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 […]
Have RSA™ Vials been discontinued and did RSA-Pro™ change its name to RSA-Pro X™? No, RSA™ Vials are non surface treated, hydrophilic, borosilicate glass vials that do not adsorb basic compounds as do all other borosilicate glass vials. They are still available, one of the most popular vials in the market today and are still […]
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 […]
What is the difference between RSA-Pro™ vs the new RSA-Pro X™? The biggest difference is that RSA-Pro™ surface treatment was a vapor deposition process that used ionic bonds with silanes to achieve hydrophobicity of the RSA Glass and RSA-Pro X™ uses a very different, proprietary process of covalently bonding hydrophobic materials to the walls of […]
