GE Amersham Flow Restrictor FR-904 18111963 SKU: 8994 Manufacturer: GE Amersham / Cytiva Model: Flow Restrictor FR-904 Item number: 18111963 Device Type: Flow Limiter (Flow Restrictor) Description: The GE Amersham FR-904 Flow Restrictor (item no. 18111963) is a precise flow restrictor specifically designed for use in liquid chromatography and protein purification systems –such as ÄKTA™ systems. It is used to precisely control the flow and back pressure within chromatographic systems and is a crucial element in maintaining stable working conditions in HPLC or FPLC applications. The FR-904 is particularly suitable for sensitive separation processes where the back pressure must be kept constant to protect the integrity of columns and samples. The compact design with standardized connection dimensions enables easy integration into existing chromatography setups. Specific details: Application: Liquid chromatography (FPLC/HPLC), protein purification Function: Maintaining back pressure and limiting flow Compatibility: Ideal for GE ÄKTA systems (Explorer, Pure, Prime, etc) Technical details: Max pressure: up to 6 MPa (depending on system configuration) Flow rate: typically tuned for 0.1–10 mL/min (model dependent) Material: High quality stainless steel / PEEK Connection thread: UNF 10-32 (standard FPLC thread) Dimensions (L × Ø): approx. 30 mm × 6 mm Weight: approx. 15 g Condition: The FR-904 is in very good condition. The component shows no external damage or deposits, is ready for immediate use and is ideal as a replacement or extension part for existing chromatographic Systems.
