Description

Liquid nitrogen grinder prevents frostbite and hinders

Technical Field

The utility model relates to a biology, chemistry experiment field, concretely relates to prevent frostbite and hinder liquid nitrogen grinder.

Background

Liquid nitrogen is a reagent commonly used in biochemical experiments, and particularly in biological experiments, liquid nitrogen is often used for freezing a material of a gene to be extracted, and after freezing, a grinding bowl is adopted for grinding, and subsequent gene extraction operation is carried out. In specific experimental operation, operating personnel often wears thick heavy protective gloves, and handheld grinding alms bowl and grinding rod grind, and the operation is difficult, spills over the material very easily, and takes single thin gloves to be frostbite by the liquid nitrogen very easily again.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that the operating personnel operate inconveniently and easily freeze injury during the biochemistry experiment adopts the liquid nitrogen to grind, and provides a liquid nitrogen grinder prevents frostbite.

The utility model relates to a liquid nitrogen grinder of frostbite damage prevention, which comprises a mortar, a grinding rod, a mortar cover and a base;

the mortar lid in the middle of be provided with the hole, grinding rod upper end pass the hole to be connected with the mortar lid through grinding rod cover, the base in the middle of the department seted up the mortar and place the shrinkage pool, the mortar arrange the shrinkage pool of department in the middle of the base in.

The utility model discloses contain following beneficial technological effect:

the utility model discloses a setting up and grinding the alms bowl lid, grinding the alms bowl lid and grinding alms bowl phase-match on grinding the alms bowl, prevent overflowing of liquid nitrogen and material, lead to the loss of operating personnel frostbite or material. In order to realize grinding, the utility model discloses department sets up the hole in the middle of grinding the alms bowl lid, passes the grinding rod hole to link together it and grinding alms bowl lid through grinding the stick cover, the grinding stick cover adopts soft and low temperature resistant-196 degrees nylon cloth to make, can adopt low temperature resistant glue (for example resistant-200 ℃ low temperature epoxy structural adhesive etc.) to paste the grinding rod cover on grinding rod and grinding alms bowl lid. The size is adjusted according to actual conditions, so that the operator can conveniently operate the grinding rod to grind. In order to observe the grinding condition at any time, an observation area is arranged on the grinding bowl cover, and the observation area is made of low-temperature-resistant plastic materials (such as PCTFE and low-temperature-resistant FPP). The sample grinding condition in the grinding bowl can be observed conveniently. The utility model discloses a grinding rod head is provided with a plurality of plush coppers, can make and grind more thoroughly. The utility model discloses a base is used for placing and fixed grinding alms bowl, and department sets up the grinding alms bowl in the middle of the base and places the district, grinds the alms bowl and places it in to be provided with the skid resistant course (can be silica gel etc.) in the stage, the heat preservation (can be asbestos etc.). The utility model discloses a base can be in the fixed grinding alms bowl in grinding to play certain heat preservation effect. The utility model discloses simple and practical, the effect is showing, can effectively solve the problem that operating personnel operated inconveniently and frostbite easily.
