Description
Technical field
The present invention relates to the preparation method of preparation of specimen, and in particular to a kind of preparation method of plant colouring sample.
Background technology
In the world, plant easy browning, the leaf of burn into sample, flower, fruit etc. during using and preserving is also easily de-
Fall, the exsiccata being routinely fabricated to in-convenience in use.And the sample of soak is volatile due to preserving liquid, also have room air
Niff, and preservation liquid need to be often changed, also it is unfavorable for visiting and learning.Chinese patent CN1214202A discloses a plant
Thing specimen with covered color-protecting film preparation method, it is handled by plant colouring and then will protected the smooth pressurization of color plant, drying, will protect color
The taking-up from keeping color agent of treated above-mentioned plant is rinsed 1~2 hour with running water, and color plant will be protected after rinsing well and takes out folder
It is put into rice paper and is pressed with electric iron pressure, is put into again after pressure ironing is whole in dry rice paper and continues to suppress, until being completely dried, pressure is pressed
When electric iron temperature can be transferred to 50~100 DEG C；This method by electric iron high-pressure drying is not easy to operate, and time-consuming longer,
Pressure is easily burned during pressing, and preparation process is dangerous.
The content of the invention
There is provided a kind of preparation side of new plant colouring sample in order to solve the problem of prior art is present by the present invention
Method, this method is simple, and safety coefficient is high.
A kind of preparation method of plant colouring sample, comprises the following steps：
1) sample process：The plant collected is rinsed well with running water standby；
2) sterilize：By step 1) in clean plant be put under uviol lamp, sterilize 20~40min；
3) prepare and protect chromogen liquid：Copper acetate is added in glacial acetic acid, and saturated acetic acid copper guarantor's chromogen liquid is made；
4) plant colouring is handled：Copper acetate guarantor's chromogen liquid is diluted to copper acetate keeping color agent with pure water, will have been diluted
Copper acetate keeping color agent pour into heating vessel in heating the plant that need to protect color is put into 90~100 DEG C, then the vinegar heated
In sour copper keeping color agent, continue to be heated to after vegetation color all takes off and untill recovery；Temperature control is at 90~100 DEG C, heating
Time is 20~40min, and its specific heat time will be depending on different plants；
5) protect color plant and remove loose colour：The taking-up from keeping color agent of the treated above-mentioned plant of color will be protected and rush 1~2 with running water
Hour, remove loose colour；Color plant will be protected after rinsing well to take out, and water purification part is blotted with blotting paper；
6) microwave drying：The sample after color will be protected, change in dry blotting paper, be put into small-sized specimen holder, be put into micro-
3~4min of microwave treatment in ripple stove, the specific time is adjusted according to the number of sample；
7) plant specimen with covered color-protecting film is made：The good guarantor color plant of microwave drying is placed on ivory board, after pressing, is put into
Card-protecting film plastic packaging is used in plastic packaging machine, that is, obtains qualified plant colouring film sample.
Preferably, the ultraviolet wavelength is preferably 240~280 nanometers, more preferably 254 nanometers.
Preferably, step 2) in uviol lamp sterilizing time be 30min.
Preferably, the step 3) in copper acetate protect chromogen formula of liquid weight ratio be：Glacial acetic acid:Copper acetate=4:1.
Preferably, the step 4) in heating container be selected from glass container, rustless steel container or ceramic vessel, it is more excellent
Elect ceramic vessel as.
Preferably, the step 4) in copper acetate keeping color agent formulation weight ratio be：Copper acetate protects chromogen liquid:Pure water
=2:98.
Preferably, the step 6) microwave drying process in control micro-wave oven power in 650W-1050W, it is more excellent
Elect 700W-800W as.
Preferably, the step 7) in ivory board thickness be 0.3~0.5 millimeter, the thickness of the card-protecting film is 0.16
~0.20 millimeter, during the Plastic Package card-protecting film, temperature control is at 160~180 DEG C, more preferably 170 DEG C.
Microwave current stove is primarily used in culinary art, and its principle mainly uses food to absorb microwave energy in microwave field
And make the cooking apparatus of conducting self-heating.Generally, microwave is a kind of high-frequency electromagnetic wave, and itself does not produce heat,
Grow on trees microwave in universe, nature, but there is the microwave of nature, because scattered do not concentrate, therefore can not heat food.It is micro-
Ripple stove is, using its internal magnetron, to convert electric energy into microwave, food is penetrated with 2450MHz frequency of oscillation, when micro-
When ripple is by food absorption, the polar molecule (such as water, fat, protein, sugar) in food is to be attracted to each second 2,400,000,000 5 thousand
The speed quick oscillation of ten thousand times, the macro manifestations of this vibration are exactly that food is heated.When on microwave radiation to food, food
Always contain a certain amount of moisture in product, and water is that (the positive and negative charge center of molecule is not deposited even in external electric field by polar molecule
When be also misaligned) composition, the orientation of this polar molecule will change with microwave field.Due to the polarity of food reclaimed water
This motion of molecule, and the interaction between adjacent molecule, generate the phenomenon of similar friction, raise water temperature, therefore,
The temperature of food also just rises, the food heated with microwave, because being also heated inside it simultaneously, makes whole object heated equal
Even, programming rate is also fast.Microwave applications in the drying of sample, are heated evenly it by the present invention, and rate of drying is fast, green energy conservation
Environmental protection, safety coefficient is high.
The present invention uses ultraviolet sterilization before preparation of specimen, and ultraviolet has very strong sterilizing power, can kill various bacteriums
Brood body (including tubercle bacillus), fungi, virus, and the bacterial spore stronger to physics, chemokines resistance, extension mark
This holding time；The sample that the present invention is protected after color using microwave drying simultaneously, is heated evenly it, and rate of drying is fast, green section
Can environmental protection；The plant specimen prepared through present invention process is colour-fast, and color Chang Xin is not old, does not roll over and does not wrinkle, be hardly damaged, favorably
In the interest of training student, be conducive to carrying out education activities；The present invention has easy to use, cost is relatively low, safety coefficient is high etc.
Advantage, can be widely applied to the every field of preparation of specimen.
