Product Introduction:

A． High accuracy and reproducibility of data
1. The sample is always at liquid nitrogen temperature during grinding
2. 1The sample cools to -100 within minutes ℃，4It can reach -196 in minutes and 30 seconds ℃
3. The sample vial is fully enclosed during the crushing process, and the sample remains intact in the bottle to ensure control of dangerous and important samples.
4. The sample vials are independently sealed, making it very convenient to clean after each crushing, avoiding cross-contamination between samples and external contamination.
B . Multifunctional, user-friendly design
1. Touch display screen, which can set parameters such as grinding time, cycle period, grinding operation frequency (optional)
2. Removable control panel (optional)
3. Can store 10 programs (optional)
4. Can be installed 1.5 ML 2ML 5ML 10ML 25ML 50ML Wait for sample tubes and grinding
C . Durability
1. There is only one moving part-collider, which greatly reduces mechanical stress and extends the service life of the equipment
2. Strong technical support: Shanghai Jingxin Company has more than 500 users, professional sample preprocessing instrument production

Technical parameters 
1)   It has five major systems, sample grinding system, liquid nitrogen storage system, liquid nitrogen control system, circuit control system, insulation and cooling system
2)   Application areas: Biology, Food, Agriculture, Medicine, Chemistry  / Synthetic materials, engineering /Electronics, Construction Materials, Glass /ceramics
3)   Automatic liquid nitrogen filling: The liquid nitrogen flow can be controlled throughout the process and can be filled at any time during operation.
4)   There are two types of liquid nitrogen grinding operation methods: manual and fully automatic
