About This 1300°C LOI Furnace 370 x 650 x 370 MM Chamber

LOI stands for "Loss on Ignition." This furnace is specifically used to heat a sample to a high temperature (typically 1000°C) to drive off volatile components like water, carbonates, and organic matter. The working principle involves weighing a sample before and after ignition in a controlled atmosphere (usually air); the weight loss percentage is the LOI. Its purpose is an essential analytical technique in ceramics, geology, soil science, and cement manufacturing to determine the composition and quality of raw materials and products.

Equivalent chamber references: 370 x 650 x 370 MM, 37 x 65 x 37 CM and 14 x 26 x 14 INCH. Buyers searching for 1300°C LOI Furnace 370 x 650 x 370 MM; LOI Furnace 1300°C 370 x 650 x 370 MM; LOI Furnace 370 x 650 x 370 MM 1300°C; 370 x 650 x 370 MM 1300°C LOI Furnace; 1300 Degree LOI Furnace 370 x 650 x 370 MM; LOI Furnace 1300 Degree 370 x 650 x 370 MM can verify the same physical chamber on this canonical product page before requesting price, GST invoice, packaging and delivery.

Trutherm manufactures 1300 Degree Celsius (°C) LOI Furnace 370 x 650 x 370 MM Chamber for buyers who search by exact machine type, chamber size and 1300°C temperature rating. This page is specific to the MM dimension version, so the chamber size is presented in the unit normally used in the buyer's drawing, tender or purchase request.

This configuration is suitable when the sample load must fit a 370 x 650 x 370 MM chamber with usable chamber volume of 89 litre, approximate power load of 17.7 kW, rectangular - tall chamber profile. It is commonly selected for laboratory, QC, metallurgical, ceramic, pharmaceutical and industrial heat-treatment work requiring stable heating and repeatable process conditions. Typical use includes general laboratory and industrial heat-treatment applications requiring stable, repeatable temperature control.

Uniform chamber heating and a simple door-loading design make a muffle furnace straightforward to standardise across multiple operators and shifts.

Where sample volume and process type vary week to week, a general-purpose muffle furnace avoids the cost of maintaining several process-specific furnace types.
