RheoSense, Inc.

Chip-based viscometers and rheometers for biotech

Overview

RheoSense makes precision viscometers and rheometers using Viscometer/Rheometer-on-a-Chip (VROC) technology with MEMS and microfluidics, designed to work with very small sample volumes in biotechnology and pharmaceutical work. The m-VROC and microVISC devices place sensing elements and microfluidic channels on a chip to measure viscosity and viscoelastic properties from tiny samples, delivering readings through a compact, user-friendly interface. They stand out from competitors with patented on-chip VROC technology and advanced microfabrication that enable the smallest sample volumes alongside high accuracy and easy operation, already used by Fortune Global 500 firms and leading universities. The goal is to make viscometry faster and more cost-effective by providing precise, low-volume measurements for biotech, pharmaceutical, and protein therapeutics applications.

Simplify's Take

What believers are saying

  • Small-sample viscosity testing fits biologics, formulation, and other scarce-sample workflows.
  • High-throughput screening shortens candidate selection in drug discovery and development.
  • Chip cleaning automation supports reuse, lower downtime, and recurring maintenance revenue.

What critics are saying

  • microVISC PRO offers portable screening with 100 µL samples and no software requirement.
  • Strict pipetting, centrifugation, and bubble-control steps raise adoption friction and operator dependence.
  • Proprietary software and chip-cleaning workflows can trigger switching if customers standardize elsewhere.

What makes RheoSense, Inc. unique

  • VROC initium one plus runs 96 samples in 24 hours with 19 µL inputs.
  • m-VROC II measures viscosity from samples as small as 15 µL.
  • Clariti software supports automated loading, analysis, filtering, and data export workflows.
