Conical Bottom Inserts:
Designed to concentrate samples at the bottom, reduce residues and maximize recovery. Ideal for trace analysis where every drop counts.
Flat Bottom Inserts:
Easier to clean and reuse, but may leave some residual liquid. Suitable for general storage and processing tasks.
Conical base with polymer spring inserts:
They provide additional stability to prevent tilting or movement within the vial, making them suitable for automated high-throughput analysis.
