INSTANT IGNITION of Solid Samples
Typical laboratory installation. A Lindberg Volumetric Carbon Determinator operating with a Lindberg "H-F" Combustion Unit
The Lindberg " H F " Combustion Unit is revolutionizing carbon and sulphur determinations in laboratories throughout the country. Ready for instant use—instant temperatures above 3000° F.— for steel, cast iron, alloys, or stainless samples—volumetric or gravimetric!
A high frequency
unit specially designed for the
laboratory
• Shorter tubes advantageous for volumetric method. • No elements to burn out or limit temperatures. • Heats nothing but the sample. • Eliminates excess heat from the laboratory. • Inexpensive "cupelet" holds full factor weight for carbons. • Small andcompact-13'wide-28H"high-17"deep.
• Ready in the morning in 57 seconds—instantly from then on. • 90% less power consumption (maximum input 0.125 KW idling). • Class combustion tube provides visability of operation. • Combustion tubes at half the cost, last many times longer.
