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!

Labmax™ Bottle Top Dispensers

  • Unique closed circuit air purging system
  • Reagent "guard valve" for safety shut down
  • Exclusive integrated swivel neck
  • Patented direct displacement PTFE piston
  • Quick and accurate volume adjustment
  • Auto - calibrating
  • Fully autoclavable
  • ISO 9001 certified


The Labmax™ bottle top dispenser has been developed through extensive testing and input from end users. The result is an easy to use system with a variety of important features.


Spill Prevention Feature

The unique closed circuit air purging system allows air and bubbles to be eliminated from the dispenser without loss of valuable reagent. The reagent "guard valve" prevents accidental discharge of reagent when the dispenser is not in use. A simple turn of the operations mode selector activates this safety feature. Eliminating the need for discharge tube caps. The exclusive Integrated Swivel Neck allows the discharge tube to be turned 360° for convenient dispensing without affecting the connection to the bottle.

 

Locking Rocker Switch

The Dispensers are fully autoclavable to 121°C for sterilization. The Labmax™ can be disassembled quickly and easily for thorough cleaning. Quick and accurate volume adjustment is easy with the locking rocker switch. The zero point is manufactured into the Labmax™; calibration is not necessary, even after disassembly and cleaning. ISO 9001 Certification has been achieved in the design, development and manufacturing stages of the Labmax™. All Labmax™ dispensers feature a dated mark for compliance with ISO 9001 procedures.

Dispensette S Trace Analysis Bottle Top Dispensers

  • Simple to mount discharge tube available with or without integrated recirculation valve
  • Designed without additional sealing rings for ease of cleaning and maintenance
  • Replaceable discharge valve with safety valve
  • Olive-shaped filling valve for firmer attachment of filling tubes
  • Improved flow technology results in faster priming
  • Scalloped track for secure volume setting on analog dispensers

The Dispensette® S Trace Analysis is the next generation bottletop dispenser for precise volume dispensing of high-purity media for trace analysis. It is especially suited for dispensing acids, bases and hydrogen peroxide in the volume range from 1 to 10 mL. The components of the fluid path have been selected to only contain the highest purity materials, such as fluoroplastics and sapphire. The result is a trace metal content of dispensed liquid generally in the low ppb range, or even in the low ppt range, depending on the application. Both platinum-iridium and tantalum valve springs are available for application compatibility.

Reagent Reservoirs
 
Multi-channel solution reservoirs are designed for use with all multichannel pipettes. Standard 4 channel, 8 channel, 12 channel and various special purpose pipettes are all compatible with these disposable, polystyrene reservoirs. To facilitate easy, dripless pour-off of unused reagents and solutions, all versions have indented "spouts" in each corner. Bottoms are formed with a sharply tapered "V" shape to minimize waste and reagent consumption.
 
Whether your application calls for bulk packaging, packs of 5, or individually wrapped reservoirs, MIDSCI reservoirs are supplied sterile and are packed in environmentally friendly packaging, within biodegradable bags and recycled cardboard boxes.

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.
