Glass Hydrometer Test Tube Jar & Cylinder Brush - Narrow Flask for Alcohol by Volume Test - Moonshine, Homebrew Beer, Home Wine Making Kits, Borosilicate Glass 3.3 Description Features: Brewers Love Glass Test Jars! Glass is more hygienic and easier to see through. High proof distillers need to use glass and not plastic to avoid chemical compound breakdown with their strong alcohol levels. No pH changes and contaminants potentially leached from soda lime glass. Solid: 1-piece Thick borosilicate Boro 3.3 glass jar with a bumper guard. No Leaks! It is STURDY and STABLE, laboratory grade: low expansion rate, high temperature resistance, high intensity, high transmittance and high chemical stability. Easy to Read: Graduated cylinders have lines that block the ability to read. Ours is clear and completely transparent plus tall enough to get the best readings, but narrow to waste less brew! Sturdy Box and Environmentally Responsible: Packaged to Minimize breakage. Both the box and glass jar are made from recycled materials. Stay organized for storage and it is great for gifting and easy to wrap as a gift. We personally inspect each piece and include our microfiber cloth for added protection. Also we include our direction sheet and conversion chart.
