BQLZR Alumina Ceramic Crucible Holder 3.15×1.57×0.71″ 50ml Pack of 3

Description

Product Overview

The BQLZR Alumina Ceramic Crucible Holder is engineered for demanding laboratory environments where temperature stability and material integrity are paramount. Each holder is crafted from high‑purity alumina ceramic, a material renowned for its ability to endure temperatures up to 1700 °C without deformation or chemical interaction. The rectangular design measures 3.15×1.57×0.71 in (80×40×18 mm) and provides a 50 ml capacity, allowing users to melt approximately 400 g of copper or similar metals in a single batch. The pack includes three identical crucibles, each weighing just 8.3 oz, making them easy to handle while still offering robust durability. Packaged in a compact box (9.05×5.51×1.37 in), the set is ready for immediate deployment in any lab setting, from academic research to industrial prototyping.

Usage

These crucibles excel in a variety of high‑temperature applications. Whether you are performing metal casting, alloy synthesis, or thermal analysis, the alumina construction ensures minimal contamination and consistent heat distribution. To use, simply place the desired material into the crucible, position it within a furnace or kiln, and heat gradually to the target temperature. Because alumina exhibits low thermal expansion, it reduces the risk of cracking during rapid temperature changes, though it is still recommended to follow a controlled heating and cooling schedule to maximize lifespan. The holders are compatible with standard laboratory equipment, including crucible tongs, furnace racks, and ceramic trays, making integration seamless. Their resistance to corrosive gases and molten metals further expands their suitability for advanced research in metallurgy, materials science, and chemical engineering.

FAQ

Can these crucibles be used for non‑metallic materials?

Yes, the alumina ceramic is chemically inert and can safely hold glass, ceramics, and certain polymers during high‑temperature treatments, provided the material does not exceed the crucible’s temperature rating.

What is the recommended heating rate to avoid cracking?

It is advisable to increase temperature gradually, typically no more than 10 °C per minute, and allow a controlled cooldown period of at least 30 minutes to minimize thermal stress.

Are the crucibles compatible with standard laboratory tongs?

Absolutely. The dimensions and weight of each crucible are designed to work with common crucible tongs and handling tools used in most laboratory environments.

How do I clean the crucibles after use?

After cooling, remove residual material with a soft brush and, if necessary, a mild alkaline solution. Rinse thoroughly with deionized water and dry before the next use to preserve the alumina surface.

What warranty does BQLZR provide?

BQLZR offers a one‑year limited warranty covering manufacturing defects. Contact customer service with the purchase details for a replacement or repair if any issues arise within the warranty period.
