Teflonkapillare | |||||
Teflon is translucent and for certain light sensitive applications we recommend to use black PTFE tubing. So far we recommend it for: - Light sensitive enzymatic reactions - Luminescent reactions - Connections for the flow-cell - Radioactive HPLC PFA Tubing PFA tubing (PerFluorAlkoxy) has excellent chemical stability and mechanical strength. Always use PFA instead of PTFE if gas permeability is the issue. 1/16" OD high purity tubing has a maximum pressure rating of up to 100 bar (1450 psi), while 1/8" OD maximum 72 bar (1050 psi). FEP Tubing FEP (FluorinatedEthylenePropylene) is chemically inert to most HPLC solvents and is recommended for low pressure applications. Typically 1/16" OD holds up to 117 bar (1700 psi) and 1/8" holds up to 70 bar (1000 psi). We recommend FEP for ion chromatography applications. We do not recommend using FEP tubing above 80°C. |
