DougoeFre5h said:it can be, depends on heat and concentration. For the most part...the filter will be slower than even a 23 or 25g needle.
Mr. dB said:...and if you're using sterilized, pre-sealed vials, small needles will chew up the rubber stopper less.
pullinbig said:use vials with no stopper and then you dont need a needle at all. after you filter it in put a red fold over stopper on the vial. if you insist on hand filtering this is by far the easiest way. 10ml syringe and warm solution filtering is a breeze.
i posted directions for presterilizing vials which are not sterile. i used 150 ml vials. then baked in them and then transferred to sterile presealed smaller vials.
No no, hes referring to those stoppers with sleeve's i believe, no crimper necessary.Mr. dB said:That's all fine and good if you're doing enough quantity to make the purchase of a crimper economically feasable. For the rest of us, a $150 crimper would be a significant expenditure, relative to the rest of the materials for a batch of goodies.
