performance binocular biological microscope designed for students, laboratory work, and biological experiments. Combines durable metal construction with fully coated optics and features typically found on higherend instruments. Key benefits Clear, reliable imaging: achromatic objectives at 4x, 10x, 40x, and 100x deliver sharp, colorcorrected views for a wide range of specimens. Comfortable viewing: binocular head reduces eye fatigue during extended use and supports collaborative observation. Robust and precise: aluminum alloy body and metal components provide longterm stability and alignment for consistent results. Versatile illumination and contrast control: 50 mm concave plan reflector and basic condenser concentrate light for improved contrast; builtin iris diaphragm and filter allow precise control of illumination. Ready for classroom or lab: simple flat stage with clip and compact footprint makes setup and sample handling straightforward. Features and specifications Indicator head: binocular. Objectives (achromatic): 4x, 10x, 40x, 100x. Eyepieces: Huygens style available in 10x and 16x. Stage: flat stage with clip; stage size 120 x 120 mm. Optical and mechanical ranges: setting range 50; good adjustment range 1.8 2.2 mm. Illumination: concave plan reflector, 50 mm. Construction: fully coated glass optics; aluminum alloy body; metal caps and fittings. Microscope Dia Class: thickness 1 1.2 mm; size 25.4 x 76.2 mm. Accessories: 24 x 24 mm thick glass slides, thickness 0.13 0.17 mm, 100 pieces per box. Practical use scenarios Classroom teaching: Durable construction and binocular viewing make this microscope suitable for student labs, demonstrations, and routine classroom microscopy exercises. Research and lab experiments: Achromatic objectives up to 100x oil immersion allow detailed observation of cells, tissues, and prepared slides for basic research tasks and lab protocols. Prepared slide work and sample processing: Flat stage with clip and consistent illumination control simplify the preparation and inspection of multiple slides in training or diagnostic workflows. What makes it stand out Professional optical set: achromatic objective series plus Huygens eyepieces deliver full range magnification and reliable image quality. Practical design for frequent use: metal housing, coated optics, and a simple stage reduce maintenance and support steady performance in educational and laboratory environments. Complete slide supply option: compatible slides available in 24 x 24 mm format, thickness 0.13 0.17 mm, packed 100 per box for routine sample work. This microscope provides a balanced combination of optical performance, mechanical reliability, and userfriendly controls suitable for students, labs, and general biological microscopy applications.
