Abstract
The utility model a culture medium constant temperature sampler, being composed of a sampling cylinder, a floating piston, a piston with a rod and an efflux tube. A lower section and a side section of the sampling cylinder is provided with the floating piston and an outlet, the upper section is provided with the piston with a rod and a cover, and the upper part of the rod is provided with a baffle plate and a spring. The sampling is quick, the temperature reduces little, the spreading of the culture medium is uniform, and the operation is convenient.
Description
The utility model relates to a kind of nutrient culture media constant temperature sampler, mainly supplies drug test as sampling appliance.
Existing medicine such as titer of antibodies are measured the two point picture dotted portion that sampling apparatus is seen Fig. 1, are with stopple coupon 14 and a rubber pocket 15 of scale 13 to constitute by one.Keep constant temperature in the constant temperature oven, be generally 60 ℃.Take out its quantity of naked-eye observation behind the sample, as measure many or amount not enough, insert again and extrude in the sample liquid or further suck, treat that the sample amount is suitable, it is clamp-oned in two dish.Its weak point is: sampling and observation are more loaded down with trivial details, are difficult to grasp temperature, cause the sample liquid cooling but not flow out easily or are difficult for evenly spreading out, and cause the defective of can not take a sample and resampling.
The purpose of this utility model is to overcome above-mentioned weak point of the prior art and a kind of simple to operate, quick and nutrient culture media constant temperature sampler that nutrient culture media evenly spreads out easily is provided.
The purpose of this utility model can reach by following measure: the utility model is made up of sampler barrel, the piston that moves about, piston with rod and effuser, hypomere and other section have the piston of moving about and outlet in the sampler barrel, epimere has piston with rod and lid, and baffle plate and spring are arranged at bar top.
Accompanying drawing is total figure of the present utility model, and two point is drawn dotted portion and represented prior art.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:
Fig. 1 represents total figure of the present utility model, and sampler barrel 1 is fixedly connected in the incubator 2, stores nutrient culture media 3 in the incubator, in the incubator is to keep constant temperature, and present embodiment is 60 ℃.Hypomere in the sampler barrel and other section have floating piston 4 and outlet 7, and the piston 6 of band bar 5 is arranged in the epimere of sampler barrel, and other section outlet top is connected to soft effuser 8.There is baffle plate 9 bar 5 upper ends, between bar 5 external sampling covers 10 and the baffle plate spring 11 are arranged.Reducing section 12 is arranged between sampler barrel epimere and the hypomere.
According to required sampling amount, matched spring during use.During sampling, only need hand baffle plate 9, treat the hand spring after press, piston 6 is discharged piston cavity of resorption gas from outlet.The piston 4 of hypomere is depressed and fills in the bottleneck that is encapsulated in the sampler barrel hypomere, and other section floating piston rises, and directly other section of air and effuser are overflowed in the sampler barrel.Loose one's grip then, piston 6 restores under the elastic force effect at spring and rises, and the floating piston of hypomere rises thereupon, and other section floating piston descends, and sealing outside air can not enter, and nutrient culture media enters the sampler barrel hypomere until piston 6 belows.Hand baffle plate once more, piston 6 descends, and nutrient culture media is extruded through flexible pipe 8 from exporting 7, enters in the dish, and sampling is finished.Because operation rapidly; Can guarantee that nutrient culture media evenly spreads out, reach the sampling purpose.
The utility model contrast prior art has can guarantee that culture medium evenly spreads out, takes a sample quick and easy and simple to handle Advantage.
