Key Applications & Uses

• Advanced classroom and laboratory observation of bacterial smears, stained microorganisms, plant/animal cells, protozoa, algae, histological sections, and high-resolution cellular structures in high school and introductory university biology/microbiology programs.
• Hands-on student experiments involving slide preparation, Gram staining, wet mounts, oil immersion technique, and detailed examination at 1000x–1250x for cellular organelles, bacterial morphology, and tissue details.
• Educational demonstrations in science clubs, homeschooling advanced curricula, university foundation labs, and outreach programs teaching cytology, bacteriology, botany, zoology, and microscopy techniques requiring high magnification and contrast control.
• Introduction to professional-grade features (oil immersion, Abbe condenser with iris, vernier stage) in educational settings without electricity dependency, suitable for remote schools, field demonstrations, or sustainable teaching environments.
• Entry-level training in junior research labs to master mechanical stage operation, condenser adjustment, oil immersion microscopy, fine focusing, and high-resolution specimen analysis before transitioning to powered or research-grade microscopes.

Frequently Asked Questions (FAQs)

Q: What is the maximum magnification of the GHEXA-11.1508-04? A: With the 12.5x eyepiece and 100x oil immersion objective, the microscope achieves 1250x magnification—ideal for high-resolution observation of bacteria, cellular organelles, and fine structures in educational settings.

Q: How do I properly use the 100x oil immersion objective? A: Apply a small drop of immersion oil between the slide and the 100x objective, carefully lower the objective until it contacts the oil, then use fine focus only. Open the iris diaphragm fully and center the condenser for maximum resolution.

Q: What advantages does the vernier scale stage provide? A: The coaxial vernier mechanical stage allows precise, smooth X-Y movement with measurable increments—essential for locating specific areas on slides, systematic scanning, and teaching accurate specimen navigation techniques.

Q: How do I optimize illumination with the mirror? A: Use the concave side to concentrate light from a window or desk lamp for brighter, focused illumination at higher magnifications; use the plane side for even lighting. Adjust mirror angle and position near a strong light source.

Q: Is the condenser height-adjustable? A: Yes—the N.A. 1.25 Abbe condenser is height-adjustable and features an iris diaphragm, allowing students to optimize light intensity, contrast, and resolution for each objective.

Q: What is the shipping configuration? A: 4 complete microscopes are securely packed per master carton (53 × 43 × 39 cm, 15 kg gross / 14 kg net), ensuring safe delivery to schools, educational suppliers, or institutions. Contact G-Hexa for bulk pricing or custom orders.
