Mini-UniPrep™ G2 Syringeless Filter Whatman

The Whatman™ Mini-UniPrep G2 syringeless filter simplifies UHPLC/HPLC sample
preparation over the traditional syringe filter method. The Mini-UniPrep G2 is an
all-in-one integrated filter that replaces the syringe, syringe filter, glass vial, cap,
and septum. After the filtration step Mini-UniPrep G2 can be placed directly into
the autosampler in readiness for injecting sample into the UHPLC/HPLC instrument.

 

The Mini-UniPrep G2 includes an integral borosilicate glass vial housed within the
plunger and a borosilicate glass chamber for holding the unfiltered liquid.
During the filtration step, the plunger is compressed into the glass chamber
containing the unfiltered liquid. As the plunger travels downward, liquid flows through
the filtration membrane to the top of the plunger and drops into the glass collection
vial housed within the plunger. Therefore, the sample only contacts plastic for a very
short period of time, that is only while the plunger is being compressed through the
unfiltered liquid. Once compressed, the Mini-UniPrep G2 is ready to be loaded directly
on to the autosampler.

 

Mini-UniPrep G2 comes in a number of configurations including slit septa for those auto-
samplers and robotic systems that require a slit septa. It is also available in amber for
light sensitive samples. Amber Mini-UniPrep G2 meets the requirements of the US
Pharmacopeia (USP) and European Pharmacopeia (EP) for light transmission.

 

Features of the Mini-UniPrep G2:

  • Consists of an integral borosilicate glass autosampler vial, plunger with attached
    filter membrane, and septum/cap
  • Filters samples faster compared to the traditional syringe filter method
  • Glass construction minimizes the risk of leachables contaminating the sample
  • Designed to be loaded directly into the autosampler
  • Includes visual indication that the sample has been filtered
  • Minimizes instrument downtime due to unfiltered samples
  • Wide range of membranes with 0.2 and 0.45 μm pore sizes to meet specific sample
    filtration requirements
