Hope your feeling better hun. Get well soon
As for me-courier driver offering to carry my package into my house, eve though it is very heavy and came not in a packet or box but a big wooden crate that was nailed together and fixed up with steel brackets round each edge and big metal tabs that needed a screwdriver and pliers to get the thing open and for me to get my brand new rotavap out. And as well, accidentally wrote off the over £70 in taxes I 'owed' to the government and their ever-greedy coffers, leaving me a very generous amount of money towards the new vacuum pump, manifold, cryo-trap and vacuum gauges for both direct measurement of pump output and also a separate vacuum gauge to be set up between every port on the manifold and the vacuum regulator stopcocks I'll be using to regulate the vacuum, so I can thus have it set up so I can connect up multiple separate systems and have them each maintained at different negative pressure gradients, according to my needs; or to perform tasks such as doing more than one vacuum distillation at once, using the manifold run a cow each ( a 'cow' as used in vacuum distillations is a piece of glassware which accommodates several receiver flasks and the part that does so can be rotated around like the cylinder of a revolver, ad the flask that is receiving distillate swapped instantly in order to switch the fraction currently being cut, all without interrupting the distillation or taking down and rearranging vacuum parts, cleaning grease off things and regreasing parts etc., all a lot of effort whilst the parts are still damn hot, distillate is still trickling drops out of the condenser etc. So taking a flask off to attach another in order to collect another fraction cut at a different temperature means the entire thing is removed from being under vacuum, which in many cases would be disastrous, such as air-reactive compounds or those that react dangerously with water. The 'cow' allows a chemist using it to preattach the flasks and just rotate them round whilst the system is still maintained under vacuum and no other interference is necessary to change flasks over and collect multiple different cuts during a fractional distillation done under vacuum.
