Cell Lab Alumina Vacuum Milling Jar

Cell Lab Alumina Vacuum Milling Jar [50ml–1000ml | Al₂O₃ Grinding Jar with Stainless Steel Vacuum Sleeve]

High-purity alumina vacuum grinding jars designed for planetary ball milling under vacuum or inert gas environments.

General Description

The Cell Lab Alumina Vacuum Milling Jar Series is engineered for high-purity grinding and milling applications where oxidation, contamination and airborne exposure must be minimised during processing.

Manufactured from high-purity aluminium oxide ceramic (Al₂O₃) and protected by a durable 304 stainless steel vacuum jacket, these vacuum milling jars provide excellent wear resistance, thermal stability and sealing performance for sensitive laboratory milling applications.

These jars are specifically designed for vacuum milling or inert gas grinding environments, making them ideal for oxygen-sensitive materials, ceramic powders, battery materials, minerals and advanced functional materials.

Each vacuum jar assembly includes the grinding jar, vacuum lid, silicone sealing gasket and stainless steel vacuum sleeve. Multiple capacities from 50ml to 1000ml are available to support laboratory-scale R&D and pilot-scale material preparation.

Key Features

• Vacuum and inert gas milling capability — Prevents oxidation and airborne contamination during grinding and mixing processes.

• High-purity alumina ceramic construction — Provides excellent hardness, wear resistance and low contamination performance.

• Durable stainless steel vacuum sleeve — SUS304 stainless steel outer jacket improves vacuum sealing strength and mechanical durability.

• Excellent thermal and chemical stability — Suitable for abrasive, fibrous and chemically sensitive samples.

• Wide capacity range from 50ml to 1000ml — Supports laboratory research, ceramic processing and powder material development.

FAQ

Q1: Why use an alumina vacuum milling jar?

Alumina vacuum jars reduce oxidation and contamination during grinding while offering excellent wear resistance and chemical stability.

Q2: What grinding media should be used with these jars?

Alumina grinding balls are recommended to maintain low contamination and maximise durability.

Q3: Can these jars operate under inert gas environments?

Yes. These jars are designed for both vacuum and inert gas milling applications.

Q4: What is the recommended filling capacity?

The total material and grinding media load should not exceed two-thirds of the jar volume.

Q5: Are these suitable for ceramic and battery material research?

Yes. These jars are widely used for ceramic powders, cathode materials, anode materials and advanced functional materials.
