BD blunt 5um filter needle - update

[Sampei]

Seems like any of these filters from the spike vials to the needle filter when they encounter HIGH BB gear the filters goes bad very quick.

I tried to draw from 3 vials in one sitting and on the third vial the filter failed and kept sucking only air and no oil was coming in the syringe..had to use a new needle to end the drawing.

This shit is happening with the spike too, after few drawing the spike suck only air and oil doesn't come down. Probably the filter melt

Coincidentally, I've been scratching my head about this same issue.

I have to agree... my thoughts were the corrosive chemicals in oils (BB; BA) are causing pre-mature failure of the vial spikes.

In the photos below, this area of the Braun vial spike continues to fail and start separating.

I'm trying different drawing techniques to see if limiting the amount of oil left in the neck of the spike will help prolong it's use.

I HAVE had a couple spikes last a few weeks. Others have failed, either due to fragility, or too much oil welling-up in the neck.

Warm the oil, draw slowly. I had the same prob until I started taking my sweet ass time drawing

The Spike i don't know and I'll try but I always draw slowly, the blunt needle with filter I draw the oil super slow but failed in 1 minutes or ,at the 1.3ml mark lol

I noticed that it never failed once with my bac water vial so it's surely the solvents in the oil or something else that it's still related to the oil

I never thought to use a spike for my bac water vial... Thanks for that tip bro!

I don't have any needle filters, just the spikes.

I'll give Narta's tip a try and see how that works.

IDK if it has to do with the angle or the draw speed (the way air is filtered in), the one's that have failed tend to have more oil drips. The one's that havn't failed/lasted longer have less oil drip.

Actually, the shorter life started when I tried using one of Narta's other tips—getting more oil into the syringe vs air when drawing—pushing air from the syringe into the vial before drawing. That works very well.

So, I'm sure my draw method/technique is the issue if solvents from the oil somehow aren't supposed to reach the parts that are failing.

Mine it's 100% the solvent imho because if it's wasn't the solvent it would work for longer and it happened the same with the filter needle.... I guess I'll have to stick to 10ml vials and try to not think too much about coring xD
