Microscope Dromader ZD-4135 — magnification 100x, 200x, 450x

Dromader ZD-4135 is a compact compound microscope offering three selectable magnification levels: 100x, 200x and 450x. Designed for basic biological observation, educational demonstrations and hobbyist use, this model allows users to view prepared slides and small specimens with clear, stepped optical enlargement. The instrument combines a straightforward mechanical design with optical settings that support classroom activities, home study and introductory laboratory tasks.

Advantages

The microscope delivers three fixed magnification options that are easy to switch between, enabling progressive examination from low to high detail. Its construction focuses on user-friendly operation, straightforward focusing and stable specimen viewing suitable for learners and hobbyists. The optical arrangement provides sufficient detail for identifying common cellular structures, small organisms and fine surface textures when using properly prepared slides.

Suitable for

• School and classroom biology demonstrations
• Student laboratory practice and coursework
• Hobbyist specimen observation (plant tissue, insects, small mineral samples)
• Introductory microbiology and basic slide examination

Key specifications

• Optical magnifications: 100×, 200×, 450×
• Type: compound microscope for transmitted-light observation
• Intended use: prepared slides and small opaque or translucent specimens
• Focus control: coarse and fine focusing mechanism (manual)
• Illumination: built-in transmitted light source for slide observation
• Stage: mechanical or plain stage suitable for standard slides
• Application areas: education, hobby, introductory laboratory work

How to use

Place a prepared slide on the stage and secure it with the stage clips or mechanical stage. Start with the lowest magnification (100×) to locate the area of interest and use coarse focus to bring the specimen into view, then refine with fine focus. Switch to higher magnification (200× or 450×) as needed to examine finer details, making small focus adjustments each time. Adjust the illumination intensity to improve contrast and clarity for translucent samples. When finished, lower the stage, remove the slide, turn off the light source and cover the microscope if storage is required.

Usage recommendations

For reliable results, use properly prepared and clean slides, avoid excessive light intensity that may wash out details, and always handle optical components by their edges. Regularly clean lenses with appropriate lens tissue and store the instrument in a dry, dust-free place to maintain optical performance.
