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!
Low Retention Filter Pipette Tips
CELLTREAT Pipette Tips deliver high performance with exceptional value. A perfected balance between raw materials and efficient manufacturing process results in superior low retention. With a universal fit they are compatible with major pipettes. Smooth, hydrophobic surfaces ensure accurate pipetting.
Filters reduce cross contamination and prevent damaging aerosols from penetrating into the pipette and are positioned to allow extra headspace when pipetting maximum volume.
Multiple sizes are available, including extended length tips (10 µL and 100 µL) to allow better access to the bottom of test tubes, reagent bottles, flasks, and other vessels. The 200 µL filter tip is longer than standard tips for better access to vessels and increased headspace to filter. Molded volume reference markings offer a quick double check opportunity.
Pipette Tip Racks
- Hinged Lids are designed for easy one-handed opening, making it easier to access repeatedly
- Lids have a stacking feature for added stability and a secure locking tab
- Interior support ribs prevent rack from warping

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.
