Abstract

The utility model discloses a biochemical culture dish which comprises a cover and a bottom, wherein conical surfaces are arranged on two sides of the cover; three convex lenses with different amplification factors are arranged on the cover; three columnar protrusions are uniformly distributed on the inner wall of the cover; three grooves are uniformly arranged on the upper edge of the bottom; the groove consists of an upward vertical surface and a downward tilting inclined surface; two cylindrical containers are arranged below the bottom; and an opening of the cylindrical container is lower than an opening of the bottom. The biochemical culture dish has strong sealing performance, excellent ventilation and easy observation of the morphological structure of microorganisms.

Description

Biochemical petridish

Technical field

The utility model relates to the biochemical test utensil, relates in particular to a kind of biological culture utensil.

Background technology

In the prior art, biochemical test usually need be cultivated various mikrobes, utilizes mikrobe itself or the microbial metabolites cultivated, is used as experiment material.Mikrobe grows on substratum, except the hereditary property decision that receives itself, also receives the influence of many extraneous factors, and the kind of mikrobe is different, and best cultivation and condition are also had nothing in common with each other.According to the need situation of mikrobe, can they be divided into following five types to oxygen: aerobic microorganism, facultative aerobe, micro-aerobic microorganism, oxytolerant mikrobe and anaerobion, thus the demand to oxygen is not quite similar in culturing process.Development along with little aerobic, anaerobism and absolute technique of anaerobic incubation; Need in culturing process, replace gas in the petridish repeatedly, need the regulating and controlling temperature and humidity with the gas in methods such as physics, the chemistry absorption conversion petridish or with the gas of specific components.

Petridish ware of the prior art lid with at the bottom of the ware between contact the slit bigger, poor sealing performance, the various mikrobes in the environment are prone to pollute in the entering petridish, the while can not be regulated elasticity, has a strong impact on air permeability.In addition, petridish of the prior art can only be observed situation roughly in the petridish at the bottom of using transparent material as ware lid and ware mostly, is difficult for observing the mikrobe of structure relative complex of less while of some forms, observes not accurate enough for the mikrobe details.

The utility model content

The utility model technical problem to be solved is: provide that a kind of stopping property is strong, air permeability is good, be prone to observe the petridish of microbial morphology structure.

The technical scheme that its technical problem of the utility model solution is taked is: the biochemical petridish of the utility model; Comprise at the bottom of ware lid and the ware; The both sides of ware lid are provided with the conical surface, and ware covers and is provided with 3 convex lens that magnification is different, 3 columnar projections of uniform distribution on the ware lid inwall; Upper limb at the bottom of the said ware evenly is provided with 3 grooves; Groove is made up of a vertical surface that makes progress and an inclined downward, and the below at the bottom of the ware is provided with 2 cylindrical containers, and the opening of cylindrical container is lower than the ware bottom opening.

The technique effect that the utility model technical solution problem is obtained is: be provided with columnar projections owing to covering at ware; Upper limb is provided with groove at the bottom of the ware; When turning clockwise the ware lid, match at the bottom of ware lid and the ware in the protruding bottom that falls into groove along the inclined-plane of groove; Between the gap narrow down to minimum, reach the effect that improves sealing property; When being rotated counterclockwise the ware lid, protruding along rising on the inclined-plane of groove, along with the difference of convexity at incline position; Gap between at the bottom of ware lid and the ware increases gradually, realizes ventilation, when the needs anaerobism is cultivated; Can dioxide gas generation sheet be positioned in the cylindrical container at the bottom of the ware, in culturing process, carbonic acid gas slowly discharges; Replace oxygen, form anaerobic environment, strengthen air permeability.Owing to cover the convex lens that are provided with 3 different amplification at ware, when observing mikrobe, can select corresponding with it magnification according to mikrobe actual size situation, be easy to clearly observe the microbial morphology structure.

Embodiment

As shown in Figure 1, the biochemical petridish of the utility model comprises at the bottom of ware lid and the ware; The both sides of ware lid are provided with the conical surface, and ware covers and is provided with 3 convex lens that magnification is different, 3 columnar projections of uniform distribution on the ware lid inwall; Upper limb at the bottom of the said ware evenly is provided with 3 grooves; Groove is made up of a vertical surface that makes progress and an inclined downward, and the below at the bottom of the ware is provided with 2 cylindrical containers, and the opening of cylindrical container is lower than the ware bottom opening.

Manufacturing materials at the bottom of ware lid described in the utility model and the ware can be simple glass, quartzy or colourless transparent plastic.
