Hi, and welcome to the forum!!

We have been completely swamped with new users with questions, so we're a little slow getting some answers to folks. In addition, in order to give you the best answers possible, some of these posts are left until the most qualified folks log into the forum to answer. For example, I can help with most all chemistry questions, but equipment is not my forte, so I would ordinarily not waste your time with a response saying so. However, it doesn't mean your post hasn't been read. So...I have deleted your other, duplicate post, and want to ask you, just as a matter of housekeeping on what is already a crazy busy forum, not to post duplicate posts with the same information and answer.

There are folks here who can give you good answers to your questions, but you might have to be a little bit patient until they answer. Don't give up!
