Featured Product
Capillary Flow Porometer
for Cartridge Media
PMI is proud to announce its new Capillary Flow Porometer for Cartridge Media. While similar to our other Capillary Flow Porometers, this new CapFlow has some additional safety components our other machines do not have. These safety features are due to the extremely high pressure used when testing the samples, which, if there were a failure in the sample, could lead to injury.
The first safety feature is the locking mechanism by Idec. This safety lock is software controlled, which means it can only be locked and unlocked by the computer software used in testing the sample. Another key Feature of this safety lock is the fact that it will not unlock until the pressure inside the sample chamber reaches zero.
The next new safety feature of this machine is the 3/8" thick safety glass on the door. This safety glass is thicker than our standard 1/4" glass, and can contain any failures sustained within the sample chamber.
Specifications & Features
The CFPC is rated for 500 psi maximum pressure in the sample chamber, and can test pore sizes ranging from 0.013 – 80 microns (but can be customized for higher). The machine has a Standard Liters Per Minute (SLPM) of 200, and performs the following tests:
- Bubble Point (Maximum Through Pore Diameter)
- Through Pore Size Distribution
- Mean Flow Pore Diameter
- Pressure Hold
- Gas Permeability
The sample chamber has the ability to test cartridges up to 25cm long, and can have many different sized adapters customized to suit your needs
