Product view · Illustrative reference
The closure is part of the sample container.
Match the cap to the vial neck first, then specify the septum construction required by your method. Include the solvent, temperature, sample residence time and number of needle punctures. Confirm formulation, facing layers and thickness for the exact supplied item.
Neck and cap format
A screw cap and a crimp cap use different sealing arrangements. Compare the nominal size with the vial drawing rather than matching by appearance.
Slit or slitless
The catalog offers both descriptions. Ask which design suits the sampler needle and the required seal after repeated injections.
Bonded construction
Bonded and non-bonded options are available within the range. Confirm the assembly and any method-specific cleanliness testing with your quotation.
