# chamberchip_f584 — reference-chip bundle (chamber-chip family)

**ADAPTATION** of a microfluidic ChipShop single-reaction-chamber chip, re-built as a
monolithic resin-SLA block: one 20 µL / 500 µm stadium reaction chamber, two straight
0.5 mm feed channels, and two vertical top access bores. Vendor part = COC body + foil lid.

## Provenance / honesty
- **Vendor (product page):** 20 µL chamber, 500 µm depth, 2 ports.
- **OURS (not the vendor's):** footprint (27.86 × 7.0 × 2.3 mm), stadium aspect,
  wall/floor/ceiling, straight feed channels, straight cylindrical ports. Vendor TDS robots-blocked.

## Verification (trimesh, merged vertices)
| metric | value |
|---|---|
| chamber volume (mesh) | 19.9955 µL (−0.022 % vs 20 µL analytic) |
| chamber depth | 500 µm |
| chip watertight / Euler | True / 0 (genus-1: one cavity, 2 vents) |
| footprint | 27.86 × 7.00 × 2.30 mm |
| px_min (500 µm feature) | 26.32 px X / 20.83 px Y |

## Print note
Tilt ~30–45° about the short axis, one port draining / one venting; flush IPA port-to-port
BEFORE any UV post-cure. Ports = straight bores; standing in for the vendor's MFCS Mini Luer sockets.

## STATUS
**DESIGN-VERIFIED** — watertight + volumetrically checked in CAD.
