Product
description
One,
use and characteristics
The microscope is widely
used in biology, bacteriology,
histology, pharmaceutical research, in
medical clinical trial is conducted, in
the school laboratory for teaching
purposes.
Apparatus adopts a
lifting Abbe condenser group, so that
the light regulating range greater.
Planetary type coaxial coarse, micro
focus device, so that the focus is
comfortable and can be used for fine
tuning; a reading scale double
mechanical moving platform, its coaxial
longitudinal, transverse regulating
handwheel, easy to operate.
