100mL Test Tube with 1mL Graduations Polypropylene
100mL Polypropylene Measuring Cylinder — Trial Jar for Hydrometer & Alcometer Use
This 100mL polypropylene measuring cylinder is the standard trial jar used by home brewers, winemakers, and distillers for taking hydrometer and alcometer readings. Tall and narrow in design, it holds just enough liquid to float a hydrometer or alcometer freely, giving you a stable, accurate reading without wasting your brew.
Why You Need One
Hydrometers and alcometers need a dedicated container to work correctly — you can't float them in a fermenter or bottle. This trial jar is the right size and shape for the job: tall enough to allow full flotation, narrow enough to minimise the sample volume needed, and graduated in 1mL increments so you can measure liquid additions precisely.
Key Features
- 100mL capacity with clear 1mL graduation markings
- Polypropylene construction — lightweight, shatter-resistant, and chemical-safe
- Flat base for stable upright use on the bench
- Wide enough to accept standard hydrometers and alcometers
- Easy to clean and reuse batch after batch
- Compatible with beer, wine, cider, mead, and spirit samples
How to Use
Pour a sample of your beer, wine, or spirit into the cylinder until it's approximately three-quarters full. Gently lower your hydrometer or alcometer into the liquid and allow it to float freely without touching the sides. Read the measurement at the liquid's surface level and record your result.
Who Is This For?
This is an essential piece of kit for anyone measuring gravity (specific gravity) during brewing or checking ABV (alcohol by volume) in finished spirits and wines. If you own a hydrometer or alcometer and don't already have a trial jar, this is the missing piece.
Good to Know
Polypropylene is alcohol-safe and won't degrade with repeated exposure to spirits, sanitisers, or cleaning agents. It's a more practical choice than glass for everyday brew-day use — no risk of breakage on the bench.
