Machines and Colloid Mills for Manufacturing Crop Protection Products

Probst & Class develop and manufacture colloid mills for the production of crop protection products.

Every end product needs its own bespoke machine configuration.

Our strategy for perfect customisation: puclab.

puclab – Pilot

Make an appointment for preliminary tests in our pilot plant.

We give you and your product as much time as needed. Together with your technicians/engineers, we determine the best possible configuration for your new PUC machine in our test lab and plan its integration into your process.

Efficient cost-effective solutions for agrochemical production

The formulation technology behind today’s crop protection products demands exacting manufacturing processes. Whether the goal is an emulsifiable concentrate (EC), a suspension concentrate (SC) or a multiphase suspension-in-emulsion system (SE), efficacy, storage stability and safety in use all hinge on precise process controls and uniform product quality. PUC colloid mills deliver the ideal conditions for producing high-performance agrochemical formulations.

Decades of experience in modular machine design—paired with the process know-how of our technicians and engineers—enable our equipment to cover virtually every formulation, process and application, from laboratory scale right through to full-scale production.

The following pages illustrate how PUC colloid mills are used to manufacture insecticides, herbicides and fungicides, and spell out the specific advantages they bring. Simply follow the links below:

Probst & Class as a Supplier to the Chemical Industry

Probst & Class mills are "state-of-the-art" machines that have been used in the chemical industry for 80 years. Using a PUC, both small outfits and large industrial companies produce crop protection products of consistently highest quality.

The high manufacturing quality of PUC machines typically ensures a service life of several decades. The supply of replacement and spare parts, even for very early models, guarantees a secure investment and low total cost of ownership over the entire life cycle of the machines.

Find your ideal machine, reliably and quickly

In the almost 100-year history of Probst & Class, there is one constant: Practically every end product needs its own individual machine configuration!

Two special features of Probst & Class guarantee the highest satisfaction and loyalty of our customers: The simple convertibility of our machines and our approach to customisation.

What has been part of our success for decades is now a strategy. We call this strategy puclab.
