Fixed Volume Pipettors

Fixed volume pipettors are precision instruments designed to dispense a specific, unchangeable volume of liquid with high accuracy and consistency. Unlike adjustable pipettors, which allow users to set different volumes, fixed volume pipettors are pre-calibrated for a single measurement, making them ideal for applications that require repeated dispensing of the same volume. They are commonly used in labs where precision and repeatability are essential, such as in clinical diagnostics, quality control, and high-throughput testing. Fixed volume pipettors are especially beneficial in laboratories that handle large sample volumes, reducing the time spent adjusting settings and recalibrating equipment. They are available in various volume capacities to accommodate different needs.

 

These pipettors operate using a piston-driven air displacement mechanism, ensuring accurate aspiration and dispensing of liquids. Because they do not require volume adjustments, they minimize user error and simplify workflows, particularly in environments where consistency is crucial. They are widely used in molecular biology, microbiology, and pharmaceutical research for tasks such as preparing standard solutions, loading samples into gel electrophoresis wells, and performing enzyme-linked immunosorbent assays (ELISA).
