The Whatman Mini-UniPrep Syringeless Filters combine four products into one syringeless filter solution for efficient chromatography sample preparation for a broad range of applications. They are built for fast and easy high performance liquid chromatography/ultra high performance liquid chromatography sample preparation and analysis.

• All-in-one filtration device for quick and cost-effective chromatography sample processing
• Eliminates the need for separate syringes, syringe membrane filters, vials, and septa
• Designed for use with an UHPLC or HPLC autosampler for high-throughput analysis
• 0,2 µm and 0,45 µm filter pore sizes available to meet filtration sample requirements
• Compatible with most major autosamplers
• Housing options: amber to prevent photodegradation of light-sensitive samples, or translucent for easy visual inspection made from polypropylene (PP) material
• Recyclable after use

By excluding large particles from a sample, the time required to process the mobile phase is shortened. Also, column life is extended by reducing contamination that ultimately causes clogging and back pressure build up.
Applications include: Routine HPLC/UHPLC analysis, composite assays, content uniformity, protein precipitation, solubility testing, dissolution testing and sample filtration. Use with any compound that requires light protection, such as catecholamines or vitamins.

These filters can be used either manually or with a compressor unit. Compressor units allow for processing of multiple samples, further reducing sample preparation time for chromatographic analysis.
