DermaLab Single by Cortex Technology

A line of laboratory single parameter instruments sharing the same LabView based software platform. Comes complete with probe, interface unit and software and connects to PC’s or tablets running Windows. Available parameters: TEWL, elasticity, hydration, skin high res. ultrasound and subcutane ultrasound visualization.



Popular and cost-effective solution

For those with specific skin measuring needs.

In addition to the well-known parameters for measuring TEWL, elasticity and hydration. The DermaLab Single unit line of probes also features the 10 MHz and 20 MHz high resolution ultrasound probes. The 20 MHz for measuring of skin thickness as well as skin structure and the 10 MHz for visualizing subcutaneous layers and structures with a maximum of 50 mm penetration.


Subcutaneous ultrasound

The DermaLab subcutane ultrasound unit is taking the DermaLab Series ultrasound technology one step further. This dedicated scanner visualises tissues in the subcutaneous space to a depth of 50 mm in order to assess the effects of fat reduction procedures in the abdominal area as well as on the thighs.
Good resolution, high penetration and ease of operation are the keywords describing this device, which comes as a complete package including main unit, probe and application software ready to be installed on a Windows PC or tablet.
