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.
Crucible Tumbler
GLS’s crucible tumbler is a new type of forward and reverse rotating mixing equipment. The crucible tumbler is mainly used for batch mixing of fire assay mineral samples and fluxes. The device can mix up to 50 fire assay crucibles at a time. This significantly improves the efficiency of laboratory sample preparation and reduces manual operations. It is one of the necessary equipment for fire assay laboratory.
The lengthy time required for fire assaying of gold, silver and precious metals can often be compensated for by the simultaneous analysis of a large number of samples. A typical fire assay laboratory is usually equipped with several furnaces and cupellation furnaces, each capable of collecting multiple samples. Therefore, GLS’s Multiple Sample Load Forklift, Crucible Tumbler and other equipment have greatly improved the efficiency of laboratory sample preparation and load-and-unload.
Fire Assay Crucible
Gold Smelting Crucibles As Name of Fire Assay Crucibles,have a higher than normal resistency to cracking under fire assay conditions. Our crucibles and refractory products are used in laboratories throughout international marketplace. Our Crucibles can be used for 3-5 times. We have a variety of shapes and sizes available to cater to specifications required.
Furnace Chamber And Tile
GLS has various shapes of horseshoe-shaped furnaces, furnace tubes, electric furnace tile plates, rails, large-span muffle furnaces, etc. Used in various heat treatment furnaces, such as muffle furnaces, enamel sintering furnaces, diffusion furnaces, slats of various kilns, flameproof materials, etc.
Blade Hammer Crusher
● Suit to both stalk type fiber material and mineral type granular material.
● Welded steel crushing cavity can avoid easy crack and material holdup problems.
● Fully sealed cabinet design offers safe and dust free operation.
● Full width hammer heads crush materials in full section and avoid problems of blocking working cavity and sample holdup.
● Crushing large moisture samples without moisture lose and with uniform output and high efficiency.
● Low noise and easy moving with wheels.
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.
Cupellation Furnace
• Easy to maintain and operate.
• Door panel for easy access to transformer.
• Fast and accurate temperature control ensures consistent and stable temperature.
• Built to industrial standards and compatible with multipour and multiload system.
• Pneumatic rising door operated by food pedal reduces thermal radiation hurt and risk to operator.
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.
