The minimum pressure of the Maxfil is 0 psi. The Maxfil is rated to meet the pressure requirements of the TCLP method.

what is the maximum viscosity, maximum temperature and maximum pressure that the MaxFil can handle. Question from a Dutch lab. Thank you.

The Maxfil meets the TCLP requirements of SW-846 Method 1311. Maximum pressure and viscosity depend on what type of filter you are using. The maximum temperature for the Maxfil is about 300 C.

Can your ZHE1000 be used to do the initial filtering of samples proir to the ZHE leachate or do | have to have the seperate PF000-2 filtration system as well?

The ZHE+ is designed to perform all the steps prior to tumbling necessary for volatile analysis according to method 1311 for TCLP. The initial removal of liquid must be done in the ZHE device. Similarly, the Maxfil is designed to perform all steps necessary prior to tumbling for the analysis of non-volatile components for TCLP. It has different specifications from the ZHE and therefore should not be utilized for samples for volatile analysis.

What is the weight of this unit?

The shipping weight is 13.5 lbs.

Regarding the maxifil: what is the type of fitting for the pressure? How is the bottom: is there a simple hose beneath, under which one leaves an open bottle to collect the filtered solution? Thanks

The pressurization port has a 1/4 inch (0.635 cm) quick connect fitting. The female end is attached to the unit and the male end can be connected to your pressure source. The bottom of the unit has an exhaust port with a standard hose barb fitting. One can leave a container directly underneath to collect the filtered solution or attach a hose to direct the solution to a more convenient location.
