First of all, bottle top filtering is terrific. I love not using those awful whatmans.
I bought the Nalgene MF75
One of the big issues surrounding bottletop filtering is transferring the finished product into a vial quickly, effectively, with minimum air exposure.
I bought 60 ml catheter tip syringe without needle
I thought the catheter tip would enable me to retrieve the finished product into a syring very quickly. I was wrong.
The 60 ml size syringe was too thick to manuever inside the bottom end of the filter unit. I couldn’t reach the corners and thus a lot of the product. I need a syringe that can quickly, effectively retrieve the product so I can transfer to vial.
The next size down is 20 ml, which should have plenty of manuevering capability, but worries me because I don’t want to make 2-3 trips to retrieve the product.
My needles wouldn’t fit on the 60 ml syringe. They won’t fit the catheter, although I think they will fit the 60 ml luer lock or luer slip, but I’m not positive. These needles are from my 3 ml injection syringes.
I want to change how I retrieve the product from the filtration unit and transfer to vial. Any ideas?
Either way I don’t want to waste another brew!
