The Levenhuk 400T is a classic trinocular microscope with a binocular visual part and a vertical tube for installing a digital camera in it. This microscope is an excellent choice for a laboratory. It will help a medical worker, microbiologist, biochemist, or any other specialist who studies biological samples. The microscope uses the achromatic optics and comes with an LED light. A bright field method and oil immersion can be used for research.

A microscope head is rotatable, which is practical for group work. A visual part is inclined at 30°: that makes lengthy work with a microscope more comfortable. The 10x eyepieces provide a wide field of view, while achromatic optics deliver details of small structures clearly and sharply. The objectives with 4x, 10x, 40x, and 100x magnification are installed in a revolving nosepiece. Overall microscope magnification varies from 40x to 1000x. Please note that this microscope allows for applying oil immersion research method using a 100x objective. What is more, 40x and 100x objectives feature protective spring-loaded frames.

The stage is equipped with a mechanical scale. Next to the stage, there are fine and coarse focusing knobs. Right underneath, there is a bright field Abbe condenser with an iris diaphragm and a filter holder. The lighting system consisting of an LED light and collector is located even lower. The lighting features brightness adjustment and is powered by batteries or an AC power supply. The microscope body is made of metal.
