In this FAQ section, we answer key questions regarding selection criteria, internal vs. external threads, SBS formats, cryogenic storage, capping, LIMS integration, and product comparison.<\/p>\n<p>It is not just the individual 2D tube that matters, but the interplay of material quality, sealing, rack geometry, identification, and automation capability. For applications down to \u2212196 \u00b0C, validated sealing systems, low gas permeability, reproducible torque, and stable SBS structures are particularly important. At the same time, format choice, sample volume, throughput, and digital traceability must match the existing laboratory infrastructure.<\/p>\n<p>Especially in biobanking, pharmaceutical research, diagnostics, and high-throughput environments, a systematic selection of SAFE\u00ae components supports stable, traceable, and automatable sample processes.[\/vc_column_text][vc_empty_space][\/vc_column][\/vc_row][vc_row][vc_column][vc_custom_heading text=&#8221;Fundamental Selection Criteria&#8221;
