ActionsLiquid 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!

Excel™ Single- and Multi-channel Electronic Pipettors
- Exceptional Accuracy and Precision
- Simple, Precise Vol Setting
- Fully Motorized Piston Drive
- Multifunctional with Six Operational Modes
- Virtually Eliminates Pipetting Force
- 1-year warranty
Excel™ Electronic Pipettes are multifunctional units with operational modes for standard and reverse pipetting as well as multiple and sequential pipetting, mixing of samples, and serial dilutions. All functions are easily programmed with one hand on the well-positioned display and keypad. A fully motorized piston drive and auto-calibration guarantee excellent accuracy and reproducibility. A removable, rechargeable lithium-ion battery ensures many hours of performance between charges.
The body of the pipette has been designed to fit comfortably in the right or left hand. Along with being lightweight, the unit is also well-balanced. The plunger button, located on the back side of the instrument, requires just a small movement of the index finger to activate, reducing the risk of Repetitive Strain Injuries (RSI). The tip ejector slides easily with slight pressure from the thumb.
A small, rechargeable, lithium-ion battery powers the Excel™. A complete charge is achieved in just eight hours and last for 2,000 pipetting cycles. To ensure that a fresh battery is always available, a stand-alone charger and extra batteries are available. Also available is a 3-position linear stand for up to three single or multichannel pipettes and a carousel stand for up to six single or multichannel pipettes.

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.
Divided reservoirs from MIDSCI give you the option to customize your usage.
HS20821A:
Polypropylene solution basin/reagent reservoir has a standard 50mL basin on one side and 12 individual 5mL basins on the other side. Wells are angled both downward and outward, guiding multichannel pipettor tips toward a centered position, which helps to avoid contamination and waste. Blue indexing keeps samples oriented correctly; loose-fitting lids prevent evaporation and contamination. Non-sterile. Pack of 25 basins and 25 lids.
REBP-2000:
- 100% biodegradable, eco-friendly
- Trough within a trough design maximizes sample recovery
- Pour spout corners
- Graduations on inside wells
