NIR Lab Testing

In-house near-infrared spectroscopy and a full ISO-standard test suite — every latex batch verified before it ships.

Every batch is traceable through our Synchronised Traceability™ system — from smallholder plantation to your delivery point. Full FSC™ CoC documentation, full-spec quality verification, and EUDR-ready provenance data included.

Contact our team to discuss specifications, custom formulations, minimum order quantities, or to request a sample shipment.

Our laboratory is not a testing bench bolted onto the production line. It is the engine behind everything we ship — batch verification, specialty formulation, and a standard that holds year after year. The instruments themselves are not the advantage: near-infrared spectroscopy is available to any producer who buys it. The advantage is the discipline of using it well, batch after batch. Most producers test. We research.

What the lab does

Quality control. Every batch is tested for DRC, TSC, VFA, KOH, mechanical stability, coagulum, trace metals, and sludge content — the full suite of ISO-standard tests. NIR spectroscopy gives us rapid, non-destructive verification in minutes, without waiting on traditional lab methods.

R&D and formulation. Specialty blends start here — low-ammonia variants, modified viscosity grades, and application-specific compounds developed to a customer’s exact requirements.

Consistency. The lab is where a steady record is kept: the same specification, batch to batch, with the documentation to prove it.

Equipment and capability

  • 120 GEA centrifugal separators — the industry standard for latex concentration, at a scale that holds quality steady across high-volume production.
  • NIR spectroscopy — near-infrared verification of every batch before it ships: non-destructive, rapid, and precise.
  • Full ISO-standard test suite — mechanical stability, coagulum, trace metals, sludge, volatile fatty acids, and KOH number, run on every batch.
  • ISO 9001 / ISO 14001 laboratory — every test documented and traceable, with full audit trails available to buyers who need them.

The quality-control process

  1. Raw-material inspection — field latex is assessed on arrival and its batch identity verified against our Synchronised Traceability™ system.
  2. Centrifugal separation — concentration on GEA equipment held to precise temperature and pressure profiles, optimising DRC without compromising stability.
  3. NIR verification — before release, NIR confirms DRC, TSC, and alkalinity are within spec. Minutes, not hours.
  4. Full lab testing — the complete ISO-standard suite, with every result logged to the batch record.
  5. Traceability and release — results are written into the traceability system; stock is held in climate-controlled tanks and released only when every criterion is met.
  6. Shipment and tracking — each shipment is tracked end to end, and the customer receives batch documentation with the full chain from plantation to delivery.

Advancing the work

The lab does not only test — it develops. We work on specialty formulations for medical, industrial, and consumer applications; on process improvements that cut energy use, reduce waste, and lift yield; and we collaborate with academic and industry partners to advance sustainable latex science.

Buyers are welcome to see it first-hand. We host site visits for procurement and quality teams — the clearest way to understand how the material you rely on is actually made.
