Technical Parameters

Product Description:

The KS-GPM-8 is a precision-engineered agate grinding mill designed to meet the demanding needs of modern laboratories in materials science, chemistry, electronics, and environmental research. With a compact form factor and advanced automation features, this mill is ideal for researchers seeking high-efficiency, low-contamination grinding in controlled environments.

The heart of the KS-GPM-8 lies in its robust construction and the use of natural agate as the grinding material. Agate is widely appreciated in scientific applications for its high hardness, excellent chemical resistance, and non-metallic properties, making it the ideal medium for processing sensitive samples such as semiconductors, minerals, biological tissues, rare-earth materials, or high-purity powders. Unlike metal or ceramic grinding vessels, agate minimizes sample contamination and preserves the original chemical composition of specimens.

This model is specifically designed for precision grinding tasks where consistency, repeatability, and purity are critical. It employs an automatic rotating mechanism that enables both the mortar and pestle to work together harmoniously to achieve fine and uniform particle sizes. The pressure applied during grinding is carefully regulated using an internal spring system, which reduces operator intervention and increases reproducibility across multiple runs.

KS-GPM-8 features a compact vertical design that conserves bench space while maintaining excellent operational stability. Its modern appearance is complemented by intuitive operation, suitable for both experienced researchers and laboratory technicians. The machine operates with very low vibration and noise, which enhances user comfort and allows integration into cleanrooms or gloveboxes. In fact, the grinder’s enclosure-friendly dimensions and modular structure enable it to be placed inside a glove box via an airlock, making it suitable for working with air-sensitive or hazardous materials under inert gas environments.

One of the key advantages of the KS-GPM-8 is its user-centric design. Every aspect—from the grinding bowl’s geometry to the spatula included for improved mixing—has been optimized for laboratory efficiency. The agate bowl and pestle are easy to disassemble and clean, reducing downtime between sample runs and preventing cross-contamination. The supplied spatula is designed to evenly distribute materials during grinding, ensuring a more uniform mixture and preventing sample build-up along the bowl walls.

This grinder supports dual-speed adjustment for the mortar and pestle, providing flexible control over the grinding action. The pestle rotation can be finely tuned to suit different materials and sample types, whether delicate or hard. This flexibility makes the KS-GPM-8 well-suited for both soft organic samples and brittle crystalline solids, accommodating a wide range of research and development workflows.

In addition to its performance and design advantages, the KS-GPM-8 is backed by a reliable support program, including a two-year limited warranty and lifetime technical assistance. This ensures that users not only receive a reliable piece of laboratory equipment but also ongoing support throughout the instrument’s service life.

Safety is another priority in the KS-GPM-8. The enclosed grinding chamber prevents material spillage and reduces exposure to fine particulates, which is particularly important when working with toxic or nanomaterial samples. The electronic system is protected with a universal power adapter and internal voltage regulation, ensuring consistent performance regardless of the regional power standard.

In summary, the KS-GPM-8 agate grinding mill represents a sophisticated solution for sample preparation in high-precision applications. Its use of agate components for grinding, combined with automation, safety, and inert-atmosphere compatibility, makes it an indispensable tool for laboratories focused on purity, reproducibility, and efficient sample processing. Whether used in academic research, industrial development, or environmental analysis, this model is built to deliver results with confidence and consistency.
