Product Overview	The Dual-Vaccine Automatic Poultry Vaccinator is a professional double-barrel veterinary syringe developed for high-volume poultry vaccination. It allows two different vaccines to be administered at two different fixed dosages during a single operating cycle. The dual-syringe configuration supports one-needle or two-needle vaccination. With a compatible 2-to-1 bridge, both vaccine channels can be directed through a single needle when the vaccination protocol permits. This design helps commercial poultry farms, hatcheries and vaccination crews reduce repeated handling, improve workflow efficiency and maintain consistent dosing during large flock vaccination programs.
Key Features	Dual-Vaccine Delivery: Two independent syringe channels allow two different vaccines to be administered during one vaccination operation. Independent Dosage Selection: Each syringe can use a separate fixed-dose piston according to the required vaccination protocol. Fixed-Dosage Design: Replaceable calibrated pistons help maintain repeatable dose delivery during mass vaccination. One- or Two-Needle Operation: The system can be configured for two separate needles or a compatible 2-to-1 bridge. All-Metal Syringe Structure: Durable construction is designed for intensive veterinary use and repeated cleaning. Automatic Refill Action: Vaccine is drawn through connected hoses as the syringe mechanism resets between injections. High-Volume Poultry Application: Suitable for commercial vaccination programs involving large numbers of birds. Serviceable Components: Pistons, valves, O-rings, springs and related wear components can be maintained or replaced as required.
Structural Components	Double Syringe Bodies: Two parallel vaccination chambers allow independent vaccine handling. Fixed-Dose Pistons: Interchangeable pistons determine the selected dose for each syringe channel. Return Springs: Support automatic syringe reset after each injection cycle. Valve Assemblies: Control vaccine intake and discharge through each barrel. Plastic Supply Hoses: Connect the syringe channels to vaccine containers. Cannula Needles: Used for drawing vaccine from source containers. 2-to-1 Bridge: Combines both vaccine channels into a single needle outlet when required. Handle Assembly: Provides ergonomic control during repetitive poultry vaccination.
Working Principle	Each syringe barrel is connected to its own vaccine source through a dedicated hose and cannula. The operator selects the required fixed-dose piston for each vaccine channel before beginning the vaccination procedure. When the handle is operated, both syringe mechanisms deliver their preset vaccine volumes during the same vaccination cycle. Depending on the selected bridge configuration, the vaccines can be delivered through one needle or through two separate needles. When the handle returns to its starting position, the automatic syringe mechanism refills the chambers for the next bird, supporting continuous repetitive vaccination.
Technical Specifications	Product Type: Double Automatic Poultry Vaccination Syringe Syringe Configuration: Dual barrel Operation: Automatic refill, manual injection Dosage System: Fixed-dose interchangeable pistons Available Reference Dosages: 0.1 cc, 0.2 cc, 0.25 cc, 0.3 cc, 0.5 cc Dosage Selection: Independent for each syringe channel Needle Configuration: One needle or two needles Bridge Configuration: 2-to-1 bridge available Main Construction: All-metal syringe body Vaccine Supply: External container through plastic hose Sterilization: Autoclave-compatible components up to 120°C according to the reference manual Additional Bridge Options: Available upon request
Applications	The Dual-Vaccine Automatic Poultry Vaccinator is suitable for broiler breeders, layer breeders, pullets, replacement stock and other poultry vaccination programs requiring injectable vaccines. It is particularly useful where two injectable vaccines must be administered during the same handling procedure and where reducing repeated bird handling can improve operational efficiency. Typical users include commercial poultry farms, hatcheries, veterinary service teams, integrated poultry companies, vaccination contractors, livestock equipment distributors and agricultural project suppliers.
Customization Options	Dosage piston combination: According to vaccination protocol One-needle configuration: Available upon request Two-needle configuration: Available upon request Alternative bridge configuration: Available upon request Needle specification: According to project requirements Supply hose length: Customizable Spare maintenance kit: Available upon request Poultry vaccination kit configuration: Customizable Bulk commercial supply: According to project requirements
Installation & Maintenance	Before use, select and install the correct fixed-dose pistons for both syringe barrels. Confirm that valve springs, washers, seals and threaded components are correctly positioned and tightened. Connect each plastic hose to the appropriate vaccine source and prime both syringe channels until air is removed and vaccine flow is stable. After vaccination, the syringe should be cleaned and sterilized according to veterinary hygiene procedures. The reference manufacturer recommends sterilization after use, and compatible syringe components can be autoclaved up to 120°C. O-rings, valve components, springs and fiber washers should be inspected periodically and replaced when worn or damaged.
Project Cases	Dual automatic poultry vaccinators are suitable for integration into commercial poultry vaccination kits used by breeder farms, hatchery service teams and large integrated poultry operations. For high-throughput vaccination projects, separate vaccine containers, hoses, spare pistons, needles and maintenance components can be prepared as a complete field kit according to the vaccination schedule and flock size.
Product FAQ	Q: Can the vaccinator administer two different vaccines at once? A: Yes. The double-barrel design allows two different vaccines to be delivered during one operating cycle. Q: Can each vaccine use a different dosage? A: Yes. Each syringe channel can use its own fixed-dose piston. Q: What reference dose sizes are available? A: The reference configuration includes 0.1 cc, 0.2 cc, 0.25 cc, 0.3 cc and 0.5 cc pistons for each syringe. Q: Can two vaccines be given through one needle? A: Yes. A compatible 2-to-1 bridge allows one-needle operation when the vaccination protocol permits. Q: Can the system also use two needles? A: Yes. One- or two-needle configurations can be used according to the selected setup. Q: Is the syringe suitable for repeated commercial use? A: Yes. The all-metal construction and replaceable maintenance components are intended for repeated veterinary vaccination work.
