Choosing between filtration systems
Hi Guys,
I am trying to decide between either disposable filter (Whatman Zapcap) or a glass filtration system such as the link below. My issue is how is the glass filtration system sterilised? Also does anyone know of an Australian supplier of the Whatman zapcap?
Any pros cons between the two also.

If you don't brew very offer I suggest you use disposable filter, easy and convenient to use, just throw it away after you use. If you brew very often, you can use the glass one. Only thing is that you need to sterilize it every time you use, it's troublesome but more economic.
You also need a pump.

Thank you.
My question is if i choose to go with glass, how do you sterilize?

How much is that vacuum pump? Mine takes a lil while but I always filter everything 3 times.

Good question I clean with vinegar then boil glassware the bake in oven to 350 for 1hr. But without a secure environment or lab equipment kinda hard to believe to get 100% sterile. I even alcohol flush glassware prior to use and bake to 350 for 10 minutes. I am sure there is a much simpler way. Would love ❤ to hear it that would cut my process time down for sure. But over time I have amassed a lit of glass filtration set ups just to make things go smooth.

As far as I know you can put it in alcohol for some time to sterilize, the alcohol will volatilize. Or you can put it in a oven with high temperature. Or you can use both.

I personally I wouldn't go with that big of receiver bottle. It's such a skinny top it's a pain in the ass to get it clean nevermind to get it to dry during sterilization even in the oven at 350 degrees. Regardless of what kind of receiver bought let is the best way to sterilize it is, wash it out with hot water and 90% isopropyl alcohol. When you're done washing it spray again with 90% isopropyl in the inside that way it dries faster put it in the oven at 350 degrees for 30 min. Not only does isopropyl alcohol help clean and sterilize your bottle but it will make it dry faster while in the oven. Unless you're running a major operation you could get away with the 250 ml receiver bottle 500ml at the most. Best tip I can give you out of all of those are not to use a filtration system that has a metal filter holder, but one that has a silicone stopper that you slide a filter funnel inside of.

Thanks bigmills.
Any particular reason you advise not to use a metal holder? Also any idea where i could get one with a silicon stopper?

Take a receiver if 250-500ml if you volumes are not big. Sterilization of the glass media bottle is not that difficult.
- Rinse it with antibacterial soap
- Rinse it very well with IPA, and put them upside down to dry for about 20min
- Cover the necks with foil, in a way that nothing can go in
- Turn the oven and warm to 350-400F
- Put your stuff in the oven for 30-40min
- When the time is done, turn off the oven and open the over door a bit, but not completely.
- Let it cool down by itself
- Done
- i always do this for my media receiver and all the vials. Also i was doing this with my old glass media system
Good luck
