A Different Design for each Specific Application
Tomtec's Quadra 3® is a different design concept for liquid handling than our competitors. The primary concept is to do more in less benchtop space. While a large flat bed pipettor has several stations, how do the microplates to be processed infeed and outfeed - manually?
The pipettor is serviced by a 6-station shuttle which carries resources to the pipettor for processing. The shuttle is served by four (4) cassette stackers. Each cassette stacker holds twenty-five (25) microplates, that can be twinned to handle fifty (50). The cassette stackers are interchangeable between other Tomtec products (i.e. plate washer, incubator, plate reading, plate sealing, etc.). Microplates no longer have to be handled individually. They can be moved efficiently through the entire processing protocol by use of cassette stackers. The stackers are pneumatically operated to provide the force necessary for reliable operation. They have the ability to re-stack which means they can also sort. In addition to all types of microplates, the stackers can also place specific reservoirs on the shuttle as the program requires.
The stage automatically lifts plates and reservoirs from the shuttle to the pipettor. The height is precisely controlled to facilitate touching off sub-microliter aliquots. The stage is also used to load tips safely, for both personnel and equipment. The stage cannot get to full force until the tips are in safe contact with the pipettor head, otherwise it is limited to about 10 pounds of force. A full indexing stage is available to reformat from 96 to 384 to 1536 or any other matrix. When used with a single row of tips it can complete serial dilution testing in either the 8 or 12 direction or both, for synergy studies.
Enhance with Specific Application Accessories
The value of the Quadra 3® product line is augmented with application specific accessories that are program controlled. Custom made reservoirs provide less than full plate pipetting. They are used to add Standards & Controls to the plate matrix. Serpentine reservoirs minimize dead volume. Circulated reservoirs provide continuous operation. A special live bottom reservoir is designed to keep particulate matter in suspension (i.e. magnetic beads), various vacuum boxes are available, including a fully automated version to meet the requirements of various filtration protocols. Shaking nests and temperature- controlled nests are also available.
