Two Sides Clear 10mm Light Path Quartz Glass Cuvette

Brief

Cuvette is a small transparent container designed to hold liquid samples for spectroscopic analysis.

Details

It is square or rectangular with two clear opposing windows; may have fosted/grip sides to avoid fingerprints. It is used in spectrophotometers to measure absorbance, transmittance or emissions of light by samples.

Characteristics of the cuvette:

1). Strong mechanical strength, strong adaptability to temperature change, very strong bonding part, internal pressure can withstand several air pressure.

2). Extremely precise optical processing technology, excellent optical performance of the transparent surface.

3). Choose high-quality quartz glass, ensure no bubbles, no stripes.

4). Strong corrosion resistance, can withstand 6mol/L hydrochloric acid, 6mol/L hydrochloric acid, anhydrous ethanol, carbon tetrachloride and benzene for 24 hours without degluing and leakage.

Attention to use the cuvette:

1). When taking cuvettes, you can only touch the frosted glass on both sides with your fingers to avoid touching the optical surface. At the same time, pay attention to handle gently to prevent the external force from contrasting the cuvette and causing damage after stress.

2). Any solution containing substances that corrode glass should not be stored in a cuvette for a long time.

3). Do not place cuvettes on a flame or electric stove for heating or baking in a drying box.

4). When the inside of the cuvette is found to be contaminated, it should be cleaned without water and wiped clean in time.

5). Do not contact the light-transmitting surface of the cuvette with hard or dirty objects. When the solution is contained, the height is only 2/3 of the cuvette. If there is residual liquid on the optical surface, it can be gently adsorbed with filter paper, and then wiped with lens paper or silk.

Usage of the Cuvette:

1). Research and educational institutions (demanding basic and continuous supplies)

Universities and research institutes: Laboratories in departments such as chemistry, biology, medicine, environment, materials, and food. This is one of the largest customer groups, with diverse demands ranging from basic teaching to cutting-edge research.

  Demand characteristics: Wide variety (quartz, glass, micro-volume), high quality requirements (optical performance, precision), and also a large demand for low-cost routine consumables. Purchasing is influenced by research projects and budgets.

High schools, middle schools, and vocational schools: Used for basic chemistry and biology teaching experiments.

Demand characteristics: Pursue economic durability, mainly low-end glass or disposable plastic cuvettes, centralized purchasing, and sensitive to price.

 2). Testing and Certification Service Institutions (High Demand and Standardized)

Third-party Testing Laboratories: Environmental Monitoring Stations, Food Testing Institutions, Pharmaceutical Inspection Institutes, Product Quality Supervision and Inspection Institutes, etc.

Demand Characteristics: Large purchase volume, frequent use, and strict adherence to national standards (GB) or industry standards. They pursue accuracy and repeatability of data, and have extremely high requirements for the matching of colorimetric cells, optical path accuracy, and material purity. They are core customers for high-end quartz and high-quality glass colorimetric cells.

Enterprise Quality Inspection Departments: Present in all manufacturing enterprises that require process control or finished product inspection.

 3). Medical and Diagnostic Industry (High Demand and Rapid Growth)

Hospital Laboratory Departments, Pathology Departments, Central Laboratories: Used for blood analysis, biochemical indicators (such as blood glucose, blood lipids, enzyme activity) testing, etc.

Demand Characteristics: Typically serve as core accessories/consumables for fully automatic or semi-automatic biochemical analyzers. They must be perfectly matched with the instruments, with high precision, no residue, and easy to stack and feed automatically. Most are customized or brand-specific, with strong customer stickiness.

In Vitro Diagnostic (IVD) Reagent and Instrument Manufacturers: When producing reagent kits and developing instruments, they need to purchase a large number of cuvettes for testing and calibration. Some also package cuvettes as part of their instrument consumables for sale.

 4). Industrial Production Enterprises (Demand Closely Linked to Process)

Pharmaceutical and Biotechnology Companies: Used throughout the process from R&D to quality control (QC). It is applied in drug content determination, purity analysis, monitoring of cell culture density (OD600), etc.

Demand Characteristics: Special requirements for sterility and pyrogen-free (especially for micro-volume cuvettes used in cell culture and protein purification), and some need disposable products to prevent cross-contamination.

Food and Beverage Enterprises: Used for raw material testing, nutritional component analysis, additive monitoring, contaminant screening, etc.

Chemical and Petroleum Enterprises: Used for reaction monitoring, product component analysis, catalyst research, etc.

Environmental Engineering Companies: Used for online or offline water quality monitoring in the wastewater treatment process.

5). Instrument Manufacturers (OEM/ODM Major Clients)

Spectrophotometer, Enzyme-Linked Immunosorbent Assay (ELISA) Reader, and Biochemical Analyzer Manufacturers: Such as Agilent, Thermo Fisher, Shimadzu, PerkinElmer, Mindray, Bio-Rad, etc.
