We have to have some urgent repairs conducted to one of the extractions systems which has developed a leak. As such estates will need access to the roof tomorrow morning to investigate. This means there will be NO ACCESS to the labs or any of the instrument rooms tomorrow AM between 0830-12.30. I am sorry for the short notice but Luke has worked very hard to put this in place at such short notice. We can discuss any knock on effects at the lab meeting at 11am. Please make sure all beakers are capped and nothing is left to evaporate on the hotplates. 

Cheers,

Edward
