Mini UniPrep Vials - syringless filters PVDF Filters

These preassembled filtration devices offer a faster, easier way to prepare samples for HPLC and UHPLC analysis.

The all in one filtration system turns into the vial for direct loading into auto-samplers - saving up to 40% in costs and up to 33% in time!

• Wide range of membrane materials and pore sizes available
• Compatible with most major autosamplers
• Fewer consumables needed - one Mini Uniprep takes the place of separate syringe filter, syringe, vial and septum
• Amber versions available for light sensitive samples
• The amber colorant is used in pharmaceutical containers to meet USP specifications on light resistance
• Fast, visual check on whether samples have been filtered before analysis
• Slit Septum cap versions for use with robotics systems on HPLC instruments

How does it work?

The Mini UniPrep comes pre-assembled and comprises of a 0.4ml capacity chamber and plunger. The plunger has a filtration membrane fitted at one end, and a preattached cap/septum at the other.

When the plunger is pressed through the sample in the outer chamber (by hand or using a multi-vial compressor) the pressure forces the filtrate through the filter into the reservoir of the plunger. Air escapes through the vent hole until the locking ring is engaged, giving an air tight seal.

Within seconds the Mini UniPrep is ready to load into the autosampler.
