In the field of precise biomedical experiments, the selection of each tool and material is crucial, which is directly related to the accuracy and repeatability of experimental data and the safety of personnel. Among many materials, JGS2 quartz glass (also called synthetic quartz glass) has become an ideal choice for high-end experimental devices and utensils due to its unique physical and chemical properties.

What is JGS2 quartz glass?

JGS2 quartz glass is a synthetic quartz glass highly recommended for its excellent optical and physical properties. It exhibits excellent performance in the visible and near-infrared spectral ranges, and has low dispersion characteristics, which can effectively reduce color difference and improve the imaging quality of optical systems.

As a special industrial technology glass, JGS2 quartz glass is made of silicon dioxide and has excellent properties such as high temperature resistance (softening point of about 1730 ℃, can be used for a long time at 1100 ℃) and corrosion resistance. It is suitable for high-precision optical instruments, semiconductor manufacturing, optical communication, and scientific research fields. In addition, it is often used to manufacture optical components such as prisms and lenses, as well as optical systems that require high stability in harsh environments, such as space technology, detection and tracking systems, and spectroscopic instruments. It is also used as a window material for high-temperature operations.

Detailed explanation of core advantages

The advantage of JGS2 quartz glass is not a single existence, but a comprehensive reflection of its internal characteristics, providing a comprehensive guarantee for biomedical experiments.

1. Extreme optical transmittance: a window illuminating the micro world

Advantage description: JGS2 quartz glass has very high transmittance in the ultraviolet and visible near-infrared spectral ranges (the ultraviolet range can reach more than 85%). This means that the optical signal has very low loss and high fidelity when passing through it.

Problems solved:

Difficulties in UV application: many biomedical experiments rely on UV light, such as UV sterilization, UV detection of DNA/protein (such as UV spectrophotometer), fluorescence microscope excitation, etc. Ordinary glass will strongly absorb ultraviolet light, so that effective operation cannot be carried out. JGS2 quartz glass perfectly solves this problem.

Improve detection sensitivity: In fluorescence detection, chemiluminescence and other weak light signal experiments, high transmittance ensures that the signal strength is not weakened, thus improving the detection signal noise ratio and sensitivity, making the experimental results more accurate and reliable.

Typical applications: UV germicidal lamp casing, fluorescent cuvette, PCR reaction tube, cover plate of high-throughput screening plate, glass slide and cover slide of optical microscope (for UV fluorescence observation).

2. Excellent thermal stability: cope with severe temperature changes

Advantage description: JGS2 quartz glass has a very low coefficient of thermal expansion (about 5.5 × 10 ⁻⁷⁷⁷⁷/℃), which means that it is very insensitive to temperature changes and can withstand severe temperature changes without cracking.

Problems solved:

Eliminate the risk of thermal stress cracking: during the experiment, such as PCR (polymerase chain reaction), it needs to go through 94 ℃ → 55 ℃ → 72 ℃, and ordinary glassware is very easy to crack due to thermal expansion and cold contraction. JGS2 quartz glass can easily cope with this harsh thermal cycle to ensure the safety of the experiment.

Support high temperature and high pressure sterilization: all biomedical experimental vessels are required to be sterile. JGS2 quartz glassware can be repeatedly autoclaved (121 ℃, 1 atm) or even dry heat sterilized (above 200 ℃) without deformation or performance degradation, and has a very long service life.

Typical applications: PCR tube/plate, observation window of cell culture reactor, high-temperature reaction container, observation window of sterilizer.

3. Excellent chemical inertia: guard the purity of samples

Advantage description: JGS2 quartz glass has excellent chemical stability. Except hydrofluoric acid and hot phosphoric acid, it hardly reacts with other acids, bases and organic solvents. Its surface is very dense and is not easy to be polluted or absorb samples.

Problems solved:

Prevention of sample pollution and adsorption: When storing or processing precious biological samples (such as proteins, nucleic acids, cell extracts), metal ions on the vessel wall will dissolve or adsorb on the surface, which will lead to sample loss, denaturation or pollution, resulting in wrong results. The high purity of JGS2 quartz glass ensures the integrity and authenticity of samples.

Resistance to harsh cleaning process: laboratory utensils need to be cleaned frequently with strong acid (such as aqua regia) and strong oxidant (such as chromic acid lotion). JGS2 quartz glass can resist the corrosion of these corrosive cleaning agents to ensure that it is thoroughly cleaned and not damaged.

Typical applications: standard solution storage ampoule bottle, chromatographic flow cell, micro sample storage tube, long-term biological sample library.

4. Extremely high mechanical strength and purity: solid and clean

Advantage description: Although its density is lower than that of ordinary glass, quartz glass has higher mechanical strength and better scratch resistance. Its synthesis process determines that it almost contains no impurities, bubbles and internal stress.

Problems solved:

Reduce interference factors in the experiment: Impurity ions (such as Na+, K+, Ca ⊃2;+) in ordinary glass may dissolve during the experiment, interfering with cell culture or biochemical reaction sensitive to ion concentration. JGS2 quartz glass provides an absolutely "clean" environment.

Enhanced durability: higher strength means that vessels are less likely to break during daily use, cleaning or high-speed centrifugation, reducing experimental costs and safety risks.

Typical applications: centrifuge tubes, precision optical element substrates, long-life experimental vessels.

Examples of typical application scenarios

Quartz cuvette of ultraviolet visible spectrophotometer: this is the most classic application. No matter nucleic acid concentration measurement, protein quantification (280nm) or enzyme kinetics research, it is inseparable from the full wave band (including ultraviolet) accurate transmittance guarantee provided by JGS2 quartz cuvette.

The core optical components of the fluorescence detection system: glass slides of high-end fluorescent microscopes and special petri dishes of confocal microscopes, which require absolute low fluorescence background and high light transmittance.

Microfluidic chip substrate: In Lab-on-a-Chip, JGS2 quartz glass is used to make chips. Its chemical inertia protects the sensitive biological samples flowing in the channel, and its optical performance facilitates the transmission of external detection light.

Special light source shell: the shell of ultraviolet germicidal lamp, xenon lamp and other light sources needs to efficiently export light of specific wavelength.

JGS2 quartz glass is not an ordinary material, but a "performance responsibility" born to meet the demanding needs of high-end biomedical experiments. Through its extremely high optical transmittance, excellent thermal stability, excellent chemical inertia and incomparable purity, it has systematically solved a series of core problems in the experiment, such as signal fidelity, temperature tolerance, sample purity and tool durability.

Although its cost is higher than that of ordinary glass, it is undoubtedly a wise and critical choice to invest in JGS2 quartz glass vessels and devices to ensure the success of scientific research for top-level research that pursues accurate data, reliable experiments and repeatable results. It is a reliable partner and clear window for scientists to explore the mysteries of life and promote medical progress.
