Key Applications & Uses

• Advanced classroom observation of prepared slides, bacterial smears, plant/animal cells, protozoa, algae, histological sections, and stained microorganisms in high school and introductory university biology/microbiology programs.
• Hands-on student experiments involving slide preparation, Gram staining, simple wet mounts, and high-resolution viewing (especially at 1000x with oil immersion) of cellular and microbial structures.
• Educational demonstrations in science clubs, homeschooling advanced curricula, university foundation labs, and outreach programs teaching cytology, bacteriology, botany, zoology, and basic microscopy techniques.
• Introduction to oil immersion microscopy for detailed cellular and subcellular observation using natural or directed light—no electricity required, making it suitable for remote or power-limited educational environments.
• Entry-level training in junior research labs and educational institutions to master compound microscope operation, vernier stage positioning, condenser adjustment, fine focusing, and oil immersion before progressing to powered or research-grade instruments.

Frequently Asked Questions (FAQs)

Q: What is the maximum magnification of the GHEXA-11.1508-03? A: With the 10x eyepiece and 100x oil immersion objective, the microscope achieves 1000x magnification—suitable for detailed observation of bacteria, cellular organelles, and fine structures in educational settings.

Q: How do I use the 100x oil immersion objective? A: Place a drop of immersion oil between the 100x objective and the slide, carefully lower the objective until it contacts the oil, then use fine focus only. The N.A. 1.25 condenser and iris diaphragm must be fully open and centered for best resolution.

Q: How does the vernier scale stage help students? A: The coaxial vernier stage allows precise, smooth movement of the slide in X and Y directions with measurable increments—ideal for locating specific areas, counting cells, or teaching systematic scanning techniques.

Q: Can this microscope be used without electricity? A: Yes—it relies entirely on the plan-concave mirror for illumination. Use ambient room light, a window, or an external desk lamp directed into the mirror for optimal brightness.

Q: Is the condenser adjustable for different objectives? A: Yes—the N.A. 1.25 Abbe condenser with iris diaphragm is height-adjustable and iris-controllable, allowing students to optimize light and contrast for low- to high-power objectives.

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.
