Liquid-Handling Products FAQ –
Consumables, Precision & Automation Compatibility
Liquid-Handling products and consumables from LVL technologies complement SAFE® 2D tubes and SBS racks to form a coordinated system for precise, automatable sample handling. In this FAQ section, we answer key questions on liquid handling, SBS compatibility, material quality, chemical resistance, sealing solutions, automation capabilities, and regulatory requirements.
These products are designed for reproducible laboratory workflows – from secure sample storage to transfers and aliquoting, up to processing in automated screening or diagnostic workflows. Standardized SBS formats allow liquid-handling products to integrate seamlessly into pipetting robots, rack systems, automated storage solutions, and LIMS-adjacent processes.
Particularly in biobanking, pharmaceutical research, molecular diagnostics, and high-throughput screening, LVL consumables support accurate dosing, stable material properties, and traceable sample processing within validated laboratory environments.
Basics & System Integration
This area includes tubes, rack-compatible components, plate solutions, as well as suitable closure and sealing systems.
The goal is precise and automatable liquid handling within standardized SBS formats.
SBS standardization enables integration into:
- Pipetting robots
- Automated storage systems
- Screening platforms
- Robotics solutions
Only standardized geometries ensure reproducible movement and gripping processes.
While SAFE® 2D tubes secure identification and storage, liquid-handling products enable precise sample processing – for example during transfers, aliquoting, or reaction setups.
Coordinated geometries reduce interface risks between identification, storage, and processing.
Material & Quality
High-quality, chemical-resistant polymers are used – in particular SAFE® L3 Medical Polypropylene for compatible components.
The material is additive-free and has a homogeneous polymer structure.
Analytical tests using:
- GC-MS
- LC-MS
- ICP-MS
showed no relevant leachables or extractables, and no detectable heavy metals above the detection limits.
Adsorption can lead to sample loss, especially at low concentrations.
In validation tests over 4 weeks at −20 °C, SAFE® L3 polypropylene demonstrated very low protein binding compared to reference products.
This is particularly important for sensitive biological samples.
For molecular biology applications, certified variants are available that are free of DNase and RNase.
This supports low-contamination workflows in diagnostics and research.
Sealing & Safety
Heat-sealing films provide secure sealing of plates.
They reduce evaporation and minimize contamination risks during storage or transport.
Special sealing solutions are designed for low temperatures.
Depending on the product, applications down to −80 °C or lower are possible. Suitability depends on the specific material type.
Precisely manufactured tubes, defined sealing geometries, and compatible rack systems reduce the risk of leakage.
Reproducible capping with defined torque further supports sealing stability.
Automation & Workflow
Yes.
SBS-compliant geometries and precise dimensional accuracy enable integration into automated liquid-handling and screening systems.
In high-throughput environments, pipette tips and gripping systems must be positioned precisely.
Deviations in geometry or material warping can cause process errors.
Dimensionally stable materials and precise manufacturing support reproducible workflows.
Yes.
Combined with 2D DataMatrix tubes, rack readers, and digital ID management, a seamless process from identification through processing to archiving is achieved.
Applications & Use Cases
Typical use cases include:
- Biobanking
- Pharmaceutical research
- Molecular diagnostics
- High-throughput screening
Anywhere precise, automated, and documentable sample handling is required.
Standardized formats, documented material properties, and compatible identification systems support structured documentation processes in GMP- or ISO-adjacent environments.
A systemically coordinated SAFE® setup reduces potential interface risks between storage, identification, and processing.
Material, geometry, and automation compatibility are aligned to support reproducible workflows.
