Key Applications & Uses

• Advanced classroom and laboratory observation of bacterial smears, stained microorganisms, plant/animal cells, protozoa, algae, histological sections, and fine cellular/subcellular 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 high-magnification (1000x–1500x) examination of bacterial morphology, cellular organelles, and tissue details.
• Educational demonstrations in science clubs, homeschooling advanced curricula, university foundation labs, and outreach programs teaching cytology, bacteriology, botany, zoology, and professional microscopy techniques requiring high resolution and contrast control.
• Introduction to oil immersion and Abbe condenser usage in educational settings without electricity dependency, ideal 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 moving to powered or research-grade instruments.

Frequently Asked Questions (FAQs)

Q: What is the maximum magnification of the GHEXA-11.1508-05? A: With the 15x eyepiece and 100x oil immersion objective, the microscope achieves 1500x magnification—ideal for high-resolution observation of bacteria, cellular organelles, and fine structures in educational settings.

Q: How do I correctly use the 100x oil immersion objective? A: Place a 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. Set the iris diaphragm fully open and center the condenser for maximum resolution.

Q: Why is the vernier scale stage important for students? A: The coaxial vernier mechanical stage allows precise, measurable X-Y movement—crucial for locating specific slide areas, systematic scanning, counting cells, or teaching professional specimen navigation techniques.

Q: How do I get the best illumination from 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 adjustable for different objectives? 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 and magnification.

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.
