The utility model discloses a kind of sample Minton dryer, this device comprises for nitrogen device, oil pump, oil bath heater, vacuum drying container, vacuum drying container is placed in oil bath heater, and be connected respectively with for nitrogen device and oil pump, described vacuum drying container comprises episphere container and lower semisphere container, two parts are coordinated by ground, and be fixedly connected with geometrical clamp, being equipped with sample bottle holder in described lower semisphere container, described sample bottle holder having the skewed slot for placing sample bottle.The advantage of this utility model is: the structure of vacuum drying container is detachable, is easy to picking and placeing of sample; Sample bottle holder designs skewed slot, makes sample bottle slant setting, avoid negative pressure and pass into the splashing that nitrogen causes sample in bottle; After passing into nitrogen, vacuum drying container is carefully split rear cap covers sample bottle, make sample long period stable preservation in a nitrogen environment.
Description
technical field:
The utility model relates to a kind of Minton dryer, particularly to the Minton dryer that a small amount of sample in laboratory heats.
background technology:
In chemical experiment, often will carry out vacuum drying treatment to sample, method conventional at present carries out vacuum drying treatment with vacuum drying chamber.
Vacuum drying chamber is as a kind of conventional Laboratory Instruments, be generally used for several grams even vacuum drying treatment of tens grams of relatively large samples, if sample only have one or two gram even less time, the waste that seems is processed with vacuum drying chamber, and in the lab, vacuum drying chamber is as the public instrument of one, different samples is placed in drying box and carries out vacuum drying treatment by different experimenters, long use, make drying box inside containing more organic solvent and drug residue, with it, vacuum drying treatment is carried out to sample, sample adsorption other impurity a small amount of may be caused, especially when sample is porous material, its adsorption capacity is stronger, cause adsorbing more impurity, thus affect sample purity.
When current laboratory needle carries out vacuum drying treatment to a small amount of sample (one or two gram even less), normal employing single neck bottle and oil bath pan mix oil pump to build an interim small size vacuum drying device again, sample is directly poured in single neck bottle, then oil bath pan is set to uniform temperature to heat single neck bottle, then with conduit single neck bottle is connected with oil pump and vacuumizes.But more difficult when the shape due to single neck bottle causes its sample thief, product originally just a small amount of after dry can not easily take out because be bonded at single neck bottle inwall and cause sample loss.In addition the preservation condition of some product requires higher, needs could preserve for a long time in inert gas (as nitrogen).
summary of the invention:
The technical problems to be solved in the utility model is to provide a kind of Minton dryer of detachable vacuum drying container, thus can easily pick and place and protect a small amount of sample after vacuum drying.
Concrete technical scheme of the present utility model is as follows:
A kind of sample Minton dryer, this Minton dryer comprises for nitrogen device, oil pump, oil bath heater, vacuum drying container (1), vacuum drying container (1) is placed in oil bath heater, and be connected respectively with for nitrogen device and oil pump, described vacuum drying container (1) comprises episphere container (5) and lower semisphere container (6), two parts are coordinated by ground, and be fixedly connected with geometrical clamp (2), sample bottle holder (3) is equipped with in described lower semisphere container (6), described sample bottle holder (3) is provided with the skewed slot (9) for placing sample bottle (4).
Further design of the present utility model:
The material of sample bottle holder (3) is polytetrafluoroethylene (PTFE).
The quantity of the skewed slot (9) on sample bottle holder (3) is 2.
Sample bottle holder (3) is spheric, and suitable with lower semisphere container (6) bottom.
Vacuum drying container (1) is connected respectively with for nitrogen device and oil pump through biexhaust pipe device.
compared with prior art, its remarkable advantage is the utility model:
The utility model provides a kind of Minton dryer carrying out effective vacuum drying treatment for a small amount of sample, avoid using the public vacuum drying chamber in laboratory to cause the contaminated situation of sample to occur, especially there is the sample of the porous material class of stronger adsorption capacity.
In the utility model, the structure of vacuum drying container 1 is simple; removablely be divided into upper and lower two parts; be convenient to setting-out and sampling; notch in addition on sample bottle holder 3 adopts inclined design; make sample bottle 4 one-tenth slant setting; avoid when carrying out nitrogen protection, negative pressure passes into the splashing that nitrogen causes sample in bottle.After passing into nitrogen, vacuum drying container is carefully split rear cap covers sample bottle 4, make sample long period stable preservation in a nitrogen environment.

Wherein: 1. vacuum drying container, 2, geometrical clamp, 3, sample bottle holder, 4, sample bottle, 5, episphere container, 6, lower semisphere container, 7, upper grinding port, 8, lower ground, 9, skewed slot.
detailed description of the invention:
By the following examples and further illustrate the utility model by reference to the accompanying drawings:
embodiment one:
As shown in Figure 1, sample Minton dryer of the present utility model is primarily of supplying nitrogen device, oil pump, biexhaust pipe device, oil bath heater and vacuum drying container 1 form, vacuum drying container 1 is placed in oil bath heater, and by being connected respectively with for nitrogen device and oil pump with biexhaust pipe device.
As shown in figs 2-4, vacuum drying container 1 comprises episphere container 5 and lower semisphere container 6, two parts are coordinated by upper grinding port 7 and lower ground 8, and is fixedly connected with (fixed folder structure signal is as Fig. 5) with geometrical clamp 2.The sample bottle holder 3 that material is polytetrafluoroethylene (PTFE) is equipped with in lower semisphere container 6, sample bottle holder (3) is spheric, and with lower semisphere container 6 bottom suitable, the height of sample bottle holder 3 is less than the height of lower semisphere container 6, and be directly placed on lower semisphere container (6) bottom.
Sample bottle holder 3 is provided with two groups of skewed slots 9 for placing sample bottle 4; can tilt to fix two sample bottles (object being designed to skewed slot is simultaneously; in the process of carrying out nitrogen protection; pass into nitrogen under negative pressure; if sample bottleneck upwards; under the direct impact of nitrogen, easily cause product to splash, cause loss of product).After drying completes, nitrogen is passed into vacuum drying container, container is carefully split rear cap covers sample bottle, thus obtain dry, free of contamination sample.
The course of work of the present utility model is as follows:
A small amount of sample is put into sample bottle 4, is placed in the skewed slot 9 of sample bottle holder 3 by uncovered for sample bottle 4, sample bottle holder 3 is put into lower semisphere container 6.In order to ensure the seal of vacuum drying container 1, apply appropriate vacuum ester at ground place.Fix after upper and lower hemispheres container closure with geometrical clamp 2, then vacuum drying container 1 is attached on oil bath heater, by shown in Fig. 1, device is connected.The rotary valve of biexhaust pipe device is rotated to the state of vacuumizing, then opens oil bath heater, start heating after suitable temperature is set, then open oil pump and vacuum drying container 1 is vacuumized.Sample is carried out to the vacuum drying of a period of time, after sample is by sufficient drying, closes oil pump, then the rotary valve of biexhaust pipe device is rotated to logical nitrogen state, after nitrogen is passed into vacuum drying container 1, gently split vacuum drying container 1, use cap covers sample bottle immediately.
