Nanomechanical infrared analyzer

The TA Instruments/Waters Powder Rheology Accessory extends the Discovery Hybrid Rheometer to characterize powder behavior during storage, handling, processing, and use. Quantitative dynamic flow and shear measurements—under ambient or controlled temperature—accelerate development, optimize processes, screen materials, and reveal powder morphology differences to prevent scale‑up issues.

Countable PCR is the only PCR-based method that directly counts your targets, giving you unprecedented and highly sensitive insights into your samples. Don't be limited by qPCR, dPCR, or even NGS. Find even the rarest targets when you experience single-molecule precision and ultra-high sensitivity in a familiar PCR workflow. Plus – quickly develop a new multiplex assay in 3 days.
