Simple, Innovative, Convenient

The Whatman Mini-UniPrep Syringeless Filters, now with a new durable plastic cap, provide a faster, easier way to remove particulates from samples being prepared for High Performance Liquid Chromatography (HPLC) 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 lab.

Mini-UniPrep is a pre-assembled filtration device 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 approved autosampler for injection into your instrument.

The device can be used either manually or with one of the compressor units available. The new 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 designed to accommodate 12 x 32mm 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 to process sample loads in one-third the time
• Wide range of membrane choices from 0.2 and 0.45µm pore sizes to meet specific sample application requirements
• Compatible with most major autosamplers. Allows for speeding processes
• Fewer consumables required. Lower costs by up to 40 percent.

Applications

• Routine 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 using robotics to maximize throughput, Whatman offers Slit Septa Mini-UniPrep. For customers who need to filter light sensitive samples, there is Amber Mini-UniPrep.

Amber Mini-UniPrep Syringeless Filter

Protects samples from UV damage.

Features and Benefits

• Amber colorant prevents photo degradation 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
