Liquid Handling

MIDSCI has a full line of liquid handling products including laboratory pipettes, pipette tips, pipettors, reagent reservoirs, aspiration systems, and pipette controllers.

Some liquid handling products are known to have safety issues and others are prone to errors that lead to poor results. 
  
Our liquid handling products keep in mind the basics, like price and quality, but also go one step further to solve or pre-empt these and other issues researchers (and even the planet) may face. 
  
For instance, the aspiration systems we stock are known for performance but also for safety. Our pipettor calibration service ensures reproducible results. We carry unbreakable transfer pipettes that avoid glass hazards. And we even have eco-friendly reagent reservoirs!

The Harvest 25mL ASPIR-8 Reservoir features tighter dimensions which make it the ideal reservoir for 8-channel pipettes. The 75mm width of the ASPIR-8 is specially designed to minimize reagent exposure and usage when an 8-channel pipette is used as opposed to the typical design for 12-channel pipettes.

Features:

  • Shorter size - conserves valuable reagents
  • Designed for 8-channel pipettes
  • RNase, DNase, & Pyrogen-free
  • Corner "bump-outs" prevent units from sticking together

Dispensette® S bottletop dispensers build on the 50 year history of BRAND® dispensing expertise. Continual upgrades makes this the safest and most convenient ever, while retaining the features making the Dispensette® the world's favorite bottletop dispenser. The "floating piston" design of the Dispensette® S forms a zero-wear sealing system with outstanding sliding properties. Optimized flow channels make dispensing and priming even easier- particularly in instruments with large volumes.

The Dispensette® S bottletop dispenser is supplied with: discharge tube, valve mounting/calibration tool, polypropylene adapters, telescoping filling tube, recirculation tube (optional), performance certificate, operating manual, and one year warranty.

The Dispensette® S Organic has much in common with a Dispensette® S, however there are two major differences. The Dispensette® S Organic has a glass piston, rather than a PFA-coated piston. This optimizes it for use with concentrated acids and organic solvents that can interact with the PFA, but makes it less useful for bases. In addition, the valve spring in the Dispensette® S Organic is tantalum (vs. platinum-iridium alloy) allowing it to be used with peroxides, again, at the expense of compatibility with bases. Because of the different construction and chemical compatibility, parts from a Dispensette® S should not be used with a Dispensette® S Organic, and vice versa.
