Description
Technical Field
The utility model relates to a microbiological test equipment technical field, it is specific, the utility model relates to an open-close type oxford cup frame.
Background
Currently, in the research on the development of preservatives and antibacterial agents, the bacteriostatic activity of plant extracts and medicines, the screening of biocontrol active bacteria and the like, the determination of the bacteriostatic activity is an essential step, the minimum bacteriostatic concentration can be determined for evaluating the bacteriostatic performance of the plant extracts and medicines, and the main methods include a liquid dilution method and a flat diffusion method. The plate diffusion method, namely the bacteriostatic zone test, is mainly a qualitative test and comprises a filter paper sheet method, an oxford cup method and a punching method. However, all three methods have disadvantages, the filter paper sheet method: the edge of the filter paper is frizzy, and the generated inhibition zone is easy to be irregular; the bacteriostatic substances adsorbed by the filter paper sheets cannot be accurately controlled, and the sizes of bacteriostatic zones are different; the accuracy is lower than that of the Oxford cup method and the punching method. Oxford cup method: the experimental operation has more attention links and low fault tolerance rate, if the liquid level of the agar is slightly uneven, the oxford cup cannot be in close contact with the agar, and substances to be detected in the oxford cup are easy to leak; the oxford cup is poor in stability and easy to fall, and the oxford cup is required to be kept horizontal when moving or placing a culture dish, and is inclined slightly, so that the oxford cup can be inclined or poured, and substances to be detected in the oxford cup can not be uniformly diffused all around. A punching method: rifle head, hole puncher and oxford cup are used commonly in the laboratory and punch at the upper culture medium, and rifle head and hole puncher punch and all need pick out downthehole agar, and time-wasting and hole edge agar are fragile, and still fragile lower floor's culture medium leads to the degree of depth inconsistency of every aperture, and the volume is different, influences the accuracy that detects. Although the lower culture medium cannot be damaged when the oxford cup is punched, agar at the edge of the hole can be damaged when the oxford cup is taken out by using tweezers, and the agar in the hole also needs to be removed when the operation is wrong; after the oxford cup is placed, when the upper culture medium is added, the position of the oxford cup can be moved by liquid impact, and the arrangement of the bacteriostatic holes is influenced. Three methods of the zone of inhibition test all need to pay attention to the position of placing scraps of paper, oxford cup and punching, if can not evenly distributed, or spatial distance is unchangeable, all easily appear the phenomenon that the zone of inhibition overlaps, and then influence experimental effect, and this is the problem that experimenter can't the eye measurement, also can't avoid through meticulous and cautious. Therefore, the invention of an openable oxford cup holder has become a technical problem to be solved by those skilled in the art.
