High-pressure lab equipment · in-house control system

300MPa experiments that still reproduce after 72 hours

The HPSTART25.4x4 ore-formation simulation press ships with a 25.4mm sample chamber and our in-house cold-seal integrated high-pressure high-temperature control system. Temperature control accuracy is ±0.1℃, and steady-state pressure stays within ±1MPa over long runs—so every replicate dataset from a rock-fluid reaction is traceable and reproducible.

PAIN POINTS

The equipment is rarely the problem. Reproducibility is.

For anyone running high-pressure rock-fluid experiments in geology and geochemistry, two things decide whether a study holds up: whether temperature and pressure stay stable for tens of hours, and whether replicate runs reproduce each other.

Temperature and pressure drift

Once temperature or pressure drifts, an entire multi-day dataset can be lost. The gap between rated accuracy and real long-run behaviour is where most research instruments fail.

Poor reproducibility

When reproducibility depends on operator experience and intuition, different researchers get results that disagree—and the error bars in the paper become a problem.

Low automation

Pressure hold, temperature soak and depressurisation all need someone watching. Night runs are the hardest to keep consistent, and accumulated system error quietly eats experimental accuracy.

APPLICATIONS

One platform, three core experiment types

A sealed high-pressure high-temperature platform for geological institutes and university geochemistry laboratories.

Rock ore-formation simulation

Reproduce mineral migration, transport and enrichment in rocks under high pressure and temperature to study ore-forming mechanisms.

High-pressure water-rock reaction

Study element migration, alteration and dissolution-precipitation kinetics in rock-fluid systems, with runs lasting tens of hours.

Hydrogen production via water-rock reaction

Run sealed rock-fluid hydrogen generation experiments for deep-crust, deep-sea and deep-space water-rock research and for energy exploration.

CONTROL SYSTEM

In-house cold-seal integrated control system

The entire system operates closed-loop, acquiring and adjusting pressure and temperature in real time. Custom multi-segment programme curves automate pressure hold, temperature soak and depressurisation, cutting the system error introduced by manual operation.

For research instruments, what matters is controllability and repeatability. You set the programme; the system does the rest.
