NTB Labwares in AL995, AL98, AL96, Zirconia, Mullite & Quartz

NTB CERATUFF Labwares are used in high temperature, laboratory applications like Crucibles, Boats, Trays, etc. for reacting chemicals, melting metals, carbon & sulphur analysis, and handling corrosive liquids. NTB CERATUFF labware are used by chemists, metallurgists and others involved in high temperature, contamination-free applications.

NTB Labware in recrystallized 99.7% Alumina or Stabilized Zirconia is highly resistant to alkaline & other fluxes, and used for melting glass and refractory metals like molybdenum, platinum, rhodium, tungsten. NTB One-End Open Thermocouple Tubes & Both-End Open Annealing tubes protect sensors in high temperature and highly corrosive environments like chemical baths & replace expensive carbon sheets in heaters. NTB Mullite & Fused Silica (Quartz) crucibles are thermal shock & corrosion resistant. These are used for carbon and sulphur analysis in Metallurgical, Chemical, Rubber and Mining Industries.
