(MQQLW005) Quartz Flow Cell, 17.5 mL nominal capacity, Large Optical Window with Side Tube
Description
MQQLW005 is a JGS1 quartz flow cell for UV/Vis spectroscopy with a 10 mm optical path and 17.5 mL nominal capacity. Its open-top body gives direct access to the sample region, while the single tube on the closed bottom face provides one fixed connection point for your liquid path. This format is useful when you want top access for filling, rinsing or visual checks without giving up a defined tube connection below.

Choose this option
Choose MQQLW005 when your setup benefits from an open sample chamber rather than a closed cap format. The combination of a larger 17.5 mL nominal volume, straight two-way optical path and one bottom tube suits UV/Vis arrangements where sample handling from above and tubing space below both matter during installation.
What makes this option different
- 10 mm optical path in a Two-Way Light layout for straightforward UV/Vis transmission measurement.
- Open Top with Bottom Tube combines direct access from above with one projecting tube on the bottom face.
- 17.5 mL nominal capacity offers a larger chamber than compact low-volume flow cells.
- OD 5 mm / ID 3 mm tube helps you plan the connection side of the assembly.
Structure and dimensions

Using this cell
Support the cell by the quartz body during handling and installation. Do not lift or position it by the projecting tube alone. When filling or rinsing from the open top, add liquid slowly so the optical region wets evenly and visible bubbles can clear before measurement.
If the cell is used as part of a connected liquid path, set the operating direction and plumbing arrangement for the complete assembly. The single bottom tube identifies the connection location, but pressure limits are not specified for this item.
First-use check
- Inspect the optical faces, chamber and tube area for chips, residue or handling marks.
- Place the cell in the holder and verify that the beam passes through the intended optical faces.
- Fill, remove visible bubbles and exterior droplets, then run a blank before sample measurement.
Fit and optical alignment
View the English selection reference. Also available in the product gallery.
The body measures 52.5 × 12.5 × 45 mm. Check these dimensions against your holder or mounting space, then leave extra room for the bottom tube and any attached tubing below the cell.
Z Height is not listed for this model, so beam-center fit should be checked from your holder geometry or dimensional reference rather than assumed from the outer body size alone.
View the English dimensional reference. The reference is also available in the product gallery; series photographs may show other options.

Solvents and cleaning
Rinse promptly after use and clean the optical faces gently with non-abrasive optical tissue or another non-scratching method suitable for quartz. Choose the cleaning liquid for the full wetted setup, not the quartz body alone.
Keep hydrofluoric acid away from quartz. Avoid hot strong alkalis and abrasive cleaners. If your method involves aggressive chemicals, long contact time or elevated temperature, check suitability for the complete assembly before use.
Included with this option
1 Quartz Flow Cell. The listed price is for one piece.
