Product Description
The Whatman UniPrep Syringeless Filter | UN113UAQU is a premium-quality PVDF syringeless filtration device designed to simplify laboratory sample preparation by combining a filter, plunger, and sample vial into a single disposable unit. Featuring a 0.45 µm low protein-binding PVDF membrane, this filter provides efficient clarification of aqueous and aqueous-organic samples while minimizing sample loss. It is an excellent solution for pharmaceutical, biotechnology, analytical, environmental, and research laboratories seeking fast, contamination-free sample preparation.
Unlike conventional syringe filters, the UniPrep device eliminates the need for a separate syringe. The sample is placed directly into the integrated vial, and the filter-plunger is pressed through the liquid, forcing the filtrate into the plunger reservoir. This innovative design reduces preparation time, minimizes laboratory waste, and lowers the risk of contamination. The built-in glass microfiber prefilter efficiently removes larger particles before they reach the PVDF membrane, helping prevent membrane clogging and ensuring consistent filtration performance.
The UN113UAQU model is designed for filtering 1–5 mL sample volumes and features a 0.45 µm PVDF membrane with low protein binding, making it suitable for protein-containing samples, HPLC sample preparation, pharmaceutical dissolution testing, biotechnology research, and routine laboratory filtration. The chemically resistant polypropylene housing provides durability while maintaining sample integrity. Supplied in packs of 50, the filter is ideal for laboratories performing high-throughput analytical workflows.

FAQs
What is the shelf life of Whatman Uniprep Syringeless Filters?
When stored in their original packaging, these filters typically have a shelf life of 2–3 years. Always check the expiration date on the pack.
Can I autoclave these filters?
No, these are single-use, sterile filters and should not be autoclaved. Dispose of them after one use to maintain sample integrity.
Are these filters compatible with all HPLC vials?
Yes, they are designed to fit standard 1.5mL HPLC vials, ensuring broad compatibility with most systems.
How do I choose between 0.2µm and 0.45µm filters?
Use 0.2µm for sterilization or fine particulate removal and 0.45µm for general clarification or pre-filtration.
