TTP Labtech has developed a bulk dispenser to extend the capabilities of Mosquito, its automated nanoliter liquid handler. The new add-on head provides bulk reagent dispensing from eight independent channels to offer assay miniaturization through precise pipetting of compounds in up to 384-well microplates. With its disposable, positive displacement pipettes that ensure zero cross-contamination and low dead volumes, the bulk dispenser transforms the capabilities of the instruments nanoliter liquid handling into a highly flexible system for high throughput screening laboratories. The bulk dispense head attaches directly to the liquid handlers HTS pipetting head and dispenses liquid from a flask/tube/bottle to part, or whole plates on the plate deck.
