Abstract
The invention discloses a filter bag which is composed of an upper plastic film layer, a middle terylene filter cloth and a lower plastic film layer in a heat sealing manner on the periphery. An edge is preserved as an opening; and a space inside the terylene filter cloth is divided into two independent spaces. According to the technical scheme, the space inside the filter bag is divided into two independent spaces by the terylene filter cloth; one space is used for storing an object to be tested; eluate permeates the terylene filter cloth to enter the other space after extraction solution is injected for a period of time, so that the eluate can be directly measured to detect without soaking in a utensil; no particulate matter is doped in the eluate; the filter bag has the advantages of being convenient to use and operate, safe and reliable in detection, small in sample pollution, low in detection cost, etc.
Description
Technical field
The present invention relates to a kind of filter bag.
Background technology
In the prior art, solid-state or liquid determinand are detected, generally be on-the-spot pack after, in the laboratory or sensing chamber extract the part determinand and be immersed in the solution, treat that chemical substance is fully separated out after, measure lye and detect.Complex operation is measured the particle that also can mix in the liquid like this, and influence detects effect, also needs extra vessel to soak determinand, and easy generation of secondary pollution increases and detects cost.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this invention is to provide a kind of filter bag, easy to use, reduce sample contamination, reduce and detect cost.
In order to reach above-mentioned purpose, the technical scheme below the present invention has adopted:
A kind of filter bag is processed through peripheral Heat Sealing by upper strata plastic film layers, intermediate layer terylene filter cloth and lower floor's plastic film layers, and stays one side as opening, and said terylene filter cloth is divided into two independently spaces with spatial in the bag.
As preferably, said upper strata plastic film layers and intermediate layer terylene filter cloth are bonding near the opening part part.Be convenient to like this in a bag, put into food in the space, in another bag in the space through pipette extraction lye (only hold that pipette probe into get final product), avoid makeing mistakes, handled easily.
The present invention is owing to adopted above technical scheme, and the terylene filter cloth is divided into two independently spaces with spatial in the bag, and a space is used to deposit determinand; Pour into and extract a period of time behind the solution; Lye can penetrate the terylene filter cloth and get into another space, and the direct like this lye of just can measuring detects, and does not need vessel to soak; The particle that also can not mix in the lye has and uses advantages such as easy to operate, that detections is safe and reliable, sample contamination is little, the detection cost is low.
Description of drawings
Fig. 1 is structural representation of the present invention (opening part is overlooked);
Fig. 2 is structural representation of the present invention (facing).
The specific embodiment
Do a detailed explanation below in conjunction with the accompanying drawing specific embodiments of the invention.
Embodiment 1:
Like Fig. 1, a kind of filter bag shown in Figure 2; Process through peripheral Heat Sealing by upper strata plastic film layers 1, intermediate layer terylene filter cloth 2 and lower floor's plastic film layers 3; And staying one side as opening, said terylene filter cloth 2 is divided into two independently spaces 4,5 with spatial in the bag.
In the present embodiment, said upper strata plastic film layers 1 and intermediate layer terylene filter cloth 2 are local bonding through adhesive spots 6 near opening part.
It is emphasized that: above only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction; Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
Claims (2)
1. filter bag; It is characterized in that; Processed through peripheral Heat Sealing by upper strata plastic film layers (1), intermediate layer terylene filter cloth (2) and lower floor's plastic film layers (3), and stay one side as opening, said terylene filter cloth (2) is divided into two independently spaces with spatial in the bag.
2. a kind of filter bag according to claim 1 is characterized in that, said upper strata plastic film layers (1) and intermediate layer terylene filter cloth (2) are bonding near the opening part part.
