Waters AF DG2 Inline Degasser 186001273

The Waters In-Line Degasser AF (P/N 186001273) is a high-performance 2-channel vacuum degasser designed for precision HPLC and liquid chromatography systems. Utilizing a Teflon® AF tubular membrane, this unit efficiently removes dissolved gases from mobile phases, improving system stability and analytical accuracy. Its built-in 2-head diaphragm pump operates in a zero-hysteresis, constant-run mode, minimizing baseline drift and ensuring consistent vacuum performance.

Ideal for demanding analytical labs, the degasser features broad chemical compatibility (pH 0–14), minimal internal volume (<0.5 mL per channel), and optimized flow ranges from 200 µL/min to 5 mL/min. Engineered with durable wetted materials (PPS, Teflon AF, Tefzel), this compact solution integrates seamlessly into existing systems. Includes external enable/disable control and DC output for real-time vacuum monitoring.

Specifications:
– Manufacturer: Waters
– Model: In-Line Degasser AF
– Part Number (P/N): 186001273
– Channels: 2-channel configuration (standard for this part number; some variants may support 3 or 4 channels)
– Degassing Method: In-line vacuum degassing using tubular Teflon® AF membrane
– Vacuum Source: Built-in 2-head diaphragm pump, resistant to solvents
– Pump Operation: Continuous cycling between high-speed (for rapid vacuum pull-down) and low-speed (to maintain steady vacuum); “zero hysteresis / constant-run” mode reduces baseline drift
