UVP PCR Workstation by Analytik Jena

Overview

The UVP PCR Workstation by Analytik Jena is an engineered containment solution designed specifically for nucleic acid amplification workflows requiring stringent contamination control. Unlike conventional laminar flow hoods or biosafety cabinets, this workstation operates as a closed, recirculating UV-irradiated enclosure—optimized for pre-PCR sample preparation, reagent aliquoting, and master mix assembly. Its core principle relies on germicidal ultraviolet irradiation (254 nm) to degrade residual DNA/RNA fragments on surfaces and in the internal air stream, thereby mitigating carryover contamination—a leading cause of false-positive results in quantitative PCR (qPCR), digital PCR (dPCR), and next-generation sequencing (NGS) library prep. The system does not exhaust to the external environment; instead, it maintains positive pressure within a sealed chamber while circulating air through optional multi-stage filtration (pre-filter + activated carbon + HEPA), ensuring both surface decontamination and airborne particulate removal. Built to meet the spatial and operational demands of modern molecular biology labs, it accommodates benchtop instruments and small peripherals via two adjustable stainless-steel sample racks.

Key Features

• Germicidal UV-C source (254 nm) with programmable timer (5 min – 12 hr) for validated surface and air decontamination
• Automatic UV interlock: UV lamps deactivate instantly upon front door opening, complying with IEC 60335-1 and EN 62471 safety standards
• Makrolon® polycarbonate front panel blocks 100% of UV radiation below 400 nm, protecting users from ocular and dermal exposure
• Antimicrobial-coated stainless steel and aluminum interior surfaces inhibit microbial adhesion and simplify wipe-down protocols
• Integrated touch-screen interface for centralized control of UV cycle, lighting, fan speed (if HEPA-equipped), and system status monitoring
• Two height-adjustable, removable sample racks for flexible placement of pipettes, centrifuges, tube racks, or thermal cyclers
• Internal incandescent task lighting and dual built-in 230 V AC power outlets (CEE 7/7) for seamless integration of lab instrumentation
• Modular design enables tool-free HEPA filter and UV lamp replacement—typical service time under 10 minutes
• Foldable frame allows full assembly in ≤20 minutes without specialized tools or technical support

Sample Compatibility & Compliance

The UVP PCR Workstation supports standard molecular biology consumables—including PCR tubes (0.2 mL, 0.5 mL), strip tubes, 96-well plates, microcentrifuge tubes, and low-binding reagent reservoirs. Its enclosed architecture eliminates cross-contamination between samples during open-tube handling steps. The system complies with ISO 14644-1 Class 5 (equivalent to Federal Standard 209E Class 100) when equipped with HEPA filtration. UV irradiation protocols align with recommendations outlined in CLSI EP29-A and ISO/IEC 17025 for environmental monitoring in accredited molecular diagnostic laboratories. Optional HEPA configuration meets ASTM F50-22 requirements for particle retention efficiency (>99.99% at 0.3 µm). All electrical components conform to CE marking directives (EMC Directive 2014/30/EU, Low Voltage Directive 2014/35/EU).

Software & Data Management

While the workstation operates independently without PC dependency, its embedded controller logs critical operational data—including UV exposure duration, cumulative lamp hours, door-open events, and error codes—for GLP-compliant recordkeeping. Audit trail functionality satisfies FDA 21 CFR Part 11 requirements when connected to a validated laboratory information management system (LIMS) via RS-232 or optional Ethernet module. No proprietary software installation is required; configuration and diagnostics are performed exclusively through the intuitive capacitive touchscreen interface, which retains user-defined presets across power cycles.

Applications

• Pre-PCR setup: template dilution, primer/reagent dispensing, master mix preparation
• Cloning workflow staging: restriction digest assembly, ligation reactions, transformation plate plating
• NGS library construction: fragmentation QC, adapter ligation, size selection setup
• Diagnostic assay development: validation of contamination-sensitive assays per CLIA and CAP guidelines
• Educational laboratories: teaching sterile technique and nucleic acid handling best practices
• Core facility environments: shared resource deployment where throughput and reproducibility are prioritized over personnel protection

FAQ

Does the UVP PCR Workstation provide personnel protection like a Class II biosafety cabinet?
No—it is not designed for biohazard containment. It provides product protection only, targeting nucleic acid contamination. For infectious agent handling, a certified biological safety cabinet remains mandatory.
Can the UV lamp be operated simultaneously with the HEPA fan?
Yes—UV irradiation and air filtration operate independently; both may run concurrently during decontamination cycles or separately during routine operation.
What is the expected lifetime of the 254 nm UV lamp?
Rated for ≥8,000 hours of operation under standard cycling conditions; output intensity is monitored automatically and flagged when degradation exceeds 20% of initial irradiance.
Is calibration required before first use?
No factory calibration is needed. However, users should perform initial UV intensity verification using a NIST-traceable radiometer to establish baseline performance per ISO/IEC 17025 Section 6.5.
How often must the HEPA filter be replaced?
Under typical usage (2–4 decontamination cycles daily), replacement is recommended every 12 months—or sooner if differential pressure exceeds 250 Pa, as indicated on the display.
