Laboratory furnaces: A complete guide to choosing between fiber and ceramic furnaces
🔎 What is a laboratory furnace? Laboratory furnaces are electric thermal equipment used in processes such as: They are known for their robustness, thermal uniformity and availability at different maximum temperatures (e.g. 1100 °C, 1200 °C and 1300 °C). 🔥 Muffle furnaces vs electric laboratory furnaces Although in many catalogs these terms seem different, in practice: ✅ A muffle furnace is a type of electric furnaceThe term muffle refers to an insulated inner chamber that protects the heating elements and prevents contact between the heating elements and the samples. This allows for cleaner and more uniform thermal environments. 📌 In the furnaces category on our website, you can find electric muffle furnaces, designed to offer: 🧱 Laboratory furnaces: differences between fiber and ceramic chamber Choosing between these two options depends on the required thermal process. 📌 Fiber chamber ✔ Constructed from a one-piece thermal fiber block.✔ Heating elements are integrated in or on the fiber.✔ Low thermal mass → faster heating and lower energy consumption.✔ Well suited for 1100 °C, 1200 °C and 1300 °C depending on model.✔ Clean environment, with less heat loss. 👉 Recommended for: 🔥 Ceramic chamber ✔ Constructed with dense ceramic bricks.✔ Can have the resistors visible or partially accessible depending on design.✔ Higher thermal inertia → takes longer to heat up, but offers prolonged stability.✔ Very useful in long processes at high temperature. 👉 Recommended for: 📊 Comparison: Fiber vs ceramic chambers Feature Thermal fiber Ceramic Heating time 🔼 Fast 🔽 Slower Energy consumption 🔼 More efficient 🔽 Less efficient Thermal uniformity 🔼 High 🔼 High Thermal inertia 🔽 Low 🔼 High Access to heating elements Integrated in fiber Visible or accessible Recommended for Repeated and fast cycles Long and stable processes Typical temperatures Up to 1300 °C Up to 1300 °C 📈 Which temperature to choose? 1100 °C, 1200 °C or 1300 °C The choice of maximum temperature depends on your application: 📊 Temperature controllers: basic vs. with programmable ramps All furnaces come standard with a non-programmable OMROM basic temperature controller.However, you can optionally choose programmable controllers that allow: ✅ Create heating and cooling ramps.✅ Program complex profiles with multiple steps.✅ Store and repeat thermal cycles with precision.✅ Facilitate traceability in critical processes. This is especially useful for applications in: ✨ Conclusion To select the ideal furnace you should consider: ✔ Type of chamber (fiber or ceramic).✔ Maximum temperature you need to reach.✔ Whether you need thermal profile programming.✔ The type of process and its duration.
