Filters and pre-filters.

Im looking to purchase some pre-filters but cant locate anywhere that sells them.Also....ive been reading about .1 and .5 filters lately ...anyone know where these can be bought??

Cheers guys.

i have a crapload of .20 um filters sterile nylon membrane and these work great for homebrews, solvent capable will sell cheap PM me.

they are great, ask flex he uses them too.
what are ya filtering? the membrane type is important, and the capacity, and pressure capable, smaller filters in UM are less likely to keep some hormone in the solution, the smaller you go the more filters u use and more hormone is decreased and trapped in the filter

You can go here to get Prefilter 1.0 µm: http://researchlabsupply.com/Scripts/prodList.asp?idCategory=28

I hate to sound like a dumbass, but please forgive me.

1: Are these filters reuseable?
2: Is that $5 a piece for the filters @ http://researchlabsupply.com ?

Please excuse the dumb questions, but it's of importance to me before I purchase.

Thanks

Hi those prices are for each item. When you click the "View" button it will open a page with more details and you will see the price is for 1 item.

Just like syringe filters (http://researchlabsupply.com/Scripts/prodView.asp?idproduct=31) the vacuum filtration system (http://researchlabsupply.com/Scripts/prodView.asp?idproduct=177) and the Glass Fiber Prefilter 1.0 µm (http://researchlabsupply.com/Scripts/prodView.asp?idproduct=131) are all made for single use. But when you are filtering large amounts like those filters are made for the price is not to bad.
