The Dräger WaterLock 2 (part number 6872130) is a water trap for Dräger sidestream gas monitoring that stops water, secretions and microbes from reaching the multi-gas sensor.
It uses two hydrophobic 0.2 µm PTFE membranes plus self-sealing safety filters, can be emptied with a standard syringe, and is rated for up to four weeks of use per unit. This box holds 12 units, which Dräger describes as roughly a one-year supply for a single workstation.
Why Choose the WaterLock 2 Water Trap
- Protects the gas analyser: Keeps condensate out of the multi-gas sensor, which helps avoid costly sensor repairs and downtime.
- Stable, accurate readings: Supports reliable CO₂, O₂ and anaesthetic agent readings, including during low-flow and minimal-flow anaesthesia when humidity in the sample gas is high.
- Infection control: The membrane barrier helps stop bacteria and germs entering the gas measurement system.
- Clear warning when blocked: The self-sealing filters turn blue when they are occluded, so staff know it is time to replace the water trap.
- Long service interval: Up to four weeks of use per trap, with the option to empty and continue during that period.
Key Features of the Dräger 6872130 Water Trap
Twin Hydrophobic PTFE Membranes
Two microporous PTFE membranes with 0.2 µm pores let sample gas pass while holding back liquid water and particles.
Self-Sealing Secondary Filters
A second protective stage seals itself if liquid gets past the membranes, stopping water from moving further into the monitor.
Syringe-Emptiable Reservoir
Collected fluid can be drawn off with a standard syringe, so the trap can stay in use for its full service life.
Optimised Housing Geometry
The housing is shaped for fast gas response and efficient drainage, which helps keep the capnography waveform accurate.
