Abstract
The utility model belongs to a micropore filter film filter. The micropore filter film filter comprises an upper cup with an injector interface and a seal ring, and a receiving bottle positioned at the lower part of the upper cup; the receiving bottle comprises an interface matched with the upper cup, a micropore filter film positioned at the interface, a perforated screen plate, a sample filtering cavity and a liquid outlet; a sand core filter plate is arranged in the interface of the upper cup; a sand core is of a disc-like ceramic wafer. The connection position between the upper cup and the receiving bottle is assembled by adopting a glass dull polishing port. The sand core filter plate is additionally arranged in front of the film of the micropore filter film filter for being used as primary filtering, so the leakage phenomenon of the micropore filter film caused by high-concentration particles is reduced; at the interface structure, the glass dull polishing port is used for replacing a screwing port, so the operation is more convenient and the possibility of the damage to the filter film is reduced.
Description
Technical field
The utility model patent relates to a kind of filter, is specifically related to a kind of nuclepore membrane filter.
Background technology
When HPLC detects, sample need pass through micro porous filtration.Existing filter mainly contains two kinds: disposable aspiration needle filter and film changeable syringe needle filter.The former is easy to use, but frequency of utilization is when high, and cost is larger; The latter is economical and practical, has relatively high expectations but change membrane operations.For containing the higher sample of granularity, all likely can there is the phenomenon that stifled film leaks film in both.
Summary of the invention
The utility model is mainly for the problem in above-mentioned technology, and a kind of nuclepore membrane filter is provided, and this nuclepore membrane filter adds a core as initial filter before miillpore filter, reduces the leak stopping phenomenon causing because granule density is high; Structurally, replace and screw interface with glass frosted interface, make more convenient operation, reduce the possibility of filter membrane breakage simultaneously.
The purpose of this utility model is mainly achieved by following proposal: a kind of nuclepore membrane filter, comprise upper cup and the receiving flask that is positioned at its underpart with syringe interface and sealing ring, described receiving flask comprises the interface coordinating with upper cup, the miillpore filter that is positioned at interface, slotted plate, sample filter back cavity and liquid outlet, in the interface of described upper cup, be provided with a core filter plate, described core is discoid potsherd.
Core filter plate of the present utility model is changeable type, and different core filter plates is designed with different apertures according to the solid of the different size rank of required filtering (comprise raw sediment, gelatinous precipitate, thin sediment, even germ etc.).
As preferably, the junction of described upper cup, receiving bottle adopts glass frosted mouth to assemble.
Compared with prior art, the beneficial effects of the utility model are: this nuclepore membrane filter adds a core filter plate as initial filter before film, reduce the leak stopping phenomenon of the miillpore filter causing because granule density is high; On interface structure, replace and screw interface with glass frosted interface, make more convenient operation, reduce the possibility of filter membrane breakage simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Shown in Fig. 1: 1. syringe interface, 2. cup 4. receiving flask 5. interface 6. miillpore filter 7. slotted plate 8. sample filter back cavity 9. liquid outlet 10. cores on sealing ring 3..
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail; but be not limited to following embodiment; the technical staff of same area can propose other embodiment in the technical solution of the utility model framework, but these embodiment include in protection domain of the present utility model.
As shown in Figure 2, a kind of nuclepore membrane filter, comprise upper cup 3 and the receiving flask 4 that is positioned at its underpart with syringe interface 1 and sealing ring 2, described receiving flask comprises the interface 5 coordinating with upper cup, the miillpore filter 6 that is positioned at interface, slotted plate 7, sample filter back cavity 8 and liquid outlet 9, in the interface of described upper cup, be provided with a core 10, described core is discoid potsherd.The junction of wherein said upper cup, receiving bottle adopts glass frosted mouth to assemble.This nuclepore membrane filter adds a core as initial filter before film, reduces the leak stopping phenomenon of the miillpore filter causing because granule density is high; On interface structure, replace and screw interface with glass frosted interface, make more convenient operation, reduce the possibility of filter membrane breakage simultaneously.
The above-mentioned specific embodiment is used for the utility model of explaining; rather than the utility model is limited; in the protection domain of spirit of the present utility model and claim, any modification and change that the utility model is made, all fall into protection domain of the present utility model.
Claims (2)
1. a nuclepore membrane filter, comprise with the upper cup (3) of syringe interface (1) and sealing ring (2) and be positioned at the receiving flask (4) of its underpart, described receiving flask comprises the interface (5) coordinating with upper cup, the miillpore filter (6) that is positioned at interface, slotted plate (7), sample filter back cavity (8) and liquid outlet (9), it is characterized in that, in the interface of described upper cup, be provided with a core filter plate (10), described core is discoid potsherd.
