MUHWA HPLC Vial Insert — Clear Plastic with Polyspring, 9-425, 200μL, 100 pcs/Pack, Fit 2mL Autosampler Vials

MUHWA HPLC Vial Inserts — 200μL, Polyspring, 9-425, 100 pcs/Pack

MUHWA 200μL plastic HPLC vial inserts enable low-volume injections (100-200μL) in standard 2mL autosampler vials. Each insert features a polyspring base that ensures proper seating and prevents flotation during needle penetration — a common cause of missed injections with poorly seated inserts. The clear plastic construction is lighter than glass, eliminating insert breakage during centrifugation. Compatible with all standard 9-425 2mL vials. 100 inserts per pack.

Key Features

• 200μL Fill Volume: Opitimized for 100-200μL sample volumes. Reduces dead volume compared to filling a full 2mL vial.
• Polyspring Base: Ensures the insert stays seated at the vial bottom. Prevents the insert from riding up the autosampler needle.
• Clear Polymer: Chemical-resistant to acetonitrile, methanol, water, and common HPLC mobile phases.

Applications

• Low-volume sample injections in standard 2mL vials
• Limited sample availability (natural products, clinical specimens)
• High-throughput screening where sample volume is constrained
