Abstract
The utility model discloses a kind of simple low temperature sclerous tissues dismembyators, and including the bolt A being oppositely arranged and bolt B, the junction of bolt A and bolt B is equipped with nut, and the upper end of nut is connected with the lower end of bolt A, and the lower end of nut and the upper end of bolt B connect.The present apparatus is low in cost for grinding to the sclerous tissues under low temperature.
Description
Technical field
The utility model belongs to biological experiment equipment technical field, is related to a kind of simple low temperature sclerous tissues dismembyator.
Background technique
Protocols in Molecular Biology is the powerful that the mankind disclose various physiological phenomenons and pathogenic mechanism, and the research of gene is
The indispensable important link of current life scientific domain.Wherein, many researchs are related to the extraction of tissue nucleic acid and protein.Energy
It is no by group be woven in low temperature, it is pollution-free under the conditions of sufficiently grind, be the important link for successfully extracting nucleic acid and albumen.By traditional
Method is easier to grind soft tissue carefully, but for sclerous tissues such as bone or cartilages, since tissue becomes very hard after cryogenic freezing
Firmly, it is not difficult to be ground carefully by professional instrument, the extraction efficiency of nucleic acid and protein is generally lower.Currently, in laboratory
Relatively conventional tissue grinder is only applicable to the grinding of soft tissue mostly, such as DS-1 type high-speed tissue mashing machine, is smash using this
Broken machine is ground the state for not being able to maintain tissue low-temperature, and cannot the maximum bioactivity for saving sample.Macro-organism
Company is usually using high-flux tissue dismembyator, and such as SCIENTZ-192 and BIO-24, above-mentioned lapping apparatus effective percentage is higher and protects
The advantage of tissue biological's activity is stayed, but price, all more than tens of thousands of members, cost is excessively high.
Utility model content
The purpose of the utility model is to provide a kind of simple low temperature sclerous tissues dismembyator, for the sclerous tissues under low temperature into
Row grinding, it is low in cost.
The utility model is the technical scheme adopted is that a kind of simple low temperature sclerous tissues dismembyator, including what is be oppositely arranged
The junction of bolt A and bolt B, bolt A and bolt B is equipped with nut, and the upper end of nut is connected with the lower end of bolt A, nut
Lower end and bolt B upper end connect.
The utility model is also characterized by
One end of connection stay cord on bolt A.
The other end of drawstring is connected with rubber hammer.
The beneficial effects of the utility model are as follows:
1. the present apparatus is easy to clean, dismantling, autoclave sterilization can be carried out, the pollution of tissue is avoided.
2. present apparatus small volume can be placed directly in liquid nitrogen container and carry out freezing processing, the usage amount of liquid nitrogen is saved.
3. bolt in the present apparatus, nut A, nut B and nut main component be iron, can keep longer after Liquid nitrogen precooler
The low-temperature condition of time is easy to the operation tested.
4. the internal diameter of present apparatus nut B is similar to the bore of 1.5ml test tube, tissue is easy to be transferred to test tube after grinding.

Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of simple low temperature sclerous tissues dismembyator of the utility model, as shown in Figures 1 to 3, including the bolt A1 being oppositely arranged
With bolt B 2, the junction of bolt A1 and bolt B 2 is equipped with nut 3, and the upper end of nut 3 is connected with the lower end of bolt A1, nut
3 lower end is connect with the upper end of bolt B 2.
One end of connection stay cord 4 on bolt A1.
The other end of drawstring 4 is connected with rubber hammer 5.
A kind of application method of simple low temperature sclerous tissues dismembyator of the utility model is, by the nut and workbench of bolt B 2
The lower end of nut 3, is screwed in the stud upper end of bolt B 2, then (bone or cartilage specification are about by bone or cartilage to be ground by contact
Be put into 3 inner ring of nut for 2mm*2mm*2mm), then the stud lower end of bolt A1 be screwed in 3 upper end of nut, bone to be ground or
Cartilage is located in the cavity of the formation inside nut 3, and freezing was pulled out device by drawstring 4 after 3-5 minutes in liquid nitrogen container, so
Tapped afterwards by nut of the rubber hammer 5 to bolt A1, by tap the vibration generated by the bone placed in nut 3 or
Cartilage is shatter, plays the effect of grinding.Since bone or cartilage to be ground freezed in liquid nitrogen, thus it is very hard
It is crisp, it is easily crushed after by larger external force under low-temperature condition, in powdered.When present apparatus freezing processing in liquid nitrogen container, can lead to
It crosses drawstring 4 and pulls out the present apparatus from liquid nitrogen container.
