DENDROLOGY

Detailed explanation-1: -In a herbarium, plants are dried in a forced-air plant drier that approaches temperatures of 100°C. Presses are placed in the drier in such a manner that the hot air can be blown up through the cardboard corrugates to help dry the plants more evenly.

Detailed explanation-2: -Specimens look best if dried by having air move over them. This is why sheets of corrugated cardboard are used in the press. Put the whole press in a warm, airy place until the specimens are completely dried out. The air temperature should be no more than 100°F or thereabouts.

Detailed explanation-3: -Safety and Disposal Considerations in Specimen Collection There are four steps involved in obtaining a good quality specimen for testing: (1) preparation of the patient, (2) collection of the specimen, (3) processing the specimen, and (4) storing and/or transporting the specimen.
