Microlab 600 Series
Chemical Compatibility

The MICROLAB 600's fluid path consists of PTFE-based materials (PTFE and CTFE) and borosilicate glass. These materials are resistant to a wide variety of acids and bases at room-to-moderate temperatures. Most chemicals do not affect PTFE at normal operating temperatures

Important: Do not use the MICROLAB 600 for prolonged periods at high temperatures with aromatic or highly halogenated compounds. These compounds may cause the MICROLAB 's fittings to swell, adversely affecting performance and reducing the life of system components. Below is a chemical compatibility chart.

If you have any questions about chemical resistance to specific compounds, please contact Microlab Technologies Technical Support. Check out any unusual or reactive compounds before using them with your MICROLAB 600 system.

The following table contains information about chemical reactivity with the MICROLAB 600 system at room temperature.
