The MVT™apparatus consists of one heavy, aluminum heating block with 26 test tube holder holes (also model with 10 holes is available as a standard). Each tube is covered with an individual lid equipped with a small hook. The indicator paper is then conveniently hung on the hook which is placed inside the tube when the lid is secured. OZM Research™ supplies the highest quality of indicator paper--guaranteed to meet US Navy specifications and is currently being utilized and accredited by the USA Military.
The glass test tubes (with the tested samples and indicator paper) are inserted into their holders in the heating block. The temperature of the block is administered by a control unit which is comprised of an operational controller and a limit controller. The limit controller operates an independent alarm circuit which halts the heating process if temperatures were to accidentally increase above specified safety limits. Calibrated digital thermometers may be used to correct and control the temperature of the heating block.
