Product Information

Budget will often play a role in the type of pipettes used in laboratories. Electronic pipettes are generally more expensive than their manual counterparts, which makes them more common in less technical laboratories. 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] Used in tissue and cell culture applications, serological pipettes are generally manufactured from glass or polystyrene. In laboratories where sterilisation is a priority, scientists will often use disposable pipettes made from durable plastic. Serological pipettes are also commonly used liquid dosages of more than 1mL.

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). Micropipette: These are used to measure very small volumes of liquid, typically in the range of microliters or even nanoliters. Here is a list of different types of pipettes based on their use, and their shapes. Blowout Pipette 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.This section needs additional citations for verification.

( July 2012) ( Learn how and when to remove this template message) Pipetting syringes are hand-held devices that combine the functions of volumetric (bulb) pipettes, graduated pipettes, and burettes. They are calibrated to ISO volumetric A grade standards. A glass or plastic pipette tube is used with a thumb-operated piston and PTFE seal which slides within the pipette in a positive displacement operation. Such a device can be used on a wide variety of fluids (aqueous, viscous, and volatile fluids; hydrocarbons; essential oils; and mixtures) in volumes between 0.5mL and 25mL. This arrangement provides improvements in precision, handling safety, reliability, economy, and versatility. No disposable tips or pipetting aids are needed with the pipetting syringe.

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. From high schools and universities to state-of-the-art research centres, pipettes are a staple in laboratories around the world. These small but highly practical instruments come in a variety of sizes, designs and capacities, with different pipettes used depending on the application. Below, we take a look at best-practice techniques for how to use a pipette in the lab. We also cover some important pipette facts, including the history of the instruments, types of pipette models and pipette laboratory apparatus uses. What is a laboratory pipette? 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.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. 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.

A pipette filler is a tool that is used to draw up liquid into a pipette without the need for a pipette bulb. It is a handheld device that is attached to the top of the pipette, and can be used to control the amount of liquid being transferred. Pipette Pump TriContinent pipetting pumps fully comply with ISO 13485 certification guidelines. They follow industry standard protocols to offer complete compatibility. Their lightweight and compact size allow you to save space when designing your OEM instrument. A Wealth of Options
