BS-2190B Inverted Biological Microscope
BS-2190B
Introduction
BS-2190B series Inverted Biological Microscopes are specially designed for observation of cell tissues culture and can be used to observe cell growth processes, tissue contours and internal structures. Optional professional fluorescence attachment can be used to observe autofluorescence phenomena in cells, fluorescence transfection, protein transfer and other fluorescence phenomena of biological cells.
With innovative infinite optical system and ergonomic design, the microscopes have excellent optical performance and easy to operate features. The microscopes have smooth and comfortable operation, they could be used for medical and health units, universities, research institutes to observe cultured living cells and tissues.
Feature
1. Color corrected infinite optical system, excellent optical performance and great images.
2. Application of high-contrast and low chromatic phase contrast observation, access to detailed examination of internal structure of the cells.
3. Supply long working distance and high N.A. objectives to get the flat and clear images.
4. Koehler Illuminator.
(1) With iris diaphragm, adjusted by rack and pinion, convenient to adjust and remove the condenser.
(2) The condenser bracket can be rotated, facilitate the replacement of the dish, and suitable for a variety of sample containers.
(3) With precise orientation and locking device.
5. Well-designed body structure, steady and reliable and better anti-vibration performance.
6. Low position coaxial coarse and fine adjustment, ergonomic design.
7. Professional vertical fluorescent technology, to get clear and bright fluorescent images.
8. Long working distance infinite plan achromatic objective, phase contrast objective and fluorescent objectives are available.
Long working distance infinite plan and phase contrast achromatic objective
Long working distance fluorescent infinite plan and semi-APO phase contrast objective
Application
BS-2190B series inverted microscopes can be used by medical and health units, universities, research institutes for observations of micro-organisms, cells, bacteria and tissue cultivation. They can be used for continuous observation of process of cells, bacteria grow and divide in the culture medium. Videos and images can be taken during the process. These microscopes are widely used in cytology, parasitology, oncology, immunology, genetic engineering, industrial microbiology, botany and other fields.
