The Labthink HST-H3 is a laboratory heat seal tester designed to determine the optimal temperature, pressure and contact time conditions for heat-sealable films and packaging materials.<\/p>\n
Its independently controlled jaw system allows sealing conditions to be reproduced accurately and uniformly. This facilitates the selection of suitable parameters for production, quality control, and research and development.<\/p>\n
Key Features<\/strong><\/p>\n \u2022 Digital P.I.D. temperature control. Applications<\/strong><\/p>\n Suitable for plastic films, composite films, coextruded materials, metallized films, aluminum sheets and laminates used in flexible packaging.<\/p>\n With special configurations, it also allows testing of cup lids, flexible plastic tubes and materials with smooth or textured sealing surfaces.<\/p>\n
\n\u2022 Temperature range from ambient to 250 \u00b0C.
\n\u2022 Temperature accuracy of \u00b10.2 \u00b0C.
\n\u2022 Adjustable sealing time from 0.5 to 999.9 seconds.
\n\u2022 Sealing pressure from 0.05 to 0.7 MPa.
\n\u2022 Independent control of the upper and lower jaws.
\n\u2022 Standard sealing area of 330 \u00d7 10 mm.
\n\u2022 Uniform heating across the entire sealing surface.
\n\u2022 Stable pressure provided by pneumatic cylinders.
\n\u2022 Manual or foot pedal operation.
\n\u2022 Design incorporating protection against burns.
\n\u2022 Software for storing, exporting and printing results.
\n\u2022 RS232 connection for data transfer.<\/p>\n
