Description
Technical field
The utility model relates to biological experiment clothing arts, is specifically related to liquid nitrogen bottle in a kind of superclean bench and fixes tilting device.
Background technology
Liquid nitrogen (is often written as LN
2), be the liquid form that nitrogen is formed at low temperatures.The boiling point of nitrogen is-196 ° of C, if temperature will form liquid nitrogen at-196 ° of below C at normal atmospheric pressure; If pressurization, can obtain liquid nitrogen at higher temperatures.Liquid nitrogen is used in molecular biology experiment in a large number, such as extract plant genomic DNA or RNA, all need to get blade or plant tissue grinds in mortar, this process need adds a large amount of liquid nitrogen, especially the extraction of RNA, is extremely easily polluted, and RNA is degraded, need to sterilize as much as possible and seal, so this process is carried out in superclean bench.According to " Leidenfrost effect ", human body directly can contact liquid nitrogen, and skin can not frost bitten.Because liquid nitrogen temperature is very low, touch liquid nitrogen bottle through conventional hand, hand can be made to do not feel like oneself.In addition in superclean bench, arm activity is restricted, and it is more inconvenient to topple over liquid nitrogen, is easily poured on estrade.Because super-clean bench is a semitight environment, and have alcolhol burner to burn, temperature is higher, although liquid nitrogen storage is in air-tight bottle, has gap after all, can accelerate the volatilization of liquid nitrogen, cause damage.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides liquid nitrogen bottle in a kind of superclean bench to fix tilting device, and this tilting device makes, without the need to direct body contact's liquid nitrogen, to avoid the injury to laboratory technician's hand, and structure is simple simultaneously, easy to operate.
The purpose of this utility model carrys out specific implementation by the following technical programs:
In a kind of superclean bench, liquid nitrogen bottle fixes tilting device, mainly comprise box body and Foldable handle, described box body is provided with the first breach and the second breach, Foldable handle is positioned at the second indentation, there and can moves along the second breach, first collar for extracting liquid nitrogen body is fixed with in the front end of Foldable handle, the inside of box body is provided with middle bracket and lower bracket, described lower bracket is fixed on box body, described middle bracket one end and lower bracket hinged, the other end is fixed on Foldable handle, described middle bracket is provided with second collar for holding up at the bottom of liquid nitrogen bottle.
Further, described Foldable handle comprises the grip part and support portion that are hinged, and described first collar is fixed on the front end of support portion, and described middle bracket is fixed on the sidewall of support portion.
Further, the tail end of described grip part is provided with fixture block, side arm corresponding with grip part on described box body is provided with the draw-in groove that can be interlocked with fixture block.
Further, be provided with ice cube in described box body and take up space, ice cube takes up space and is placed with ice cube.
In a kind of superclean bench of the utility model, liquid nitrogen bottle fixes tilting device, this tilting device comprises box body and Foldable handle, comprise multiple center rest for supporting simultaneously, handle is provided with for being socketed first collar and second collar that support liquid nitrogen bottle, liquid nitrogen bottle can be driven freely to rotate by handle, touch liquid nitrogen bottle without the need to hand, avoid laboratory technician's hand not feel well, topple over liquid nitrogen convenient, prevent from being poured on estrade; Folding handle can be saved and take up room, and the tail end of Foldable handle grip part is provided with the fixture block matched with draw-in groove and can plays fixation; Ice cube takes up the ice cube placed in space can reduce environment temperature around liquid nitrogen bottle, and the evaporation rate of the liquid nitrogen that slows down, has higher practicality and commercial promise.
