Filtering gear, this is so easy I feel like I must be doing something wrong

[cap’nboldenone]

The other day I was syringe filtering some EQ through a nylon membrane .22um with a 10cc syringe and an 18g needle. Even after heating up the oil it was taking goddamn forever and halfway through the second vial the plunger on the syringe snapped.

I didn’t have another 10cc syringe and I had 3 more vials to go so I decided to filter it all through a 1cc syringe by just leaving the drawing needle and filter in the vials and swapping the barrel back and forth. Lo and behold, it flowed like water and only took like 3 seconds to filter 1cc compared to the 10 minutes it was taking to push 10cc through there.

Did I just discover a filtering hack or is there a reason you shouldn’t swap the syringe back and forth like that? Only drawback was that all the barrel swapping got oil on my hands.

the next best hack is using ptfe
it flows better

I’ll have to give those a try next time. The filters I was using + the 10cc made my thumbs feel like I had been deadlifting hook grip.

Were you using a vent needle on the filtered vial? If not, that could explain the resistance.

The real hack for getting through 50ml+

 

[cousinmuscles]

Physics my friend. The surface area of the 10ml plunger is much bigger than the 1ml syringe. The 1ml syringe is much thinner, thus the force you exert to move the plunger 10cm on the 1ml is much greater per square cm than 10cm on the 10ml plunger, despite equal effort.

Higher volume syringes are harder to push, just like larger diameter nails are harder to drive.

Yes I was.

Yeah I’ve pinned with 3cc needles so I’m familiar with the difference in resistance from surface area, I was just surprised that 1cc went so fast that I thought there must be a reason everyone doesn’t recommend doing it that way.

Going back an forth with a 1ml syringe for 10ml of oil is more cumbersome but I don't think there is an actual technical fault in doing it. I have filtered 30ml bottles of oil and had to go back and forth with my 10ml syringe. I just leave the needles in the vial stoppers and disconnect the syringe from one and connect to the other.

Look for some ptfe for oils like Photon suggested, but remember to use them only for oils, not water based solutions.
