Appliteh AppliAsep Sterile Sampling System

Overview

The Appliteh AppliAsep Sterile Sampling System is an engineered solution for aseptic sampling from stainless-steel bioreactors and process vessels in biopharmaceutical manufacturing and cell culture operations. Designed around the principle of single-point sterile connection with multi-sample capability, the system eliminates repeated vessel penetrations and minimizes exposure to non-sterile environments. It operates on a closed-system architecture compliant with current Good Manufacturing Practice (cGMP) and ISO 13408-1 standards for aseptic processing. Unlike traditional sampling valves or septum-based methods, AppliAsep integrates pre-assembled, gamma-irradiated, single-use fluid paths—ensuring sterility assurance without reliance on in-line steam sterilization (SIP) or cleaning-in-place (CIP) validation for the disposable components. The system maintains full containment throughout upstream and downstream bioprocessing stages, including seed train expansion, fermentation, and storage at ultra-low temperatures (–80 °C), supporting both liquid and frozen intermediate sampling.

Key Features

• Pre-sterilized, fully closed, single-use sampling manifold with integrated aseptic needle and tubing assembly
• Reusable base station with dual anti-slip grooves for secure mounting on standard 1/2″–1″ sanitary port configurations (e.g., Tri-Clamp®, SMS, DIN)
• Fail-safe rotational indexing mechanism: two defined positions—“Standby” (locked, non-actuated) and “Sampling” (engaged, pressure-actuated)—with tactile feedback and visual alignment markers
• Modular design supporting custom bag volumes (1 mL to 500 mL), material compatibility (USP Class VI-certified TPE, COP, or ETFE tubing), and port-specific interface adapters
• No external utility connections required during operation; no SIP/CIP dependency for disposable elements—reducing validation burden and operational downtime
• Compatible with automated process control systems via optional digital position sensor integration (0–10 V or 4–20 mA output)

Sample Compatibility & Compliance

The AppliAsep system supports sampling of mammalian and microbial cell cultures, viral vectors, monoclonal antibodies, plasmid DNA, and other sensitive biologics across temperature ranges from –80 °C to +40 °C. All wetted materials comply with USP and cytotoxicity and systemic injection testing requirements. The system meets ISO 13408-1:2011 for aseptic processing, aligns with FDA guidance on Process Validation (Stage 3: Continued Process Verification), and supports audit readiness for Annex 1 (2022 revision) requirements on contamination control strategy (CCS). Documentation packages include Device Master Record (DMR), Design History File (DHF), and Certificate of Conformance (CoC) per batch.

Software & Data Management

While the core AppliAsep hardware operates mechanically, optional digital add-ons enable traceability integration into MES/SCADA environments. An optional rotary position sensor logs actuation timestamps, operator ID (via RFID badge reader), and sampling event metadata. Audit trails comply with 21 CFR Part 11 requirements when deployed with validated electronic record systems. Raw sampling data—including time-stamped event logs, environmental monitoring correlations (e.g., cleanroom particle counts), and associated batch records—can be exported in CSV or ASTM E2500-compliant XML format for LIMS ingestion.

Applications

• Aseptic withdrawal for bioburden, sterility, and endotoxin testing per USP , , and
• In-process monitoring of metabolites (e.g., glucose, lactate, ammonium), pH, osmolality, and viable cell density
• Particulate analysis (USP ) using filtered sample bags compatible with light obscuration or membrane microscopy workflows
• Mechanical integrity verification: pull-force testing of bag welds, suspension stability assessment under agitation, and freeze-thaw cycle validation
• Long-term stability studies requiring cryogenic sampling from vapor-phase LN₂ tanks or ultra-low temperature freezers

FAQ

Is the AppliAsep system suitable for use with single-use bioreactors?
Yes—AppliAsep interfaces with common single-use bag ports (e.g., Sartorius BPS, Thermo Fisher HyPerforma) via configurable adapter kits.
Can the reusable base be autoclaved?
No—the base is designed for CIP/SIP compatibility only; repeated autoclaving may compromise mechanical tolerances and surface finish integrity.
What is the maximum allowable system pressure during sampling?
Rated for continuous operation up to 2.5 bar(g); transient peaks up to 4.0 bar(g) are permissible for ≤30 seconds per event.
Does AppliAsep support regulatory submission documentation?
Yes—App-liteh provides GxP-aligned validation support documents, including IQ/OQ protocols, risk assessments (FMEA), and change control history upon request.
How is sample volume accuracy verified?
Each lot of pre-assembled sampling sets undergoes gravimetric calibration per ISO/IEC 17025-accredited procedures; certificates of calibration are supplied with shipment.
