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 Wheaton OmniSpense ELITE and UniSpense PRO are intelligent peristaltic pumps for all your dispensing needs. Whether you are making sterile liquid trasnfers to and from containers or filling vials or titer plates, these pumps will simplify and accelerate your laboratory output.

The systems are operated via a large 5" backlit liquid crystal display and chemical resistant keypad. Options are displayed as large icons for quick operation and easy recognition in national and international markets. The pumps also feature a small footprint and an angled polarized display perfect for use under a fume hood or biological safety cabinet.

Calibration of the units is simplified to a single intuitive calibration screen that walks the user through the process stepwise. This eliminates scrolling through menus and complicated instruction manuals.

The OmniSpense ELITE and UniSpense PRO can be specifically outfitted and programmed for your process. These programs can be saved and recalled at a later time for a quick application turnaround. Both pumps support tubing with different specificaitons and the OmniSpense ELITE can use stacked pump heads or microcassette heads for multiple small volume dosing.

The UniSpense PRO is a dual-speed dedicated dispensing pump designed to accommodate single of multiple filling applications. The OmniSpense ELITE is a variable speed dispensing pump with built-in FLOW mode. The FLOW mode allows for real time tracking of a single liquid transfer. The pump can be paused and restarted for more involved processes.

The OmniSpense ELITE and UniSpense PRO help menus are English, Chinese, French, Japanese, Korean and Spanish language enabled. These menus ensure the icon driven display is easily understood by national and international laboratories.

The OmniSpense ELITE and UniSpense PRO are ideal for any laboratory or clinical setting where accurate and precise dispensing is important.
