Pulverizing Bowls
Pulverizing bowl: also called pulverising mill grinding bowl, pulverizer mill bowl. It is a grinder that grinds coarse material into fine powder. When working, put the grinding bowl into the laboratory sample pulverizer or vibration grinder card slot. The motor drives the grinding bowl to eccentrically vibrate. After 2-6 minutes of work, the material can reach 80-300 mesh for testing.
Pulverizing bowls available in various materials and capacities

The material of the ring and puck bowl includes carbon steel, high manganese steel, alloy, tungsten carbide, and chrome steel.
The series of grinding bowls of GLS has good wear resistance and impact resistance. A unique range of bowls from 40 to 5000g nominal capacity. The “bowl and disc” style grinding head forms the core of GLS’s extensive bowl range.
We delivers this high-capacity, high-production bowl to the sample preparation market over 10 years. Today it is still the preferred bowl of choice in most of the world’s leading commercial testing laboratories.
These bowls are of through-hardened steel construction for optimum life. They are available in 640, 800, 1600, and 3500g nominal capacities. GLS “ring and puck” style bowls are available in the smaller 50, 100, 125, 300 & 400cc nominal capacities. These too are of through-hardened steel construction, with tungsten carbide available in the 125cc size. This innovative crushing and grinding configuration provide rapid preparation of large samples up to 5000g in nominal capacity.
Application range: metals with certain hardness, non-metals (coal, rock, coke, ore, granular materials), and other minerals.

Zirconium Crucibles [low form]
Zirconium exhibits superb corrosion resistance in most organic and inorganic acids, salt solutions, strong alkalis and a few molten salts.
The passive oxide film (corrosion barrier) is stable in both reducing and oxidizing conditions. Zirconium is excellent in both acid and base solutions.
The temperature limit for use in air is
about 450˚C to 500˚C.
Safety Goggles
Safety goggles can provide special eye protection for specific work and environments. Safety goggles are your ideal choice when you need to minimize the risk of liquid splash, corrosive vapor, air dust and solid particles’ high-speed impact. Safety goggles are mainly divided into three types: anti-solid debris, anti-chemical solution and anti-radiation.
Bullion Blocks
Magnesia Bullion Block is a shallow, porous block with multiple holes, made from pure Magnesite, in which gold or silver can be refined or assayed by melting with a blast of hot air which oxidizes lead or other base metals.
Bullion Blocks are specifically designed to stand longer in the extreme heat of furnaces. These blocks are great heat conductors and high efficient to use.
These do not not crack or break over the course of time as well as demands no maintenance. Moreover, these Blocks are extremely durable and available in various specifications.
Magnesia Cupel
Cupel is a shallow, porous crucible with approximately 96% magnesia. It is especially used to separate gold, silver, and precious metals from lead buckles in the process of Pb-Fire assay. By using high-quality raw materials and scientific formulas, GLS’s fire assay magnesia cupel has a smooth surface, high mechanical strength, and will not crack and pit during high-temperature cupellation.

Zirconium Crucibles [straight wall]
Zirconium is our most effective crucible material for fusions using sodium carbonate or sodium peroxide. It is an excellent low-cost replacement for platinum. And, based on an average of 100 fusions per crucible, it is more cost effective than less expensive porcelain or steel crucibles.
Other advantages of zirconium are its complete resistance to the action of most solvents of all concentrations such as nitric, hydrochloric, sulfuric and perchloric acids.
This allows the fusions to be dissolved out of the crucible completely with little or no contamination of the sample. Alkaline solvents such as ammonium hydroxide, acetate sulfide, carbonate and (Na, K) hydroxide, sulfide, carbonate and cyanide are also without effect.
