so I've been using http://www.medical-and-lab-supplies.com/ to buy my flip tops, vials, oils and solvents. The rubber stoppers bleed back after pulling the dart out. my question is what other supply companies do you all like to use?

I've not tried med-lab-supplies vials yet, as they were mostly out of stock last time.

For sealed sterile vials, I bought some from http://www.gpzservices.com/

Their 20ml vials are OK. I only bought a handful for myself and they came paired in bubble wrap. There were some very slight scratches on the outside of the glass, but overall they look and work good.

Did you filter into your vials with an 18g needle by chance? I did this, and after warming up my vial on a heating pad before drawing, some of the oil was bleeding through the stopper. (I did have it laying on its side though). I think it's because the 18g needles tear such a big hole in them which allows it to seep out when warm?

Next time I do a run, I plan on using 20g needles to filter instead of 18g to try and prevent this. Also with the 18g needles, a piece of my rubber stopper actually broke off into the vial after I filtered, which sucked because I had to insert another needle to try and draw it out of the oil. Eventually I'll get setup with a Millipore system.
