High quality borosilicate glass

When you’re looking for a replacement beaker, you should choose one that is we made with quality borosilicate glass. Although all glass, no matter how well made, is breakable, it is a good idea to purchase one that you can trust. The GROSCHE replacement beakers are made of borosilicate glass. This type of glass can resist very high temperatures and will also never cloud.

Beaker sizing

This is an area that often confuses buyers of French presses. A “3 cup” beaker or a coffee press, actually has a capacity of 350 ml, or 11.8 oz. Its not 3 North American sized cups of coffee, but 3 cups per a European measure of a “cup” size, which are close to 3.4 oz. each. Likewise, an 8 cup replacement beaker is actually a 1 liter or 34 fl. oz capacity, or around 2-3 North American coffee mugs. Please be sure to check the exact size of your coffee press before ordering the beaker. This is a very common error so its advisable to check and be sure before moving ahead with this.

How to replace the glass beaker in your French press

When replacing glass beakers please use caution to ensure that the glass doesn’t break. Although borosilicate glass is fairly strong for its weight, excess pressure could shatter and potentially injure someone. Try light pressure to move the beaker and wear gloves to protect your hands. Some cafetieres release the beakers easily, while others require some level of disassembly.
