Mobile Phase Filters and Spargers
Last Drop mobile phase filter
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 filter element
pressed into an inert PTFE housing. The top of the housing has a PEEK tripod
which slips into 1.5, 2.2, or 3.5 mm ID pump inlet lines. It will also work with our
1/16" and 1/8" flangeless fittings.
Use the metal-free PTFE version for sensitive biochromatography applications
where metal surfaces may corrode or interact with samples.
