GE Healthcare Mini-UniPrep™ Pre-Assembled Filtration Devices

Syringeless filters consisting of a 0.4 ml 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 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 analyser. - Amber colourant prevents photodegradation of light sensitive samples (e. g. catecholamines, vitamins). Same colourant used in pharmaceutical containers designed to meet USP specifications for light resistance. Translucent amber chamber and plunger enable easy visual inspection. - Slit septum cap enables Mini-UniPrep™ use with current robotics on HPLC instruments for high throughput automation. Durable yet flexible slit septum cap has been specially designed for instruments with sensitive sampling needs. Sample evaporation is minimal. Applications: - Routine HPLC analysis. - Composite assays. - Content uniformity. - Protein precipitation. - Solubility testing. - Dissolution testing. - Sample filtration.
