Description
Technical field
It the utility model is related to experimental provision technical field, and in particular to a kind of core filter.
Background technology
Core filter uses the high-quality glass material of ultrahard, and uniform wall thickness, bubble-free, glass clear transparent, flow is fast,
Pressure-resistant and sealing property is very good, and dimensions meets international standard, is available for autoclave sterilization to use.It is widely used in chemistry
Analysis, sanitary inspection, environmental monitoring, biological products, Products Industry, scientific research etc., filter out particulate and bacterium.Such as oil
Field water filling, suspended sediment concentration, membrane filtration factor, particle diameter and sterility test are analyzed, cultivate bacterium aseptic filtration.Thermal sensitivity medicine
The aseptic filtration of thing, reach sterile purpose, and the analysis such as aviation kerosine, hydraulic oil, high purity reagent, water quality measure.
Existing core filter includes cylinder type glass funnel, core filter, triangle filter flask and clip composition, its
The specification of intermediate cam filter flask is usually 250-5000 milliliters, and triangular design causes bottom area big, due to that may cause sample
Product loss is excessive, it is difficult to the filtering applied to less than 50 milliliters a small amount of samples.
The content of the invention
The utility model is exactly a kind of filter for the offer that solves the above problems, and the device can reduce filter process
The loss of middle solution.
A kind of core filter, as Figure 1-3, including cylinder type glass funnel（1）, core filter（2）, triangle filter
Bottle（3）And clip（16）, core filter（2）Side wall is provided with vacuum interface（6）, bottom is provided with core discharging tube（5）；Its feature exists
In setting up liquid-holding pipe（7）, liquid-holding pipe（7）Spout part is provided with the first portion protruding outside（8）, the first portion protruding outside（8）External diameter
More than triangle filter flask（3）Bottleneck（4）Internal diameter, less than bottleneck（4）External diameter, liquid-holding pipe（7）Positioned at triangle filter flask（3）It is interior
Portion, core discharging tube（5）End be less than the first portion protruding outside（8）.
Triangle filter flask（3）It " can hold in the palm " and live liquid-holding pipe（7）；Core discharging tube（5）End less than the one protuberance of outside
（8）, ensure that filtered sample flows directly into liquid-holding pipe（7）In, it is possible to achieve the separation for a small amount of sample.
Beneficial effect
The utility model ensure it is original can carry out a large amount of solvent filters on the premise of, realize for a small amount of sample
Filtering function.
