The new DHC-6T dry heat transdermal diffusion cell system has many advances and cost saving features. This new dry heat system does not use a water circulator, therefore saving lab space, cost, and testing preparation. The thermo-controlled housing design produces more efficient and evenly distributed temperatures to each cell. DHC-6T is also equipped with a bronze cover for light sensitive products. Franz cells are very costly as they are handmade and can break by simply dropping them. Logan Instruments Corp. has developed a Dry Heat Cell using precision glass and Teflon parts to create a new economical cell for the DHC-6T, such cells are designed to change glass tube lengths for different media volumes.
