Whatman Mini-UniPrep syringeless filters with slit septa

General description
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 1/3 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 device 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 1/3 the time
Wide range of membrane choices from 0.2 and 0.45 μm pore sizes
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

Continuous Improvement and Innovation:
Whatman has listened to customers and created a whole family of Mini-UniPrep filters to meet specific needs. Customers who need to filter light sensitive samples can use the Amber Mini-UniPrep, customers using robotics to maximize throughput can use Slit Septa Mini-UniPrep.

Amber Mini-UniPrep Syringeless Filter

Features and Benefits:
Amber color 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

Features and Benefits:
Slit septum cap enables 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

Other Notes
Global SIAL customers (excluding Japan) can now order any product from the GE Healthcare Life Sciences consumables portfolio (prepack only) using GE′s product numbering system.

The legacy GE Whatman products that use the SIAL "Z" product numbering system will be discontinued and directly replaced with a product number using a "WHA" prefix plus the GE product code. For reference, the legacy "Z" product number is identified as a synonym on the "WHA" product number listing.
