We have 8 types of cast polyamide jars in the range from 1 litres to 30 litres. Grinding jars made from high wear-resistant cast polyamide have a low weight (60% less than jars made from porcelain). As a result they are very easy to handle. Optimized for laboratory applications the jars have high impact resistance. Furthermore they are easy to clean and produce very little noise. They are resistant to a lot of chemicals, produce low contamination factors and are suitable for food stuff. Grinding balls made from ceramic material can be used.
