Mini-UniPrep Syringeless Filter

A preassembled filtration device which provides a faster and easier to prepare samples for HPLC and UHPLC analysis.

• All-in-one filtration process allows you to process sample loads in one-third the time.
• Wide range of membrane choices from 0.2 and 0.45 µm pore sizes to meet specific sample application requirements.
• Compatible with most major autosamplers.
• Fewer consumables required. This all-in-one device eliminates the need for syringe filter, syringe, vial and septum. Reduce costs by up to 40%.
• Amber colorant prevents photodegradation of light sensitive samples.
• Same colorant used in pharmaceutical containers designed to meet USP specifications for light resistance.
• Translucent amber chamber and plunger enable easy visual inspection.

Mini-UniPrep Syringeless Filters provide a faster and easier way to remove particulates from samples being prepared for High Performance Liquid Chromatography (HPLC)/Ultra High Performance Liquid Chromatography (UHPLC) analysis. In fact, Mini-UniPrep lets you prepare samples in one-third the time required by other methods. Add up the time savings, plus the money saved from cutting multiple consumables out of the sample preparation process and you'll see huge benefits for your laboratory.

Mini-UniPrep is a preassembled filtration device consisting of a 0.4 ml capacity chamber and a plunger. The plunger contains a filtration membrane at one end and a preattached cap/septum at the other. The plunger is pressed through the sample in the outer chamber and positive pressure forces the filtrate into the reservoir of the plunger. Air escapes through the vent hole until the locking ring is engaged, providing an air-tight seal. Within seconds the Mini-Uniprep can be placed into any approved autosampler for injection into your instrument.

The device can be used either manually or with a compressor unit. The multi-compressor can process up to 6 samples at one time, further improving sample processing time and reducing the risk of hand stress. The Mini-UniPrep device is designed to fit into any autosampler accommodating 12 x 32 mm vials. Alternatively, the septum can be pierced with a needle and the sample drawn off for manual injection into an analyzer.
