Porcelain Crucibles CHF-10-20 10ml with Lid by GSC International

Description

Product Overview

The CHF-10-20 porcelain crucible from GSC International is engineered for demanding laboratory environments where precision, durability, and thermal performance are paramount. Each crucible holds a precise 10 ml volume, offering a compact yet robust solution for a wide range of analytical and preparative tasks. Constructed from high‑quality white porcelain, the crucible exhibits a uniform, dense structure that minimizes permeability and maximizes mechanical strength, ensuring consistent performance even under repeated heating cycles.

Accompanied by a snug-fitting lid, the set provides an enclosed environment that helps maintain sample integrity, reduces contamination risk, and improves safety during high‑temperature operations. The glazed variant of the crucible can withstand temperatures up to 1050 °C, while the unglazed version extends that limit to 1350 °C, giving users flexibility to select the appropriate model based on their specific thermal requirements.

Usage

These crucibles are ideally suited for a variety of laboratory applications, including but not limited to small‑scale synthesis, analytical digestion, sample preparation for spectroscopy, and thermal analysis. Researchers in chemistry, materials science, and environmental testing frequently rely on the consistent volume and thermal stability of porcelain crucibles to achieve reproducible results.

In educational settings, the CHF-10-20 crucible serves as a reliable teaching tool for demonstrating fundamental concepts such as heat transfer, phase changes, and reaction kinetics. Its high‑form design facilitates easy handling and placement on standard laboratory hot plates, furnaces, and muffle ovens, while the lid helps retain volatile compounds and protect users from splatter.

FAQ

Can the crucible be used in a standard laboratory furnace?

Yes, the CHF-10-20 porcelain crucible is designed for use in conventional laboratory furnaces, muffle ovens, and hot plates. The glazed version is safe up to 1050 °C, while the unglazed version can handle temperatures as high as 1350 °C, making it suitable for most high‑temperature applications.

Is the lid compatible with both glazed and unglazed crucibles?

The lid is engineered to fit securely on both glazed and unglazed crucibles, providing a tight seal that helps retain volatile substances and protect the user from splatter. It is made from the same high‑quality porcelain material to ensure uniform thermal expansion.

How should I clean the crucible after use?

For routine cleaning, rinse the crucible with warm water and a mild detergent, then allow it to air‑dry. For more stubborn residues, a gentle soak in a dilute acid solution (e.g., 5 % nitric acid) followed by thorough rinsing is recommended. Avoid abrasive scrubbers that could damage the glazed surface.

What is the difference between glazed and unglazed versions?

The glazed version features a smooth, glass‑like coating that enhances chemical resistance and allows operation up to 1050 °C. The unglazed version lacks this coating, offering a higher temperature tolerance of up to 1350 °C but with a slightly more porous surface, which may be preferable for certain high‑temperature processes.
