Frit sealing
WebSealing with glass frit is a well-known industrial technique allowing the best hermeticity of the sealed devices; requires, however, high process temperature (> 380 °C) [5], not compatible with PSC. Localized laser-assisted sealing can be used to encapsulate PSC devices with glass frit at much lower temperatures (< 130 °C) [6]. Webrings, piston seals, wash seals and gaskets as applicable) Note: for Agilent 1290 Infinity and Infinity II pumps, this task will only be performed for Easy Maintenance and Long Life pumps. • Replace seal wash peristaltic pump (if applicable) • Replace PTFE frit for purge valve and replace seal cap assembly in pump
