Alumina Crucible 5ml High Form 99.3% White Pack of 10 Lab4us

Description

Product Overview

The Lab4us Alumina Crucible is engineered for precision scientific work, offering a compact 5ml volume that fits comfortably into standard laboratory setups. Constructed from 99.3% pure alumina (Al2O3), the crucible delivers outstanding resistance to thermal shock and chemical corrosion, making it a dependable choice for demanding high‑temperature applications.

Its high‑form geometry provides a deep, stable chamber that minimizes spillage while allowing easy access for sample loading and retrieval. The white ceramic finish not only signals purity but also aids in visual inspection of contents during heating cycles. With a maximum working temperature of 1750°C, this crucible can accommodate a wide range of processes, from metal alloy melting to ceramic sintering and advanced material synthesis.

Each crucible undergoes rigorous quality control to ensure uniform wall thickness and dimensional accuracy, guaranteeing consistent performance batch after batch. The product is supplied in a convenient pack of ten, reducing the need for frequent reordering and providing cost‑effective inventory for busy research environments.

Designed with the modern laboratory in mind, the crucible’s dimensions (approximately 4 × 4 × 3 inches) allow it to fit into most furnace racks, crucible holders, and heating blocks without modification. The lightweight 8‑ounce package makes handling straightforward while still offering the durability required for repeated high‑temperature cycles.

Lab4us, the manufacturer, has a reputation for delivering reliable labware that meets stringent industry standards. This crucible reflects that commitment, offering a blend of material excellence, functional design, and user‑friendly packaging that supports both routine experiments and cutting‑edge research.

Usage

Ideal for academic laboratories, industrial research facilities, and educational institutions, the Alumina Crucible excels in environments where precise temperature control and material purity are critical. Researchers can employ it for melting small metal samples, conducting high‑temperature oxidation studies, or synthesizing advanced ceramic composites.

Because of its high thermal stability, the crucible is also suitable for use in vacuum furnaces, inert atmosphere glove boxes, and rapid‑thermal‑processing equipment. Its chemical inertness ensures that it will not react with most metals, oxides, or non‑metallic compounds, preserving sample integrity throughout the experiment.

When handling the crucible, users should employ standard laboratory safety protocols, including the use of heat‑resistant gloves and tongs. The deep design reduces the risk of spillage, but careful loading and unloading are recommended to maintain a clean work environment and protect furnace interiors.

For educational demonstrations, the clear white body allows students to observe phase changes and material behavior in real time, enhancing learning outcomes in materials science and engineering courses.

FAQ

What is the maximum temperature this crucible can withstand?

The crucible is rated for continuous operation up to 1750°C, making it suitable for most high‑temperature laboratory applications.

Can the crucible be used in a vacuum furnace?

Yes, the alumina material is chemically inert and can safely be used in vacuum or inert‑gas environments without reacting with the sample.

How should I clean the crucible after use?

Allow the crucible to cool completely, then gently brush away residues with a soft, non‑metallic brush. For stubborn deposits, a mild alkaline solution can be used, followed by thorough rinsing with deionized water.

Is the pack of ten crucibles suitable for bulk purchasing?

Absolutely. The ten‑piece pack is designed for laboratories that require multiple crucibles for repeated experiments, offering a convenient and economical solution.

What safety precautions are recommended when handling the crucible?

Always use heat‑resistant gloves and appropriate tongs when loading or unloading the crucible from a furnace. Ensure the furnace is properly calibrated and follow standard laboratory safety protocols.
