The sample enters the grinding area between the pestle and mortar via hopper and is crushed by pressure and friction. The function of the scraper is to feed the material into the area between the mortar and pestle. This forced feed ensures that the whole sample is continuously subjected to the grinding and is also intensively mixed.

Easy to clean

Easy exchange of mortar and pestle without tools after grinding and it’s easy to clean the mill.

Easy and safe to operate
○The machine case and lid are made of hard alloy. 
○It is easy to operate and ergonomically designed. 
○The grinder is equipped with magnetic switch to judge whether the lid is closed or not, and the grinder only starts when lid is closed. 
○LED will light up when the observation window opened for easy observation of sample grinding process.

Skills to achieve the best grinding effect

○  Before preparing the paste samples, firstly you can put the mortar and sample (eg cocoa) into the drying oven and heat to 40℃.
○  In the preparation of chemicals and pharmaceuticals, please add grinding aid to prevent caking phenomenon.

Sample：yeast cells                                                   Grinding time：10 min
Property：hard,elastic                                                Grinding material：mortar and pestle of stainless steel
batch quantity：100g                                                 Grinding condition：Adding the Liquid Nitrogen during the grinding
Subsequent analysis：DNA extraction                      Final fineness：<5µm，homogenized powder  

*  It’s difficult to process some samples such as yeast cells. You’d better freeze the sample with liquid nitrogen to make them more brittle and easy to mill.
