Usage Guide for Quartz Petri Dish
Cleaning & Preparation
Initial Soaking
New quartz petri dishes should be soaked in clean water to dissolve any surface contaminants. For new dishes, rinse with tap water and soak overnight in 5% hydrochloric acid solution.
Thorough Scrubbing
After soaking, scrub dishes with a soft-bristled brush and laboratory detergent. Avoid abrasive materials that could damage the polished surface. Rinse thoroughly after scrubbing.
Acid Soaking
For thorough cleaning, soak in cleaning solution or acid bath for at least 6 hours (preferably overnight). This oxidative process removes all organic residues and contaminants.
Thorough Rinsing
After acid treatment, rinse dishes at least 15 times with fresh water, followed by 2-3 final rinses with distilled or deionized water. Proper rinsing is critical for cell culture applications.
Cleaning & Preparation
- Always handle with clean gloves or tools to prevent contamination and fingerprints.
- When heating, apply temperature changes gradually when possible, though quartz can withstand thermal shock better than standard glass.
- Store in clean, dust-free environment, preferably wrapped in lint-free paper or in dedicated storage containers.
- Avoid direct contact with hydrofluoric acid (HF), which is one of the few substances that can etch and damage quartz.
- For sterilization, quartz petri dishes can be autoclaved, dry heat sterilized, or flame sterilized without damage.

FAQ
Q: What is the difference between the JGS-1, JGS-2, and JGS-3 quartz glass grades?
A: JGS-1 is far UV grade quartz with high OH content (2000 PPM), offering excellent transmission down to 185nm. JGS-2 is UV grade with moderate OH content (100-200 PPM), suitable for 220-2500μm applications. JGS-3 is IR grade with minimal OH content, optimized for 260-3500μm wavelength transmission. The choice depends on your specific wavelength requirements.
Q: How do I clean quartz glass plates without damaging them?
A: For optical applications, use isopropyl alcohol or acetone with lint-free wipes. For general cleaning, a mild detergent solution followed by thorough rinsing with deionized water is recommended. Avoid abrasive cleaners and tools that could scratch the surface. For stubborn contaminants, ultrasonic cleaning in appropriate solutions is effective.
Q: Are your quartz glass plates suitable for semiconductor applications?
A: While our quartz glass plates meet many requirements for semiconductor-adjacent applications, we do not currently serve the high-end semiconductor industry that requires ultra-high purity (99.9999%) and specialized certifications. Our products are suitable for research, optical, laboratory, and industrial applications with purity levels up to 99.995%.
Q: Can you drill holes or create custom shapes in quartz glass plates?
A: Yes, we offer precision drilling, cutting, and machining services for quartz glass plates. We can create custom shapes, holes, slots, and other features according to your technical drawings. Our capabilities include water jet cutting, ultrasonic drilling, and precision grinding to achieve complex geometries while maintaining material integrity.
Q: How do quartz glass plates compare to borosilicate glass?
A: Quartz glass offers significantly higher temperature resistance (1100°C vs 500°C for borosilicate), superior UV transmission, better chemical resistance, and lower thermal expansion. Borosilicate is more cost-effective for applications that don’t require these advanced properties. For high-temperature, optical, or chemically demanding applications, quartz glass is the superior choice.
