Mettler Toledo Presents RAININ Pos-D

The World's First Positive Displacement Pipette with Ergonomic Features

January 9, 2009- RAININ, a Mettler Toledo company, presents Pos-D, the world's first positive displacement pipette with ergonomic features. With this pipette, RAININ ensures proper handling and dispensing of fluids that are otherwise difficult to aspirate and dispense correctly.

Non-aqueous solutions-namely those that are viscous, dense, or high in vapor pressure-are difficult to aspirate correctly when using regular air-displacement pipettes. RAININ's Pos-D pipette overcomes this challenge by ensuring that the necessary pressure equalization to handle such solutions exists within the pipette tip. For example, a volatile liquid, which would otherwise evaporate and, consequently, force some of the sample out of the pipette tip, remains intact with the Pos-D pipette because of such adequate pressure equalization.

Problems associated with dispensing can lead to very serious, costly errors in the laboratory. With the Pos-D pipette, such problems are kept to bare minimum - thereby yielding more accurate and precise results. The disposable piston, which is embedded within a plastic capillary, makes direct contact with all liquid contents found inside the pipette. This ensures that the given sample is completely dispensed, without a single droplet of residue being left behind. It also means that instrument contamination is completely avoided, as the piston can be disposed of after use.

The Pos-D pipette is designed with ergonomic benefits in mind. Equipped with a large handle, the pipette feels natural and fits comfortably in the hand. The ergonomic finger-hook eliminates the need to grip the pipette firmly, allowing it to rest comfortably in the hand. Finally, the volume control setting faces the user, making the Pos-D pipette visible at all times and helping users avoid any awkward twisting.
