Introduction:The product is sensitive to heat sensitive substances, Chinese and Western medicine, animals and plants, rubber, plastic,

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.

凈信液氮冷凍組織研磨儀研磨臍帶避免樣品污染與浪費
臍帶是哺乳類的連接胎兒和胎盤的管狀結(jié)構(gòu),由兩條動脈和一條靜脈構(gòu)成。臍帶呈圓柱狀結(jié)構(gòu),內(nèi)有兩條臍動脈及一條臍靜脈。臍帶內(nèi)有一條臍靜脈,接受從母體來的新鮮血液并流經(jīng)胎兒全身回到胎兒的動脈系統(tǒng),最后進入兩條臍動脈流入胎盤至母體,這是胎兒血循環(huán)的特點之一。胎兒藉以生存的營養(yǎng)物質(zhì)如電解質(zhì)、無機鹽、激素、微量元素、免疫抗體等,均需經(jīng)過臍帶傳送。
