Product Overview	The Small-Dose Automatic Poultry Vaccinator is a reusable veterinary syringe designed for precise and repetitive administration of small vaccine or medication volumes in poultry and other small animals. The reference small-dose syringe uses an adjustable glass-barrel dosing system covering 0.1 cc to 0.5 cc. This makes it suitable for poultry vaccination programs where accurate low-volume dosing and high-throughput operation are required. An automatic draw-off system connects the syringe to an external vaccine container through a plastic hose, allowing repeated injections without manually refilling the barrel after every bird.
Key Features	0.1-0.5 cc Adjustable Dose: Suitable for small-volume poultry vaccination and veterinary treatment. 0.1 cc Adjustment Steps: Provides practical dose selection throughout the specified range. Automatic Refill: Draws vaccine from an external container through a hose as the syringe returns after each injection. Graduated Glass Barrel: Transparent construction allows visual monitoring and confirmation of the selected dose. High-Volume Operation: Designed for fast repetitive treatment of large numbers of birds. Lightweight Ergonomic Design: Supports comfortable handling during extended vaccination sessions. Reusable Components: Valves, seals, springs and barrel components can be inspected and serviced. No External Power Required: Manual operation does not require electricity or compressed air.
Structural Components	Syringe Body: Main structural housing supporting the dosing and injection mechanism. Graduated Glass Cylinder: Transparent barrel for dose setting and visual monitoring. Piston: Displaces the selected volume during each injection. Piston O-Ring: Maintains sealing inside the glass cylinder. Adjusting Screw: Controls the selected injection volume. Adjusting Screw Nut: Locks the selected dose position. Valve Spring and Stainless Ball: Control intake and discharge flow. Luer Lock Needle Adapter: Provides a secure connection for a compatible injection needle. Tubing Valve Housing: Connects the syringe to the vaccine supply hose. Handle and Return Spring: Provide manual injection action and automatic refill return.
Working Principle	The required dose is selected using the adjustment screw and secured in position with the locking nut. A cannula is inserted into the vaccine container and connected to the syringe inlet through a plastic hose. Before vaccination, the syringe is operated several times to prime the liquid path and remove trapped air. When the operator squeezes the handle, the piston moves through the calibrated barrel and delivers the selected dose through the needle. Releasing the handle allows the return spring to reset the mechanism and draw the next dose automatically from the vaccine container.

Applications	The Small-Dose Automatic Poultry Vaccinator is suitable for commercial layer farms, breeder farms, pullet rearing operations, broiler breeder facilities and poultry vaccination service teams. Typical applications include injectable vaccination, preventive veterinary treatment and repetitive small-volume medication delivery. It is suitable for poultry integrators, veterinary teams, livestock equipment distributors, dealers and agricultural project suppliers requiring portable vaccination equipment for commercial farm use.

Installation & Maintenance	Before use, inspect the glass barrel and confirm that threaded connections, valves, washers, springs and seals are correctly installed. Set the required dose using the adjustment mechanism, connect the plastic hose to the vaccine container through the cannula and prime the syringe until liquid flow is stable. After use, flush the syringe with clean water several times to remove vaccine residue. Appropriate components should then be disassembled, cleaned and sterilized according to veterinary hygiene procedures. Periodically inspect the piston O-ring, valve springs, washers, glass barrel and hose connections. Replace worn components when necessary to maintain consistent dosing and automatic refill performance.
Project Cases	Small-dose automatic vaccinators can be included in veterinary equipment packages for breeder farms, layer operations, pullet facilities and poultry vaccination contractors. For large farm projects, the syringe can be supplied with compatible needles, vaccine hoses, cannulas, maintenance components and replacement glass barrels according to project requirements.
