URINE ANALYSIS APPARATUS 



14060. ALBUMINOMETER, Esbach's, for the quantitative determination of albumin in urine; gradu- 

 ated to read grams of albumin per liter of urine. Complete with directions $0.65 



14062. ALBUMINOMETER, Esbach's, with pointed bottom, for testing small quantities, on foot 1.00 



14064. ALBUMOSCOPE (Horismascope), for the detection of albumin in urine ith nitric acid. With 

 this instrument the nitric acid comes in contact with the urine in full strength, thus rendering 

 the test much more delicate than ordinarily, 1/60 per cent, of albumin being detectible. Com- 

 plete with directions for use 1.25 



14066. FEHLING'S SOLUTION, tablet form for use in Urine Analysis, sufficient to make one ounce of 

 solution 25
