LABORATORY DEVICE FOR STUDYING ENVIRONMENT

摘要

FIELD: devices for use in study of environment, natural history and various sections of biology.;SUBSTANCE: in accordance to the invention, frontal wall of body is made of two parts, lower vertical part and upper inclined part, which form a bending rib. On the upper panel cradles are made for placement of hand-held magnifier, chemical glasses, pair of tweezers and cone, measuring ribbon, dosage spoon and a glass stick. One side of through groove of upper panel is parallel to side wall, and the other one is made at an angle to back wall. In the through groove, circular cradle is made for the cone and movable holder is mounted, sides of which are parallel to and interact with sides of through groove. Side walls of groove and side walls of holder interacting with them are made inclined. The holder is provided with a circular and a round through apertures. Circular aperture coincides with circular cradle of cone groove. Vertical plane of axes of cradles for chemical glasses coincides with vertical plane passing through connection of upper panel and inclined part of front wall. Niche for Petri dish is made in front wall in bending rib zone of front wall. Niche for tray is made in zone of through groove in lower part of back wall.;EFFECT: increase of comfort of usage and improved visualization of conducted experiments.;2 cl, 3 dwg
