Microscope Slide EISCO BS18003 Transparent Glass Single Slide Letter e

Description

Product Overview

The EISCO BS18003 microscope slide is engineered for educational environments where clarity and durability are essential. Crafted from high‑quality transparent glass, the slide offers a pristine viewing surface that resists scratches and chemical damage, ensuring consistent optical performance over repeated use. Its dimensions of 75 mm by 25 mm (approximately 1 × 3 × 0.1 inches) match standard microscope stage requirements, allowing seamless integration with most classroom and laboratory microscopes.

Each slide features a single, pre‑printed capital letter “e” rendered with a permanent, non‑reactive ink that does not interfere with light transmission. This simple yet effective visual marker serves as a reference point for teaching fundamental concepts such as image inversion, magnification, and focal plane adjustment. The slide is lightweight at just 1.6 ounces, making it easy to handle while still providing the robustness needed for frequent student use.

Packaging includes a sturdy cardboard case that protects the glass from impact and dust during storage and transport. The case is designed for quick access, allowing educators to retrieve slides efficiently during lesson plans. The model number BS18003 and the brand name EISCO are clearly marked on the packaging, facilitating inventory management for schools and laboratories that maintain multiple slide types.

Usage

In a typical classroom setting, the EISCO slide is introduced during the first microscopy unit to illustrate how a specimen appears under low and high magnification. Instructors can place the slide on the microscope stage, focus on the printed “e,” and demonstrate how the image flips horizontally and vertically as the objective lens changes. This hands‑on activity reinforces theoretical lessons about light paths and image formation, making abstract concepts tangible for students.

The slide also proves valuable in more advanced labs where students practice slide preparation techniques. Because the glass surface is clean and flat, learners can experiment with adding temporary coverslips or mounting media without risking contamination of a delicate specimen. The slide’s durability ensures that even after multiple handling cycles, the printed letter remains legible, providing a reliable reference point throughout the semester.

FAQ

What is the best magnification to view the printed letter on the slide?

For clear observation of the printed “e,” start with a low‑power objective (4× or 10×) to locate the letter, then switch to a higher‑power objective (40× or 100×) to examine the details of the ink and the glass surface. This step‑by‑step approach helps students understand how magnification changes the apparent size of the image.

Can the slide be used with oil immersion lenses?

Yes, the slide can be examined with oil immersion lenses, but because the printed letter is on the surface, there is no need to add immersion oil. If a student wishes to practice oil immersion techniques, they can place a small drop of oil on a separate blank area of the slide without affecting the printed marker.

Is the slide compatible with digital microscopes?

Absolutely. The transparent glass and clear printing make the slide ideal for capture with digital microscopes or smartphone adapters. The high‑contrast letter “e” provides an excellent test pattern for calibrating camera focus and exposure settings.

How should the slide be cleaned after use?

After each class, gently wipe the slide with a lint‑free cloth dampened with distilled water. Avoid abrasive cleaners or solvents, as they can damage the glass surface or alter the printed ink. Store the slide back in its protective case to keep it free from dust and scratches.

What educational standards does this slide support?

The slide aligns with common science curriculum standards that cover optics, microscopy, and scientific observation. It serves as a practical tool for meeting objectives related to understanding light behavior, image formation, and proper laboratory techniques.
