A foldable space heater comprises a lower housing, a telescopic pole, and an upper housing. The upper housing connected with the telescopic pole via a first hinge joint. The lower housing connected with the telescopic pole via a second hinge joint. An electric wire passed through the lower housing towards the upper housing via the telescopic pole to avoid tripping of the electric wire. The upper housing includes a heating element, and a fan. The heating element connected with the electric wire to convert electric energy into heat. The fan ventilates the radiations associated with the heat. The telescopic pole makes the foldable space heater extendable and retractable. The first hinge joint and second hinge joint makes the foldable space heater collapsible. A user interface provided to operate the foldable space heater. The foldable space heater also equipped with wireless charging.

An automatic cleaning assembly for an analytical furnace is detachable from the filter chamber above the combustion tube. The cleaning assembly includes a rotating brush which is lowered through the filter chamber and into the combustion tube while a vacuum is drawn through the lower seal of the combustion tube. This results in a higher vacuum pressure differential and improved flow rate for removing dust from the filter of the furnace and the combustion tube.

A graphitization furnace includes: a first electrode; a second electrode disposed so as to face the first electrode; a first energized heating element provided on a surface of the first electrode facing the second electrode; and a second energized heating element provided on a surface of the second electrode facing the first electrode. The first and second energized heating elements are configured to allow to be disposed therebetween, an object to be processed. The graphitization furnace is configured to heat and graphitize the object to be processed disposed between the first and second energized heating elements by energizing between the first and second electrodes.
