Overcoming Critical Challenges in Laboratory Applications with TOQUARTZ® Quartz Erlenmeyer Flasks
Quartz Erlenmeyer Flasks in Photochemical Reaction Studies
Key Advantages
-
UV Transmission Efficiency
Transmits over 85% of UV light at 254 nm, enabling efficient photochemical activation. -
Reaction Visibility
Allows direct observation of colorimetric changes during UV exposure without distortion. -
Non-fluorescent Material
Quartz does not fluoresce under UV, ensuring no interference with optical sensors.
TOQUARTZ® solution
A Canadian university photochemistry lab reported inconsistent results using borosilicate flasks due to poor UV transmission (<50% at 254 nm). After switching to TOQUARTZ Quartz Erlenmeyer Flasks, UV penetration improved by 70%, enabling reproducible photocatalytic degradation of dyes. The lab reduced experiment failure rates by 40% and shortened reaction times by 25%.
Fused Quartz Erlenmeyer Flasks in Trace Metal-Free Sample Preparation
Key Advantages
-
Ultra-low Metal Background
Leaching of Fe, Al, and Na < 0.01 ppm after 24h acid soak (per internal TOQUARTZ test). -
Acid Cleaning Compatibility
Compatible with repeated soaking in 10% HNO₃ or HCl without degradation. -
Inert Surface Chemistry
No catalytic interaction with trace analytes during digestion or dilution.
TOQUARTZ® solution
A Polish environmental testing lab faced 12% sample rejection due to elevated background metals from PTFE and glassware. After adopting TOQUARTZ Quartz Erlenmeyer Flasks, blank contamination dropped below detection limits (<0.005 ppm), improving pass rates to 98% and reducing rework costs by over €3,000 per quarter.
Quartz Glass Erlenmeyer Flasks in Controlled Atmosphere Reactions
Key Advantages
-
Inert Gas Compatibility
Maintains structural integrity under vacuum or inert gas purge up to 1 atm differential. -
Joint Precision
Ground joint tolerance ±0.1 mm ensures leak-free sealing with standard stoppers. -
Thermal Cycling Stability
Withstands repeated heating/cooling cycles from -80°C to 300°C without cracking.
TOQUARTZ® solution
A Japanese organometallic synthesis group reported frequent joint leaks and flask failures using standard glassware in glovebox setups. After switching to TOQUARTZ Quartz Erlenmeyer Flasks, leak rates dropped to <1%, and flask replacement frequency decreased by 60%. This improved experiment reproducibility and reduced downtime by 18 hours/month.

FAQ
Q: What is a Quartz Erlenmeyer Flask?
A: A Quartz Erlenmeyer Flask is a conical laboratory vessel made from high-purity quartz glass (99.99% SiO₂). It features a narrow neck and wide base, designed for mixing, heating, and storing solutions in high-temperature or chemically aggressive environments.
Q: Is a Quartz Erlenmeyer Flask used for filtration?
A: While Quartz Erlenmeyer Flasks can be used as collection vessels during filtration processes, they are not primarily designed for filtration. For direct filtration applications, specialized quartz filtration apparatus with fritted discs or membrane supports are recommended.
Q: What is the typical purity level of TOQUARTZ Quartz Erlenmeyer Flasks?
A: TOQUARTZ Quartz Erlenmeyer Flasks are manufactured from 99.99% pure SiO₂, making them suitable for high-purity applications where metal contamination must be minimized.
Q: What are the safety precautions for Quartz Erlenmeyer Flask?
A: Key safety precautions include: inspecting for damage before use, using appropriate handling tools and PPE, avoiding rapid temperature changes, never heating sealed flasks, and using proper supports during experiments to prevent tipping or falling.
Q: How to clean a Quartz Erlenmeyer Flask?
A: Clean Quartz Erlenmeyer Flasks by rinsing with distilled water immediately after use. For residues, use dilute acids (1-5% HCl or HNO₃) or appropriate solvents followed by thorough rinsing with deionized water. Avoid abrasive cleaning tools that may scratch the surface.
