Item Number: WHA-US503NPEPP




For customers using robotics and requiring high-throughput automation, Whatman™ offers Slit Septa Cap Mini-UniPrep™ syringeless filter devices. Slit septum cap enables Mini-UniPrep use with current robotics on HPLC instruments for high throughput automation. These durable yet flexible slit septum caps have been specially designed for instruments with sensitive sampling needs. Sample evaporation is minimal. They may be used with standard robotics on HPLC instruments with sensitive needles, allowing for higher throughput. The Whatman™ Mini-UniPrep™ Syringeless Filters provide a faster and easier way to remove particulates from samples being prepared for High Performance Liquid Chromatography (HPLC) providing 67% time and 40% monetary savings for your laboratory. Mini-UniPrep™ is a preassembled syringeless filter consisting of a 0.4mL capacity chamber and a plunger. The plunger contains a filtration membrane at one end and a pre-attached 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 autosampler to contain 2mL vials for injection into your instrument. Processing samples through the syringeless filter can be performed either manually with the furnished plunger or with a compressor unit. The Mini-UniPrep™ 6 Six-Position Compressor (WHA-CR0000006) can process up to six samples at one time, further improving sample processing time and reducing the risk of hand stress. The Mini-UniPrep™ 1 Single-Position Compressor (WHA-CR0000001) processes single samples. The Mini-UniPrep™ device is designed to fit into any autosampler accommodating 12 x 32mm vials. Applications include routine HPLC & UHPLC analysis, composite assays, content uniformity, protein precipitation, solubility testing, dissolution testing and sample filtration. Cap: Slit Septum. Housing: Translucent. Filter Membrane: Polypropylene. Retention: 0.2µm. 1000/Pack. Whatman™ #: US503NPEPP.
