1.Melting Point Apparatus - It is usable to estimate the Melting Point of chemicals, Pharamaceuticals, Food Etc., This is very useful to determine the melting point if any subsatance. Max Temp. up to 3500C. Consist with aluminium cylindrical block for heating, Radial holes admits a thermometer and glass capillary. Temp. Controlled by energy regulator. Regulator fitted ti the unit and with high, low heat switch. 2. ESCR Apparatus- E.S.C.R. Apparatus is used for determination of suceptibility of ethylene plastics to environmental stress cracking when subjected to certain conditions. Bent specimens of the plastics each having a controlled imperfection on the surface are exposed to the action of a surface active agent, oils or detergent. The proportion of the total number of specimens that crack in a goven times is observed.
