Overview
The Thermo Scientific imPULSE Single-Use Mixer (S.U.M.) is an engineered solution for scalable, aseptic mixing in biopharmaceutical manufacturing and process development. Designed around bottom-driven, single-use agitation technology, the imPULSE system eliminates mechanical seals, shafts, and clean-in-place (CIP) requirements—reducing contamination risk and operational complexity. Its core principle relies on pneumatically actuated rolling diaphragm motion beneath a disposable mixing bag, generating controlled laminar-to-turbulent flow profiles across volumes from 30 L to 5,000 L. This mechanism ensures consistent shear delivery, low particle generation, and high mixing uniformity without direct contact between moving parts and product—making it compliant with current Good Manufacturing Practice (cGMP) environments and suitable for use in ISO Class 5–7 cleanrooms.
Key Features
- Linear scalability across 30 L to 5,000 L working volumes using standardized bag geometries and identical agitation kinematics
- Hexagonal, open-top, sloped-bottom disposable mixing bags with integrated ports for buffer preparation, media formulation, and downstream transfer
- Rolling diaphragm actuation system: provides suction-based disc motion without surface abrasion or particulate shedding—validated per USP and ISO 8573-1 Class 3 air purity standards
- Integrated control panel featuring relay logic, manual push-button interface, selector switches, and real-time digital RPM display
- Dedicated powder handling subsystem with fixed suspension/hoisting frame—compatible with both manual and motorized winch configurations for BPC (Bulk Powder Container) integration
- Jacketed mixing vessel with thermal insulation layer for temperature-controlled processes (e.g., cold-buffer preparation or ambient-sensitive formulations)
- Load-cell-based gravimetric monitoring system with ±0.1% full-scale accuracy for precise mass-based addition and endpoint detection
- Automated gas sparging and venting control module supporting nitrogen purging, CO₂ blanketing, and sterile filtration-compatible exhaust routing
Sample Compatibility & Compliance
The imPULSE S.U.M. supports a broad range of bioprocess-relevant materials including cell culture media, purification buffers, viral vectors, monoclonal antibody formulations, and high-viscosity polymer solutions (up to 50,000 cP). All wetted components—including bag film (USP Class VI-certified ethylene vinyl acetate), diaphragm elastomer (medical-grade silicone), and fluid path tubing—are fully extractables/leachables tested per USP and . The system architecture meets IEC 61000-6-2/6-4 electromagnetic compatibility requirements and is designed to support FDA 21 CFR Part 11-compliant electronic records when paired with validated Thermo Scientific software modules. It conforms to ISO 13485:2016 quality management system requirements for medical device manufacturing and supports audit readiness for EMA Annex 1 and PIC/S GMP Annex 15 validation protocols.
Software & Data Management
The imPULSE platform interfaces with Thermo Scientific’s ProcessLogix™ Suite for configurable recipe management, parameter logging, and electronic batch record (EBR) generation. All critical process parameters—including rotational speed, weight change rate, gas pressure, temperature setpoint deviation, and event timestamps—are captured at ≥1 Hz sampling frequency and stored with cryptographic hash integrity. Audit trails are immutable and time-stamped in accordance with ALCOA+ principles. Optional integration with DeltaV™ DCS or Siemens Desigo CC allows for centralized supervisory control in multi-unit operations. Data export formats include CSV, PDF, and XML for regulatory submission readiness.
Applications
- Buffer and cell culture media preparation under closed-system conditions
- Final drug product formulation (FDP) mixing prior to fill-finish
- High-viscosity blending of polysaccharide-based excipients or lipid nanoparticle suspensions
- High-solids powder dispersion and reconstitution (e.g., lyophilized intermediates)
- Cell pellet resuspension and homogenization post-centrifugation
- Tissue homogenization and lysate clarification in upstream processing
- Harvest collection and hold tank conditioning prior to chromatography
- Cryopreserved cell bank thawing and dilution under controlled thermal ramping
- Downstream purification intermediate pooling with density-matched mixing
FAQ
Is the imPULSE S.U.M. compatible with single-use bioreactor bags from other vendors?
No—the system is validated exclusively with Thermo Scientific-branded disposable bags engineered for dimensional tolerances, film thickness consistency, and diaphragm coupling geometry.
Can the imPULSE operate under inert gas overlay during mixing?
Yes; the integrated gas control module supports programmable N₂ or argon sparging, headspace blanketing, and pressure-regulated venting with HEPA-filtered exhaust.
What level of process validation support is provided?
Thermo Scientific delivers IQ/OQ documentation packages, FAT/SAT protocols, and URS alignment reports—all aligned with ASTM E2500 and ISPE Baseline Guide Vol. 4 frameworks.
Does the system meet requirements for GMP manufacturing of ATMPs?
Yes; design qualification includes ISO 14644-1 Class 5 airflow modeling, particulate monitoring, and end-to-end traceability for Advanced Therapy Medicinal Products (ATMPs) under EMA Regulation (EC) No 1394/2007.
