70 µL M6 Flow Cell: Locating a Small Measurement Region (MQQSC051)
Custom design guide · MQQSC051
A small masked measurement region sits between two female M6 connections. This compact flow block needs the mating fitting, seal seat and beam position to be reviewed together.
The situations and proposed changes below are planning examples, not completed customer projects.

Locate the small optical region between the threaded ends
MQQSC051 combines a nominal 3 mm path and 70 µL capacity in a 33 × 12.5 × 12.5 mm quartz block. Its two opposed interfaces are female M6 openings, with masking around a small central optical region. It is a layout to consider when threaded connections and a compact observation region must share one support.
The optical position and the fitting interface are separate decisions. A fitting can match the thread designation but fail to seat or seal as required; a support can accept the block while placing the beam outside the useful region. Both need to appear on the same installation drawing.
The listed configuration

How the structure differs from a conventional cell
The sample region becomes smaller within the block, and fluid access moves to the two ends. Masking around the optical region adds an alignment constraint. The nominal 70 µL describes the cell configuration, while fittings, tubing and flushing add their own liquid demand.
Keep the seal seat and sample region in the same review
For an existing male fitting, send the drawing with the sealing surface and required engagement. Identify the 3 mm path and holder contacts that must stay fixed. We can review a connection change with the quartz remaining around the interface and the route into the sample region.
For a different optical centre, show the beam and holder datum before moving a window or opening. The sample region, masking and end connections interact. Specify the optical result or alignment requirement you need, rather than assuming that a larger visible window will deliver it.

Three checks for the proposed setup
- Male mating part. Specify the fitting, seal location and required engagement.
- Beam location. Give beam size and centre relative to the support datum.
- Operating conditions. State the medium, deposit/particle concerns and required leakage checks.
Check assembly and filling before interpreting a signal
Support the body and attached hoses, then check for continuous filling, retained bubbles and residual liquid in the observation region. Agree operating and cleaning conditions for the adhesive-bonded construction. Working pressure and optical performance require their own evidence; the configuration record does not establish them.
Can fittings from an external-M6 cell be reused here?
Check the actual mating parts. This block has female M6 openings, so a connector arrangement used with male cell ends may not suit it. Thread engagement, seal seat and sealing components must match the selected interface.
Engineering dimension reference
The reference records known external dimensions and configuration notes. Internal geometry, tolerances and operating limits still require a project-specific specification.
