Quartz microporous array sheet

Quartz microporous array sheet is a special component prepared by precision microfabrication technology on ultra-high purity quartz glass substrate, with micropores arranged in a regular matrix. It perfectly combines the ultimate transparency, excellent temperature resistance, and extremely low thermal expansion coefficient of quartz, which can meet the requirements of wide spectral transmission from ultraviolet to infrared. As a core fluid control and optical substrate material at the microscale, this product is widely used in fields such as biochips, microfluidics, single-cell analysis, and high-throughput screening. It is an indispensable key consumable and core component for modern precision instruments and cutting-edge scientific research.

Frequently Asked Questions (FAQ)

Q1: What is the conventional aperture and spacing range of quartz microporous array?

A: We provide micro hole processing with extremely high aspect ratios. The conventional aperture can reach 5 μ m to 500 μ m, and the minimum pore spacing can reach 10 μ m (depending on the aperture size and substrate thickness). Support customization of various hole types such as circular holes, square holes, hexagonal holes, etc.

Q2: How high temperatures and harsh chemical environments can the product withstand?

A: Using semiconductor grade high-purity quartz glass, with a softening point exceeding 1100 ℃, it can work stably at high temperatures of 1000 ℃ for a long time without thermal deformation. Resistant to most acid-base corrosion except hydrofluoric acid and high-temperature phosphoric acid, suitable for extremely harsh experimental and industrial environments.

Q3: Does it support customization of non-standard sizes and special thicknesses?

A: Fully supported. From a few millimeters of microchips to 300mm (12 inches) large wafer level array chips, with thicknesses ranging from 0.5mm to 10mm or more, we accept customized drawings or samples and provide one-stop services from design consultation to processing.

Core needs and pain points to be addressed

For researchers and equipment manufacturers, quartz microporous array sheets fundamentally solve the three major pain points of deformation of ordinary glass or polymer consumables under high temperature and pressure, weak signal caused by low UV transmittance, and poor biocompatibility leading to sample adsorption or cross contamination. It not only ensures the absolute uniformity of fluid distribution in microfluidic experiments, but also greatly improves the sensitivity and reliability of optical detection data.

Core advantages and application value

Ultimate optical performance: extremely high transmittance in deep ultraviolet (<200nm), no background fluorescence, providing the purest optical substrate for fluorescence quantitative PCR and single-molecule imaging.

Ultra high precision and uniformity: Using advanced photolithography and precision etching processes, the aperture tolerance is controlled within ± 2 μ m to ensure that the fluid dynamics characteristics of each micropore in the array are completely consistent, ensuring the parallelism of high-throughput screening results.

Unparalleled surface properties: The surface is extremely smooth, supporting hydrophilic/hydrophobic and biomolecule (such as antibodies, proteins) surface modification, effectively reducing non-specific adsorption.

Full scenario specification customization capability: Breaking the limitations of standard products, whether you are pursuing single-cell capture with extremely small aperture or particle enrichment with large aperture, we can accurately match the size of your device cavity.

Application Case Analysis

Background: A top European life science instrument company (anonymous) encountered a bottleneck in developing a new generation of "high-throughput single-cell multi omics analysis system". The original polymer microplate undergoes slight deformation during the PCR amplification heating stage, resulting in the failure of microporous sealing and sample evaporation; And it produces strong background fluorescence under ultraviolet excitation light, which seriously interferes with weak signal detection.

Solution: We are deeply involved in the customer's early-stage research and development, and customized quartz microporous array sheets with a thickness of 2mm, a pore size of 30 μ m, and a pore spacing of 50 μ m based on their optical and flow channel designs. We have carried out special smooth polishing treatment on the microporous sidewalls and reserved high-precision alignment marks at the edges of the sheet.

Final result: The customer's equipment achieved 100% zero leakage in thermal cycles above 100 ℃, and the single-cell capture rate was increased to over 95%. Due to the absence of fluorescent background in quartz, its detection signal-to-noise ratio has increased by three times compared to the old scheme. After mass production, the stability of its consumables has been widely recognized by top research institutes worldwide.
