Solving Critical Challenges with TOQUARTZ® Quartz Glass Beakers

High-Temperature Chemical Reactions with Quartz Beakers

Research laboratories and materials science facilities frequently conduct experiments that require heating corrosive chemicals to extreme temperatures. Standard borosilicate glassware fails at temperatures above 500°C and may contaminate sensitive samples through ion leaching or material breakdown.

Key Advantages

TOQUARTZ® solution

A materials science lab in Stuttgart, Germany, previously used aluminosilicate vessels for acid digestion at 950°C, which showed visible surface degradation after 10 cycles.
After switching to TOQUARTZ® quartz beakers, they completed 60+ thermal cycles with zero structural change and reduced sample contamination by 92%, verified via post-reaction ICP-OES analysis.

Precision Optical Material Development with Quartz Glass Beakers

Optical and semiconductor material developers require vessels with exceptional dimensional precision and contamination-free environments. Standard labware with dimensional variations compromises experimental repeatability and can introduce contaminants that affect optical quality and semiconductor performance.

Key Advantages

TOQUARTZ® solution

A Japanese photonics R&D firm required quartz vessels with <±0.2 mm tolerance for UV-curable polymer synthesis. Previous suppliers delivered inconsistent batches, causing 14% yield loss.
TOQUARTZ® provided beakers with certified ±0.15 mm tolerance, reducing batch rejection to <2% and improving optical clarity by 18% (measured via UV-Vis spectrometry).

Educational Laboratory Applications with Fused Silica Beakers

Educational institutions teaching advanced materials science and chemistry need durable labware that provides consistent results across multiple student experiments. Traditional glassware often requires frequent replacement due to thermal shock damage and chemical etching, increasing operational costs and disrupting educational continuity.

Key Advantages

TOQUARTZ® solution

A Canadian university chemistry department replaced 80 borosilicate beakers annually due to thermal shock and acid etching.
After adopting TOQUARTZ® quartz beakers, annual replacements dropped to 6 units, saving over CAD 2,400 and improving lab continuity across 3 academic terms.

FAQ

Q: Are TOQUARTZ quartz beakers resistant to hydrofluoric acid (HF)?

A: While our quartz beakers show excellent resistance to most chemicals, hydrofluoric acid (HF) is an exception. HF reacts with silica (SiO₂) to form silicon tetrafluoride and water. The rate of reaction depends on HF concentration, temperature, and exposure time. For very dilute HF solutions (< 1%) at room temperature, limited short-term exposure may be possible, but we do not recommend using quartz beakers for HF-containing solutions. For applications involving HF, we recommend using specialized containers made of fluoropolymers like PTFE or PFA.

A: Yes, quartz beakers can be used directly on laboratory hotplates, over Bunsen burners, or in direct flame applications. However, we recommend the following precautions: (1) Use a wire gauze or ceramic-centered wire gauze between the flame and beaker to distribute heat more evenly; (2) When heating on hotplates, ensure the beaker bottom is clean and the hotplate surface is flat; (3) Avoid sudden temperature changes when the beaker contains liquids; (4) For direct flame applications, introduce the beaker gradually to the heat source. While quartz has excellent thermal shock resistance, following these guidelines will maximize the service life of your beakers.

A: The volume markings on our standard quartz beakers are provided as approximate guides rather than for precise volumetric measurement. For standard beakers, volume accuracy is typically within ±5% of the indicated volume. If precise volumetric measurement is critical for your application, we recommend using calibrated volumetric glassware in conjunction with our quartz beakers, or requesting specially calibrated quartz beakers, which we can produce with volume accuracy within ±2% for specific applications. Each calibrated beaker undergoes individual verification and is supplied with a calibration certificate.

A: Quartz beakers differ from standard borosilicate glass beakers in several important ways: (1) Temperature resistance: Quartz can withstand up to 1200°C versus 500-600°C for borosilicate; (2) Chemical purity: Our quartz is 99.99% SiO₂, whereas borosilicate contains various other oxides; (3) Thermal expansion: Quartz has approximately 1/3 the thermal expansion coefficient of borosilicate, making it much more resistant to thermal shock; (4) UV and IR transmission: Quartz allows transmission of UV and IR wavelengths that would be blocked by standard glass; (5) Chemical resistance: Quartz offers superior resistance to most acids (except HF) and bases.

A: Yes, we can produce quartz beakers that match or exceed the specifications of other manufacturers. If you’re looking to replace or supplement existing laboratory equipment, we can work from dimensional samples, competitor part numbers, or technical specifications to create compatible replacements. This capability is particularly valuable for laboratories facing supply chain challenges with their current vendors or seeking cost-effective alternatives without modifying existing procedures or equipment setups. Please provide as much detail as possible about the items you wish to match, including dimensions, markings, and any special features.
