LVL Products Applications FAQ –
Biobanking, Cryo, Diagnostics & High-Throughput
LVL products such as SAFE® 2D tubes, SBS racks, closure systems, capper and decapper systems, and barcode readers are designed for demanding applications in modern laboratory environments. In this FAQ section, we answer key questions on biobanking, cryogenic applications, clinical diagnostics, pharmaceutical research, high-throughput screening, and regulated laboratory workflows.
LVL technologies systems support secure sample storage, automated processing, and digital traceability – from the unambiguous identification of individual samples to position-accurate tracking of entire SBS racks. Cryo-compatible materials, validated closure systems, standardized rack geometries, and LIMS-adjacent data integration reliably connect physical sample processes with digital documentation chains.
Particularly in biobanks, diagnostic laboratories, pharmaceutical research, and automated high-throughput processes, LVL products provide a stable foundation for reproducible, traceable, and scalable sample logistics.
Biobanking
Biobanks manage large volumes of samples over many years or even decades.
2D barcode-labeled tubes allow unambiguous, machine-readable identification of each sample and support consistent digital mapping within a LIMS system.
Biological samples are often stored at −80 °C or in liquid nitrogen down to −196 °C.
SAFE® 2D tubes are designed for cryogenic applications down to −196 °C.
In validation tests with 168 hours of LN₂ vapor exposure, no nitrogen ingress was detected. Mass loss was below 0.1%.
Material, threads, and seals remained functionally stable.
SBS-compliant racks and precise geometries allow SAFE® 2D tubes to be integrated into automated storage systems.
Simultaneous rack scanning enables rapid acquisition of entire units.
In pick-and-place tests with 3,465 cycles, an error rate of 0.086 % was measured.
Cryogenic Applications
At temperatures down to −196 °C, material, threads, and seals must remain dimensionally stable.
SAFE® 2D tubes are made from SAFE® L3 Medical Polypropylene, an additive-free polymer with low gas permeability and a homogeneous structure.
Micro-leakage or infiltrating nitrogen can compromise sample integrity.
SAFE closure systems use an axially acting TPE seal concept.
Sealing performance was validated at a defined torque of 7 Ncm (for SBS 96) and 15 Ncm (for SBS 48 and SBS 24).
No leakage was observed after 15 automated open/close cycles.
Clinical Diagnostics
In clinical diagnostics, unambiguous identification, rapid processing, and traceable documentation are essential.
2D DataMatrix tubes enable automated data capture and reduce manual entry errors.
Machine-readable identification, reproducible capping, and SBS-compliant geometry reduce operator variability.
The combination of unique ID and stable rack positioning supports consistent workflows.
Pharmaceutical Research
In preclinical studies and drug development, samples must be clearly assigned and reproducibly processed.
SAFE® 2D tubes support end-to-end digital traceability from screening to archiving.
Pharmaceutical processes are often highly automated.
SBS racks, capper and decapper systems, and rack readers enable integration into robotic and liquid-handling platforms.
Reproducible torque (validated at 7 Ncm for SBS 96 and 15 Ncm for SBS 48 and SBS 24) and dimensionally stable rack geometry support consistent operations.
High-Throughput Screening (HTS)
High-throughput screenings rely on standardized formats.
Only SBS-compliant systems ensure precise gripping, pipetting, and scanning processes with large sample volumes.
Simultaneous rack scanning reduces scan time.
Multi-channel capping supports parallel processes.
Precise dimensional accuracy and form-stable rack structure reduce mechanical misalignment.
Transfusion Medicine & Specialized Applications
In transfusion medicine applications, unambiguous sample assignment is essential.
2D DataMatrix tubes support secure identification and digital documentation of samples.
Unique ID generation, documented material properties, validated sealing systems, and LIMS integration support structured documentation workflows.
Laser marking can additionally provide permanent visual identification.
At extremely low temperatures, material stresses can occur.
Reinforced structure reduces the risk of positional shifts.
This is particularly important for rack readers and automated gripping systems, as position deviations can lead to scanning or handling errors.
Systemic Value
SAFE® components have been validated as a tube–cap–rack system.
Systemic coordination reduces potential interface risks between identification, storage, and processing.
This is particularly relevant in automated and regulated environments.
Each sample receives a unique digital identity.
Combined with standardized formats and stable rack positioning, this creates a system that consistently connects physical and digital workflows.
