Muffle Furnace SH Scientific SH-FU-14MG 14L Benchtop 1200°C Max

Description

Product Overview

The SH Scientific SH-FU-14MG is a high‑performance benchtop muffle furnace engineered for laboratory environments that demand precise temperature control and reliable repeatability. With a 14‑liter internal chamber (250 mm × 350 mm × 160 mm), the unit can accommodate a wide range of sample sizes, from small crucibles to larger trays, making it suitable for diverse applications such as annealing, sintering, combustion analysis, and ashing. The furnace reaches a maximum temperature of 1200 °C, while the recommended continuous operating temperature stays below 1000 °C to preserve component longevity. A double‑wall housing design minimizes external surface temperature, keeping the outer shell at a safe 29–30 °C even when the chamber is heated to 800 °C, thereby reducing the risk of accidental burns and simplifying integration into crowded lab spaces. The heating system utilizes a 4.1 kW ceramic heater that distributes heat uniformly from four sides, achieving temperature uniformity within ±2.5 % across the chamber. This uniformity is critical for processes that require consistent thermal exposure, such as material densification and polymer curing. The furnace is powered by a 220 V hard‑wired connection, delivering stable energy input for continuous operation. Its robust construction, weighing 144 lb (≈65 kg), combines a sturdy metal frame with a high‑temperature‑resistant ceramic interior, ensuring durability under demanding thermal cycles.

Usage

Designed for research laboratories, quality‑control facilities, and educational institutions, the SH‑FU‑14MG excels in environments where precise thermal treatment is essential. Typical use cases include metal alloy heat‑treatment, ceramic sintering, polymer curing, battery electrolyte preparation, and analytical ashing of soil or water samples. The furnace’s programmable 45‑step controller allows users to create custom temperature ramps, holds, and cooldown profiles, enabling complex thermal cycles without manual intervention. Its exhaust air outlet positioned on the chamber head facilitates effective outgassing, which is particularly valuable when processing volatile or polymeric materials that could otherwise release contaminants into the lab atmosphere. The compact benchtop footprint (approximately 600 mm × 500 mm × 400 mm) permits placement on standard laboratory benches, while the swing‑door design provides easy access for loading and unloading samples. The unit’s low external surface temperature and insulated housing make it safe for operation in shared spaces, and the integrated safety interlock ensures the door cannot be opened while the furnace is above 200 °C, protecting users from accidental exposure.

FAQ

What materials can be processed in this furnace?

The SH‑FU‑14MG is suitable for metals, alloys, ceramics, polymers, plastics, and battery electrolyte compounds. Its exhaust outlet also supports outgassing of volatile substances, making it versatile for a wide range of research and industrial applications.

How does the temperature uniformity compare to other furnaces?

With a four‑side heating system and double‑wall insulation, the furnace maintains temperature uniformity within ±2.5 % across the entire chamber, which is superior to many standard laboratory furnaces that often exhibit variations of ±5 % or more.

Is the furnace safe to operate continuously?

Yes. The furnace is designed for continuous operation up to 1000 °C, with built‑in safety interlocks that prevent door opening above 200 °C and automatic shutdown in case of overheating or power irregularities.

Can the temperature be programmed remotely?

The built‑in 45‑step controller can be accessed via the front panel interface. For remote operation, SH Scientific offers optional communication modules that allow integration with laboratory information management systems (LIMS) and external PC control.

What warranty and service options are available?

Standard warranty covers one year of parts and labor. Extended warranty plans and on‑site calibration services are available through SH Scientific’s support network, ensuring minimal downtime and sustained performance.
