The Divided Reservoir - A Rethink

The majority of reservoirs have a plastic base that is built-in. This is discarded when you are done and creates a lot of unnecessary waste plastic. Developing a reusable and sturdy base that is compatible with a variety of reservoir inserts means that we are able to help you reduce plastic waste whilst at the same time saving you money.

Minimizing Dead Volumes

Dead volumes are a real problem, especially if you are using expensive reagents such as a PCR master mix. Other reagent reservoirs aim to minimize dead space by using V-shaped bottoms.

However, as soon as one of the tips of a multichannel pipette begins aspirating air, the remaining liquid in the other tips becomes dead volume. Integra has developed a reservoir combined with two innovations: unique surface treatment and the SureFloTM anti-sealing array to combat this problem.

SureFlo uses a simple but compelling principle. The pipette tip can sit at the bottom of the reservoir without sealing or creating a vacuum because of a series of tiny channels. This allows the reagent liquid to flow smoothly. The specially formulated hydrophilic, inert surface treatment enhances this system by preventing liquid from pooling. This results in a reservoir specifically created to offer the lowest dead volumes available.

A Divided Reservoir with all the Benefits

Our most recent release is the divided reservoir. This offers 5 and 10 ml volumes next to each other whilst still comfortably fitting in a 25 ml reusable base. Volume graduations are clearly visible which allows for accurate filling.

Early tests revealed that dead volumes of less than 3 µl can be achieved even on the 5 ml side. This is the lowest ever. This new design enhances INTEGRA’s complete range of VIAFLO pipettes, VOYAGER adjustable spacing pipettes and multichannel EVOLVE manual pipettes. The eight-channel VOYAGER pipette is perfect for aspirating from the 5 ml side and then dispensing into either a 96- or a 384- well plate.

Pour-back spouts are moulded into the corners, as with other reservoirs in the range, which facilitate convenient and spill-free return of unused reagent to the source container. The new reservoir is compatible with a wide range of chemicals as it is available in both polystyrene and polypropylene.
