Hello! First post here, so hopefully I'm not doing anything wrong. I've hit a dead end with an experiment and could use some additional perspective. I'm in need of material for a 100 mL round boiling flask that has good transparency down to about 140 -180 nm. I originally considered Type 214 Fused Quartz, but I need a material that will not fluoresce. Pyrex won't fluoresce, but it's only transparent down to about 340 nm. I also cannot afford to purchase the material in bulk, meaning it will likely have to be a material someone has in stock and not made to order. Essentially, I need a material... Transparent down to ~140 nm Non-fluorescing Small quantity Any ideas for a material (and/or supplier)? Thank you in advance.
