What Happened When I Tried the Barnstead Small Benchtop Muffle Furnaces, Type 1300 and Type 1400, Barnstead International FB1415M Type 1400 Furnaces Furnace, 120V, 1500W
The Barnstead Small Benchtop Muffle Furnaces, Type 1300 and Type 1400, Barnstead International FB1415M Type 1400 Furnaces Furnace, 120V, 1500W are compact, high-temperature furnaces designed for a variety of laboratory applications. Manufactured by Thermo Scientific, these furnaces offer precise temperature control and a durable design for reliable performance.
My work in metallurgical analysis often requires ashing samples and heat treating small parts. I needed a reliable and compact furnace for these tasks, especially one with accurate temperature control.
The furnace arrived well-packaged, and my initial impression was of a robust, well-constructed unit. The refractory cement construction and the insulated door felt solid, assuring me of longevity and safety.
I considered other benchtop furnaces from Carbolite Gero and Nabertherm, but the Barnstead stood out due to its thermocouple break protection and the circulating air-injected heat system (in the Type 1400 model). The Thermo Scientific brand also has a solid reputation, which influenced my choice.
I was excited to get started, hoping that it would streamline my sample preparation process. The promise of consistent temperature and operator safety definitely piqued my interest.
Real-World Testing: Putting Barnstead Small Benchtop Muffle Furnaces, Type 1300 and Type 1400, Barnstead International FB1415M Type 1400 Furnaces Furnace, 120V, 1500W to the Test
First Use Experience
I initially tested the Barnstead Type 1400 in my lab to ash organic samples for soil analysis. The digital control was straightforward to use, and I appreciated the door safety switch.
The ambient lab temperature was around 70°F, and I ran the furnace at 500°C to ensure complete ashing. The furnace heated up quickly, and the temperature remained very stable throughout the process.
The ease of use was a pleasant surprise; I didn’t need much time to understand the controls. I was, however, a little concerned about the external temperature of the unit during operation.
Extended Use & Reliability
After several weeks of consistent use, the Barnstead furnace has proven to be a reliable workhorse. There are no signs of wear and tear on the refractory cement or the heating elements.
Cleaning is straightforward; I simply wipe down the interior with a damp cloth after each use. Compared to my previous furnace, the Barnstead offers far more consistent temperature control and faster heating times, vastly improving efficiency.

Specifications
-
The Barnstead Small Benchtop Muffle Furnaces, Type 1300 and Type 1400 have a maximum temperature of 1100°C (2012°F). This high temperature range is essential for various high-temperature applications.
-
The Type 1300 has chamber dimensions of 10.2W x 9.5H x 11.4D cm (4 x 33/4 x 41/2“). This size is suitable for smaller samples and limited bench space.
-
The Type 1400 features larger chamber dimensions of 12.7W x 10.8H x 15.2D cm (5 x 41/4 x 6″). The larger capacity is more adaptable to varying sample sizes.
-
The overall dimensions for Type 1300 are 20.3W x 31.8H x 21.6D cm (8 x 121/2 x 81/2“), and for Type 1400, they are 25.4W x 36.8H x 27.9D cm (10 x 141/2 x 11″). These compact footprints are vital for labs with limited space.
-
Type 1300 weighs 6.1 kg (13.5 lbs.), while Type 1400 weighs 10 kg (22 lbs.). The relatively light weight allows for easy repositioning within the lab.
-
Both models require 120 or 240V, 50/60Hz electrical input, with the reviewed model being 120V, 1500W. This is compatible with standard lab electrical setups.
-
The refractory cement construction enhances the durability of the unit, preventing contaminant penetration. This extends the longevity of the heating elements.
-
Type 1400 also has a circulating air-injected heat system with padded pebbles in the inlet well. This ensures more uniform heat distribution within the chamber.
These specifications are critical because they directly affect the furnace’s suitability for specific applications and its longevity under constant use. The high maximum temperature and robust construction make it suitable for diverse applications.
