Grocera

99.7% High Alumina Labware

High Temperature Labware

Pure ceramic material for analytical analysis plays vital role due to extreme high temperature, high thermal shock, high mechanical strength, high corrosion resistance, good electrical insulation properties with high purity.
Material :

1- Alumina up to 99.7% Al
:2- Zirconia 3YPSZ

Products : Crucibles from 1 ml to 1000 ml. in Cylindrical, Conical, Rectangle, Square, Micro crucibles, lids, Dishes, Plates, Tubes, Rods, combustion Boats Muffles, Ceramic stirrers, Ignition dishes, Jar for Jar mill, Porous ceramics etc.

Grocera Labwares is made of 99.6% pure aluminum oxide. Highly resistant to chemical attack, this alumina-ceramic ware is especially useful to chemists, metallurgists and other involved in high temperature work demanding contamination-free results.

High Alumina ware is highly refractory, meant for use in reducing and oxidizing atmospheres. It is inert in hydrogen and carbonaceous atmospheres and offers high resistance to alkalies and other fluxes. Suitable for glass melting.

Recommended for use with refractory metals such as Molybdenum, Platinum, Rhodium, Tungsten, Tantalum and Iridium. High-Alumina Labware temperature change rate should not exceed 150 °C/hour.
