Cellulose tests

Tensile strength testing was performed using 0.05 wt% of selected experimental agents on dry cellulose. Testing results are provided in Table 1. 

Any substance or mixture which, in the 1 1 mixture, by mass, of substance (or mixture) and cellulose tested, spontaneously ignites or the mean pressure rise time of a 1 1 mixture, by mass, of substance and cellulose is less than that of a 1 1 mixture, by mass, of 50% perchloric acid and cellulose ...

The dipstick test for total protein includes a cellulose test pad impregnated with tetrabromphenol blue and a citrate pH 3 buffer. The reaction is based on the protein error of indicators phenomenon in which certain chemical indicators demonstrate one color in the presence of protein and another in its absence. Thus tetrabromphenol blue is green in the presence of protem at pH 3 but yellow in its absence. The color is read after exactly 60s and the test has a lower detection limit of 150 to 300mg/L, depending on the type and proportions of protein present. The reagent is most sensitive to albumin and less sensitive to globulins, Bence Jones protein, mucoproteins, and hemoglobin.
