Side Illuminated Photoelectrochemical Cell with Quartz Window and Hermetic Gas Purge System

Product Overview

This advanced side-illuminated photoelectrochemical cell represents a major design evolution for professional laboratories conducting high-precision electrochemistry, photocatalysis, and optoelectronic research. Engineered to deliver exceptional hermetic performance, this unit integrates a high-efficiency optical window and multi-valve atmospheric control, allowing researchers to create highly controlled test environments. Whether deployed in solar fuels development or routine physical chemistry investigations, this system provides unmatched experimental stability and repeatability.

Designed specifically to overcome the limitations of standard electrochemical cells, the equipment integrates a specialized side-illumination port that aligns directly with the internal working electrode. This configuration is widely adopted across chemical, materials science, and clean energy sectors where precise photo-excitation of electrochemically active surfaces is critical. The design ensures minimal light scattering and maximum optical throughput for highly sensitive measurements.

Constructed from premium borosilicate glass and precision-machined fluoropolymers, this unit offers robust chemical resistance and thermal tolerance under demanding laboratory conditions. Researchers can confidently execute experiments involving highly corrosive electrolytes, vacuum degassing, or mild pressurization, knowing that the structural integrity and seal quality of the system will not degrade over time.

Key Features

• Precision Quartz Optical Window: The cell features an optical-grade quartz window with a light transmittance rate exceeding 95% across the ultraviolet and visible spectrums. This ensures that the incident light beam reaches the working electrode with negligible attenuation, maximizing quantum efficiency and the accuracy of photoelectrochemical yield measurements. Additionally, the window is mounted on a secure, convenient mechanical lock-ring system, facilitating rapid, tool-free replacement or thorough cleaning between experiments.
• Absolute Hermetic Sealing Architecture: Designed as an absolutely sealed system, this equipment utilizes a state-of-the-art dual-seal mechanism to completely isolate the internal reaction chamber from the surrounding atmosphere. The glass neck of the cell incorporates a heavy-duty external thread, while the internal core is fabricated from a 360-degree rotating polytetrafluoroethylene (PTFE) component. The system is securely locked using a durable polyoxymethylene (POM) outer cap, providing an airtight barrier that is critical for oxygen-sensitive or moisture-sensitive reactions.
• Integrated Atmosphere Protection and Gas Purge: Featuring a sophisticated gas-management assembly, the unit includes high-vacuum valves and a specialized sub-liquid aeration/bubbling device. The valve connected directly to the aerator serves as the primary gas inlet, enabling controlled bubbling of inert gases (such as argon or nitrogen) or active gaseous reactants directly into the electrolyte. This design ensures rapid gas saturation and efficient purging of dissolved oxygen prior to or during electrochemical analysis.
• Vacuum and Controlled Pressure Operations: The robust glass-to-polymer sealing interface allows the entire cell assembly to easily withstand vacuum evacuation down to less than -0.1 MPa, facilitating complete degassing of the electrolyte solution. Furthermore, the cell can support minor positive pressure environments up to a maximum safety limit of 0.5 MPa. This dual-capability enables researchers to explore pressure-dependent reaction dynamics and ensure total atmospheric exclusion.
• Innovative Pin-Plug Electrode Connectors: To maintain absolute hermetic integrity while ensuring reliable electrical connectivity, the cell lid is equipped with specialized earphone-style internal pin-plug connectors. The working, counter, and reference electrodes plug directly into these integrated ports within the sealed environment, eliminating the need for bulky compression fittings or unreliable feedthroughs that could compromise the atmospheric seal.
• 360-Degree Rotating Electrode Alignment: The high-purity PTFE inner core features a fully adjustable 360-degree rotational mechanism. This engineering feature allows the user to rotate the entire electrode assembly from the top without opening the cell, ensuring that the active surface of the customized working electrode is perfectly and precisely aligned with the quartz optical window. This eliminates geometric misalignments that frequently cause inconsistencies in photoelectrochemical measurements.
• Double-Jacketed Thermal Regulation Option: The system is available in both single-layer and double-jacketed configurations to suit different experimental requirements. The double-jacketed variant features an outer glass envelope designed for continuous circulation of constant-temperature water from an external bath. This configuration maintains a highly stable thermal profile within the cell, neutralizing any localized heating generated by high-intensity light sources or exothermic electrochemical reactions.
• Modular Customization and Sampling Ports: Built to support diverse experimental protocols, the cell body can be customized with an integrated sampling port for the extraction of liquid or gaseous products during long-term runs. This modularity extends to custom volume options, ranging from 30 mL to 500 mL, and the capability to accommodate highly tailored working, counter, and reference electrodes designed specifically to match the internal dimensions of the cell.

Why Choose This Product

• Uncompromised Hermetic Integrity: Unlike standard electrochemical cells, this system features a dual-barrier sealing mechanism with a rotating PTFE inner core and high-rigidity POM collar. This guarantees absolute physical isolation of the reaction chamber, which is crucial for sensitive catalytic experiments where minor atmospheric contamination can compromise long-term data validity.
• Optimized Optical and Geometric Precision: Featuring a custom mechanical lock-ring quartz window (>95% transmittance) coupled with a 360-degree rotating electrode holder, the system allows researchers to align the working electrode perfectly to the light path. This eliminates variations in incident light intensity, delivering highly reproducible photocatalytic measurements.
• Rigorous Safety and Thermal Boundaries: The technical boundaries of this equipment are carefully specified, offering distinct pressure tolerances for the single-layer and double-jacketed variants. The dual-layer model provides unmatched temperature control via an integrated circulating jacket, protecting temperature-sensitive kinetics from laser-induced thermal fluctuations.
• Tailored CNC Customization Capabilities: Leveraging our comprehensive, end-to-end CNC machining capabilities for fluoropolymers, we can customize cell volumes, design custom lids, integrate multi-port sampling systems, and build bespoke electrodes that perfectly match the mechanical envelope of the system.
