Combination Cartridge & Paper Holders

The following filter holders may be used for the collection of solid particulate on paper and/or volatile compounds in a filter cartridge taken from the air with either a high or low volume pump. In choosing the correct holder one needs to know the specific paper size (usually 2" or 47mm dia.), and a cartridge configuration. Cartridge configurations can be found under the Analytical Cartridge Section of this catalog. All HI-Q filter holders are machined from 6061-T6 Aluminum (unless otherwise specified) and anodized Black, Gold or Blue depending upon the filter media they accept. Add a "-SS" to unit model number for Stainless Steel holder construction.
