Tomtec - Model Quadra4 -Automated Liquid Handling

An important patented feature of our air displacement pipettor heads is the ability to blow low air pressure through the tip orifice under program control.  We refer to it as a "Timed Dispense."

With the Timed Dispense function you clear the tips contents without touching the liquid in the plate.  This function allows you to add the same reagent to multiple plates on the shuttle without contaminating the tips.

The Timed Dispense function is of extreme importance if you are pipetting both aqueous and organics.  You can clear the organic vapors with a timed dispense function, and then pipette aqueous accurately.  Competitive designs must stop and change tips when going from organic to aqueous pipetting.

The Quadra4 operates through an intuitive and flexible Graphical User Interface on top of a Windows OS.  Simple and easy to learn, the Q4 software allows users to quickly program their protocols, increasing day to day productivity.

For over 40 years Tomtec has assisted the scientific communities research with the incredible accuracy of our Quadra4 pipetting heads.  Our air displacement, positive displacement, and time/pressure heads will give users the most precise results for even the most complicated of laboratory protocols.  Click to view a sample of our Accuracy Reports and Performance Qualifications.

Laboratories operating under the standards of Good Laboratory Practices (GLP), as defined by Section 40 of the Code of Federal Regulations Sections, 160 and 792, requires that all equipment used for the generation, measurement, or assessment of data shall be adequately tested, calibrated, and/or standardized, and that written records are maintained for such compliance.

In conjunction with providing our normal service and preventive maintenance programs, we also offer an opportunity to receive as requested a factory replacement head which certifies that the head is working within factory specifications. A continuing recurring program can be set-up to meet your specific needs based on your usage discounted accordingly for frequency.  Proper documentation will be provided to meet the GLP requirements.

Each Quadra4 system is custom crafted in our Connecticut facility, to your exact needs. Our field engineers work with your research team to understand your work-flows and expectations, and then recommend the best possible solution at the best possible price. Once your new unit is received, our engineers come back and install, test and train your team on how to get the most value from your Tomtec investment.  With both air displacement pipetting or positive displacement design available, in conjunction with an indexing microplate stage, the Quadra4 allows the support of complex pipette work-loads found on workstations that cost five-times its price.  In addition, the optional automated plate stacker`s provide true walk away assay automation.  The following list provides an overview of capabilities and features.
