Abstract
The utility model relates to a pretreatment device for quickly preparing a fresh tobacco leaf sample of metabonomics. The pretreatment device is characterized by comprising a stainless steel sample tray with a handle and a solid box body which is made of foam plastic material, wherein the center of the solid box body is provided with a settling tank with the shape being matched with the sample tray and used for holding liquid nitrogen, the bottom of the settling tank is provided with a tray supporting foot, and the board of the solid box body on one side of the settling tank is provided with a handle support for supporting the sample tray handle. The pretreatment device has the advantages that: 1, the sample treatment process is carried out in the liquid nitrogen, so that the variation of different substances in the sample can be prevented; 2, the sample is convenient to take out, the cold injury of the operation personnel caused by careless operation can be prevented, and safety and reliability can be realized; 3, simplicity, convenience and easiness in operation can be realized, the sample pretreatment time can be saved, and the pretreatment device is a simple and practical pretreatment tool for the tobacco leaf sample.
Description
Technical field
The utility model relates to fresh tobacco sample pretreating device, specifically a kind of fresh tobacco sample of metabolism group pretreating device of preparation fast that is applicable to.
Background technology
The preparation of fresh tobacco sample is the precondition of tobacco metabolism group research, and the fresh tobacco sample being collected carries out ultralow temperature transportation by liquid nitrogen or dry ice.In the process of metabolism sample preparation, metabolism sample need to be carried out to elementary pulverizing, then carry out freeze-drying and separating twice processing.The process of the elementary pulverizing of metabolism sample is called the pretreatment stage of metabolism sample, for guaranteeing sample preparation quality, pretreatment stage whole process must be carried out in liquid nitrogen, after elementary pulverizing completes, needs again immediately liquid nitrogen to be poured out, sample is packed with masking foil rapidly, put into dry ice.While using prior device operation, sample takes out and will carry out liquid nitrogen and topple over, and liquid nitrogen frostbite staff's situation easily occurs hand operation; And if in sample, have liquid nitrogen remaining, and directly contact with dry ice, have a large amount of steam and discharge, easily cause security incident.The reducing mechanism using is at present canister, and outer wall easily forms a large amount of condensate water, affects the quality of sample.
Summary of the invention
A kind of fresh tobacco sample of metabolism group pretreating device of preparation fast that is applicable to that the purpose of this utility model designs for above-mentioned prior art situation just, utilize this pretreating device, can make sample preparation whole process carry out in liquid nitrogen, prevent the variation of various materials in sample, and be convenient to the taking-up of sample, prevent operating personnel's the frostbite causing because of careless manipulation, safe and reliable.
The purpose of this utility model is achieved through the following technical solutions:
A kind of fresh tobacco sample of metabolism group pretreating device of preparation fast that is applicable to, comprise that one with the stainless steel sample tray of handle and the solid case body of a polyfoam material, solid case body central authorities offer that a shape and sample tray match for holding the deep gouge of liquid nitrogen, deep gouge bottom is provided with 3-4 pallet feet, stainless steel sample tray try to get to the heart of a matter for double-layer stainless steel net form mesh-structured.
The solid case body table top that is positioned at deep gouge one side is provided with for supporting the handle bracket of sample tray handle.
Described stainless steel sample tray is that low temperature resistant stainless steel is prepared from.
During use, first sample tray is put into the deep gouge of foam casing, tray handle is placed on tray handle support, now in deep gouge, add liquid nitrogen, when liquid nitrogen liquid level has just covered stainless (steel) wire and overflows, stop adding liquid nitrogen.In sample tray, add sample, carry out elementary pulverizing.After pulverizing completes, pallet end is risen, liquid nitrogen drains to rapidly in casing deep gouge, after liquid has leaked, rapidly sample is poured in masking foil and is packed.Pallet feet is set in casing, prevents that pallet from contacting with casing large area, sticks together under condition of ultralow temperature.Double-layer stainless steel net, is 20 order apertures, and two layers of mesh vertically arranges, and can prevent from leaking under sample, can guarantee again the pallet that frees in and out of liquid nitrogen.
The utility model has the advantage of:
1, sample preparation whole process is carried out in liquid nitrogen, prevents the variation of various materials in sample.
2, be convenient to the taking-up of sample, prevent operating personnel's the frostbite causing because of careless manipulation, safe and reliable.
3, simple and convenient, easy operating, saves time for sample pretreatment, and can yet be regarded as a kind of is simple and practical tobacco sample pre-treatment tool using.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, casing, 2, pallet feet, 3, support 4, sample tray, 5, handle, 6 double-layer stainless steel nets, 7, deep gouge.
Embodiment
The utility model is further described below in conjunction with accompanying drawing:
As shown in Figure 1: a kind of fresh tobacco sample of metabolism group pretreating device of preparation fast that is applicable to, comprise that one with the stainless steel sample tray 4 of handle 5 and the solid case body 1 of a polyfoam material, solid case body central authorities offer that a shape and sample tray match for holding the deep gouge 7 of liquid nitrogen, deep gouge bottom is provided with 3-4 pallet feet 2, stainless steel sample tray try to get to the heart of a matter for double-layer stainless steel net 6 form mesh-structured.
The solid case body table top that is positioned at deep gouge one side is provided with for supporting the handle bracket 3 of sample tray handle 5.
Described stainless steel sample tray 4 is prepared from for low temperature resistant stainless steel.
