General description
Transform your HPLC and UHPLC sample preparation with our Mini-UniPrep® syringeless filters. These filters combine four steps into one to offer a fast, efficient, and environmentally friendly solution to sample filtration prior to chromatography.
Chromatography sample preparation steps traditionally involve multiple consumables like syringe filters, vials, and septa, which increases costs and time required for sample filtration. Mini-UniPrep® syringeless filters eliminate the need for these separate disposable components and prepare samples in one-third the time required by other methods used for high performance liquid chromatography.
By excluding large particles from a chromatography sample, the time required to process the mobile phase is shortened and HPLC column life is extended by reducing contamination that causes clogging and back pressure build up.
Mini-UniPrep® syringeless filters can be used either manually or with a multicompressor. The multicompressor allows for processing of multiple filtration samples, further reducing sample preparation time for chromatographic analysis.
Using the Mini-UniPrep® syringeless filter is easy. If you are not using a multicompressor, simply place your sample in the Mini-UniPrep® device, insert the plunger, and compress. Your sample is filtered rapidly and easily. The unique design allows the liquid sample to be forced into the reservoir of the plunger. Any excess air escapes though the vent hole until the seal is engaged. The Mini-UniPrep® syringeless filter can then be used in an autosampler.
Application
- Routine HPLC/UHPLC analysis
- Composite assays
- Content uniformity
- Protein precipitation
- Solubility testing
- Dissolution testing
- Sample filtration
Features and Benefits
- 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.
