The new National Target DP 9mm closures are designed to help chromatographers achieve more reliable and efficient sample analysis. Designed to accommodate nearly all chromatography autosamplers fitted for 12 × 32cm vial trays, the C5000 series closure effectively eliminates septa push-through and significantly enhances productivity and flexibility in the laboratory. At the core of the National Target DP 9mm C5000 series of closures is the Advanced Vial Closure System technology. Simply stated, AVCS allows your closure to perform like never before. The C5000 series closures are fully compatible with all of the C4000 series Target DP 9mm vials.

Features of Target DP 9mm Vial Closures:

• Septa push through nearly eliminated due to improved interior geometry
• Increased sealing capability
• AVCS provides the freedom to select the best septum for your instrument and applications
• Cost efficient alternative to current choices for resolving push through (bonded septa)
• Optimized ergonomics, fine texturing and evenly spaced ribbing for superior handling even with poorly fitting gloves
• Rough edges have been eliminated making it easier and more comfortable to use while improving autosampler operation

National C5000 Series Target DP 9mm Wide Opening 9mm Closure

• A wide opening vial deserves a wide opening closure. Utilizing AVCS technology, the C5000 series wide opening closure increases the available injection area by over 7% providing greater area for injection needle penetration.

National C5000 Series Target DP 9mm Integral Membrane Closure

• In addition to AVCS technology, the C5000 series closure provides a halogen and rubber-free sample handling environment for HPLC applications or applications where silicones and rubber septa are not suitable.

National C5000 Series Target DP 9mm Solid Closure

• AVCS technology provides maximum protection of samples during long term storage. The protective top prevents accidental puncture of the septum and resulting sample loss. Can be stored down to -80°F.
