Description
Technical Field
The invention relates to human living goods, in particular to a garbage separation technology, and specifically relates to a laboratory solid garbage separation device.
Background
With the iterative update of cell biology and molecular biology technologies, large-volume liquid storage and transfer devices such as large-capacity beakers and glass pipettes gradually exit the history stage. Microcentrifuge tubes (EP tubes, from 200. mu.l to several thousand. mu.l) and micropipettes (also called pipette guns, various specifications from 0.1. mu.l to 1000. mu.l) of different volumes have long been common consumables in laboratories. But with it the problem of solid waste classification arises: the disposable plastic tips (commonly called tips) used in conjunction with these small-volume microcentrifuge tubes and micropipettes are small in volume. And many experiments need to operate on ice, so when the experiment ended, often the experimenter was when empting the garrulous ice of ice chest, and did not sort out the microcentrifuge tube in the garrulous ice or even rifle head to pour the garrulous ice into the sewer together with microcentrifuge tube, rifle head etc. and lead to the sewer jam.
In addition, agarose gel, polyacrylamide gel, and the like used for detection of nucleic acids and proteins in molecular biology experiments are soft and fragile. The required electrophoresis tank of experiment, system gluey glass board are washd to the experimenter in the laboratory basin and are made the disintegrating slag of gel viscidity in the plastics of sewer and strain the stopper often, if do not handle for a long time, have mould to breed on the one hand, and the plastics filter that on the other hand blockked up floats easily when rivers are torrent, leads to bulky experiment consumptive material to flow in the sewer U-shaped pipe, has further aggravated the sewer and has blockked up the degree.
Finally, although cages for raising laboratory animals (mice, rats, etc.) required for biological or medical experiments are frequently cleaned, fine-grained bedding materials for raising animal excrements, corncobs, wood chips, etc. sometimes adhere to the cages and block plastic plugs during cleaning.
Although nylon filter screens are available on the market which can be sleeved on plastic filter plugs of sewers, on one hand, the possibility of blockage of the sewers is reduced, and on the other hand, the nylon filter screens are convenient to replace and are beneficial to cleaning. But because the plastic filter plug and the nylon filter screen are both light in weight, the plastic filter plug and the nylon filter screen are very easy to float when a large water flow cleaning device is used in a laboratory, and the function of preventing the sewer from being blocked is lost; in addition, the diameter of the common sewer plastic filter plug is only a few centimeters, even if a laboratory avoids a large water flow cleaning device, the fine holes of the filter plug are easily blocked by gel, a gun head and the like falling on the filter plug, and if the nylon filter screen is used for reducing the blockage of the sewer, the nylon filter screen needs to be frequently replaced.
