Kodak #5 Optical Flow Cell / Filter Holder 27 MIN Lab Aperture Fixture 3x3

Kodak #5 Precision Optical Flow Cell / Filter Holder Assembly – Marked “27 MIN” – Machined Lab Aperture Fixture

✅ Overview

Offered here is a Kodak-marked precision optical/lab assembly, clearly labeled “Kodak #5” and “27 MIN”. This is a machined metal clamping fixture with a chemical-resistant polymer insert and compression-style tube fittings, designed for controlled spacing and stable alignment in scientific setups.

These aren’t consumer camera parts — this is the kind of specialized Kodak lab hardware used in scientific imaging, optical measurement rigs, flow/sample handling, photometric systems, and industrial instrumentation.

✅ Rare Kodak-marked component

✅ Proper lab-grade build (machined + clamped + stable)

✅ Perfect for optics / flow-cell / measurement setups

🧠 What It Is

This appears to be a Kodak Optical Flow Cell / Optical Filter Cell / Aperture Fixture, intended to hold or interface with:

optical filters / window components

in-line sample paths (gas/fluid)

photometric / scientific imaging optics

measurement beam paths or optical monitoring systems

The “27 MIN” marking indicates a minimum spacing / minimum setting reference point — typical of precision fixtures where spacing matters.

📏 MEASUREMENTS

Measurements are approximate (shown in photos):

Overall footprint: approx 3" x 3"

Overall height: approx 2"

Center aperture / opening: approx 1.5"–1.75" diameter

Tube fittings: compression-style fittings (Swagelok style / lab tubing)

✅ Please reference the photos with measuring tape for full detail.

✅ Condition

Pre-owned / surplus lab component — in good condition.

Light surface scuffs/scratches from normal handling/storage

No cracks observed in the insert

Threads/hardware appear intact and complete

No major dents or bending

⚠️ Specialty technical item: no calibration/flow testing performed.

You will receive the exact item shown.
