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!

Robotic Tips for Tecan - Conductive, Boxed

Black, sterile, RNase and DNase free polypropylene pipette tips made from medical grade conductive materials which are compatible with the TECAN EVO Freedom and other TECAN robotic liquid handling robots.
These NEST Scientific conductive tips for TECAN robotic systems come pre-loaded in sturdy boxed racks of 96 tips. 

Sold in cases of 4800 tips or 50 racks of 96 tips. 
NEST Scientific is a recognized leader in high quality manufacturing of critical laboratory plastics. 

NEST Scientific TECAN tips offer these quality assurances:

  • Tips are packed in separate cavities with uniform conductivity: tips of each box share the same cavity number to ensure the product traceability and the conductivity uniformity and to improve the accuracy of experimental results, greatly reducing the difference between individual products.

  • Smooth inner surface: the unique process technology ensures that the tips have smooth inner surfaces, therefore greatly reducing the amount of residual liquid.

  • Super hydrophobicity: the porous tissue filtration by filter tip ensures optimum performance and the super hydrophobicity of the tip forms a strong barrier against aerosols and eliminates the risk of sample cross-contamination.

  • Good air tightness and adaptability: the structure mapping is conducted per the original adapter and the proven injection-molding ensures that the products have good air tightness and adaptability, improving the mechanical precision of the products during work.

  • Strict quality management and control test: Effective quality inspections are conducted for strict quality management and control per the client’s needs, including tests for DNA, RNA, proteases and pyrogens.

  • Air tightness test: precise equipment are used to test the air tightness between the tip and the adapter, to ensure good air tightness for each batch of products.

  • Tests for resistance and CV values: a certain number of products are sampled for each batch for inspection, which is conducted using precise and unique measuring tools to ensure the accuracy and reliability of the test results to ensure the uniform conductivity of products.

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.

MULTI-CHANNEL PIPETTE 8- AND 12-CHANNEL

CappAero multichannel pipettes have a unique construction, ensuring extremely easy tip mounting and ejection. Both the 8- and 12-channel pipettes have an external ejection lever, assuring ergonomic and effortless tip ejection. This unique construction enables the thumb to rest under tip ejection and helps to activate the other fingers, considerably reducing the thumb workload. Apart from the external ejection lever, the lower part of each 12- and 8-channel pipette is slightly bent in order to eject only 2 tips at a time! This happens smoothly, as if all 8 or 12 tips were ejected in one take, but this special construction of the lower part distributes the pressure and minimizes the workload. Each tip cone of Capp multichannel pipettes is made of anodized aluminum and has double O-rings, which all together eliminate the need to 'hammer' the pipette into the tips rack to secure the optimal tip mounting.

CappAero multichannel pipettes guarantee single channel accuracy and precision across all channels due to the special design and construction of the Capp piston assembly. Capp 8- and 12-channel pipettes are incredibly robust and fully autoclavable, offering easy maintenance. The use of anodized aluminum and metal nose cones instead of plastic ones substantially reduces risk of breakage due to accidental dropping and tip mounting. The lightweight metal components and stainless steel pistons ensure a highly robust performance for ultimate stability over time in terms of accuracy and precision. This smart and highly ergonomic multichannel pipette is built to last!

 

  • Easy and light tip mounting and ejection
  • Guaranteed single channel accuracy and precision
  • Fully autoclavable pipette body
  • Anodized aluminum and metal nose cones
