The QHM-DS310 provides unmatched sample reproducibility with the highest sensitivity, innovative technology, and industry-proven reliability.
The QHM-DS310 and ITC Auto are designed for the most challenging life science laboratory environments that require high sensitivity, high productivity and the most advanced ITC technologies. The QHM-DS310, are used in gene therapy applications for characterizing serotype and drug loading in AAVs and LNPs, as well as target and off-target binding interactions. The QHM-DS310 brings advanced engineering to all critical aspects of the measurement ensuring the highest quality ITC data.
Features:
- AccuShot™ delivers the titrant to the right location for the best mixing
- FlexSpin™ provides innovative slow speed stirring, efficient mixing and highest sensitivity
- Fully automated, user-selectable system cleaning routines eliminate run-to-run contamination
- Intelligent Hardware Positioning for precise reliable injections
- Solid-state active heating and cooling for true isothermal temperature control
- Choice of standard volume (1.0 mL) or low volume cells (190 µL)
- Industry proven 96-well, temperature-controlled liquid handling autosampler. Autosampler can be included with initial purchase or added at a later date
- Powerful ITCRun and NanoAnalyze for the most comprehensive suite of tools for method optimization, model fitting, batch analysis, graphing and data export.
Quantithermal Instruments has perfected what others have attempted. The Affinity ITC is a powerful tool for measuring a wide variety of molecular interactions. It provides both inexperienced and advanced ITC users the highest confidence in generating superior ITC data.
