Description

BS-2044B Biological Microscope

Introduction

BS-2044 series microscopes are high quality biological microscopes, which are specially designed for biological and medical research and teaching experiments for colleges, universities, laboratories and related institutes. With infinity color correction optical system and excellent Koehler illumination system, BS-2044 can get uniform illumination, clear and bright images at any magnification. These microscopes can be used for teaching experiments, pathological examinations and clinical diagnosis. With outstanding functions, excellent cost performance, easy and comfortable operation, BS-2044 series microscopes present over expected and splendid micro images.

Feature

1.Infinite Color Corrected Optical System provides sharp and comfortable images.

2.Wide-field high eye-point eyepieces and plan achromatic objectives make the effect of fluorescence observation more perfect.

3.Outstanding appearance design and ergonomics structure design, long time use without feeling tired.

4.With the design of security lock and safe limits, it is much more secure, stable and can be kept for long.

5.Various microscopic examinations can be fulfilled, such as brightfield, dark-field, phase contrast, fluorescence, simple polarizing and so on.

6.LED fluorescence excitation illumination, breaking through the traditional type, is more stable, low radiation and long working life. Special fluorescent filters for tuberculosis examination is available.

Application
BS-2044 series biological microscopes are ideal instruments for biological, pathological, histological, bacterial, immune, pharmacological and genetic fields. They can be widely used in education, medical and sanitary establishments, such as schools, hospitals, clinics, laboratories, medical academies, colleges, universities and related teaching labs and research centers.
