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

To provide easy implementation into your existing instrumentation, TriContinent air displacement pumps feature the following: Excellence is built right into our designs. Our pipetting pumps feature the following benefits, to name just a few: Pipette robots are capable of manipulating the pipettes as humans would do. [14] Calibration [ edit ] Alternatively, a consultation visit from one of our highly experienced product specialists is available for this range. Typically our specialist will be able to go through the following aspects with you to help you make the right choices and be able to deliver them on time and and on budget.P10– These tips are transparent (white). They have a volumetric range between 0.5 to 10 microlitres.

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. 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] Eppendorf Pipette: These are similar to micropipettes and are commonly used in molecular biology and biochemistry labs. Here is a list of different types of pipettes based on their use, and their shapes. Blowout Pipette 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?When choosing instruments for life science processes, reliability and precision are the foundation of accurate diagnostics. Seamless Integration Pipettes are usually calibrated with distilled water, at room temperature. It may be useful to recalibrate them when pipetting liquids with different physical properties (specific gravity and vapor pressure). A special pipette used in measuring viscous fluid such as whole blood. Common in medical technology laboratory setups together with other pipettes. Invented by Friedrich Wilhelm Ostwald, a Baltic German Chemist and later refined by Otto Folin, an American chemist. [7] [ failed verification] Winkler–Dennis gas combustion pipette [ edit ] These pipettes have two small continuous bands located on the upper end of the pipette. These pipettes will dispense even the last drop of liquid into the receiving container. Chemical Analysis: Pipettes are commonly used for chemical analysis, such as titrations and sample preparation for spectroscopic analysis.

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. The first thing you should decide is whether you need a manual or an electronic pipette. Manual pipettes are widely used and are great tools, but if you have the budget, then an electronic pipette will pay for itself in the long term, because it offers five significant advantages: Proper pipetting posture is the most important element in establishing good ergonomic work practices. [16] During repetitive tasks such as pipetting, maintaining body positions that provide a maximum of strength with the least amount of muscular stress is important to minimize the risk of injury. A number of common pipetting techniques have been identified as potentially hazardous due to biomechanical stress factors. Recommendations for corrective pipetting actions, made by various US governmental agencies and ergonomics experts, are presented below.

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.
