Divided Reagent Reservoirs Lowest Dead Volume On The Market!

Lowest Dead Volume On The Market!

Product story

Save On Precious Samples And Expensive Reagents!

Large reagent dead volume is a serious issue in laboratories, especially when pipetting precious liquids into well plates using a multichannel pipette. Traditional reservoirs have a V-shaped bottom to minimize dead volumes. However, as the liquid level lowers, the liquid pulls apart and starts to pool. As a result one or several tips on a multichannel pipette may aspirate air. The remaining liquid in the reservoir and the pipette tips is then considered dead volume.

To solve this, INTEGRA developed reservoirs with a SureFlo™ anti-sealing array on the bottom and a unique surface treatment. The anti-sealing pattern consists of a series of tiny channels that allow the liquid to flow evenly across the bottom of the reservoir and prevent pipette tips from sealing. Pooling of liquid is prevented by a specially formulated, hydrophilic surface treatment. Additionally, the reservoir is divided, offering 5 and 10 ml volume side by side, resulting in a reservoir with the lowest possible dead volume! 

How it Works

How it works

25 ml divided reservoirs are comprised of 5 and 10 ml compartments, while still nesting comfortably in the standard 25 ml reusable, sturdy base. Each reservoir features the SureFlo anti-sealing array and hydrophilic surface treatment providing especially low dead volumes. This is particularly helpful when pipetting precious samples or expensive reagents with a multichannel pipette. Inserts are available in polystyrene or polypropylene for improved chemical compatibility.

  • Divided reagent reservoir - lowest dead volume

    Lowest Dead Volume

    The SureFlo™ array located on the reservoir bottom prevents pipette tips from sealing off and stops liquid from ‘popping’ into tips, filters or even the pipette. The anti-sealing pattern consists of a series of tiny channels that allow the liquid to flow evenly across the bottom of the reservoir. An inert hydrophilic surface treatment prevents liquid from pooling. The result is the lowest dead volume regardless of the application. 

  • 8 channel VOYAGER tip spacing pipette in combination with divided reservoir

    Compatible With All INTEGRA Handheld Pipettes

    The divided reservoir is designed to be compatible with all VIAFLO fixed spacing and VOYAGER adjustable tip spacing multichannel pipettes. For example, the 12.5 and 125 µl 8 channel VOYAGER adjustable tip spacing pipette compressed to 4.5 mm spacing can access the 5 ml reservoir compartment and then expand to 9 mm spacing to access a 96 well plate.

  • Reusable divided reservoir base

    Toss The Insert And Keep The Base

    The sturdy reusable base features clearly printed volume graduations and holds disposable reservoir inserts securely during use. One free base is included with every case of bulk or individually wrapped reservoirs.

  • Divided reagent reservoir lids can also be used as lids

    Reservoirs Are Lids

    Each 25 ml base can accommodate two reservoirs; one acting as a lid to allow short term storage of reagent on a benchtop while preventing evaporation or contamination from particulates.

  • Divided reservoirs feature pour back spouts

    Pour Back Spouts

    To further reduce liquid waste, 25 ml divided reagent reservoirs feature pour back spouts molded into each corner. The pour back spouts control liquid flow and allow you to neatly and easily return excess fluid to a source container.

  • Divided reagent reservoirs come in compact, space-saving packages

    Innovative Packaging Options

    Designed to nest within one another without sticking, INTEGRA 25 ml divided reagent reservoirs come in compact, space-saving packaging. A perfect solution if bench space is limited or when working in a safety cabinet! Each case contains four sterile, stand-alone sleeves with 50 inserts.
