VACUUM OVEN 



2645/1 "The Standard F. A. C. Vacuum Oven has been designed with the idea of 

 affording a simple and compact vacuum oven which will give as uniform tem- 

 peratures as possible on the shelf. It consists of an iron casting of rectangular 

 sections with hinged front door, which is accurately counterpoised. The door 

 is made tight by a gasket and which can be lowered on opening the oven so 

 as to form a shelf on which samples may be rested. The oven contains but 

 one shelf which is heated from above as well as below by means of resistance 

 coils. Several thermometer holes are provided in order to ascertain definitely 

 the temperature at different points on the shelf. ' The entire oven is supported 

 by means of a 4" standard pipe which screws into the base of the oven and 

 which in turn is supported by being screwed into a blind flange of suitable 

 diameter which rests on the floor or work table."

STANDARD THERMOMETER (TITER) 



2646/8 "The thermometer is graduated at zero and in 1/10 from 10C to 65C, wiilj 

 one auxiliary reservoir at the upper end and another between the zero mail* 

 and the 10 mark. The cavity in the capillary tube between the zero mark 

 and the 10 mark is at least 1 cm. below the 10 mark, the 10 mark is 3 or 

 4 cm. above the bulb, the length of thermometer being 37 cm. overall. The 

 thermometer has been annealed for 75 hours at 450C, the bulb is of Jena 

 normal 16" glass, or its equivalent. Bulb is about 3 cm. long and 6 mm. in 

 diameter. Stem of thermometer is 6 mm. in diameter and made of the best 

 thermometer tubing, with scale etched on the stem. The thermometer musl 

 be certified by the U. S. Bureau of Standards.
