Overview

Engineered for demanding high-temperature, ultra-clean, and severe chemical applications, this 50mL Fused Quartz Graduated Beaker outperforms standard borosilicate glass in extreme thermal and optical environments. Fabricated from ultra-high purity fused silica ( $SiO_2 > 99.99\%$ ), it offers exceptionally low trace-metal contamination, extreme thermal shock resistance, and complete transparency from deep UV through infrared spectra.

Key Features

Ultra-High Purity Silica ( $>99.99\%\text{ }SiO_2$ ): Prevents trace element leaching, making it ideal for semiconductor manufacturing, trace metal analysis, and high-purity inorganic synthesis.
Extreme Thermal Shock Resistance: Can withstand continuous operating temperatures up to $1050^\circ\text{C}$ ( $1200^\circ\text{C}$ short-term) and survive rapid temperature drops without cracking.
Broad Optical Transmission: Exceptional transparency across broad spectrums (UV, Visible, and Near-IR light), facilitating photochemical reactions and optical testing.
Superior Chemical Inertness: Unaffected by almost all acids (including $HCl, HNO_3, H_2SO_4$ ), aqua regia, and organic solvents (except hydrofluoric acid and concentrated hot phosphoric acid).
Clear Graduations & Spout: Includes high-temperature, permanent volumetric markings (50mL capacity) and a precision pour spout for accurate liquid handling.
