Description
Technical field
The present invention relates to a kind of chemical apparatuses, be specifically related to a kind of anhydrous and oxygen-free solid phase extraction elutriator, belong to chemical apparatuses apparatus field.
Background technology
In chemical research, often will use various solid phase extraction or absorption, but but do not have special washing device during these extracts of wash-out, especially in the operation of needs anhydrous and oxygen-free or when having special requirement to filter paper, traditional Buchner funnel combination is difficult to reach requirement.Such as, when thin-layer chromatography prepares sample, sample is usually more valuable and stability unknown, need the amount of wash-out often little again, easily occur that silica gel is filtered thoroughly with conventional instrument suction filtration and affect nuclear-magnetism result, and usually existing following not enough: during suction filtration, filter paper is difficult to closely easily leak material, the easy crystallization of much filtrate with funnel laminating, is difficult to take out, Buchner funnel inside is not easy to clean up, cannot the problem such as omnidistance anhydrous and oxygen-free operation.For solving this series of problem, the wash-out of easy solid extract, be badly in need of at present improving such device.
Summary of the invention
The object of the invention is to provide a kind of Novel anhydrous anaerobic solid phase extraction elutriator, makes the wash-out of solid phase extraction (absorption) thing become very convenient.
For realizing the object of the invention, Novel anhydrous anaerobic solid phase extraction elutriator of the present invention is emitted by spiral, cylinder, V-type funnel form, and it is characterized in that, the upper and lower two ends of cylinder are respectively equipped with taenidium, and spiral emits and is fixed on cylinder upper end by taenidium; V-type funnel upper end wall body is provided with chimb, is provided with groove in chimb lower wall; Spiral running-on upper end is fixed on cylinder by the taenidium of cylinder, and spiral running-on lower end connects V-type funnel by V-type funnel chimb, and V-type funnel is connected as a single entity by groove and cylinder, and V-type funnel lower end is provided with piston.And be equipped with glass sieve plate (or tetrafluoro sieve plate) on V-type funnel groove, a ring packing rubber cushion respectively established up and down by glass sieve plate (or tetrafluoro sieve plate), and filtering bodies is positioned between annular rubber cushion and glass sieve plate (or tetrafluoro sieve plate).
Spiral emits can be with syringe connector.Filtering bodies can be filter paper, filter cloth, filter membrane etc.Piston can be rotary-piston.
Spiral emits, cylinder, V-type funnel can adopt glass, polytetrafluoroethylene (PTFE) or polyester material.
Spiral emits for inflation and sealing, and cylinder is used for loaded material, and spiral running-on is for connecting cylinder and funnel, and ring packing rubber cushion is used for fixing filter course, and filtering bodies is used for filtering, and piston can be glass or polytetrafluoroethylene (PTFE) material, for controlling blowing.
Novel anhydrous anaerobic solid phase extraction elutriator of the present invention can use press filtration and suction filtration two kinds of filter types; the filtering bodies such as filter paper, filter cloth, filter membrane can be loaded; filtering bodies and funnel are fitted closely can not leak material; gas shield can be carried out easily, mode of oscillation can be used to mix, wash.And all parts in device can be unpicked and washed easily, there is no dead angle, and the glass sieve plate (or tetrafluoro sieve plate) being difficult to clean can be changed, there will not be the mutual pollution between product, be particularly useful for the experiment that anhydrous and oxygen-free operates or filter paper had to special requirement.
