250ml Plastic Hydrometer Test Jar Measuring Cylinder for Beer Homebrew (C6498)
Check the alcohol content of your brew from time to time to know when the fermentation is done and your beer is ready to be bottled.
Take a small sample in this hydrometer jar, dip the hydrometer and note the reading. This convenient, easy to use and clean testing jar is made of durable plastic.
The measuring jar is long and narrow which allows the hydrometer to be dipped completely and requires much less sample quantity than in a beaker.
Available in two sizes of 100 and 250 ml.
