Chemical Compatibility Chart

This Chemical Compatibility Chart is provided as a quick reference for determining likely compatibility issues with various materials. Each application presents
different possible chemical interactions. Before permanent installation, test equipment with the intended chemicals under the specific conditions of your
application.
The information provided in this chart has been supplied to Tecan Systems by other reputable sources and is to be used only as a guideline. Tecan Systems
does not warrant, either expressly or by implication, that the information in this chart is accurate or complete, nor that the materials are suitable for any particular
purpose.

Caution! Failure to test chemicals used in individual applications may result in damage to the pump and/or test results.

DANGER! Variations in chemical behavior during handling due to factors such as temperature, pressure and concentration can cause
equipment to fail, even if it passed initial testing. SERIOUS INJURY MAY RESULT. Use suitable guards and/or personal protection
when handling chemicals.

Table 1 Wetted Materials Used in Tecan Pumps

Telfon® (PTFE, TFE, FEP) Ceramic (Alumina) UHMWPE Valve body Valves and syringes
Kel F® Polypropylene Tubing, valve plug, syringe seals Fittings for tubing Long-life syringe seals

Ratings – Chemical Effect

The following letter codes are used in Table 2 to indicate these ratings:
A = Excellent.
B = Good – Minor Effect, slight corrosion or discoloration.
C = Fair – Moderate Effect, not recommended for continuous use. Softening, loss of strength, swelling may occur.
D = Severe Effect, not recommended for ANY use.
N/A = Information not available.

Explanation of Footnotes
Numbers associated with letter ratings in Table 2 provide thermal performance ranges.
1. Satisfactory to 72°F (22°C)
2. Satisfactory to 120°F (48°C)
For example, an entry that reads “A1” indicates a chemical effect of “Excellent” and a thermal performance range of up to 72°F (22°C).
