GROSCHE Borosilicate 3.3 Glass French Press Replacement Beaker 34 oz — Heatproof, Dishwasher-Safe

The GROSCHE Borosilicate 3.3 Glass Replacement Beaker (34 oz) is a heatproof, dishwasher-safe glass jar built to replace the inner carafe of many French press–style coffee and tea makers.

Replace a cracked or stained carafe without buying a whole new brewer. This 34-ounce beaker is molded from Borosilicate 3.3 glass, a formula known for better thermal shock resistance than ordinary soda-lime glass. Its straight-sided form and measured capacity make it suitable for mid-size presses and multi-use beverage preparation, while the clear glass keeps the color and clarity of your brew visible through the full extraction.

Will this beaker fit my French press?

Compatibility depends mainly on inner diameter and flange placement rather than brand alone. The GROSCHE 34 oz beaker follows common dimensions for medium-sized presses, but checking your existing carafe measurements avoids surprises.

• Capacity: 34 fluid ounces (about 1 liter).
• Designed for medium-sized French press models with straight-sided glass walls.
• Measure your original beaker’s height and diameter to confirm fit.

How durable is Borosilicate 3.3 glass for daily brewing?

Borosilicate 3.3 glass is formulated to withstand rapid temperature changes better than standard glass and is less prone to thermal stress cracks. It’s still glass, so avoid direct stovetop heating and sudden, extreme impacts to keep it intact.

• Heatproof: safe for hot brewing and chilled drinks within normal use.
• Handle with care to prevent chips from knocks or drops.
• Not intended for direct-flame or stovetop contact.

How do I clean and maintain the replacement beaker?

The beaker is top-rack dishwasher-safe for simple cleanup, and hand washing extends its life. Use non-metal utensils and soft sponges to avoid scratching the glass, and inspect seals when reinstalling into the press assembly.

• Dishwasher: top-rack safe for routine cleaning.
• Hand wash recommendation: soft sponge and mild detergent for longevity.
• Avoid metal tools; use silicone, plastic, or wooden implements only.

Can I use the beaker for other hot or cold drinks?

Yes — the straight-walled, clear glass design accommodates tea infusions, cold-brew, iced beverages, and other hot liquids prepared off-heat. Keep in mind recommended handling practices to prevent thermal shock and accidental breakage.

• Works for tea steeping, coffee pressing, iced blends, and simple serving.
• Not rated for oven or stovetop; pour hot liquids carefully to avoid extreme temperature shifts.
• Clear glass shows color and clarity, helpful for monitoring steep times.

Who this is for: Home brewers who want an affordable, OEM-style glass replacement to restore a favorite French press or to upgrade to a higher-clarity, heat-resistant carafe. It suits coffee and tea lovers with medium-capacity presses, people who prefer visible brewing, and anyone seeking an easy-to-clean, dishwasher-safe glass alternative. If you need a different capacity, GROSCHE also offers small and large sizes to match a wider range of presses.
