Seed quality is proven in the laboratory

Seed certification and quality control follow a familiar routine: a submitted lot is divided into representative working samples, pure seed is separated from inert matter and weed seed, seed is counted for germination tests and thousand-seed weight, moisture content is measured, and X-ray imaging shows the internal condition of the seed. Official seed testing stations, agriculture authorities, gene banks, breeding programmes, seed companies and universities rely on these instruments to verify seed lots before they are traded, stored or sown. In Saudi Arabia, where food security is a national priority under Vision 2030, dependable seed testing protects both growers and the wider supply chain. EnmaTech supplies, installs and supports seed laboratory equipment and helps plan complete seed testing laboratories.

Representative sampling

Centrifugal, Boerner and riffle dividers reduce a large submitted sample to a working sample without bias, the starting point of every dependable seed test.

Purity and contamination checks

Illuminated and polarised-light purity benches, seed blowers and sieves help analysts separate pure seed, other crop seed, weed seed and inert matter accurately and consistently.

Faster counting and planting

Automatic and vacuum seed counters prepare germination replicates and thousand-seed weight samples in minutes, cutting manual counting errors and analyst workload.

Seeing inside the seed

Agricultural X-ray imaging reveals empty, cracked, insect-damaged or poorly filled seed without destroying it, guiding decisions on valuable breeding and conservation lots.

Frequently Asked Questions

What equipment does a basic seed testing laboratory need?

A typical starting set includes a sample divider, purity workbench, test sieves, seed counter, moisture meter, balance and germination incubator. X-ray imaging and seed blowers can be added as sample numbers and seed species increase.

What can a seed X-ray system show?

It reveals the internal structure of each seed, so analysts can check whether the embryo and storage tissue are fully developed and spot cracks, hollow seed or insect damage before germination testing or storage.

Why are several types of seed divider offered?

Each type suits different seeds and laboratory routines. Riffle and Boerner dividers are robust and need no power, while centrifugal dividers work fast with free-flowing seed. Many laboratories keep more than one type.
