As a customized partner for global scientific research and industrial users, Luverre Quartz provides optical performance and size adaptation services that far exceed standard products, making every measurement infinitely close to the true value.

Frequently Asked Questions (FAQ): How can we address your core needs?

Q1: Why do my experimental results always have a large deviation in the ultraviolet region?

A: This is usually due to the use of a regular glass colorimetric dish. Glass has strong absorption in the ultraviolet region (<340nm), while our quartz colorimetric dish has a transmittance of>80% at 200nm, completely eliminating substrate interference and ensuring the accuracy of experiments such as RNA/DNA quantification.

Q2: The standard colorimetric dish is too large, and my precious sample is only 100 microliters. How can I measure it?

A: We provide customized services for trace/ultra trace quartz colorimetric dishes, with a minimum requirement of only 50 μ L of sample for detection. No dilution is needed, and high concentration samples can be directly measured, saving you 90% of sample costs.

Q3: What is the reason why the background signal is always high during fluorescence analysis?

A: Ordinary quartz may have impurity fluorescence. We use synthetic quartz material, which has no background fluorescence interference and extremely high signal-to-noise ratio, making it the optimal solution for fluorescence trace analysis.

Q4: Does the pipeline connection always leak or cannot withstand corrosion during flow injection analysis?

A: We provide flow colorimetric dishes with standard threaded interfaces, using an integrated melting process (without delamination risk), which can withstand 6mol/L strong acids, strong alkalis, and various organic solvents, fully compatible with your HPLC or FIA system.

Quartz glass colorimetric dish: the core carrier for precision measurement

Core application areas and product advantages

Quartz glass colorimetric dishes have become the preferred choice in many high-end analytical fields due to their wide spectral transmission characteristics

-Life Sciences: Used for DNA/RNA purity detection (260/280nm) and protein analysis (280nm). Our product has extremely high energy throughput and excellent signal-to-noise ratio in this critical ultraviolet band.

-Pharmaceutical and Chemical Engineering: Used for qualitative and quantitative analysis of drug components, chemical reaction kinetics research. Strong corrosion resistance, able to withstand long-term corrosion from organic solvents (such as ethanol, carbon tetrachloride) and acid-base solutions, ensuring data stability.

-Environmental monitoring: used for water quality testing (such as COD, ammonia nitrogen analysis) and air pollutant analysis. Optional long optical path (such as 50mm, 100mm) colorimetric dishes can be used to significantly improve the detection sensitivity of low concentration samples.

-Materials and Food: Used for optical material transmittance testing, food additive testing, etc.

Why choose us as a custom supplier?

-Pure material, military grade standard: high-quality fused silica is selected to ensure no bubbles, stripes and fluorescent background. Extremely high hardness, dozens of times more wear-resistant than ordinary glass, with a service life of over 5 years.

-Full band precise adaptation: Our quartz colorimetric dish has no characteristic absorption peaks in the full spectral range of 190-2500nm, while ordinary glass colorimetric dishes begin to absorb in the red light region and cannot be used in the ultraviolet range.

-Exquisite craftsmanship and durability: using high-temperature melting technology for bonding instead of ordinary adhesives. It can withstand strong corrosive media such as 6mol/L NaOH and HCl for more than 24 hours without delamination or leakage, and can withstand several atmospheres of pressure.

-Special customization: such as high-temperature and high-pressure tanks, micro capillary tanks, etc., can be customized upon request.

Customer Application Cases

Case 1: Difficulties in RNA purity testing for a biopharmaceutical company

-Background of demand: In the development of mRNA vaccines, customers require precise measurement of RNA concentration at 260nm. However, when using a regular colorimetric dish, the background absorption is too high, resulting in a significant deviation of the A260/A280 ratio from the true value.

-Solution: We have provided it with a UV quartz colorimetric dish and a customized version with a 2mm optical path length to accommodate its high concentration samples and avoid dilution errors.

-Final effect: The background interference is completely eliminated, the A260/A280 ratio remains stable at around 2.0, and the data reproducibility is improved to 99.5%. This scheme has been included in the QC standard operating procedures.

Case 2: Heavy metal detection in surface water of an environmental monitoring station

-Background of demand: A third-party testing institution undertakes the detection of trace elements in the national soil survey project. The sample size is extremely large and the concentration is extremely low. The absorbance of the traditional 10mm optical path colorimetric dish is less than 0.01, making it impossible to accurately quantify.

-Solution: Our engineers recommend customizing a 50mm long path quartz colorimetric dish and using an integrated melting process to prevent interference from adhesive precipitation.

-Final effect: The absorbance value increased by 5 times, successfully reducing the detection limit to 0.05mg/L, perfectly meeting the national standard requirements, and improving detection efficiency by 30%.

Case 3: Catalytic Reaction Dynamics Study at a Chemical University

-Background of the requirement: The laboratory needs to monitor the reaction process in situ in an environment with high temperature (80 ℃) and strong acid content. Ordinary bonded colorimetric dishes frequently come loose and explode.

-Solution: Customized high-temperature and high-pressure resistant quartz reaction tank, using all quartz material integrated molding technology, without any adhesive.

-Final effect: It can work stably within the range of -5 ℃ to 120 ℃ and can be used continuously for 6 months without damage.

Whether you need a micro quartz dish for deep ultraviolet analysis or a shaped flow cell compatible with imported automatic samplers, we can deliver the perfect product to you through exquisite processing technology and strict optical testing.
