Low Pressure Fittings
Stainless Steel Last Drop Mobile Phase Filter, Stepped Tubing Connector, 10 µm, 30 ml/min
- No loss of mobile phase
- Biocompatible PTFE frits or stianless steel frits
- Three porosity options
- Two connector types: stepped tubing and 1/4-28 fitting
The Last Drop mobile phase filter allows more analyses per batch of mobile phase and helps reduce hazardous waste. The flat filter element sits parallel to the bottom of the reservoir, allowing the Last Drop to filter all but the last 2% of the mobile phase from the reservoir without drawing air into the system. Compare this with conventional cylindrical filters that can begin to draw air into the system when nearly 10% of the solvent remains in the reservoir.
The Last Drop mobile phase filter consists of a 316 stainless or PTFE 2.5 µm filter element pressed into an inert PTFE housing. The top of the housing has a 1/4-28 nut and ferrule or a stepped PEEK fitting connector which slips into 1.5, 2.2, or 3.5 mm ID pump inlet lines.
