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!

Texan Reagent Reservoirs

 
  • Improved design
  • Vol graduations to 150 mL
  • a reinforced base that won't wobble on the counter, preventing spills
  • a new easy-to-open latch that can be manipulated with one hand
  • greater clarity for improved visibility of contents
  • manufactured by Excel Scientific

Texan reagent reservoirs are reusable -- an environmentally sound alternative to disposable reagent reservoirs. Their extra-large capacity means fewer refills and time saved. The V-shaped basin is compatible with both eight- and twelve-place multiple pipettors with minimal reagent waste. Lids are removable -- attached with ball and socket hinges -- and latch tightly for secure storage of left-over reagents. With lids closed, Texan reagent reservoirs are stackable. A perimeter ridge on the lid prevents sliding. Construction is clear, chemical-resistant, autoclavable polypropylene. Molded graduation marks provide Vol indication at 25, 50, 75, 100, 125, and 150 mL.


Available sterile and non-sterile. Sterile reagent reservoirs are supplied in bags of 5, nonsterile in bags of 10, both within outer packages of 100.

Aspirating Pipets

  • Ideal for aspiration of media and sample waste removal
  • Supplied without graduations or plugs
Item#:
ASPIPETSASP

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.

Features of Wheaton Pumps include:

  • Icon Driven User Interface
  • Trouble-Free Calibration
  • Ultra-High Precision Stepper Motor
