FlatLine Pulse Damper
-
Rupture proof Pulse Damper with no diaphragm
-
Flow path geometry combines clean flush out with minimal internal volume
-
Custom sizes available for OEM
-
FlatLine HC (High Capacity) increases damping efficiency and range
-
Can be manufactured to include a pressure transducer and/or a prime purge valve
-
The ASI FlatLine Pulse Damper combines performance and reliability in a simple, easy to use housing. Standard 10-32 inlet and outlet ports allow quick connection into virtually any HPLC system. Solid core technology provides reliable long term operation without the down time associated with ruptured or leaking membrane dampers. Custom sizes and additional features like integral prime/purge valve available for the OEM market.
Although similar to the standard ASI FlatLine Damper, the HC (High Capacity) features a bimodal damping mechanism which includes solid core and dynamic spring deflection. This combination increases damping efficiency over a wider pressure range. The HC is particularly well suited for damping at low pressures, below 500 PSI.
