Product Description
                                                                           Textile Formaldehyde Tester
Introduction:
textile formaldehyde tester is used to test formaldehyde content in various fabrics. 

textiles formaldehyde tester fine-grained textiles are extracted in a water bath at 40 ° C for a period of time. Formaldehyde extracted from the fabric is absorbed by water and the extract is developed with acetylacetone (yellow). The yellow compound has a visible Selective absorption, so the use of colorimetric analysis method can be measured in the textile formaldehyde formaldehyde content of samples tested.
