BS-2091
BS-2091F
Introduction
BS-2091 Inverted Biological Microscope is a high-level microscope which is specially designed for medical and health units, universities, research institutes to observe cultured living cells and tissues. With innovative infinite optical system and ergonomic design, it has excellent optical performance and easy to operate features. The microscope has adopted long life LED lamps as transmitted and fluorescent light source. The microscope has smooth and comfortable operation, intelligent energy conservation system, it could be the best assistant for your work.
Feature
1. Ergonomic viewing head.
360° rotatable viewing head with 50mm-75mm adjustable inter-pupillary distance, the eye-point can be raised 34mm directly by rotating the tube at 65mm IPD, more convenient and faster than traditional way.
Safe and efficient LED.
Both the transmitted and EPI-fluorescent illumination have adopted LED lamps, energy saving and long-lasting, low heat, the illumination is safe and stable. X-Y mechanical stage and various specimen holders are available.
Intelligent ECO system
Based on the concept of energy conservation and environment protection, BS-2091 has been designed with ECO system. The illumination power can be automatically on or off through infrared induction.
Marking objective is available.
New designed "marking objective" with ink inside for marking the target, it is very practical and effective to extract the target cell when observe and culture the living cells.
Smart phone connection kit.
Specially designed kit which can be inserted into the eyepiece tube for combining a smart phone on a microscope, keep record on time by taking photo or video.
Professional LED reflected fluorescence illumination system.
BS-2091F is equipped with a professional LED reflected fluorescence illumination system, and can be equipped with high-quality fluorescent objective lenses and fluorescent filters, which can meet various research tasks.
(1) The fluorescence module has 4 positions. The standard configuration is Blue and Green fluorescence filters. Up to 3 sets of fluorescence filters can be installed.
(2) Using high-brightness narrow-band LED lamps as the light source, the service life can reach more than 50,000 hours, which is safe, efficient, does not need to be replaced, and is more environmentally friendly and energy-saving.
(3) BS-2091F inverted fluorescence microscope has added fluorescence filter status display, through the built-in sensor, the currently used fluorescent filter is displayed in front of the microscope, making research work more convenient and efficient.
Long working distance infinite plan achromatic objective and fluorescent objectives are available.
Long working distance infinite plan and phase contrast achromatic objective
Long working distance fluorescent infinite plan and phase contrast achromatic objective
Infinite plan Relief phase contrast achromatic objective
Application
BS-2091 inverted microscope 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.
