Usage Guidelines for Quartz Glass Evaporating Dish
Proper Handling & Preparation
- Initial cleaning: Before first use, clean with dilute (2-5%) HCl or HNO₃, followed by thorough rinsing with deionized water.
- Handling: Always handle with clean gloves or tongs to prevent contamination and fingerprints.
- Inspection: Visually inspect for chips or cracks before each use, especially after thermal cycling.
Isıtma Yönergeleri
- Heating rate: For optimal thermal shock resistance, heat at a rate of 5-10°C/minute when exceeding 500°C.
- Support: Place on ceramic fiber or silica supports rather than direct contact with metal heating elements.
- Heat distribution: Ensure even heating across the dish base to prevent thermal stress points.
Temizlik ve Bakım
- Regular cleaning: Use dilute acids (except HF) or lab-grade detergents. Avoid abrasive cleaners that may scratch the surface.
- Removing stubborn residues: Soak in 5-10% nitric acid solution overnight, then rinse thoroughly with deionized water.
- Storage: Store in clean, dust-free cabinets. Consider individual storage containers to prevent contact with other labware.
- Avoid: Hydrofluoric acid (HF), which will etch and dissolve quartz glass. Also avoid rapid cooling from temperatures above 1000°C.
To extend the lifespan of your quartz evaporating dishes, avoid direct flame contact and never place hot dishes on cold surfaces. Proper care can result in years of reliable laboratory service.

SSS
Q: What is the maximum temperature a quartz glass evaporating dish can withstand?
A: TOQUARTZ® quartz glass evaporating dishes can withstand temperatures up to 1450°C in continuous operation. The softening point of the material is approximately 1730°C, but we recommend staying below 1450°C for prolonged use to maintain dimensional stability and material integrity.
Q: Are quartz glass evaporating dishes resistant to all acids?
A: Quartz glass evaporating dishes are resistant to most acids, including strong mineral acids like sulfuric, nitric, and hydrochloric acid. However, they are not resistant to hydrofluoric acid (HF) or concentrated phosphoric acid at elevated temperatures, which can etch and dissolve the quartz material.
Q: What is the difference between round and flat bottom quartz evaporating dishes?
A: Round bottom dishes provide more uniform heating and are preferred for crystallization processes where even temperature distribution is critical. Flat bottom dishes offer greater stability on heating plates and are easier to place on analytical balances for precise weighing. The choice depends on your specific application requirements.
Q: How can I clean residue from a quartz glass evaporating dish?
A: For routine cleaning, use laboratory detergents followed by thorough rinsing with deionized water. For stubborn residues, soak in a 5-10% nitric acid solution overnight. For inorganic residues that won’t dissolve in acid, you can heat the empty dish to 1000°C to burn off organic contaminants. Never use abrasive cleaners that can scratch the surface.
Q: Can TOQUARTZ® quartz evaporating dishes be used for microwave-assisted digestion?
A: No, quartz is not microwave-absorbing; our dishes are not suitable for microwave digestion systems.
