Description

Produced with the same colorant used in pharmaceutical containers. Whatman™ Mini-UniPrep™ Amber Syringeless Filters provide an easier way to remove particulates from HPLC/UHPLC samples in one-third the time as compared to traditional syringe filters.

Whatman Mini-UniPrep™ Amber Syringeless Filters quickly and easily remove particulates from light-sensitive samples being prepared for HPLC/UHPLC analysis, while meeting USP specifications for light resistance.

• Pre-assembled all-in-one filtration unit eliminates the need for syringe filter, syringe, vial and septum, reducing costs by up to 40%
• Wide range of membrane choices in 0.2 and 0.45 μm pore sizes to meet specific sample application requirements
• Compatible with most major autosamplers for high-throughput analysis
• Fewer consumables required
• Plunger contains a filtration membrane at one end and a pre-attached cap/septum at the other
• Can be used either manually or with a compressor unit
• Multi-sample compressor processes up to 6 samples at a time, further improving sample processing time and reducing hand stress
• Designed to fit into any autosampler accommodating 12 x 32mm vials -OR-
  Septum can be pierced with needle and sample drawn off for manual injection into an analyzer

Compliance

Meet USP specifications for light resistance.

Multi-sample compressor can process up to six samples at one time, further improving sample processing time.
