Abstract
The utility model discloses a filter. The filter comprises a filter body, wherein the upper part of the body is provided with an air inlet and a liquid filling hole; a liquid filling hole cover is matched with the liquid filling hole; a base is connected with the lower part of the body; a liquid outlet is arranged below the base; and control valves are respectively arranged at the air inlet and the liquid outlet. The filter is characterized in that the body is provided with a volume receptor; a pressoreceptor is arranged near the air inlet; and a disassembly adjusting support structure is arranged below the base. The filter has the following advantages that: by arranging the pressoreceptor and the volume receptor on the filter and arranging the adjusting support structure below the base, the height of the filter is adjustable, the pressure and volume of the filter are controllable and the filter is convenient to use.
Description
Technical field
The utility model relates to a kind of filter, is specifically related to a kind of filter that is used for the life science test.
Background technology
In the prior art, in many research work of life science, the filter research aid that all is absolutely necessary.For example, the aseptic suction filtration of culture medium, PBS, pancreatin in the cell cultivation process, degerming after the configuration of laboratory medicine or the like, we be unable to do without filter in a lot of researchs.
In order to practice thrift research cost, can select stainless steel filter usually at present, after sterilizing because this stainless filter can repeated multiple times be reused; And few easy workout part, no material consumption, operation and maintenance cost is low; Operational administrative is simple; This stainless steel filter generally includes a filter body, and its underpart connects a base, and filter body is provided with air inlet and filling opening.Yet in use also there is more shortcoming in this type filter: the fixing inconvenience of the height of ⑴ filter, and can't be according to the height change that connects the appearance bottle in using and the regulated at will oneself height; ⑵ do not have the volumetric measurement device, can't understand the volume of liquid in the filter owing to the material of stainless steel own, can not accurately judge the height at liquid level place in the filter; ⑶ do not have device for pressure measurement, can not accurately hold the pressure in the suction filtration process middle filtrator, if the excessive filter membrane that usually can cause of pressure breaks, do not play real filtration, and the too small rate of filtration that can cause again of pressure is often very slow, time-consuming or the like.
From the above, relating to a kind of filter more reasonable, easy, safe degerming is very important.
Summary of the invention
The goal of the invention of the utility model provides a kind of adjustable height, the controlled filter of P-V.
For reaching the foregoing invention purpose, the technical scheme that the utility model adopts is: a kind of filter comprises a filter body; Said body top offers air inlet and filling opening; Be combined with the liquid feeding flap with said filling opening, shown in the body bottom be connected with base, said base below offers leakage fluid dram; Said air inlet and leakage fluid dram place are provided with control valve respectively; Said body is provided with volume receptor, and nearly said air inlet place is provided with pressoreceptor, and said base has dismounting adjustable support structure.
Further technical scheme, said dismounting adjustable support structure comprises and base supporting leg outside bolted, outside said, is provided with the interior supporting leg that is slidingly matched with it in the supporting leg, nearly said outer supporting leg lower end is provided with the adjusting bolt that cooperates with interior supporting leg.
Further technical scheme, said interior supporting leg lower end is arranged with anti-sliding sleeve.
Further technical scheme, said body and base junction are provided with sealing ring.
In the technique scheme, said filter comprises a filter body, and the body top is provided with air inlet and filling opening; Cooperate on the air inlet to be provided with control valve and pressoreceptor, control valve opens and closes the input that is used to control external air pressure, and pressoreceptor can accurately be held the pressure in the filter body; Can prevent that hypertonia from causing filter membrane to break on the one hand, can prevent hypotony on the other hand, influence the liquid rate of outflow; Thereby save the working time, filling opening is used to add liquid to be filtered, and is combined with the liquid feeding flap; Body connects down base, and base is an infundibulate, at the oral area of base one screen pack is arranged; On screen pack, be placed with the miillpore filter that different experiments requires, the body bottom is connected through screw with base, can dismantle (so that changing filter membrane); Be lined with a resistant to elevated temperatures caulking gum packing ring at body and base connector place, in case liquid spills from the slit that is connected of body and base.Also be provided with volume receptor on the body, be used to understand the volume of liquid in the filter, understand liquid level; The base lower bolt connects outer supporting leg, and sliding in the outer supporting leg is provided with interior supporting leg, at the adjusting bolt that cooperates with interior supporting leg near the setting of outer supporting leg lower end; When regulating the filter height; Unclamp and regulate the bolt interior supporting leg that can stretch,, tighten again and regulate bolt and get final product until reaching suitable height; Lower end at interior supporting leg also is with anti-sliding sleeve, and the bottom of body is provided with the discharge that leakage fluid dram is convenient to filtered fluid.
Because the technique scheme utilization, the utility model compared with prior art has advantage:
1. the utility model is through being provided with pressoreceptor and volume receptor on filter body; Dismounting adjustable support structure is set in the base bottom; Make the height regulated at will according to the actual requirements of filter, and pressure and the volume in the controlled filter device accurately, control is convenient;
2. the utility model is simple in structure, and is easy to use, and cheap, is fit to promote the use of.
