Description

A Borosilicate Glass Conical Flask is an idea vessel for making yeast starters for home brew beer making. Ensuring that enough healthy yeast is pitched at the start of your brew will ensure good, quick fermentation and will allow the brew to attenuate fully. Use either liquid malt extract, dry malt extract or make it really easy and use PROPPER STARTER

Making a yeast starter is quick and easy and will take your home brewing to another level. Check out the BYO article here or our instructional video below

Recommend using only a gas stove top, not your electric stoves.

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 glassware which can go from high heat to ice water with no damage.

Do not take your boiled flask directly from the stovetop straight into a bath of ice water. Though some people do this without failure, borosilicate glass is not designed for such an application.

Please allow the flask to cool for a few minutes before running under water, before placing into an ice bath; the slower you introduce your flasks to temperature changes, the longer it will last. Going from fire to ice in a matter of seconds will introduce incredible amounts of stress to the glass structure. While the glass may be able to withstand this some of the time, other times you may not be so lucky. If the temperature differential is big enough, it will shatter.

All Borosilicate glass will break eventually after a number of heat/cool cycles, it is impossible to give an exact number to determine when, but this is a natural an inherent feature of the material.

Please do not boil your flasks dry or dry them out using a stove. The temperature for drying should not exceed 140°C, which a naked flame can easily exceed.

Do not heat glassware that is etched, cracked, chipped, nicked, or scratched. It is more prone to break.

Do not heat glassware directly on electrical heating elements. Excessive stress will be induced in the glass, and this can result in breakage.
