Today's analytical laboratories require versatile crucibles that accommodate a full range of solutions and processes, from strong alkali fusions employed to render refractory samples soluble, to acid dissolution and high-temperature ashing. More than three decades of experience in refractory metals makes MTI the premier resource of innovative and adaptable products for your laboratory using a diverse selection of metals and alloys to perfectly fit your needs. In fact, research has shown that once a laboratory begins using MTI crucibles, they experience greater efficiencies, long-term durability, and lower costs, making them an indispensable part of its analytical equipment.

Tantalum

Tantalum is one of the most corrosion-resistant metals available, as it resists most acids and biological specimens. It is an excellent material for analytical laboratory work. (Read more...)

Molybdenum

Molybdenum resists most non-oxidizing acids and provides an effective barrier to many molten metals. It enables you to perform high-temperature fusions in a vacuum or inert atmosphere at temperatures approaching 2000˚C. (Read more...)

Crucible Cleaning Kits

Crucible cleaning kits contain all the material you need to safely clean most types of laboratory crucibles, including zirconium, nickel, molybdenum, tantalum and platinum, as well as ceramics and glass. Kits also include a supply of liquid cleaner, a variety of abrasive materials, and complete instructions.

Pour Plates

Metal Technology’s pour plates provide an excellent heat sink for quenching fusions or for pouring fluid melts for solidification into buttons for rapid and easy handling. Standard pour plates are available in copper or stainless steel. We can also create them using the same metals as your crucibles.

Vanadium Sample Cans

Finally a superior sample can solution for neutron-powder diffraction and neutron-scattering experiments. Developed in cooperation with NIST,  MTI sample cans are transparent to neutrons, making them an excellent choice for your experiments. Using a closed-end design, you can irradiate the entire sample without needing to mask off an open end. Sample cans are available in several diameters and lengths to optimize signal/noise ratios. A titanium alloy flange is also available and offers a thermal expansion coefficient very near to vanadium’s. Standard sizes range from 0.250” diameter to 0.625” diameter. Lengths are from 2.00” to 3.00”. The standard wall thickness is 0.006”.
Price List

MTI’s vanadium sample cans are:

• Seamless
• Virtually indestructible and resistant to holes
• Available with titanium flanges and aluminum caps
• Adaptable to a wide range of temperatures
• Manufactured with a groove in the flange for O-ring, or indium seal
• Available in custom materials, diameters and lengths
