Abstract
The utility model discloses a waste liquid culture medium sucking device for a laboratory. The waste liquid culture medium sucking device is characterized by comprising a liquid storage bottle, a buffer bottle, a vacuum pump and an elbow drip tube, the elbow drip tube is connected with the liquid storage bottle by a rubber tube a, the liquid storage bottle is connected with the buffer bottle by a rubber tube b, and the buffer bottle is connected with the vacuum pump by a rubber tube c. The waste liquid culture medium sucking device has the advantages that the waste liquid culture medium sucking device is simple in structure and convenient to assemble, the sterilized elbow drip tube is placed in a biological safety cabinet, and is connected with the rubber tube a as needed, and the vacuum pump is started, so that waste liquid culture media can be transferred from the inside of the biological safety cabinet to the outside of the biological safety cabinet to be treated; the waste liquid culture medium sucking device is speedy and convenient and does not occupy space, and the utilization efficiency of the biological safety cabinet is improved; bacterial contamination is prevented, and experimental effects are guaranteed; the device can be reused, and extra expense is omitted; as a disposable sterilization pipette tip is omitted, the experimental cost is effectively lowered.
Description
Technical field
The utility model relates to a kind of laboratory apparatus, is specifically related to a kind of laboratory device of drawing the liquid waste substratum.
Background technology
Liquid nutrient medium is the aqueous substratum of microorganism or animal and plant cells, is widely used in the biology laboratory, and cell need be changed a subculture every 1-3 days in culturing process.To used substratum, common way is directly substratum to be poured out from the cell bottle, and this method waste liquid very easily is infected with bottleneck, causes microbiological contamination; Or utilize liquid-transfering gun from culture dish, porous plate, one to manage sucking-off, and during operational cost, reduce working efficiency, expend a large amount of liquid-transfering gun head costs.Above method all need be handled a large amount of discarded substratum in Biohazard Safety Equipment, take up room and be very easy to cause pollution, influences experimental result.
The utility model content
At problems of the prior art, the utility model purpose is to provide the device of a kind of laboratory with absorption liquid waste substratum.
The utility model is realized by the following technical programs:
Described a kind of laboratory device of drawing the liquid waste substratum, it is characterized in that this device comprises reservoir, surge flask, vacuum pump, elbow dropper, link to each other, link to each other, link to each other by rubber hose c between surge flask and the vacuum pump by rubber hose b between reservoir and the surge flask by rubber hose a between described elbow dropper and the reservoir.
Described a kind of laboratory device of drawing the liquid waste substratum, it is characterized in that described reservoir and surge flask are the triangular flask that the middle part has outlet, and the upper shed of triangular flask all seals the single hole rubber plug is set, and pegging graft in the described single hole rubber plug is provided with the double glazing pipe.
Described a kind of laboratory is characterized in that with the device of drawing the liquid waste substratum end socket of described rubber hose a is arranged on the elbow dropper, and the other end socket is arranged on the double glazing pipe on the reservoir.
Described a kind of laboratory is with the device of drawing the liquid waste substratum, and its feature is arranged on the reservoir centre exit in described rubber hose b one end socket, and the other end socket is arranged on the double glazing pipe on the surge flask.
Described a kind of laboratory is characterized in that with the device of drawing the liquid waste substratum described rubber hose c one end is socketed on the surge flask centre exit, and the other end socket is arranged on vacuum pump bleeding point end.
A kind of laboratory of the utility model is with the device of drawing the liquid waste substratum, and is simple in structure, easy to assembly.By the elbow dropper after the sterilization is placed in the Biohazard Safety Equipment, connect rubber hose a when needing, the unlatching vacuum pump can be transferred to discarded liquid nutrient medium outside the cabinet in Biohazard Safety Equipment and handle, and rapid and convenient, do not take up space, improve the service efficiency of Biohazard Safety Equipment; Avoid bacterial contamination, guarantee experiment effect; But this device repeated multiple times is used simultaneously, can not produce extra-expense; Owing to do not need to use primary sterilization liquid-transfering gun head, effectively reduce experimental cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with Figure of description the utility model is described in further detail, and provides embodiment.
As shown in the figure, a kind of laboratory of the utility model device of drawing the liquid waste substratum, this device comprises reservoir 1, surge flask 2, vacuum pump 3, elbow dropper 7, the setting of surge flask 2 is avoided discarded medium liquid is drawn in the vacuum pump 3, wherein reservoir 1 and surge flask 2 are the glass triangle bottle that the middle part has outlet, adopt the convenient amount of in time observing liquid in the bottle of vial, the upper shed sealing of reservoir arranges to peg graft in single hole rubber plug 8-1 and the hole double glazing pipe 9-1 is set, and the upper shed sealing of surge flask arranges to peg graft in single hole rubber plug 8-2 and the hole double glazing pipe 9-2 is set; Link to each other by rubber hose a4 between elbow dropper 7 and reservoir 1, an end socket that is specially rubber hose a4 is arranged on the elbow dropper 7, and the other end socket is arranged on the double glazing pipe 9-1 on the reservoir 1; Link to each other by rubber hose b5 between reservoir 1 and the surge flask 2, be specially rubber hose b5 one end socket and be arranged on reservoir 1 centre exit, the other end socket is arranged on the double glazing pipe 9-2 on the surge flask 2; Link to each other by rubber hose c6 between surge flask 2 and the vacuum pump 3, be specially rubber hose c6 one end and be socketed on surge flask 2 centre exits, the other end socket is arranged on vacuum pump 3 bleeding point ends.
During use, open vacuum pump, the end socket of rubber hose a4 is arranged on the elbow dropper 7, the elbow of elbow dropper 7 is put into Tissue Culture Flask, culture dish or porous plate, can directly discarded substratum be sucked into outside the Biohazard Safety Equipment.In the use, for handling dissimilar liquid, the sterilization that carries out disinfection of available alcohol swab wiping elbow dropper.After finishing using, rubber hose a4 directly extracted from elbow dropper 7 get final product, elbow dropper 7 simply cleans alcohol disinfecting again after experiment finishes.Adopt this device, can effectively reduce the infectation of bacteria rate, guarantee experiment effect, this device is simple to operate simultaneously, and is time saving and energy saving, can effectively improve cut-and-try work efficient.
