Cryogenic Grinder (manual liquid nitrogen freezing) JXFSTPRP-II-02 (patented product, counterfeiting must be investigated! 201620363493X)
Application range of liquid nitrogen grinder:
The product is sensitive to heat sensitive substances, Chinese and Western medicine, animals and plants, rubber, plastic, (root, stem, leaf, flower, fruit, seed, brain, heart, lung, stomach, liver, thymus, kidney, intestine, lymph node, muscle , bones, fungi, bacteria, food, medicines, coal, oil shale, wax products, PE, PS, textiles, resins), etc. and materials that are tough at room temperature and cannot be crushed.
The liquid nitrogen grinder is to first freeze the above-mentioned substances below the embrittlement point, and then grind them 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.
Main technical features:
A. High data accuracy and reproducibility
1. During the grinding process, the sample is always at an ultra-low temperature facilitated by liquid nitrogen.
2. Theory The sample is cooled to -100 within 1 minute. C, can reach -196 in 4 minutes and 30 seconds. C
3. The sample is in a completely closed state during the crushing process, and the sample is completely kept in the grinding tube to ensure the control of dangerous and important samples.
4. The sample bottles are independently sealed, and it is very convenient to clean after each break, avoiding cross-contamination between samples and external contamination
B. Versatility, humanized design
1. LCD display, can set parameters such as grinding time and grinding operation frequency (optional)
2. Movable control panel (optional)
3. Can store 10 programs (optional)
4. Sample tubes such as 1.5ML 2ML 5ML 10ML 25ML 50ML 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 2000 users, professional sample pretreatment equipment production
Experimental case:
1. Test Method for Grinding Corn Seed with Tissuelyser® Plant Tissue Grinder | 2. Test method for grinding citrus peel tissue with Tissuelyser® plant tissue grinder |

Steps:
1. Manual operation
(1) Manually immerse the adapter and grinding jar into the liquid nitrogen sample, and quickly cool down to -196 degrees. Prevent sample degradation or enable changes in sample physical properties
(2) Add the liquid nitrogen tank to the liquid nitrogen tank in the cavity, and reduce the temperature in the cavity to a low temperature through the effect of liquid nitrogen, thereby ensuring that the entire grinding process is in a low temperature state
(3) Put the adapter and grinding jar on the grinder. Cover the safety cover and lock the safety lock to operate.
