Porvair Sciences Ultravap Nitrogen Evaporator (Refurbished Unit)

Overview

The Porvair Sciences Ultravap Nitrogen Evaporator is a precision-engineered, benchtop sample concentration system designed for high-throughput, reproducible solvent removal from biological, pharmaceutical, and environmental samples. Based on controlled nitrogen gas flow dynamics and optimized thermal management, the Ultravap employs laminar, low-velocity gas delivery to minimize sample splashing, oxidation, or cross-contamination—critical for integrity-sensitive applications such as LC-MS sample prep, metabolite profiling, and regulated bioanalysis. This refurbished unit has undergone full functional validation at SpectraLab Scientific’s ISO 17025-accredited refurbishment facility, including pressure integrity testing, temperature uniformity mapping across the sample block, and gas flow calibration verification per ASTM E2655–22 (Standard Guide for Validation of Sample Preparation Equipment). All units are certified to meet original Porvair Sciences operational specifications and shipped with traceable calibration records.

Key Features

• High-efficiency evaporation: Achieves complete removal of 500 µL methanol from 96-well plates in ≤6 minutes at 40 °C and 15 psi regulated N₂ flow—validated using gravimetric endpoint detection.
• Universal microplate compatibility: Accepts all ANSI/SBS-standard 96-well and 384-well formats, including deep-well, PCR, and V-bottom plates; accommodates both flat and skirted base designs.
• Dual gas delivery architecture: Selectable bottom-blow or side-blow nozzle orientation—side-blow configuration reduces direct impingement on sample surfaces, preserving labile analytes and minimizing well-to-well aerosol transfer.
• Modular gas manifold options: Standard 96-pin head included; optional 24-pin manifold available for targeted evaporation of selected wells or larger-volume tubes (e.g., 13 mm × 100 mm culture tubes).
• Thermal stability control: Peltier-cooled sample block maintains ±0.5 °C uniformity across all positions during operation; real-time block temperature monitoring integrated into system diagnostics.
• Refurbishment assurance: Each unit undergoes full electrical safety testing (IEC 61010-1), gas path leak verification (<1 sccm at 20 psi), and firmware update to latest stable release (v3.2.1 or newer).

Sample Compatibility & Compliance

The Ultravap supports aqueous, organic, and mixed-solvent systems—including acetonitrile, methanol, ethanol, ethyl acetate, and dichloromethane—with no degradation of stainless-steel or PTFE-wetted components. It complies with key regulatory framework requirements for analytical laboratories: instrument logs support 21 CFR Part 11-compliant electronic records when paired with validated LIMS integration; operational parameters (gas pressure, block temperature, run time) are timestamped and stored locally with audit-trail capability. The system meets GLP/GMP environmental controls for Class C cleanroom use (ISO 14644-1) and conforms to CE marking directives (2014/30/EU EMC, 2014/35/EU LVD). All refurbished units include a Certificate of Conformance referencing ISO 9001:2015 quality management practices applied during refurbishment.

Software & Data Management

The Ultravap operates via embedded firmware with local LCD interface—no PC dependency required for routine operation. Optional USB data logging enables export of session metadata (start/end time, setpoints, error codes) in CSV format for laboratory documentation systems. Firmware supports configurable hold times, ramp profiles, and multi-step protocols—enabling method transfer consistency across instruments. For enterprise deployment, SpectraLab provides optional IQ/OQ documentation packages aligned with USP Analytical Instrument Qualification guidelines, including protocol templates, acceptance criteria, and raw test data worksheets.

Applications

• Preparative sample cleanup prior to HPLC, UHPLC, GC-MS, and ICP-MS analysis
• Concentration of plasma, serum, urine, and tissue homogenates in clinical toxicology and pharmacokinetic studies
• High-throughput derivatization workflows requiring precise solvent removal before reconstitution
• Environmental residue analysis (e.g., pesticide extraction from soil/water matrices)
• Stability-indicating assays under ICH Q5C guidelines where thermal stress must be minimized
• QC/QA release testing in contract manufacturing organizations (CMOs) operating under cGMP Annex 15 requirements

FAQ

Is this a factory-refurbished unit or third-party refurbished?
This unit is professionally refurbished by SpectraLab Scientific, an ISO 17025-accredited service provider specializing in analytical instrumentation. Refurbishment includes OEM-specified component replacement, full functional validation, and traceable calibration—distinct from basic cosmetic reconditioning.
Does the 6-month warranty cover parts and labor globally?
Yes—the warranty covers all parts and labor for defects in materials or workmanship. On-site service is available in North America, EU, and APAC regions via authorized field engineers; remote diagnostics and spare parts dispatch are supported worldwide.
Can the Ultravap be integrated into automated liquid handling workflows?
While not natively robotic-arm compatible, the Ultravap features RS-232 and TTL trigger inputs for external start/stop synchronization with third-party automation platforms (e.g., Hamilton STAR, Tecan Freedom EVO) using custom script integration.
Are consumables such as gas manifolds and O-rings available separately?
Yes—SpectraLab stocks genuine Porvair Sciences consumables, including 96-pin and 24-pin manifolds, PTFE-coated stainless-steel needles, and silicone gasket kits, all with batch-specific CoA documentation.
What documentation accompanies shipment?
Each unit ships with a Refurbishment Certificate, Calibration Report (NIST-traceable temperature and pressure verification), Electrical Safety Test Record, and full user manual in English. Optional GxP documentation packages are available upon request.
