Muffle Furnaces

Introduction to Muffle Furnaces

Muffle furnaces are specialized heating equipment used for the high-temperature treatment of material samples in the laboratory, serving applications such as ash analysis, determination of loss on ignition (LOI), and inorganic or organic material testing. The equipment provides a stable, uniform temperature environment to perform thermal reactions and sample ashing.

When choosing a muffle furnace, users should consider the maximum temperature suitable for the application, such as 1100°C, 1150°C, or 1200°C, along with a chamber volume that accommodates the sample load, such as 7,5 liters or 9 liters. In addition, flap door or lift door designs are also important criteria to ensure operational safety for technicians. Hoa Viet currently supplies muffle furnaces and ashing furnaces from manufacturers Nabertherm (Germany) and Yamato (Japan).

Which brands of muffle furnaces does Hoa Viet supply?

Hoa Viet currently distributes laboratory muffle furnace lines from two manufacturers: Nabertherm (Germany) and Yamato (Japan).

What is the difference between the lift door and flap door designs on Nabertherm furnaces?

The flap door series allows the door to open downwards, creating a convenient working surface. Meanwhile, the lift door series moves the door upwards, keeping the hot side facing away from the operator to enhance safety during high-temperature handling.

What is the maximum temperature range of the furnace lines at Hoa Viet?

Depending on the model and testing requirements, current furnace lines feature maximum temperatures of 1100°C, 1150°C, or up to 1200°C.

What applications are the LVT ashing furnace series typically used for?

The LVT muffle furnace series is specially designed for ashing applications, loss on ignition (LOI) testing, and processing inorganic as well as organic material samples.
