what is the pore size of the material. To be effective I need something with less than 6-7 microns

Mr. Boddy, I suggest going to Allersolf's website for this highly technical question. With this exception, I am very pleased with the Allersolf pillow cases and mattress cover that I purchased because 1) they are excellent in their capacity as pillow protectors and a mattress cover because they are high quality, and because their very tight 100% cotton weave is very smooth, absorbent, cool, and very comfortable, and 2) I don't know if they help with my allergies but they definitely don't make my allergies worse.

I'm sorry but I don't know the pore size. It's not listed in the description nor on the case. I don't have the pkg it came in anymore either. Sorry I couldn't help more but I have been very happy with these.

I would use a smaller concentration then50%. It's kinda strong, I actually caused some scaring on my skin the first time used it removing a mole.

None that I know about. The only thing I know to do is use non-toxic Mylar or even aluminum foil as a reflector. Of course diamond Mylar is better. (Not that great, I know.) Leave space for cooling.

j. ; hi do not have one of the clear glass files in front of me, but they are pretty small. I am thinking only 1 mL. if you would like me to, in about six days I will be able to get back with you with an extract size.

5 micron is the largest size, you can use a 1 micron if you wish. If you use anything larger then 5 micron the "bugs" can hide behind the particles! I use a 5 micron filter.

Hello there. To answer your question, no the mean particle size is NOT less than 100 nm. I searched for a few days to find a product that had a particle size of LARGER than 100nm. If you scroll down, under "product description" it states: "Produced from naturally occurring zinc ore, super purity (free from other metals). Cosmetic grade particle size 200-1000 nanometer (nm) or 0. 2-1 micrometer)."

It depends on the volume that you want to cover. My experience with it is that the does not shrink much after curing and the minimum thickness I would suggest is about 0.1" I found that it was hard to feather edges. I only used it to fill and repair mortar and bricks that were chipped.

I don't know if you can use that filter however I would say it is very important to use the SuperSterasyl Filters to achieve the 5 micron's (99.99999% pure)

the cavity is 7" x 1.25" so if your shorter than 7" there will be an air void between you and the end of the cavity - using a sharp scissors you can easily cut the material a little shorter to reduce or eliminate the air void

3M 16000 PPS Standard Size Kit with 200 Micron Filters There are three sizes I am not sure what size you need but the 16000 is the mid size

I have been researching small filter as I work with various manufacturers of larger reverse osmosis systems. Frankly, this product scares me; you need at least 0.1 micron to filter out bacteria. That still leaves viruses, some chemicals, silica, and various dissolved solids. The only way to deal with some of these other contaminants is to use reverse osmosis.

Around 1.75 inches, give or take a few thousandths. I don't have a micrometer to be exact.

The factory filter bag is rated for 2 micron nominal. I am not aware of any alternate filter bags as the assembly may not be capable at proper dust/chip removal if you try to go less. The restriction at 1 micron or less may be a problem. Keeping the filter bag clean is easy enough - just tap on the sides when finished. I find the unit does a very adequate job considering the price. If finer filtration is required I would suggest an air cleaner set up with HEPA filtration.

A micrometer, commonly known as micron is one millionth of a meter, one thousandth of a millimeter or one thousand nanometers. A strand ofhuman hair is about 100 microns wide and a red blood cell is approx. 8 microns in diameter. A Micron is .000039 inch or .001 mm. This filter is rated at .003 Microns! Get this filter!!

It is not ideal to make ferrofluid with this product since the particle size is close to 30 microns. We do sell a synthetic iron oxide that has a much smaller particle size of less that 1 micron that would work better.

I would say that the .005 would be the minimum thickness if it were secured well on all sides, it still might have a wavy look. The .020 thickness would be the best choice for that application in my opinion.

I checked with a ruler and to be safe I'd say 7mm, but it could be slightly less than that.
