Instrumentation for High-Throughput Analysis and Drug Screening

All facility instruments are compatible with 96-well and 384-well microplates. It may be possible to use other plate types for select instruments.

Biotek Multiflo Microplate Dispenser

The Biotek Multiflo is configured with two peristaltic cassette dispensers, and two syringe dispensers, allowing at least 4 reagents to be dispensed simultaneously. A single reagent can be dispensed with each syring pump and up to 8 reagents (one per plate row) can be dispensed using the peristaltic pump cassettes. The Multiflo is equipped with a Biostak multiplate stacker.
2 syringe pumps                   1-3000 ul
2 peristaltic cassettes          1-3000 ul
Plate type                             96 and 384 well
Capacity                               30 plates

Agilent Bravo Automated Liquid-Handling Platform

The Agilent Bravo is a versatile, high-precision liquid-handling system that enables plate-to-plate liquid transfers, among other tasks. It is equipped with 96ST head, allowing for the use of disposable pipette tips, and a tip-washing station, allowing the cost-saving reuse of pipette tips. It can process batches of up to 4 plates, although batches of 8 or 12 plates may be possible with certain procedures.
Volume range                  0.3–70 ul
Plate type                        96 and 384 well
Capacity                          4 plates

Molecular Devices SpectraMax M5 Multi-Mode Plate Reader

The SpectraMax M5 is a multi-mode plate reader equipped with the StakMax plate stacker that can accomodate 50 plates. It allows for both top-and bottom- read modes.
