Glass material

Abstract

The invention provides a glass material, which comprises the following components in percentage by weight: 40 to 70 percent of SiO2, 1 to 15 percent of B2O3, 0.5 to 8 percent of Al2O3, 5% to 20% of ZnO, 6 to 16 percent of Na2O, and 1 to 18 percent of MnO2, V2O3, Fe2O3, CuO, CeO2, NiO, Co2O3 and Cr2O3. Through reasonable component design, the glass material obtained by the invention has relatively low transmittance in a range from visible light to near-infrared band, has excellent chemical stability and relatively low high-temperature viscosity, and is suitable for production of platinum vessels.

Description

technical field [0001] The invention relates to a glass material, in particular to a high-uniformity glass material with relatively low transmittance in the range from visible light to near-infrared band. Background technique [0002] Molecular diagnosis has the advantages of short detection time, high sensitivity, and strong specificity. In recent years, it has become an important development direction in the field of precision medicine and personalized treatment. Polymerase chain reaction technology (PCR) is a key technology in the field of molecular diagnosis. Its technical core lies in the precise quantitative analysis of the fluorescence generated during the reaction process. For example, in the microfluidic gene detection chip, the fluorescence signal generated by the microunit The more accurate the extraction, the higher the detection accuracy of PCR. [0003] The accuracy of fluorescent signal detection depends on a highly uniform black background. If the coating te...

Problems solved by technology

In addition, the black background material is also required to have excellent acid and water resistance, especially in recent years with the development of array chips for biological detection. If the material has poor acid and water resistance, the substances in the material will be corroded and precipitated by the culture solution. , especially the precipitation of alkali metal ions and transition metal ions will interfere with the fluorescence of active substances, thereby reducing the accuracy of fluorescence detection

[0004] In the prior art, refractory materials are usually used as melting vessels for black glass. If the high-temperature viscosity is too high, it is basically impossible to obtain a high-quality product and a high-uniform black background; at the same time, the transmittance in certain wavelength bands is high, which cannot meet All black background requirement
