Product Description

 

BS-2043 Biological Microscope

Introduction

BS-2043 series microscopes are high quality biological microscopes, which are ideal choice for basic research and teaching experiments. With infinity color correction optical system and excellent compound eye illumination system, BS-2043 can get uniform illumination, clear and bright images at any magnification.
User-friendly design, simple and convenient operation, even students can easily operate. Maintains excellent reliability and durability, suitable for high-intensity use in the education area.

Features

1. Infinite color corrected optical system provides sharp and comfortable image
 

2. User-friendly design to increase comfort and safety

BS-2043 series microscope body adopts a smooth curve design, eliminating all sharp edges, rackless stage is optional. The frame has handles for easy handling. The microscope is stable, compact and beautiful. The charging adapter is built-in, saving laboratory space.
 

3. Compound eye illumination system provide uniform and comfortable illumination

BS-2043 innovatively adopts the compound eye illumination system to improve the contrast rate and effectively improve the illumination uniformity of the specimen surface. The brightness of the entire field of view is uniform. Even at the edge of the field of view, uniform and bright background brightness can be achieved under any magnification. Soft light, not harsh, not only the imaging effect is more ideal, but also can reduce the sense of fatigue, improve the observation experience and working efficiency. The LED light source is environment-friendly. Compared with halogen lamps, it consumes less energy and provides about 100,000 hours of sustainable lighting.

4. Continuous adjustable light intensity, easy to operate

The dimming knob is equipped on the right side of the microscope frame, which can easily adjust the illumination brightness by gently rotating. Continuous adjustable light intensity can effectively overcome the brightness jump phenomenon in traditional microscopes, and avoid the dizziness caused by instantaneous strong light.



5. Easy to store power cord
BS-2043 has a storage box on the back, which makes full use of the built-in space of the body and can be used to store the power cord conveniently. BS-2043 is designed to make your desktop clean and tidy.

6. With various optional accessories, easy to achieve observation methods of bright field, phase contrast, simple polarization, dark field and others
Bright Field Observation
The compound eye illumination system is equipped with professional plan achromatic objectives and has bright imaging. It can be used to observe cell structures and analyze plant slices.
Phase Contrast Observation
It is applicable to observe the specimens with high transparency, such as cells, bacteria and other small, transparent objects in biological specimens.
Simple Polarization Observation
It can judge substances with birefringence characteristic such as animals, plant cells and humoral crystals.
Dark Field Observation
There is no need to replace the special dark field condenser, as long as the dark field plates are inserted into the condenser and the diaphragm is switched, the dark field lighting can be realized.

From left to right, up to down is:
A. Endometrial Carcinoma 40X Bright Field
B. Adherent Cells 10X Phase Contrast
C. Pine Needles 10X Polarization
D. Sodium Glutamate Crystal 10X Dark Field

 

Applications

BS-2043 series microscopes are ideal instruments in 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.
