VWR Pipette Controller: Accurate, Easy, and Safe Liquid Filling and Emptying in the Lab The VWR Pipette Controller is an essential pipetting aid that simplifies and streamlines the filling and emptying of volumetric or graduated pipettes. It provides an ergonomic and efficient alternative to mouth pipetting or using rubber bulbs, allows fine and precise control over liquid flow, and significantly contributes to safety when working with various substances in the laboratory. Principles of Operation and Efficient Use of the VWR Pipette Controller The VWR Pipette Controller operates on the principle of creating negative pressure (vacuum) to draw liquid into the pipette and positive pressure or gravity for dispensing. It is equipped with a small motor that allows controlled aspiration of air from the pipette, thereby drawing the liquid into it. It allows precise control of the aspiration volume and dispensing speed, which is critical for accuracy when working with volumetric pipettes and helps prevent common errors associated with less controlled manual methods. Using the VWR Pipette Controller is especially efficient when pipetting large volumes or performing long series of liquid transfers. It is lightweight and features an ergonomic design that supports comfortable, prolonged work. Furthermore, it is compatible with a wide range of glass or plastic pipettes of various volumes and provides a safe solution for filling and emptying liquids, including those that are toxic, corrosive, or have strong odors, without direct mouth contact. Key Applications of the VWR Pipette Controller in Laboratories The VWR Pipette Controller is a versatile tool with numerous applications in laboratories:
Solution and Reagent Preparation: Accurate measurement and transfer of large volumes (mL to tens of mL) when preparing culture media, working solutions, and reagents. Cell Culture Work: Gentle transfer of culture media, additives, and replacements, and washing cells in flasks or culture bottles. Chemical and Biochemical Assays: Precise transfer of specific volumes of samples and reagents for various analyses. Academic and Educational Laboratories: A basic and easy-to-operate tool for demonstrating principles of safe and accurate pipetting. Quality Control Labs: Accurate transfer of samples and materials for routine testing.
The VWR Pipette Controller is a compact investment that significantly improves efficiency, accuracy, and safety in laboratories performing routine or large-volume pipetting tasks.
