General description
- 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
