Wide-Neck Quartz Cell: Planning Electrode Access (MQQFC066)
Custom design guide · MQQFC066
MQQFC066 is a wide-neck quartz cell with a nominal 16 mm path and 4.5 mL capacity. Its threaded opening provides access above the sample chamber. When an electrode is part of the proposed setup, the cap opening, support and light path need to be planned together.
The situations and proposed changes below are planning examples, not completed customer projects.

Plan access above the sample
For a proposed measurement with an immersed electrode, access above the sample matters as much as the optical path. The shaft has to pass through the opening, the tip has to reach the intended liquid level and the cable needs a route out of the compartment. A wide-neck cell brings those requirements into one design discussion.
Start with an electrode drawing showing its tip and required immersion, then add the holder and beam. A proposed trial would check insertion and removal as well as the working position: a tip that fits the neck may still approach the window or cell floor. These are planning steps; the current cell is not presented as a validated electrochemical system.

Give each 16 mm dimension its own label
The nominal optical path and the source neck internal diameter are both 16 mm. One describes light travelling through the sample; the other describes access through the neck. Label them separately when discussing insertion or changing the opening.
The optical body is 20 × 20 × 20 mm. Overall height is 36 mm without the cap and 42 mm with it. Cap-hole dimensions and material still need confirmation for the intended electrode and medium; a photograph alone cannot define the seal or mating fit.
Keep the intended optical directions clear
The source describes five transmission faces. Choose the illumination and collection directions your method actually uses, then check them with the electrode and holder in place. Extra transmitting faces do not by themselves establish low background, signal strength or instrument compatibility.

Design the cap around the electrode
To retain the 16 mm path and body, send the electrode model or dimensioned outline with the desired immersed position. Mark the cap opening, shaft support, cable direction and removal space.
Distinguish a cap opening that simply provides access from an assembly that must seal around the shaft. For sealing or venting, provide the medium, temperature, orientation and acceptance requirement. Those details allow the cap, electrode support and wetted materials to be assessed and quoted as one project.
Checks to agree before ordering
- Insertion: Check shaft, tip and support clearance throughout insertion and removal.
- Optics: Check the chosen beam directions with the electrode and holder present.
- Cap assembly: Agree hole, wetted materials and any requested sealing check with us.
Sample and cleaning conditions
Agree sample and cleaning conditions for the complete item, including wetted caps, seals and fittings. Give chemical identity, concentration, temperature and contact time. Avoid hydrofluoric acid; strong alkalis, heat and prolonged exposure also need review. A JGS1 material label alone does not establish suitable operating conditions.
