Features

1. Outstanding infinity color corrected optical system

Infinity color corrected system, professional plan achromatic objectives and cutting-edge microscopy technology, provide microscopic images with high resolution, high definition and high contrast.
 

2. 22mm wide field
BS-2048 biological microscope can achieve a wide field of view range of 22mm under 10X eyepiece, which is more efficient and perfect for observation. Professional high eye point and wide field plan eyepiece can effectively correct edge distortion and chromatic aberration.
 

3. Rotatable viewing tube
Viewing tube with gemel group 360°rotation function , adjustable pupil distance, eye point height, for different height of the operator to provide a more flexible and comfortable experience.
 

4. Super large ceramic rackless stage
Double-layer mechanical stage, large arc shape, no angular design. The stage surface adopts ceramic paint process, high hardness, corrosion resistance. Damping-type double clips can be placed two slices at the same time, for inspection and comparative analysis.
 

 

5. Super endurance function

The body is equipped with a Type-C interface, which allows the microscope to use a portable battery as a power source. The microscope thus frees itself from dependence on power outlets, enabling easy use outdoors or in power outages. The body comes with a standard USB port, that allows the microscope to charge a phone or tablet.

                               Charge the microscope by the portable battery.                                                         Charge cell phones and tablets by the microscope.

6. With ECO energy-saving working mode

Build-in ECO function, no operation for 30 minutes, the system will automatically turn off and into the standby mode. Users can automatically wake up the light source by touching the dimming knob.
 

BS-2048 has a front LCD display, which displays the current lighting brightness, color temperature and magnification, so that the user can intuitively judge the working status and improve working efficiency.
At the same time, BS-2048 has the ECO function which gives a prompt whether to hibernate. Users can manually cancel, saving energy and improving user experience.
The hibernation waiting time is 5-60 minutes.

 

7. User-friendly design increases comfort and safety
BS-2048 is equipped with a secure handle for moving. Fully concealed locking design eliminates all sharp edges. Low hand coarse and fine coaxial focus system is ergonomically designed to give the user maximum comfort. There is a storage device at the back of the body to ensure the cleanliness, saving storage space and improving portability.
 

8. Brightness memory function
BS-2048 can be equipped with code nosepiece, able to remember the illumination brightness of each objective. Users can freely adjust the light source brightness of each objective and the system automatically remembers, not only to improve efficiency, but also to reduce visual fatigue.
 

 

9. Flexible manipulation of the LED fluorescent module
The innovative reflected LED fluorescence device greatly simplifies the operation process of the fluorescence microscope, making the microscopy experiment more simple, safe and efficient.
With light source brightness adjustment knob according to the characteristics of different specimens to set the appropriate illumination brightness. Rotating bright field / fluorescence switch knob, convenient for users to achieve easy conversion between transmitted light illumination and reflected fluorescence illumination.
 

10. Body power supply function
Built in 12V 1A transformer can directly charges the fluorescent illumination, easy to connect and safe to use.
 

11. Simple brightness adjustment knob and easy switching of bright field / fluorescent
By adjusting the knob, you can adjust the intensity of LED fluorescent lighting to get the required light.
According to the application needs, rotate the bright field / fluorescent switch knob, you can instantly achieve two kinds of observation switchover.
Switch to the fluorescence channel and use the LED fluorescence intermediate module to perform fluorescence observation for TB detection or immunofluorescence analysis and in vivo cell observation.
Switching to the bright field channel allows the use of transmitted light for routine pathological testing or laboratory observation.

 

Application

Various observations such as bright field, dark field and phase contrast can meet the needs of routine teaching and experimental observation.

Bright field observation
The professional plan achromatic objective, with the user of the Kohler illumination system, adjusts the image to the best condition by adjusting the aperture diaphragm and the field diaphragm. High-resolution, high-contrast microscopic images can be obtained whether at low or high magnification.
 

      Blood cell 20X bright field
 

                                                                                                   Male tapeworm transverse cleavage bright field
 

Phase contrast observation
It is suitable for observing samples with high transparency, such as cells, bacteria and other tiny, transparent objects in biological specimens.
 

                                      Oral epithelial cells 40X phase contrast                                                                                  Diatom 20X phase contrast

Dark field observation
Insert the dark field kit into the socket of the condenser and push the dark field diaphragm into the optical path to achieve simple dark field observation. Without replacing the special dark field condenser, dark field observation can be performed on and magnification objective in the range of 4X-40X, which can be used to observe protozoa, bacterial flagella spirochetes and other substances.
 

                                                                                                                                                                                         Watermill 20X dark field
