Versatile Cutting Mill Optimised for Cannabis Processing
Just because it’s white doesn’t mean
it’s whiter than white
A rose by any other name should be treated with equal caution – a point that certainly applies to microplates.
The thorny issue is that the production of polypropylene microplates can involve the use of contaminants, such as plasticizers or mould release agents, which may subsequently affect the accuracy of assay results. This is especially so if you use powerful solvents, such as Ethyl Acetate or DMSO.
Microplates from Porvair Sciences are manufactured at the very edge of injection moulding technology in order to avoid the use of potentially contaminating chemicals. Download the catalogue and report from:

Then you’ll see who’s whiter than white.
The Fritsch PULVERISETTE 19 with Cyclone is an efficient instrument to quickly comminute large volumes of cannabis. Plant material is fed into the instrument through a large funnel for fast throughput. Due to the efficiently designed cutting geometry of the rotating cutting edges of the rotor and the fixed knives in the grinding chamber, the sample material is automatically moved and comminuted increasingly fine by shearing forces between the knives. The negative pressure in the cyclone ensures a continuous flow through the cutting rotor and the selected sieve cassette for precise final fineness in a narrow particle size range. This prevents sample material from escaping during feeding and opens up new possibilities in the cannabis processing. The high throughput of up to 60lbs per hour is supported by large collection vessels of up to 65 litres.
The design of the grinding chambers in these mills
results in minimal dead space and exchangeable sieve cassettes make operation and cleaning straightforward
Eine komplett geöffnete Mahlkammer in wenigen Sekunden zur einfachen Schnellreinigung
Because the entire grinding chamber can be opened easily in seconds and both the rotor and the sieve can easily be removed with simple motions. Only with Fritsch Cutting Mills is it possible to lift open the entire top part of the housing as well as the front door, in fact, the door can be completely removed. This provides a completely open and empty grinding chamber with minimal dead space for easy and quick cleaning which results in a secure protection against cross contamination.
