Mini-UniPrep in
an HPLC autosampler
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)/ 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 able to contain 2 ml vials 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.
Features and benefits
- 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. Reduce costs by up to 40%
Applications
- Routine HPLC/UHPLC analysis
- Composite assays
- Content uniformity
- Protein precipitation
- Solubility testing
- Dissolution testing
- Sample filtration
A variety of Mini-UniPrep filters to meet your needs
In a process of continuous improvement and innovation, Whatman has listened to customers and created a whole family of Mini-UniPrep filters to meet specific needs. For customers who need to filter light sensitive samples, there is Amber Mini-UniPrep. For customers using robotics to maximize throughput, Whatman offers Slit Septa Mini-UniPrep.
Amber Mini-UniPrep Syringeless Filter
Protects samples from UV damage.
Features and benefits
- 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
Applications
- Use with any compound that requires protection from light, such as catecholamines or vitamins
Slit Septa Mini-UniPrep Syringeless Filter
For high-throughput automation
Features and benefits
- 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
- Use with standard robotics on HPLC instruments with sensitive needles, allowing for higher throughput
