Hi everyone, Just to let you guys know due to the work on the roof from the 24th-28th the stills won't be operational for that week. A new run literally just finished an hour ago, so there are 2 bottles of nitric upstairs (just brought a new one downstairs), and 2 bottles of HCL. I won't be able to run the stills until the 3rd of March, and that will take another 4 days to complete the run. Please take that into consideration for your upcoming procedures, the new HCL bottle I brought down yesterday afternoon is nearly empty so make sure the 2 bottles upstairs will be enough for your work 🙂 This isn't related to the AHU but some of you might have noticed I changed the labels on the bottles to be colour-coded. Single distilled is now green, double distilled is yellow, and HF remains red. This is to avoid confusion if in the future double distillation is done upstairs 🙂 Thanks everyone! Have a good one 🙂 Cheers, Sofiya Sofiya Valkova (hi/ei) Technegydd Ymchwil Ysgol Gwyddorau'r Ddaear a’r Amgylchedd Prifysgol Caerdydd Prif Adeilad, Plas-y-Parc Caerdydd CF10 3AT Ffôn : +44 (0)29 2087 76647 Ebost: valkovas(a)caerdydd.ac.uk Mae'r brifysgol yn croesawu gohebiaeth yn Gymraeg neu yn Saesneg.
