Specimens Specimens should be placed on biological hood number too large to store homemade glass Cabinet, to moisture, corrosion, dust, insects and rodents. Within the cabinet with silica gel or lime (with two layers of gauze wrap) desiccant plant specimens soaked with insecticide formulations camphor mildew (wrapped with gauze). Specimens not long bare cupboard on top of dust. New stuffed specimens do not dry into biological hood. Fumigant can eradicate pests in the spring, the specimen placed in a sterile box Xinxiang plant specimens price, put the dishes in the box, put the bowl above the bowl put sulfur, iron bars put on the bowl, lit sulfur Xinxiang plant specimens factory sealed cover. Two days later, open the lid, took into biological specimens stored in cabinets. Prepare specimens commonly used preservative fixed drug plant specimens, What are the advantages? Glycerol: glycerol scientific name, is a colorless, transparent, odorless, viscous liquid with a sweet. Advantages: a mixed preservative fixative, glycerin is a good selection of drugs. Use of its corrosion resistance, moisture and inorganic salts of certain drugs to dissolve the special forces, which dubbed the solution is relatively stable, easy to dry specimens are fixed, more flexible, connective tissue is slightly transparent. 2. The glycerin can be adsorbed in admixture with a drug (such as formaldehyde, ethanol, phenol, etc.), and remain in the specimen inside surface, so that these drugs less volatile and loss, to enhance the effect of these drugs preservative fixed, improve anti-mold capability. Glycerin can mitigate volatile formaldehyde, reducing irritating odor, improve the teaching and learning environment. Glycerol having hydrophilic and dewatering, and as the concentration increases strengthened. High concentrations of glycerol enables organizations to protein denaturation, played antiseptic effect, but also make organizational severe dehydration, specimens shrink dry. Glycerol dehydration antiseptic effect, can be made semi specimens; glycerol transparent effect, can be made translucent specimens.
