Technical Specification

 

For studying biological and geological specimens where focusing is not required particularly suitable in elementary schools.

Comprised of a large wooden tripod with screw-in angled legs, fitted with a plano-convex glass lens of diameter about 100mm. Magnifcation 2X. Height approximately 250mm. Prefocused.

For holding liquids and cultures for microscopic examination.
madefrom selected 1.5mm thick microscope slides(IxW),75x25mm with ground edges.Spherically polished cavities are 13mm diameter with 0.5-0.6mm depth.

For introductory biology and histology work. Suitable for slicing micro thin sections from 0.01 mm (10 microns). Consists of a piston screwed into a tube whose free end is fixed into a flat plate serving as a stage. The knurled head at the bottom of the instrument moves the piston up or down the central tube when rotated. The specimen is fixed on the flat top of the piston and sections are cut by drawing a razor over the upper flat surface of the instrument. Equipped with a clamping mechanism for objects of different shapes. Graduated in 10-micron (0.01mm) steps. Advances 500 microns (0.50mm) for each complete turn. Supplied with a single edge tempered steel razor knife. Packed in a velvet lined wooden case.

For standard scalpel handles No. 3 and No. 4. Made of surgical steel, sterile and individually packed in aluminium foil. Differ in size and curvature. Pack of 10 blades.

For junior high students and young hobbyists.

Comprised of a horseshoe type base, vertical monocular body inclinable through 45º, a metal stage 100 x 100mm with fixed clips, rack and pinion focusing and the microscope tube having standard threads to objective. Other important features are:

As a replacement for the reflector for the above microscopes.

For elementary microscopes.
