Overview
The Biotage TurboVap II is a fully automated, quantitative sample concentration system engineered for precision, reproducibility, and regulatory compliance in high-throughput analytical laboratories. It operates on the principle of controlled nitrogen (or inert gas) stream evaporation—enhanced by Biotage’s proprietary vortex shear airflow technology—to accelerate solvent removal while minimizing analyte loss, oxidation, or thermal degradation. Unlike conventional dry-down methods relying on unregulated gas flow or heated blocks, the TurboVap II integrates real-time endpoint detection via optical or capacitive sensors within standardized 50 mL and 200 mL quantitative concentrator tubes. This enables true volumetric termination: each sample is independently concentrated to a user-defined final volume (e.g., 0.5 mL, 1.0 mL), after which gas flow ceases automatically—eliminating over-concentration, foaming, or bumping. Designed as the second-generation platform in the TurboVap family, it builds upon ISO 17025-aligned architecture and supports GLP/GMP workflows through audit-trail-capable software and hardware interlocks.
Key Features
- Independent per-sample endpoint control: Six positions operate simultaneously, each with dedicated gas flow regulation and optical endpoint detection.
- Vortex shear airflow technology: Patented gas dispersion geometry ensures uniform solvent surface agitation without splashing or tube displacement—critical for volatile or viscous extracts.
- Modular universal platform: Compatible with TurboVap LV (48-position low-volume mode) and TurboVap EH (48-position extraction-to-concentration transfer mode) using shared control firmware and mechanical interfaces.
- Multi-format tube support: Accepts 50 mL and 200 mL quantitative concentrator tubes with integrated end-point sensors; also accommodates 1.5–60 mL conical-bottom vials via interchangeable universal holders.
- 7-inch full-color capacitive touchscreen interface: Enables intuitive method setup, real-time parameter monitoring (temperature, elapsed time, gas pressure), and password-protected user access levels.
- Three operational modes: Time-based concentration, volume-based (quantitative) concentration, or hybrid time–volume dual-triggered termination.
- Gradient gas flow programming: Users define up to six sequential gas flow rates per method step—optimized for initial rapid evaporation followed by gentle finishing at low flow.
Sample Compatibility & Compliance
The TurboVap II handles samples across diverse matrices—including aqueous, organic, acidic, and buffered solutions—without requiring tube-specific calibration. Its universal holder design eliminates floating issues commonly observed with plastic centrifuge tubes in water-bath systems. All quantitative tubes comply with ASTM D7097 (standard practice for solvent evaporation in environmental analysis) and are compatible with EPA Method 505, 525.3, and 8270 applications. The system meets ICH Q2(R2) guidelines for method robustness in pharmaceutical QC labs and supports 21 CFR Part 11 compliance when used with Biotage’s optional ELN-integrated software suite, including electronic signatures, change control logs, and immutable audit trails.
Software & Data Management
Control and data acquisition are managed through Biotage’s TurboVap Control Software v3.x, a Windows-based application supporting method import/export, batch scheduling, and remote status monitoring via Ethernet or USB. Each run generates a timestamped .csv report containing start/stop times, final volumes, temperature profiles, and gas pressure history per position. Raw sensor data is retained for ≥30 days and exportable for LIMS integration. Optional software modules enable SOP-driven operation, instrument qualification templates (IQ/OQ/PQ), and electronic record archiving aligned with ALCOA+ principles.
Applications
The TurboVap II is deployed in regulated and research-intensive environments where quantitative recovery and trace-level analyte integrity are non-negotiable. Key use cases include: residual solvent analysis in API synthesis (ICH Q3C), pesticide residue quantification in food commodities (AOAC 2007.01), pharmaceutical impurity profiling (USP ), forensic toxicology sample prep (SWGTOX standards), environmental PFAS extraction workflows (EPA 1633), clinical biomarker enrichment from plasma/urine, and flavor compound isolation in fragrance R&D. Its ability to process heterogeneous sample sets—e.g., 50 mL EPA-compliant extracts alongside 200 mL AOAC-certified food digests—in a single run reduces cross-method validation burden.
FAQ
Does the TurboVap II require external cooling or exhaust ventilation?
No—its closed-loop gas management system recirculates and filters nitrogen, eliminating need for fume hood installation or chilled water supply.
Can I validate the endpoint detection accuracy across different solvents?
Yes—calibration verification is performed using certified volumetric standards (NIST-traceable pipettes); Biotage provides documented protocols for methanol, acetonitrile, ethyl acetate, and hexane.
Is the system compatible with third-party concentrator tubes?
Only Biotage-certified quantitative tubes with integrated optical sensors are supported for automatic endpoint detection; generic tubes may be used in timer-only mode.
What maintenance intervals are recommended for routine operation?
Gas filter replacement every 6 months; vortex nozzle inspection quarterly; full preventive maintenance annually by Biotage-certified field service engineers.
How does the TurboVap II handle viscous or surfactant-containing samples?
The vortex shear airflow pattern maintains consistent surface renewal even in high-surface-tension or foaming-prone matrices—validated per USP analytical instrument qualification guidelines.
