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!

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

Heathrow Scientific® Multi-Channel Reagent Reservoirs

 

Heathrow Scientific® Multi-Channel Reagent Reservoirs offer a versatile and contamination-reducing solution for multi-channel pipetting workflows. Featuring a dual-compartment design, this reservoir includes a single 50 mL basin on one side and twelve individual 5 mL slotted basins on the other—perfect for handling multiple reagents with minimal waste.

 

Each slotted well is numerically imprinted for easy sample identification, while angled basin walls guide pipette tips to the center, helping reduce cross-contamination and reagent loss. The included snap-on cover protects contents from evaporation and contamination during short-term storage or processing.

 

Made from white polypropylene, this disposable yet autoclavable reservoir is ideal for sterile environments. Sold in packs of 25, it’s a practical consumable for research, clinical, and industrial laboratories.

 

Key Features

  • Dual compartments:
    • One 50 mL basin
    • Twelve 5 mL individually numbered slotted wells
  • Angled wells reduce pipette tip waste and cross-contamination
  • Numerical imprinting for sample tracking
  • Protective cover is included to minimize evaporation and contamination
  • Made from durable white polypropylene
  • Autoclavable and disposable

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.
