Question about Filters

[silv10]

Hello , i just bought 0.22um 13mm, nylon filters , and this filters are tiny AF , how much TEST CYP ml can be filtered trough this filters , cus i got 100ml and i just have 10 filters of these, thank you!

It even says "Not for medical, Lab Use only"

hopefully they have the word "sterile" in the product description and come individually sealed.

My experience in brewing with a 13mm 0.22um PVDF filter it's 1 hour for filtering 30ml and 11 minutes for filtering 30ml with a 32mm 0.22um PVDF filter.
Oil used is GSO with Test E 300mg/ml 2%BA and 12%BB
With MCT oil it's thiner so it could be faster.

By the way a 13mm can filter just 10ml !!!
A 32mm can filter 100ml !

Was the oil warm?

yep, they are sterile and individually sealed

@alphastrength50 yes it was warm at 40°C because my filter works until 45°C
And according to me, if you warm a lot, Benzil Alcool could evaporate... well i guess...

it takes a lot to boil away benzyl alcohol. Even though it will begin to evaporate before it boils, it’s boiling point is 401F

a 25 mm .22 um I got 100 mL easy. It took 20 min for all 100 mL. Slightly warm with MCT and a 3 cc syringe.

 

[alphastrength50]

Would a 10cc syringe fit nicely into a caulk gun?

No. You want 60cc syringes and fill to roughly 40 to 45 ml.

Thank you for that response cuz I want to laugh every time I see someone say that. Nothing against the person that said it but from experience you know it's not true. Otherwise stuff would be growing all inside of things like Tren base.lmfao...

Would boiling it too hot ruin the plastic syringe?

If you get the oil too hot the syringe will start melting. You shouldn't need to boil your oil or your syringe.

This is the answer as well as for the filter limits. Do not melt plastic in your gear. Do not melt your plastic filter in your gear while filtering.

Sorry not boil I meant around 150degrees lololol

The heat resistance on different material membranes is different. What is the actual membrane made from? Probably nylon witch is hydrophilic or PVDF witch comes in both hydrophobic and hydrophilic? Hydrophobic being much better. However if its PVDF hydrophobic then it needs to be pre wet with a solvent like BA first...

I don't take temps. I warm the product in a beaker to the point where i can still comfortably hold the beaker and the product is very warm.
