| Can I filter hot liquids in my pressure vessel? | NOTE: This technique is not recommended for any potentially combustible solvents. Care should be taken before proceeding. In addition to being autoclavable, the pressure vessel can also be heated before and during filtrations. We have heated the unit to as high as 90C while in use. We have filtered liquids with the entire pressure vessel and filtration apparatus in an oven, have put the vessel into hot water baths, and have used a hot plate. The hot plate did not provide good heat distribution and the rubber bottom burned slightly under the direct heat contact, but this method could still be used in a pinch. In our experience we found that heating in the oven was the best choice with the water bath a close second. Of course, before doing this it is important that you check 1) the compatibility of your liquid with the o-rings and stainless steel under elevated temperatures, and 2) the flammability/volatility of your liquid being filtered. This technique is not recommended for any potentially combustible solvents. One example of a potentially combustible solvent is Isopropanol. |
