The Steindorff® S-274 LED Fluorescence Microscope Series comes equipped with wide field eyepieces, epi-fluorescence attachment, siedentopf binocular or trinocular viewing head, and infinite plan achromatic objectives. The epi-fluorescence attachment utilizes an LED light source which has a longer life span than the standard mercury lamp. The S-274 is used to study the absorbing, transportation, chemicals distribution and positioning in cells. It is widely used in disease examination, immune diagnosis and life science areas.
- Excellent fluorescent image with infinitive optical system.
- LED illumination with 50,000 hours life span.
- 465-476nm excited wavelength with high SNR.
- Convenient to use, no need warm-up.
