Abstract

The utility model discloses a totally closed assembled low-pressure molecular sieve which relates to a structure of the molecular sieve. The totally closed assembled low-pressure molecular sieve comprises a vacuum drier (4) which is internally provided with upper and lower elastic clamping rods (9). Both ends of the elastic clamping rods (9) are fixedly arranged on left and right inner walls of the vacuum drier (4). The upper elastic clamping rod (9) is provided with a test tube (1), while the lower elastic clamping rod (9) is provided with a drying bottle (3). The opening of the test tube (1) is downward and the test tube extends into the drying bottle (3). A dialysis bag (2) is sleeved at the opening of the test tube (1). An end socket (5) connected with a bend (6) is arranged at the opening above the vacuum drier (4). The totally closed assembled low-pressure molecular sieve provided by the utility model solves the problems in the prior art that a protein removing device is labor and time consuming, high in cost, pollutive, large in error in the extraction process, unstable in structure and the like.

Description

Totally-enclosed collective low-pressure molecular sieve

Technical field

The utility model relates to a kind of molecular sieve structure.

Background technology

Molecular sieve is the cancellated natural or artificial synthetic chemical substance of tool, as cross-link dextran, zeolite etc., when as chromatography media, can carry out the classification separation to mixture by molecular size.

At present, in medical experiment, radiation trader analytic approach is that a species specificity is good, the detection method that sensitivity is high, but blemish in an otherwise perfect thing is the experiment that part is measured the molecule hormonal substance of low concentration, before measuring, a set of numerous leaching process is often arranged, purpose is to remove impact and does the former protein that does the body combination.Prior art remove phi protein exist take a lot of work, time-consuming, cost is high, has pollution, extraction process to have larger error.And the existing apparatus structural instability, the course of work is unreliable.

The utility model content

The utility model provides a kind of totally-enclosed collective low-pressure molecular sieve, solved prior art remove phi protein exist take a lot of work, time-consuming, cost is high, has pollution, extraction process to have larger error, the problems such as structural instability.

For addressing the above problem, the utility model adopts following technical scheme: totally-enclosed collective low-pressure molecular sieve, comprise vacuum desiccator 4, be provided with upper and lower two-layer elasticity clamping bar 9 in vacuum desiccator 4, elasticity clamping bar 9 two ends are fixed on the inwall of vacuum desiccator 4 left and right sides, above test tube 1 is installed on elasticity clamping bar 9, on lower floor's elasticity clamping bar 9, drying bottle 3 is installed, test tube 1 port downwards and be inserted in drying bottle 3, is set with bag filter 2 at test tube 1 port; Above vacuum desiccator 4, opening part has plug 5, and on plug 5, bridge piece 6.

Totally-enclosed collective low-pressure molecular sieve of the present utility model, can be applied in medical experiment, is a kind ofly can remove impact and do the former device that does the protein of body combination.The utility model utilizes the pressure differential of inner air and outer air, and by sample pressure filtration, and filtering material adopts the very little dialysis mould in aperture, reaches by sized molecules in sample separately.The utility model is realized synchronous molecular filtration process, owing to having removed prior art fierce mechanical shaking extraction process repeatedly from, removed from and used harmful organic solvent, operating procedure has greatly been simplified, pollution abatement, guarantee operating personnel's personal safety, and making power consumption low, equipment attrition is little, with low cost, the saving of labor, save time, error is little.

The utility model adopts fixedly test tube of elasticity clamping bar, and the elasticity clamping bar is fixed on the sidewall of vacuum tank, elasticity clamping bar Stability Analysis of Structures, and the test tube of taking is convenient, and the course of work is safe and reliable.

Fig. 2 is the top view of elastic clip.

Symbol description in figure: test tube 1, bag filter 2, drying bottle 3, vacuum desiccator 4, plug 5, bend pipe 6, manage 7, water 8, elasticity clamping bar 9, sample 10, filter liquor 11.

The specific embodiment

Below with best embodiment, the utility model is described in detail .

As shown in Figure 1, totally-enclosed collective low-pressure molecular sieve, comprise vacuum desiccator 4, be provided with upper and lower two-layer elasticity clamping bar 9 in vacuum desiccator 4, elasticity clamping bar 9 two ends are fixed on the inwall of vacuum desiccator 4 left and right sides, above test tube 1 is installed on elasticity clamping bar 9, on lower floor's elasticity clamping bar 9, drying bottle 3 is installed, test tube 1 port downwards and be inserted in drying bottle 3, is set with bag filter 2 at test tube 1 port; Above vacuum desiccator 4, opening part has plug 5, and on plug 5, bridge piece 6.

Bend pipe 6 connects vavuum pump by pipe 7, bled, make the interior generation negative pressure of vacuum desiccator 4, then clamp the mouth of pipe and break away from vavuum pump, whole device is moved on in refrigerator, in test tube, sample in being exuded to gradually the drying bottle 3 of inferior vacuum environment under inner air tube pressure and negative pressure in bag filter (film), form filter liquor, the small-molecule substance that is less than the dialysis membrane aperture is taken out of, the macromolecular substances such as protein still are trapped in bag filter, while Deng liquid, reaching setting, take out test tube, can be measured.

Finally it should be noted that: obviously, above-described embodiment is only for the utility model example clearly is described, and is not the restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.And the apparent variation of being amplified out thus or change are still among protection domain of the present utility model.
