General description

The Whatman Mini-UniPrep G2 is an all in one device that functions both as a filter and a glass autosampler vial for sample preparation prior to UHPLC/HPLC.

  • Liquid stored in glass, reducing leaching (specially with organic solvents)
  • Works well for aqueous based samples
  • Sample only contacts plastic during the actual act of compression
  • Improved solvent evaporation rates
  • Process samples 3X faster than traditional syringe filter method
  • All-in-one device replaces multiple consumables
  • Reduce lab waste
  • Simplify ordering
  • Fewer consumables to store in lab
  • Designed to fit any autosampler that accommodate standard 12 x 32 mm vials

Features and Benefits

  • Features an integrated autosampler vial, plunger with attached filter membrane, and septum/cap
  • Borosilicate glass vials eliminate plastic-based leachables that can originate from polypropylene vials
  • Designed to hold up to 0.5 mL of unfiltered sample that can then be loaded directly into an autosampler
  • Easy to see when a sample has been filtered
  • Wide range of membranes with 0.2 and 0.45 µm pore sizes to meet specific requirements
  • Also available in amber glass for light-sensitive samples

Vinculin is filamentous (F)-actin-binding protein enriched in integrin-based adhesions to the extracellular matrix (ECM). Whereas studies in 2-dimensional (2D) tissue culture models have suggested that vinculin negatively regulates cell migration by promoting cytoskeleton-ECM coupling to strengthen and stabilize adhesions, its

Blood-brain barrier function is driven by the influence of astrocyte-secreted factors. During neuroinflammatory responses the blood-brain barrier is compromised resulting in central nervous system damage and exacerbated pathology. Here, we identified endothelial netrin 1 induction as a vascular response to

In skeletal muscle, intracellular Ca(2+) is an important regulator of contraction as well as gene expression and metabolic processes. Because of the difficulties to obtain intact human muscle fibers, human myotubes have been extensively employed for studies of Ca(2+)-dependent processes

Invasive colorectal cancer is associated with poor prognosis requiring treatment with systemic chemotherapies usually including 5-fluorouracil. A consequence of prolonged treatment is the acquisition of resistance eventually resulting in the recurrence of highly metastatic cancer cells. To address the relationship
