Filling and capping machines are the upstream partner to every freeze dryer. In a typical vial fill-finish process the liquid is dosed, half-stoppered, lyophilized, and then aluminum-capped — and SJ Scientific builds the equipment for each step. As a freeze dryer manufacturer since 2012, we match the right filling technology to your product: tool-free peristaltic pumps for fast changeover and single-use aseptic filling, or valveless ceramic piston pumps for high-precision, corrosion-resistant dosing. Models range from benchtop 2–10 ml units to inline systems running up to 300 vials/min, all built to GMP with 316L product-contact parts. Lower-throughput lines can integrate capping into the filler; higher-throughput lines pair a filling-stoppering machine with a dedicated capper.
The SJ-FC-12 is an inline filling (and optional capping) machine built around servo-driven peristaltic pumps. Because the only product-contact part is the silicone tube, changeover is fast and contamination-free — ideal for single-use aseptic filling and frequent product changes.
The SJ-FC-12J is an inline filling-and-stoppering machine built for the volume production of water-for-injection products in medium-to-large pharma plants. Quick-release ceramic plunger pumps with one-pump-per-head servo control deliver accurate, low-shear, corrosion-resistant dosing across a wide 2–500 ml range.
The SJ GJ-G is purpose-built for the filling and stoppering (half- or full-stopper) of injectables and freeze-dried preparations in vials — the exact step that feeds your lyophilizer. A one-head-one-pump servo system meets the high-precision requirements of small-dose filling, while the soft-vacuum stoppering device and progressive top-stopper mechanism sharply raise stoppering success and fully meet GMP.
The SJ-XJ-1200 is a compact, integrated filling-and-capping machine for precise small-volume dosing. Its highly clean, corrosion-resistant valveless ceramic pump delivers ±0.5% accuracy across 2–10 ml — ideal for labs, research institutes, IVD, pharma, hospitals and cosmetics.
