| 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. |

Applications
Dispensing pressure vessels hold liquid for filtration through Millipore pressure-operated filter holders, if connected to an external pressure source. Vessels meet ASME®-UM Code requirements. Closures are secured by cam-lock handle. Vessels are autoclavable when vented. Accessory code-complying relief valve, pressure gauge and hose connectors are available. Accessory closure adapts vessels for vacuum use.

Items a - e are supplied with the vessel. Items f - k are available as accessories.
Note: Merck recommends installing the vent/relief valve accessory (item f below, Merck cat. no. XX67 00L 24) prior to use in order to comply with Pressure Directive safety requirements.
