Overview
The Festo VABS-K3-16S-20-N18-P is an intelligent, compact valve base module engineered for precision integration into automated life science fluidic systems. Designed as a core mechanical and interface platform for solenoid or pneumatic valves—particularly those conforming to the VABS modular valve system—it provides standardized mechanical anchoring, fluidic connectivity, and orientation flexibility in high-density laboratory automation environments. Unlike generic mounting plates, this base integrates functional design cues from ISO 8573-compliant pneumatic control architecture and microfluidic system integration standards. Its operation relies on passive mechanical coupling rather than active actuation; it serves exclusively as a structural and sealing interface between valve bodies and downstream manifolds or sample handling modules. The base enables bidirectional flow routing and supports both liquid and compressed gas media within defined thermal and chemical constraints, making it suitable for reagent dispensing, wash station manifolds, and analytical instrument fluid path conditioning in regulated laboratory settings.
Key Features
- PEEK (Polyetheretherketone) construction ensures dimensional stability, low moisture absorption, and compatibility with common laboratory solvents and cleaning agents—critical for repeated sterilization cycles and long-term exposure to aqueous buffers.
- 1/8 NPT internal thread interface guarantees repeatable, leak-tight connection to compatible valve bodies and tubing adapters under nominal pressure conditions up to 10 bar (per Festo VABS system specifications).
- Adjustable mounting orientation allows alignment optimization in constrained spaces—essential for robotic deck layouts where Z-height clearance and X-Y footprint are governed by ISO/IEC 61355-1 equipment classification standards.
- Single-valve-position configuration simplifies validation mapping and reduces potential failure points in GxP-compliant workflows requiring traceable fluid path segmentation.
- RoHS compliance and VDMA 24364 Category III PWIS (Paint Wetting Impairing Substances) certification confirm suitability for cleanroom-adjacent assembly and food-grade applications where extractables and leachables must be minimized.
- Lightweight design (26 g) minimizes inertial load on motorized stage carriers and contributes to dynamic performance in high-cycle automated platforms.
Sample Compatibility & Compliance
The VABS-K3-16S-20-N18-P is not a standalone analytical device but a certified mechanical interface component intended for use with Festo’s VABS-series miniature directional control valves (e.g., VABM, VABP). It exhibits full compatibility with aqueous solutions (including PBS, Tris-HCl, ethanol/water mixtures), medical-grade air, nitrogen, and CO₂ within its specified temperature range (0–50 °C medium and ambient). It is unsuitable for aggressive oxidizers (e.g., concentrated H₂O₂ > 6%), halogenated hydrocarbons, or strong alkaline solutions (>pH 12) due to PEEK’s inherent material limitations. Regulatory alignment includes adherence to EU Directive 2011/65/EU (RoHS), VDMA 24364 for surface cleanliness, and mechanical interface requirements outlined in ISO 13485:2016 Annex C for medical device manufacturing support equipment.
Software & Data Management
As a passive hardware interface, the VABS-K3-16S-20-N18-P does not incorporate embedded firmware, communication protocols, or data logging capabilities. Its integration into digital lab ecosystems occurs at the system level: when mounted with Festo’s electrically actuated VABM valves and connected via IO-Link or fieldbus modules (e.g., CPX-E), operational status—including valve position confirmation, cycle count, and diagnostic flags—is relayed through upstream PLCs or laboratory execution systems (LES). Audit trail generation for installation and maintenance follows GLP/GMP principles when documented within validated electronic maintenance logs compliant with FDA 21 CFR Part 11.
Applications
- Modular fluid path assembly in automated nucleic acid extraction workstations.
- Reagent selection manifolds in ELISA and immunoassay processors.
- Gas control interfaces for incubator and environmental chamber regulation subsystems.
- Point-of-use shutoff modules in liquid handling robots compliant with IEC 61000-6-2 EMC immunity standards.
- Validation-ready components for ISO 15197:2013-compliant in vitro diagnostic (IVD) instrument platforms.
FAQ
Is the VABS-K3-16S-20-N18-P rated for sterile filtration applications?
No—it is a mechanical interface only and does not provide filtration functionality or microbial retention capability.
Can this base be used with non-Festo valves?
Only if the mating valve conforms dimensionally and thread-spec-wise to the VABS-K3 standard; Festo does not guarantee performance or sealing integrity with third-party components.
Does the base require calibration or periodic verification?
No calibration is required, but visual inspection for thread damage and torque verification per maintenance SOPs is recommended before each reinstallation.
Is PEEK susceptible to gamma irradiation for terminal sterilization?
Yes—PEEK retains mechanical integrity after 25 kGy gamma exposure; however, validation per ISO 11137-2 is required for specific application contexts.
What documentation accompanies the unit for regulatory submissions?
Festo provides EU Declaration of Conformity, RoHS certificate, VDMA 24364 test report, and material safety data sheet (MSDS) upon request—no proprietary software or firmware documentation applies.
