2. ~~Cleanout ports~~ 20190129: no longer relevant; mounting a glass cuvette inside pressure cell

## Notes

1.	ISS offers a 3-window cell that is overspecified for pressure but otherwise appropriate for this application. It accommodates a round or square cuvette sealed with a Teflon plug.

2. Quartz windows for that cell are available separately, $160/ea (see quote for cell). They are 19 mm diameter, 8.5 mm thick; designed to provide a 10 mm aperture (see email from Beniamino Barbieri @ ISS.

3. [Here is a work-in-progress scale sketch](https://cad.onshape.com/documents/469bf1d505c7c4ef4e77fe10/w/c7b2f301d190eae42597c511/e/58fca7b84d4f4066138ca32d) of the (non-pressurizable) cuvette holder presently mounted in the RF-1501.
