multiple transfers are required.

The first micropipette was patented in 1957 by Dr Heinrich Schnitger ( Marburg, Germany). The founder of the company Eppendorf, Dr. Heinrich Netheler, inherited the rights and started the commercial production of micropipettes in 1961. Repetitive strain injury is one of the most common risks encountered by laboratory scientists. Electronic pipettes minimise the risk of injury by automating the air displacement process. Equipped with an internal motor, electronic pipettes offer the same accuracy and precision as their hand-operated counterparts but without the physical strain. Electronic pipettes are particularly useful when multi dispensing, a process that involves dividing a reagent into different doses. Serological Pipette: These are used in the medical industry to measure and transfer small volumes of liquid for medical testing. Positive Displacement Pipette: These are used to measure and transfer highly viscous or volatile liquids.Microfluidic pipette [ edit ] A Microfluidic pipette, housed in a manifold holder. The colored solutions highlight the solutions loaded into the wells of the PDMS pipette. Pneumatic actuation is used to keep all tubing free of contamination. An Eppendorf pipette is the same as a micropipette but it is specifically used to transfer to an Eppendorf tube. Eppendorf is the name registered against a leading international instrument manufacturing company. What are Micropipette tips

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.When choosing instruments for life science processes, reliability and precision are the foundation of accurate diagnostics. Seamless Integration

Graduated Pipette: These are used to measure and transfer different volumes of liquid, and have markings on the side to indicate the volume of liquid being measured. Here is a list of different types of pipettes based on their use, and their shapes. Blowout Pipette

Micro Pipette Calibration – Accumaximum". Archived from the original on 30 June 2013 . Retrieved 3 March 2016. 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 The type of task being performed is directly linked to pipette function in laboratory. Does the task require accuracy and precision, or is speed more important? The answer will determine what type of pipette is used. These pipettes operate by piston-driven air displacement. A vacuum is generated by the vertical travel of a metal or ceramic piston within an airtight sleeve. As the piston moves upward, driven by the depression of the plunger, a vacuum is created in the space left vacant by the piston. The liquid around the tip moves into this vacuum (along with the air in the tip) and can then be transported and released as necessary. These pipettes are capable of being very precise and accurate. However, since they rely on air displacement, they are subject to inaccuracies caused by the changing environment, particularly temperature and user technique. For these reasons, this equipment must be carefully maintained and calibrated, and users must be trained to exercise correct and consistent technique.

Pipet vs Pipette vs Micropipette: Is there any difference?". Microlit. 2022-04-21 . Retrieved 2023-05-23. 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 It has a different design than a typical micropipette. These pipettes allow the operator to aspirate the liquid only once and then dispense equal volumes into different vessels repeatedly. Eppendorf Pipette

The micropipette was invented and patented in 1960 by Dr. Heinrich Schnitger in Marburg, Germany. Afterwards, the co-founder of the biotechnology company Eppendorf, Dr. Heinrich Netheler, inherited the rights and initiated the global and general use of micropipettes in labs. In 1972, the adjustable micropipette was invented at the University of Wisconsin-Madison by several people, primarily Warren Gilson and Henry Lardy. [5] Improved ergonomics – minimizing the risk of repetitive strain injuries, as there's no plunger to press down to move the piston, and no need to twist knobs or the plunger to adjust the volume.
