Chemglass CG-1906-22 Borosilicate Disc 6″ Diameter 1/4″ Height

Description

Product Overview

The Chemglass CG-1906-22 is a precision‑engineered borosilicate glass disc designed specifically for thin layer chromatography (TLC) applications. Measuring 6 inches in diameter and a quarter‑inch in height, this plate provides a generous surface area for sample application while maintaining a thin profile that promotes rapid solvent migration and clear separation of analytes. Constructed from high‑quality Pyrex or Duran borosilicate glass, the disc offers superior chemical resistance, thermal stability, and optical clarity, ensuring that even the most demanding solvents and reagents do not compromise the integrity of the plate. The smooth, uniform surface minimizes sample tailing and promotes reproducible spot morphology, which is essential for quantitative analysis. With a package dimension of 8.3 × 6.5 × 6.5 inches and a lightweight design of just one pound, the disc is easy to store, transport, and integrate into existing laboratory workflows. Its compatibility with standard TLC chambers and development solvents makes it a versatile choice for both routine analytical procedures and advanced research projects.

Usage

This borosilicate disc is suited for a wide range of laboratory environments, from academic research labs to industrial quality‑control facilities. It excels in applications that require high‑resolution separation of organic compounds, pharmaceuticals, natural products, and polymers. The disc can be used with conventional TLC plates, allowing analysts to apply samples using capillary tubes, micropipettes, or automated spotters. Its robust glass composition tolerates a variety of solvents, including polar protic solvents like methanol and ethanol, as well as non‑polar solvents such as hexane and chloroform, without etching or degradation. The disc’s flat geometry facilitates even solvent front movement, reducing edge effects and ensuring consistent Rf values across the entire surface. Users can employ the disc in both horizontal and vertical development chambers, and it is compatible with visualization techniques such as UV illumination, iodine staining, and chemical derivatization. The product’s durability also makes it ideal for repeated use after proper cleaning, extending its service life and providing cost‑effective performance for high‑throughput screening.

FAQ

Can this disc be reused after cleaning?

Yes, the borosilicate glass can be gently cleaned with appropriate solvents and a soft brush. After thorough drying, the disc retains its optical clarity and chemical resistance for repeated TLC runs.

Is the disc compatible with automated spotting equipment?

Absolutely. The flat, uniform surface is designed to work with most automated spotters, allowing precise volume control and high‑throughput sample application.

What solvents are safe to use with this glass disc?

The disc tolerates a broad range of solvents, including polar protic solvents (methanol, ethanol), polar aprotic solvents (acetone, acetonitrile), and non‑polar solvents (hexane, chloroform). Avoid highly corrosive acids or bases that exceed the glass’s chemical resistance limits.

How does the disc compare to traditional silica‑gel TLC plates?

While silica‑gel plates provide a stationary phase, the Chemglass disc offers a chemically inert, optically clear substrate that can be coated with custom stationary phases or used as a support for pre‑coated plates. Its glass base eliminates background interference and provides superior thermal stability.

What is the recommended storage condition for the disc?

Store the disc in a clean, dry environment away from direct sunlight and extreme temperature fluctuations. Keeping it in a sealed container helps prevent dust accumulation and maintains surface integrity.
