SiriusT3 PhysChem Compound Screening Instrument

SiriusT3 is the only fully automated instrument designed for compound screening and lead optimization by investigating the physicochemical properties of a sample in vitro.

· Requiring only sub-milligram sample quantities in most cases, the SiriusT3 can complete the analysis in less than 6 minutes per titration using the high throughput pKa screening.
· Determine pKa values using two techniques: spectrometric (for UV-active compounds) and potentiometric (for non-UV active compounds).With high throughput automated screening capabilities, SiriusT3 can complete up to 80 assays a day.‍
· Measure log P/D as a function of pH in less than 2 hours using the potentiometric technique in place of traditional shake-flask methods. Determine kinetic and intrinsic solubility using the patented CheqSol technique within two hours.
· Use the CheqSol technique to provide intrinsic solubility as a function of pH and generate detailed information about the extent and duration of the supersaturated states.

Use the SiriusT3 in the format that works in your lab by choosing one of four different configurations‍
· DTAu –Fully automated with pKa high throughput screening SiriusT3 system with both spectroscopic and potentiometric assay capabilities.
· DTu – A single vial system for one assay at a time with both spectroscopic and potentiometric assay capabilities.
· DTA – A fully automated system with only potentiometric assay capabilities.
· Lite - A single vial system for one assay at a time with only potentiometric assay capabilities.
