Faster starts

Speed starts before dispatch.

Scope the work before the bottle moves, so time is not lost deciding methods after arrival. We confirm the tests, sample requirements, receiving details and quoted timing before collection.

  • Test panelMatched to the fluid and question
  • Sample requirementsContainer, volume and handling
  • Receiving routeLocation and dispatch instructions
  • Quoted timingAgreed before the sample moves

From sample to operating decision.

A result is useful only when it stays connected to the fluid, asset, sample point, operating state and baseline.

See how we protect quality
  1. Brief

    Name the fluid, asset, sample point and question that needs an answer.

  2. Collect

    Use the agreed container, volume and collection instructions.

  3. Test

    Apply methods and quality checks suited to the actual fluid.

  4. Review

    Compare the results with baselines, history and operating context.

  5. Decide

    Make the finding, uncertainty and recommended next step clear.

Four fluid systems, one brief

Coolants, dielectric fluids and oils in one testing brief.

Coordinate cooling, power and mechanical samples without forcing different fluids into the same test panel or acceptance limits.

A better model for fluid testing

Faster service. AI-enabled chemists. Clearer decisions.

Faster service starts with fewer manual handoffs. Our direction is AI assistance that helps chemists organize evidence, compare history and focus their review. Laboratory results should connect with available operating and sensor context, with a human reviewer accountable for the interpretation and next step.

  • Reduce avoidable intake and reporting handoffs
  • Support chemists with traceable AI assistance
  • Connect laboratory, sensor and maintenance evidence
  • Explain the next step, not just the result

PG25 technical focus

25% glycol does not define fluid condition.

A useful PG25 assessment begins with the exact product, concentration basis, inhibitor chemistry, wetted materials and applicable OEM limits. Only then can chemistry, contamination and metals be interpreted together.

How we assess PG25Representative methods
Five parts of the assessment
Condition areaRepresentative method
Identity + concentrationRefractometry and matched-reference FTIR
D3321 / E1252
ChemistrypH, reserve alkalinity and product-specific UV-Vis indicators
D1287 / D1121 / validated assay
Ions + degradationChloride, sulfate and selected degradation markers
D5827 / validated route
Wetted materialsElements selected from the verified system materials

CleanlinessAppearance, sediment and particle context where the route is suitable
Method confirmed by fluid

Method applicability and acceptance criteria are confirmed for the named fluid and system. Generic limits are not substituted for product or manufacturer guidance.
