PTFE Coated Needles
The PTFE coated needles are used for thin layer chromatography (TLC) and are coated with PTFE 3/4" up the needle from the tip. The coating reduces the surface tension between the needle and the liquid making it ideal for reproducible sample spotting. These needles are available as a removable needle (RN) small or large hub and will connect to the appropriate RN syringes.
