(MQQFL020) Quartz Flow Cell, 10 mm path, 5.8 mL nominal capacity, Long Sample Chamber
Description
MQQFL020 is a JGS1 quartz flow cell with a 10 mm optical path and 5.8 mL nominal capacity. Its long sample chamber, one-tube-plus-open-end layout and 79 × 12.5 × 12.5 mm uncapped envelope make it suitable where you want direct access to the sample region as well as a fixed tube connection on one side.

Choose this option
Choose this cell when your method benefits from a larger nominal volume than a compact flow cell and the open-end access suits how you fill, drain or inspect the sample region. The single fixed tube provides one defined connection point, while the opposite open end leaves the chamber accessible for handling that would be awkward in a fully closed two-port body.
What makes this option different
- 5.8 mL nominal capacity with a 10 mm optical path in a long sample chamber.
- One fixed tube and one open end for a different loading and connection layout from closed two-port cells.
- Fixed tube size of 4 mm OD / 2 mm ID for planning external connection hardware.
- Molded 83 JGS1 quartz construction with Two-Way Light geometry for UV/Vis use.
Structure and dimensions

Using this cell
Support the cell body during handling and installation, and do not use the fixed tube as a handle. Because this version has one open end, fill and drain it in a way that keeps the optical region covered and free of trapped bubbles before taking a blank or sample reading.
The 5.8 mL figure is the nominal capacity, not a stated minimum working volume. If your method runs close to the lowest practical fill level, check that your actual fill in the intended mounting position keeps the beam path covered consistently.
First-use check
- Inspect the optical faces, the open end and the fixed tube connection for particles or handling residue.
- Test the fit in your holder and run a blank with the cell in its intended measuring position.
- Fill slowly and verify that the illuminated region is fully wetted and free of bubbles.
Fit and optical alignment
View the English selection reference.
The fixed-parts envelope is 79 × 12.5 × 12.5 mm, excluding separately attached flexible tubing and removable caps. Check holder length, side clearance and access to the open end separately from the optical body fit.
Z Height is not established for this SKU, so do not assume beam-center compatibility from the overall dimensions alone. If your instrument or holder requires a defined beam height, that point should be checked before ordering.

Solvents and cleaning
Molded 83 is commonly chosen for methods involving organic solvents and temperature-related applications, but suitability still depends on the complete assembly and the actual liquid conditions. The source also describes this construction as acid- and alkali-resistant in general terms, but specific chemical limits are not established here.
Do not use hydrofluoric acid with quartz. Avoid hot strong alkalis and abrasive cleaning materials, and clean the optical faces gently with non-abrasive optical tissue. For aggressive chemicals, elevated temperature or long contact times, please review the full liquid conditions before use.
