Levenhuk 400B Optical Microscope
Levenhuk 400B is a binocular laboratory microscope for working with biological samples. This optical device was created specifically for microbiologists, biochemists, veterinarians and doctors. The microscope allows you to conduct professional research at magnifications from 40 to 1000 times. You can use the bright field method and oil immersion. The swivel head can be rotated 360°, and the binocular visual unit has a 30° tilt that is convenient for long-term use. The eyepieces are wide-field and provide a magnification of 10x, the revolving device accommodates four lenses - achromatic lenses with magnifications of 4x, 10x, 40x and 100x are already installed in it. The 100x objective can be used for oil immersion. Please note that the 40x and 100x lenses have special spring frames that protect the front lens from accidental damage. Samples for research are placed under the lens using a drug driver. The sharpness of the optics is adjusted using the coarse and fine focusing knobs. The lighting system is located under the object stage and has brightness adjustment. The backlight is an LED with a collector, and the Abbe condenser is equipped with an iris diaphragm and filter holder. It is convenient that the microscope can be powered by rechargeable batteries, and not just from the mains. Charger and batteries are included.
