PTFE-Free Visiprep™ SPE Vacuum Manifolds by Supelco: Minimize PFAS Contamination & Streamline SPE Sample Preparation

Achieving low-background contamination is crucial for PFAS testing. The new PTFE-Free Visiprep™ SPE Vacuum Manifolds for PFAS Testing by Supelco use advanced, PTFE-free materials to prevent PFAS interference, meeting rigorous analytical and regulatory demands. Explore how these manifolds can enhance your solid phase extraction workflows for reliable, high-throughput sample preparation.

Benefits of PTFE-Free Visiprep™ SPE Vacuum Manifolds

• Lower PFAS background risk: Supports PFAS testing workflows by minimizing PFAS background contamination during sample preparation.
• Higher sample throughput: Processes 12 or up to 24 samples simultaneously to increase throughput for solid phase extraction sample preparation and cleanup.
• Reduced hands-on time: Semi-automates solid phase extraction and decreases hands-on time compared with liquid-liquid extraction (LLE) methods.
• Controlled, reliable processing: Enables precise flow control during extraction to support consistent, controlled sample processing across multiple ports.
• Safer, easier workflow handling: Provides safe and easy use with a cover design that can be set aside during workflow steps without compromising ease of handling.
• Streamlined drying across many samples: With the Visidry™ Drying Attachment, dries up to 12 or 24 SPE tubes at one time to improve efficiency in multi-sample workflows.
• Independent gas control per tube: Allows gas flow through each port to be independently adjusted for controlled drying and processing.
• Added flexibility after elution: Supports evaporation and concentration of recovered samples when using the Visidry™ Drying Attachment.

Application and usage

• Primary application: Use PTFE-Free Visiprep™ SPE Vacuum Manifolds and accessories to semi-automate the preparation and cleanup of laboratory liquid samples by solid phase extraction (SPE) in sample preparation processes within the PFAS testing workflow.
• Vacuum manifold operation: Connect the Visiprep™ manifold to a vacuum pump to process 12 samples (12-port model) or up to 24 samples (24-port model) simultaneously by SPE.
• Flow control during SPE: Use the vacuum bleed valve and stand-alone cover for flow control, and adjust flow through each tube by rotating the individual screw-type valves built into the cover.
• SPE tube handling on the bench: When the cover is removed from the vacuum manifold, set it on the work surface using the integrated legs while keeping the SPE tubes upright.
• Collection vessel setup: Position collection vessels in the manifold rack, which accommodates autosampler vials, small scintillation vials, 10 and 16 mm test tubes, and 1, 2, 5, and 10 mL volumetric flasks.
• Optional vial plate: For 24-port models, use the optional plate designed for 20 mL scintillation vials.
• Optional drying and concentration step: Install the Visidry™ Drying Attachment (sold separately) in minutes on Visiprep™ Vacuum Manifolds and connect it to any inert gas supply to dry up to 12 or 24 SPE tubes at one time.
• Gas control per port: Independently adjust gas flow through each Visiprep™ port when using the Visidry™ Drying Attachment.
• Evaporation and concentration use: Use the Visidry™ Drying Attachment to evaporate and concentrate recovered samples, in addition to drying SPE tubes.
