Yes, the ends of the Pre-Cut SS tubing are polished. They are flat, burr free and have a clean polished finish making them perfect for HPLC. Click HERE for High Pressure Tubing Ordering Information.
The closest tubing we recommend would be low pressure use, FEP or PTFE. PTFE has micro-pores, and proteins may ‘creep’ in there. FEP is preferred because it has the same chemical stability but without the micro-pores. However, you would have to test it for your proteins as we could not guarantee it would be appropriate […]
We have a useful Pressure Calculator on our website in which you determine the contribution your tubing ID will bring to the overall back pressure in your system. This can be handy when you are setting up an HPLC system and want to know what ID tubing would be best to use. The lower the […]
Use of a strongly basic Mobile Phase is not recommended for any Silica based HPLC Column because the underlying Silica of the Stationary Phase is prone to dissolution at pH above 8 when the solution has a strong ionic strength. This may seem problematic for some analytes that you want to use in Aqueous Normal […]
