Description
Filter support PC for LF3 / LF5 / LF30 / LF31 is a polycarbonate filter support component designed for use with the corresponding Witeg vacuum filtration units. Positioned beneath the membrane in the filtration stack, the support provides a stable, permeable base that allows filtrate to pass freely into the collecting vessel while holding the filter medium securely in place. Manufactured from PC, the part combines dimensional stability with the mechanical strength required for repeated vacuum cycles. It is supplied as a single piece with a net weight of 0,8 kg and is intended specifically for the LF3, LF5, LF30 and LF31 filtration apparatus series. In laboratory vacuum filtration the filter support is a critical interface between membrane and receiver, ensuring even flow distribution and reliable sealing within the assembly. Offered by manufacturer Witeg, this PC support is suited to analytical and preparative filtration workflows that employ the listed LF models. Its dedicated compatibility simplifies replacement and maintenance of Witt-type and related vacuum filtration systems in research and quality-control laboratories.

Questions about Support base PC for LF3 / LF5 / LF30 / LF31
What is this article?
Support base PC for LF3 / LF5 / LF30 / LF31 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Conductivity meters & cells, inside pH & electrochemistry, in Lab instruments.
A conductivity meter and its cell measure how well a solution carries current. The cell constant is the geometry that converts conductance to conductivity, and it is calibrated with a standard. Temperature compensation matters because conductivity rises with temperature.
A pH meter is a voltmeter on a glass electrode. The voltage tracks hydrogen-ion activity, and the electrode is converted to pH only after it is adjusted with buffers of known value. Conductivity measures how well a solution carries a current, which for dilute salts tracks concentration. Dissolved oxygen and titration are further electrodes on the same idea: a sensor, a standard, and a reading that is only as fresh as the calibration. Buffer values and chemical identity sit on PubChem. Accreditation of the calibration laboratory is the field of BELAC and EURAMET.
