(1) Dustproof
Dust is very destructive to specimens. On the one hand, very small dust contains minerals, wear ingested on the specimen, on the other hand, dust contains moisture, some dust becomes an active chemical medium, directly destroying the specimen. Dust often carries microbes and eggs, causing direct damage to the specimen. So the specimen chamber and specimen should be often dusted, keep neat and clean.
(2) Insect control
The skin and the rint swashes are common insect species that decay into the specimen, and they are extremely badly damaged to the specimen. Usually plasticized specimens are used to remove insects from a large number of camphor blocks or camphor pills. Camphor is volatile and is replaced regularly.
(3) Anti-mold anti-corrosion
Spring air humidity is very large, specimens easy to moisture, long mold. Special attention should be paid to the specimen room moisture and timely ventilation, to achieve moisture and mold prevention purposes. For immersion specimens, the preservation liquid volatiles quickly, to often add the preservation liquid, so as not to expose the preservation liquid and dry, and regularly replace the new preservation liquid, at least every year must add the preservation liquid twice. Preparation of the preservation liquid: Formarin is 8% to 10% and alcohol is 75%.
(4) Maintenance and remedial measures in exceptional circumstances
Animal specimen manufacturers immersed specimens have been placed for a long time, specimens are prone to aging. If the preservation liquid appears cloudy, the plasticized specimen can be filtered by the preservation fluid, the turbidity removed or used to add a small amount of polymerization agent; Plasticized specimens for the moldy specimens, with a small brush to a small amount of chloroform, after a light brush to clean dry, if necessary to deal with the place coated with a varnish, can maintain the original color of the specimen. Stripped specimen skin dry water appear cracks, can be used glycerin, soap, and cream each 1/3 mixed into a solution, and then coated in the crack, and so on the skin is completely moist, the crack will be sewn, but pay attention to the specimen shaping.
