Tewitro® TW 24

Tewitro® - Messung in bis zu 24 Zellkulturen

Transepidermal Waterloss Measurement in up to 24 Cultured Skin Samples Simultaneously

The Tewitro® TW 24 is the only device to measure the water evaporation from cultured tissue sets (wells in a plate with medium) in up to 24 wells simultaneously with the worldwide most used “open chamber” measurement of the Tewameter®.

Indispensable tool for safety, sensitivity and efficacy measurements to avoid using animals or volunteers.

Whenever the barrier is damaged, the evaporation rate will increase immediately. Also for claims related to barrier improvement/enhancing, tests on cultured cells are needed, as products meant to keep the barrier intact or to even improve it, can be detected by a stable Transepidermal Water Loss (TEWL).

Fully equipped, the Tewitro® TW 24 can be used in 24 wells plates (6x4). The probe features 6 slots with 4 measurement inlets each, but is also available as single rows of 1 slot with 4 measuring inlets (respectively for 8, 12, 16 or 20 inlets), depending on the used well plate size.

The convenient and organized software offers 24 TEWL-values (one for each measurement inlet), with two different adjustable averages and their respective standard deviations as well as the possibility of displaying and saving the RH and temperature value for the upper and lower sensor pair for each measurement inlet (2 x 24) separately. Graphical view for each measurement inlet with one click.
