Brookhaven Instruments BioDLS



The BioDLS allows automatic particle sizing using industry–standard well plates. The precision controlled sample transfer mechanism allows the user to select any arbitrary well to initiate the experiment, as little as 2 uL sample volume is required for a measurement, and allows recovery of the transferred sample. Samples can be stored in up to two 384-well plates in an independently temperature-controlled compartment, and up to 768 samples can be transferred automatically to the flow cell without user intervention. The measuring cell has independent temperature control, allowing thermal studies related to stability and aggregation on individual samples. These features, coupled with the high-throughput fluid handling, allow the sensitivity, precision, and accuracy required for biotechnology and pharmaceutical research on proteins, peptides, viruses and antibodies.

Benefits Include:
  • Automate experiments and obtain results rapidly
  • Conserves precious samples
  • Perform experiments with no consumable costs
  • Detect aggregation at its onset
  • Analyze samples without dilution
  • Use without chemical modification of substrates
  • Minimize toxic chemical exposure with robotics
  • Interpret data using established theory
