The main aim of the study is develop a cost effective device to detect glucose, protein and specific gravity of substance. A glass capillary tube with diameter 0.5mm and height 100mm was utilized. Height rise for different well-known fluid for that capillary tube is marked. The Benedict's reagent and Coomassie brilliant blue G250 was tested on cotton thread towards its inert state for these two reagents. At the opposite end of the tube a cotton thread was inserted which contended Benedict's reagent and Bradford Reagent (Coomassie brilliant blue G250) socked and dried on the thread. The device was tested the glucose sensitivity and protein sensitivity. This is a multipurpose device and can also be used to detect diabetes and kidney malfunction. Moreover, it can be applicable to circle round the cause which may kill the person by measuring blood specific gravity in its height rise scale. Moreover, it is the fastest, handy and most economic device which can find whether there is any chemical substitute for glucose or whether the water is pure for drinking purpose.
