Großvolumenpipetten

A Großvolumenpipette, or large-volume pipette, is a laboratory instrument designed for the precise measurement and transfer of relatively large volumes of liquid, typically ranging from milliliters to liters. Unlike smaller volumetric pipettes, which are calibrated to deliver a single, fixed volume, Großvolumenpipetten are often adjustable and can dispense a range of volumes within their specified capacity. They are constructed from materials such as glass or plastic, chosen for their chemical resistance and durability.

The design of a Großvolumenpipette typically involves a graduated cylinder or a piston-driven mechanism. Graduated pipettes have clear markings along the barrel to indicate different volumes. Piston-operated pipettes, often referred to as serological pipettes or macro-pipettes, utilize a plunger system to draw in and expel liquid. Many modern Großvolumenpipetten are designed for use with an auxiliary device, such as a pipette controller or a motorized dispenser, which facilitates accurate filling and dispensing and reduces the risk of repetitive strain injuries.

Großvolumenpipetten are essential tools in various scientific disciplines, including chemistry, biology, and medicine. They are commonly employed in tasks such as preparing large batches of solutions, diluting samples for analysis, and dispensing reagents in large-scale experiments or industrial processes. The accuracy and precision required for these applications necessitate careful calibration and proper handling techniques to ensure reliable results. Their use is particularly prevalent when the volumes involved exceed the capacity of standard laboratory pipettes.
