Description
Technical field
This scheme relates to a kind of use for laboratory equipment technical field, specifically a kind of manual operation rack for test tube.
Background technology
There is no in the market the batch inoculation rack for test tube using in sterile working, all to adopt manual operations to carry out at present, utilize alcolhol burner to assist to build gnotobasis, operating process is: first pull out the female pipe of bacterial classification tampon, picking mycelia or bacterium piece, cover again tampon, be placed on table top, to pick up again wait inoculating test tube and pull out tampon bacterial classification is put into and after inoculating test tube, covered tampon again.Inoculation is exactly to repeat above process in batches.Efficiency is low, operates the absolutesterility region that the unskilled test tube mouth that makes bacterium piece or the mycelia of picking and pull out tampon is built away from alcolhol burner, and causing polluting probability increases.
In sterile working, the most important thing is contaminated solution problem, inoculation also will solve efficiency in batches.
(1) in operating process contaminated solution most critical be to prevent that the bacterium piece of picking or mycelia are exposed to airborne overlong time, another is to reduce as far as possible in vitro culture medium with the time of contact of air.Object is all to avoid airborne miscellaneous bacteria to take advantage of a weak point to cause polluting.The time that the mycelia of existing manual operation picking or bacterium piece expose in air is longer, and the absolutesterility region that alcolhol burner is built is less, is easy to just free this region, and polluting probability increases.
(2) alcolhol burner is easily overturned in use procedure, and alcohol leaks and causes fire and personal injury, also can damage experiment material.
(3) in seeded process, will repeatedly pick and place the female pipe of bacterial classification and test tube to be inoculated in batches, efficiency is lower.
