500ml Borosilicate Reagent Bottles

These Reagent Bottles are made from the same laboratory borosilicate as our Erlenmeyer Flasks. No silicone o-ring required. These 500ml Regent Bottles are ideal for the boiling and storage of wort for your starter, or transporting yeast from yeast starters. Simply place in microwave to sterilise wort then cap and put in fridge until you need to make your starter. The whole bottle can be autoclaved. Safety warnings: **Please still exercise care when handling these and any other Borosilicate glass.** There is a common misconception that Borosilicate glass is virtually bulletproof and can handle any dramatic temperature that is thrown at it. This is not strictly true. Though it does have an incredible ability to withstand sudden and drastic temperature shocks compared to your average soda-lime glass, it should still be treated consciously with care. Cool all glassware slowly to prevent breakage, unless you are using VYCOR gla
