VistaLab Reagent Reservoirs, Bulk

 

Reservoirs have multiple features to help to limit “dead volume” or leftover residual liquid. This superior low retention maximizes reagent recovery up to 67% better than comparable reservoirs.

 

The trough-within-a-trough design funnels remaining liquid into a secondary deep channel, so leftover drops can be easily aspirated, preventing reagent waste. The secondary trough also helps improve pipetting consistency, ensuring every channel of a multi-channel pipette can draw up equal volumes.

 

Additionally, these reservoirs have a proprietary high-wettability, hydrophilic surface treatment that helps lower surface tension, causing liquid to spread rather than bead up. This assists in the prevention of water droplets clinging to walls.

 

VistaLab reservoirs are ergonomic and easy to use with molded graduations, pour spouts at every corner, and a wide base for better stability. 100 mL options are compatible with VistaLab 100 mL Reagent Reservoir Coolers and either come with lids or have lids that may be purchased separately.

Green Reagent Reservoirs

Innovative Design Saves Space and Reduces Plastic Waste

 

The "Green" Reagent Reservoirs incorporate several innovative design features that reduce plastic waste, save storage space, and enhance performance. This reagent reservoir system consists of disposable, clear polystyrene inserts that fit within a rigid base. Because the skirt on the inserts has been eliminated, this significantly reduces the amount of plastic waste that is experienced when using standard one-piece reagent reservoirs.

 

  • Innovative design that reduces plastic waste and saves space
  • Saves 75% in storage space
  • Easy-to-see, bold, black Vol graduations eliminate costly overpours
  • Pour-spout corners provide easy, spill-free pouring
  • Unique trough within a trough design for complete sample retrieval
  • 2nd reservoir can act as a lid to prevent evaporation and contamination
