Types

The manual DHC-6T, DHC-6TD, DHC-6TD without temperature control, DHC-6TA, and FDC-6TA systems from Logan Instruments offer a reliable solution for determining the permeation rate of semi-solid dosage forms and cosmetic products such as gels, lotions, ointments, plasters, or sunscreens. Depending on the application, versions with dry heating or water jacket heating are available – optionally with temperature monitoring, variable tilt function, or upgradeable to automated sampling.

The robust construction, precise temperature control and user-friendly cleaning make the Manual Transdermal System the ideal choice for research facilities, development laboratories and quality control.
