TOSEI FS-V (Bench-Top Single Head Vial Filler) - Benchtop Vial Bottle Filler
The FS-V features a highly compact body structure and top-tier pharmacopoeia-grade hygienic design, allowing for seamless installation within sterile isolators (such as TOSEI ISO-100), biosafety cabinets (BSCs), or laminar flow hoods. The device integrates a highly sensitive servo peristaltic pump system and a programmable needle lifting and dispensing mechanism, ensuring precise micro-volume filling (accuracy up to ±0.5%) while completely eliminating foaming during dispensing and needle residue issues, fully meeting the stringent requirements of GMP Grade A cleanrooms for particle control and aseptic assurance.
I. High-precision servo metering and anti-drip backflow support 2–20 mL (2R–20R), filling accuracy up to ±0.5%, automatic micro-backflow after injection, eliminating needle dripping and contamination.
II. Programmable bottom-up injection: The needle rises smoothly and synchronously with the liquid level, precisely controlling the shear force and completely eliminating foaming and splashing.
III. Dual operating modes and error-proof sensing provide single manual and automatic cycle modes (up to 10 bottles per cycle), and have a "no bottle, no filling" photoelectric error-proof mechanism.
IV. Pharmacopoeia-grade materials and sterilization-resistant design: The contact surfaces are made of SUS316L and USP Class VI silicone tubing. The body is resistant to VHP vaporized hydrogen peroxide sterilization and IPA wiping, meeting Grade A cleanliness requirements.
V. Computerized Compliance and Validation Support: The industrial-grade PLC touch interface supports multiple formulation management, complies with FDA 21 CFR Part 11 and GAMP 5, and provides complete IQ/OQ validation documentation.

Equipment Introduction
High-Precision Servo Peristaltic Dosing System
It adopts a high-performance servo-driven precision peristaltic pump, with a filling accuracy of up to ±0.5% (based on 1 mL of water for injection WFI), ensuring high consistency between micro-volume and expensive drug solutions.
Designed specifically for 2–20 mL (2R–20R) standard vials, the flow path features a disposable/single-use tubing configuration, completely eliminating the risk of cross-contamination and significantly simplifying the cleaning and confirmation process.
Intelligent Bottom-Up Diving Nozzle & Suck-Back Anti-Drip Mechanism
During the filling process, the injection needle can move synchronously up and down with the liquid level, effectively suppressing foaming and droplet splashing in prescriptions containing high-protein, antibody, or surfactant ingredients.
It features a precise micro-suck-back function that instantly cuts off the liquid column and eliminates any drips upon completion of the injection, ensuring a clean sealing surface at the vial neck and preventing any impact on the quality of subsequent capping and sealing.
Flexible Dual-Mode Operation & Container Detection
It supports both "single manual mode" and "single automatic cycle mode" (up to 10 bottles can be filled continuously per cycle), taking into account the flexibility of small-batch R&D and the needs of semi-automatic continuous production.
It comes standard with a high-sensitivity photocapacitor detection system and features a "No Vial, No Fill" safety interlock mechanism to prevent accidental triggering that could lead to waste of the medication or contamination of the machine.
Pharmacopeia-grade sanitary materials are highly compatible with sterile environments.
All pharmaceutical contact parts comply with SUS316L, pharmaceutical grade silicone rubber, UHPE and PTFE standards, and are fully compliant with USP Class VI specifications.
The structure and appearance feature a hygienic design with no blind spots, fully resistant to VHP (vaporized hydrogen peroxide) sterilization and high-concentration IPA wiping; the compact body (L483 × W810 × H675 mm) can be directly integrated into ISO-100 (Grade A) isolators, biosafety cabinets (BSC) or clean benches for operation.
Industrial-grade control systems and regulatory compliance architecture (Industrial PLC Control & Data Integrity Compliance)
The control core complies with IEC 61131-3 and PLCopen international program standards, and is stable, reliable, and easy to maintain.
The computerized system complies with FDA 21 CFR Part 11, GAMP 5 and ALCOA+ data integrity requirements, and supports complete formula management and multi-level access control.
The manufacturer provides a complete suite of DQ, IQ, and OQ verification documentation and PQ on-site technical support.
