Clear Glass Rectangular Block 115x65x20mm United Scientific Supplies

Description

Product Overview

The United Scientific Supplies RCB115-G is a precision‑engineered clear glass rectangular block designed for scientific and educational use. Measuring 115 mm in length, 65 mm in width, and 20 mm in thickness, the block provides a substantial surface area for light transmission experiments while remaining compact enough for standard laboratory benches. Its polished glass surface delivers high optical clarity, minimizing distortion and allowing accurate observation of refraction, reflection, and dispersion phenomena.

Manufactured from high‑grade soda‑lime glass, the block undergoes a rigorous polishing process that removes surface imperfections and ensures a uniform index of refraction across the entire piece. The material is chemically stable, resistant to thermal shock, and maintains its clarity even after repeated cleaning with standard laboratory solvents. This durability makes the block suitable for long‑term use in both classroom settings and research laboratories.

Each block is inspected for dimensional accuracy and visual defects before packaging. The tolerances are kept within ±0.2 mm for length and width, and ±0.1 mm for thickness, guaranteeing that experimental setups requiring precise geometry can rely on consistent results. The block’s rectangular shape also facilitates easy mounting on optical rails, holders, and custom rigs, providing flexibility for a wide range of experimental configurations.

Beyond its optical performance, the RCB115-G offers safety features such as rounded edges and a smooth surface that reduce the risk of cuts or breakage during handling. The block complies with relevant safety standards for laboratory glassware, ensuring that it can be used confidently in environments where student safety is a priority.

Overall, the United Scientific Supplies RCB115-G combines superior material quality, precise dimensions, and user‑friendly design to serve as a reliable component for any experiment involving light manipulation, optical measurement, or visual demonstration.

Usage

This glass block is ideally suited for a variety of educational and research applications. In physics classrooms, it can be used to demonstrate Snell’s law, total internal reflection, and prism dispersion by placing the block in a laser beam path. Its clear, flat faces allow students to observe the bending of light with minimal visual artifacts, reinforcing theoretical concepts with hands‑on experience.

In chemistry labs, the block can serve as a stable platform for spectroscopic cuvettes or as a transparent barrier in diffusion experiments. Its chemical resistance ensures that exposure to common reagents does not degrade the glass, preserving optical performance over time. Researchers conducting optical fiber alignment or waveguide testing also find the block valuable for its predictable refractive index and flat surfaces.

For hobbyists and makers, the RCB115-G provides a versatile component for DIY optics projects, such as building simple microscopes, periscopes, or light‑guiding devices. Its manageable size makes it easy to incorporate into home‑based setups, and the polished finish reduces stray reflections that could interfere with experimental observations.

When used in professional settings, the block can be integrated into calibrated optical benches, serving as a reference element for precision measurements. Its dimensional stability under temperature variations ensures that data collected in controlled environments remains accurate, supporting high‑quality research outcomes.

Regardless of the specific application, the block’s ease of cleaning—simply rinse with distilled water and mild detergent—keeps it ready for repeated use without compromising clarity. Users are encouraged to handle the block by its edges and store it in a protective case when not in use to maintain its pristine condition.

FAQ

What is the refractive index of the glass block?

The block is made from standard soda‑lime glass, which typically has a refractive index of approximately 1.52 at visible wavelengths. This value is suitable for most educational and basic research applications involving light refraction.

Can the block be used with laser beams?

Yes, the block’s polished surfaces are designed to handle low‑power laser beams commonly used in classroom demonstrations. For higher‑power lasers, appropriate safety precautions and beam attenuation should be employed.

Is the block compatible with standard optical holders?

The rectangular dimensions and flat faces allow the block to fit securely into most standard optical breadboards, clamps, and custom holders designed for 100 mm‑scale components.

How should I clean the glass block after use?

Rinse the block with distilled water to remove residues, then gently wipe with a lint‑free cloth. If needed, use a mild laboratory detergent, avoiding abrasive cleaners that could scratch the surface.

What warranty does United Scientific Supplies offer?

We provide a one‑year limited warranty covering manufacturing defects. If the block arrives damaged or develops a defect under normal use, contact our support team for a replacement or refund.
