(MQQSC003) Quartz Screw-Top Cuvette, 3 mm path, Large Screw Opening
Description
MQQSC003 is a quartz screw-top cuvette for UV/Vis measurements that use a 3 mm optical path and need optical access on four sides. The screw-cap format gives direct top access for filling and closure, while the Four-Way Light layout supports measurement setups that use more than one optical direction around the cell body. This option has a 1050 µL nominal capacity and is supplied as one piece with an accompanying closure.

Choose this option
Choose MQQSC003 when your method uses a 3 mm path and your setup benefits from optical access beyond a basic two-window arrangement. The Four-Way Light layout is the main distinction of this version, and the screw-top format keeps sample loading straightforward when you want to fill from above and close the cell before measurement.
What makes this option different
- 3 mm optical path for methods specified for a short path length.
- Four-Way Light configuration for optical access on four sides of the cell body.
- Screw-cap format for direct top filling and removable closure handling.
- 1050 µL nominal capacity to help plan sample preparation and rinse volume.
- One-piece sale unit supplied with an accompanying closure.
Structure and dimensions

Using this cell
Fill the sample through the top opening and fit the supplied closure as needed for your handling routine. Keep the intended optical faces clean, and use a consistent orientation for blank and sample measurements when your method depends on a defined beam direction.
The 1050 µL value is a nominal capacity. It is not a minimum working volume, so low-fill methods should be checked against the illuminated region in your own setup.
First-use check
- Inspect the optical faces, chamber and closure seating area before first use.
- Place the cell in the holder and confirm the beam passes through the intended optical direction.
- After filling, remove bubbles and exterior droplets before running the blank and sample.
Fit and optical alignment
View the English selection reference. Also available in the product gallery.
Allow clearance above the holder for the neck and for removing or refitting the screw cap. If your instrument has a fixed beam center or a tightly defined holder, please review holder fit carefully before ordering because external dimensions and Z Height are not established for this SKU.
The screw-cap format identifies the closure style for loading and handling. It should not be treated as a pressure-rated connection.

Solvents and cleaning
Molded 83 is used for this cuvette configuration. This fabrication style is commonly chosen for methods that may involve organic solvents, but suitability depends on the complete cell assembly, including the closure.
If your method involves aggressive chemicals, elevated temperature or long contact time, please check the exact conditions for the assembled cell before use. Keep hydrofluoric acid away from quartz. Avoid hot strong alkalis and abrasive cleaners, and clean optical faces gently with non-abrasive laboratory wipes suitable for optical surfaces.
Included with this option
1 Quartz Screw-Top Cuvette and an accompanying closure. The listed price is for one piece.
Availability and ordering
Order this specification directly, or contact us to check current availability and dispatch timing. If temporarily unavailable, additional preparation or production time may be needed. For a required delivery date, contact us before checkout; preparation or production is separate from carrier transit and customs clearance.
Discuss a custom version
We coordinate custom JGS1 quartz production for projects involving path length, optical access, opening style, nominal capacity, fabrication and dimensional requirements. If you need a holder-specific fit, send a drawing or labelled sketch with the beam position, critical dimensions and closure requirements so the geometry can be reviewed for your application.
Send a product-selection enquiry with SKU MQQSC003, your instrument or holder details, sample conditions, required quantity and delivery destination.
