Dampness and Volatility Handling

The crucible shows strong resistance to unpredictable substances and dampness . It does not take in water from the air, which aids keep consistent weight throughout accurate gravimetric evaluation. Its thick structure avoids gas or vapor penetration throughout heating cycles.

Physical Features

– Thickness: ≥ 3.6 g/cm FOUR.
– Hardness: Mohs 9 (really hard and scratch-resistant).
– Thermal development coefficient: Low, making sure good thermal shock resistance.
– Color: White or off-white, showing high purity.

Common Research Laboratory Uses

This crucible is extensively used in analytical chemistry, products testing, and quality control laboratories. Common applications consist of ashing organic samples , melting glass or changes, and holding responsive products at heats. It works well in muffle heaters, tube heaters, and other high-heat environments.

Care and Handling

Constantly warmth and cool the crucible slowly to prevent thermal shock. Use clean tongs to manage it when hot. Do exempt it to abrupt influences or mechanical stress, as alumina is tough however breakable.

Applications of Cylindrical Diamond Crucible– 99% Pure Alumina Laboratory Crucible

High-Temperature Security for Requiring Tasks

This cylindrical corundum crucible is made from 99% pure alumina (porcelain-grade). It manages severe heat without damaging down. The product remains steady even above 1600 ° C. That makes it perfect for tasks where various other containers would certainly fall short.

Perfect for ash web content screening. Labs utilize it to burn natural samples entirely. The crucible holds up during long term heating in muffle heaters. No splits. No contamination. Outcomes remain precise.

Resists Moisture and Volatile Chemicals

The thick alumina structure blocks dampness absorption. This matters when you work with hygroscopic materials or require completely dry conditions. The crucible likewise stands up to strike from many volatile materials released throughout heating. Acids, alkalis, and reactive gases won’t deteriorate its surface area quickly.

Great for fusion and melting. Technicians melt glass, steels, or salts inside it. The smooth interior avoids sample sticking. Cleaning ends up being straightforward. Reuse is safe and dependable.

Developed for Precision Laboratory Job

Its round shape gives consistent wall density. Heat spreads equally. Thermal shock resistance is strong– so abrupt temperature modifications create no damage. The flat base sits constant on warmers or in heating system chambers.

Used across several fields. Chemistry labs, products study, ecological testing, and quality assurance all depend upon this crucible. It supports XRF example prep, loss-on-ignition tests, and high-purity synthesis.

Every batch satisfies stringent pureness requirements. Trace pollutants are kept very reduced. That guarantees your experiments stay devoid of unwanted interference. Whether you’re examining soil, concrete, or drugs, this crucible supplies regular efficiency under pressure.

5 FAQs of Cylindrical Corundum Crucible 99 Porcelain Alumina Laboratory Crucible Resistant to High Temperature Volatile Moisture Ash

Frequently Asked Questions

What is a cylindrical corundum crucible made of?

This crucible is made from 99% pure alumina (aluminum oxide). It is also called high-purity porcelain or corundum. The material gives it strong resistance to heat and chemical reactions.

Why choose a 99% alumina crucible for lab work?

Because it can handle very high temperatures—up to 1700°C (3092°F)—without melting or deforming. It also resists attack from most acids, bases, and molten metals. This makes it ideal for ash testing, sample fusion, and other high-heat lab procedures.

Can this crucible hold volatile or moist samples?

Yes. The dense structure of 99% alumina prevents moisture or vapors from seeping through. It stays stable even when heating wet or volatile substances. Just make sure to heat slowly at first to avoid sudden steam pressure.

How do I clean and reuse the crucible?

Let it cool fully after use. Then wash it with distilled water and a soft brush. For stubborn residues, soak it in dilute acid (like nitric or hydrochloric acid) for a short time. Rinse well and dry before the next use. Avoid sudden temperature changes to prevent cracking.

Is this crucible safe for repeated high-temperature use?

Yes. Its high purity and dense microstructure give it excellent thermal shock resistance. It can be heated and cooled many times without breaking—just follow proper heating and cooling rates. Always place it on a heat-resistant surface and never drop it when hot.
