BoFilTest and BoCrossTest
BoFilTest and BoCrossTest are compact filtration apparatuses which can provide a quick, simple and reproducible analysis of the filtration data and the substance parameters, even with only small sample amounts.
BoFilTest enables fast, easy and reproducible analysis of filtration data for both vacuum and pressure filtration. Even with very small quantities of suspension, it is possible to determine the filtration parameters and material parameters which are relevant for process design, apparatus design or for compliance with regulations.
BoFilTest is very versatile. Therefore, numerous production facilities, laboratories, control institutions and research institutions worldwide use it for one of the many possible applications.
BoFilTest is characterized by the following features:
The simple handling of BoFilTest allows a quick test procedure. Due to the quick-release closures on the upper and lower part of the pressure filter cell, a test can be started immediately after filling in the sample suspension. One hand movement is enough to get BoFilTest ready for a test.
With a filtration area of only 20 cm² and a filtration pressure of up to 11 bar (a) BoFilTest allows
Optionally, the measured values can be electronically recorded and evaluated.
The core of the BoFilTest is a double-walled pressure filter cell made of stainless steel, which can be tempered by a liquid circulation if required. It is closed by a quick release lid with hinge and sight glass. The lower part is attached to the body of the pressure filter cell with a bayonet quick release. In this lower part of the filtrate outlet funnel, a perforated plate as support for the filter medium and a removable cake-forming ring are integrated. The pressure filter cell is mounted on a base frame in which a laptop holder is integrated. In the basic version, this device is supplemented by a manometer for setting and measuring the filtration pressure difference.
The basic version was deliberately designed in such a way that it can be operated on site even without power supply. The versatility and ease-of-use of the BoFilTest can be adapted at any time to suit individual requirements by means of various, mostly metrological, auxiliaries.
