ordinary cream bottle, or where shorter wide-mouthed 
50% bottles are used.

A cream bottle commonly used is the Winton 30% 
bottle, shown in Fig. 10. With this bottle only 
half a sample (9 grams) of rich cream can 
be used. To the half sample of cream a scant 
half-measure of acid is added, and the testing 
finished in the usual way. What is better, 
however, is to add to the nine grams of cream 
approximately 9 c.c. of water and then use 
the full amount of acid. Obviously where only 
half a sample of cream is used in the ordinary 
bottle, the test must be multiplied by 2 to get 
the correct reading. 
Lately, a small bore cream bottle (Fig. 29) 
HI) has been placed upon the market in which only 
| half a sample of cream is used, but which gives 
a reading for a full sample. This does away 
Fig. 29—Nine with multiplying tests by 2 when only half a 
gram cream 
bottle.
