Brand：Shanghai Jingxin
Specifications ：PCS
Introduction：The liquid nitrogen grinder first freezes the above-mentioned substances below the embrittlement point, and then is ground to the required fineness in the grinder, and the original ingredients will not be destroyed.
Automatic liquid nitrogen freezing grinding machine JXFSTPRP-II-01 (patented product, counterfeiting must be punished! 2016214095849)
Application range:
This product is specially used to grind heat-sensitive substances, various animal and plant tissues, microorganisms, rubber, plastics, food, medicine, coal, oil shale, wax products, PE, PS, textiles, resins, etc., and exhibits toughness at room temperature. Substances that are difficult to crush.
The liquid nitrogen grinder first freezes the above-mentioned substances below the embrittlement point, and then is ground to the required fineness in the grinder, and the original ingredients will not be destroyed. In addition, flammable and explosive substances at room temperature can also be crushed at low temperature, and the effect is more significant.
Features:
A. High data accuracy and reproducibility
1. The sample is always at liquid nitrogen temperature during the grinding process
2. The sample is cooled to -100°C within 1 minute, and it can reach -196°C within 4 minutes and 30 seconds
3. The sample bottle is in a fully enclosed state during the crushing process, and the sample is completely kept in the bottle to ensure the control of dangerous and important samples.
4. The sample bottles are all sealed independently, it is very convenient to clean after each crushing, to avoid cross-contamination between samples and external contamination
B. Versatility, humanized design
1. Touch screen, can set the grinding time, cycle period, grinding operation frequency and other parameters (optional)
2. Removable control panel (optional)
3. 10 programs can be stored (optional)
4. 1.5ML 2ML 5ML 10ML 25ML 50ML and other sample tubes can be installed for sample grinding
C. Durability
1. There is only one moving part-the collider, which greatly reduces the mechanical stress and prolongs the service life of the equipment
2. Strong technical support: Shanghai Jingxin Company has more than 500 users, professional sample pre-processing equipment production
Grinding comparison：
Operation steps of liquid nitrogen refrigerated grinder
1. Manual operation
(1) Manually immerse the adapter and grinding tank in the liquid nitrogen sample, and quickly cool down to -196 degrees. Prevent sample degradation or change the physical characteristics of the sample
(2) Install the adapter and the grinding jar on the grinding machine. Put on the safety cover and lock the safety lock for operation.
2. Automatic operation
(1) Install the adapter and grinding jar on the grinder. Put on the safety cover and lock the safety lock for operation.
(2) Open the liquid nitrogen connection device, start the liquid nitrogen delivery/or open the air refrigeration instrument (to achieve 0 degree refrigeration)
(3) Turn on the liquid nitrogen control switch. After the liquid nitrogen flows into the crushing tank, the temperature is physically cooled. In about a minute, the temperature quickly drops to -192 degrees
(4) Turn on the grinding button to operate. It only takes 15 seconds to crush the object instantly.
(5) The flow of liquid nitrogen can be controlled in the whole process, and it can be charged at any time during the operation.
