UV-filtering quartz tubes are specially treated quartz glass tubes designed to selectively block specific ultraviolet (UV) wavelengths while maintaining high transparency in the visible and infrared ranges. Their key characteristics include: 1. UV Blocking Performance Cut-off Wavelength: Filtering Efficiency: 2. Optical Properties Transmittance: Refractive Index: 1.458 (@589 nm), same as standard quartz glass. 3. Material and […]

Quartz tubes and halogen tubes differ significantly in terms of heat resistance, main composition, and application range, as detailed below: 1. Heat Resistance 2. Main Composition 3. Application Range Conclusion In summary, quartz tubes are ideal for industrial applications requiring high heat resistance and broad utility, while halogen tubes are favored for their ease of

The difference between heating wire and quartz tube is quite simple: heating wire is just a heating wire, while quartz tube heating consists of a heating wire + quartz tube. Naturally, the price of quartz tube heaters is higher. In terms of performance, the differences are as follows: GlobalQT is a leading manufacturer of quartz

Cleaning of Glassware 1. Shaking Water Wash Basic explanation of the shaking water wash method. 2. Brushing for Stubborn Stains If there are substances on the inner

The application of high-transparency quartz tubes is expanding, with their increased transparency reflecting significant performance advantages across various fields. Here are the specific benefits of high-transparency quartz tubes in practical applications: 1. Enhanced Light Transmission Efficiency High-transparency quartz tubes mean minimal light loss during transmission, which is crucial for applications requiring high light transmission efficiency,

Quartz tubes start softening when exposed to temperatures above 1265°C. For safety and optimal performance, it’s recommended not to exceed a furnace temperature of 1210°C for more than three hours. The temperature resistance of quartz tubes is directly related to their purity—the higher the purity, the better the heat resistance. Key Recommendations for Using Quartz
