Lab Rotary coater (10cm stator drum)

This is the smallest of our rotary coaters. It comes in its own carry case and small air pump and is easy to set up in any lab or work area. With only a 10cm diameter stator drum one is able to coat single seeds (large seeded vegetables or agronomical crops) making this coater ideal for the coating of breeder seed samples. We have mounted a shoot and special packet clip for easy packing of the coated seed samples without the need to handle the seed. With the timer, it is easy to standardize the coating process. As it is a small coater it does not include a liquid dispensing unit or spinning disk (it is however optional) and the coating needs to be applied manually by pipet or syringe onto the rotating seed bed. 

This equipment is only suited to film-coat seed and can not be used for any powder coating.   

Rotary seed treatment and coating equipment

10cm Stator (drum)


  • Seed treatment
  • Film Coating


  • Research samples
  • Trial seed samples
  • Ability to duplicate production scale treatments

Example capacity for seed treatment/coating (capacity for selected crops) depending upon seed density:

  • Broadacre crops = 5g up to 100g per batch
  • Horticulture crops = 5g up to 60g per batch




Commercial rotary batch machinery technology

Uniform and accurate seed treatment application on every sample

Ability to coat small sample batches for R&D, trial work and seed treatment recipe development

Quick and easy scale-up

Full set of controls for reproducing protocols

Greater efficiency and time-savings for large numbers of samples

Standard controls include variable rotor speed, manual on/off and discharge door unloading into empty seed packet holder.

Ease of use and full operator control
