Product Name	Fixed-Dose Automatic Poultry Vaccinator
Product Image
Product Overview	The Fixed-Dose Automatic Poultry Vaccinator is a professional continuous injection tool designed for efficient mass vaccination of chicks, chickens, turkeys and other small birds. Its fixed-dose system uses interchangeable preset pistons, allowing operators to select the required injection volume without repeatedly adjusting a graduated dosage mechanism during vaccination work. The robust all-metal syringe body is suitable for intensive poultry production environments, while the ergonomic pistol-style grip helps reduce operator fatigue during repetitive inoculation procedures. The vaccinator can be connected to a vaccine container through a flexible draw-off tube, allowing automatic refill between injections and supporting efficient batch vaccination in hatcheries, poultry farms and veterinary service operations.
Key Features	Fixed-Dose Operation: Preset pistons provide repeatable injection volumes without frequent dosage adjustment. Automatic Refill: The internal valve system automatically draws the next dose from the connected vaccine container after each injection cycle. All-Metal Construction: Durable metal components eliminate fragile glass barrels and support repeated commercial use. Interchangeable Pistons: Different preset piston sizes allow quick conversion between commonly used poultry vaccination doses. Ergonomic Hand Grip: Pistol-style handle and rear palm support improve control during repetitive vaccination work. Easy Maintenance: Serviceable valves, seals and pistons can be removed for cleaning, inspection and replacement. Commercial Poultry Use: Suitable for hatcheries, layer farms, broiler operations, breeder facilities and large poultry vaccination programs.
Structural Components	Metal Syringe Barrel: Main dosing chamber designed for repeated veterinary vaccination cycles. Fixed-Dose Piston: Determines the injection volume for each operating cycle. Ergonomic Handle: Provides a secure grip and improves control during continuous vaccination. Rear Plunger Handle: Transfers hand movement to the internal piston mechanism. Valve Assembly: Controls vaccine intake and discharge during automatic refill operation. Draw-Off Connector: Connects the syringe to the vaccine supply tube. Needle Connection: Accepts a compatible veterinary injection needle according to the vaccination program. Flexible Supply Tube: Transfers vaccine from the source container to the syringe.
Working Principle	The vaccine supply tube is connected between the vaccinator and the vaccine container. A fixed-volume piston is selected according to the required dose. During each injection cycle, hand pressure moves the piston forward and delivers the preset volume through the needle. When the operating mechanism returns, the valve system draws a fresh dose from the vaccine container into the syringe barrel. The vaccinator is then ready for the next bird without manual syringe refilling. Fixed-dose operation helps maintain a consistent mechanical delivery volume throughout repetitive poultry vaccination procedures.

Installation & Maintenance	Before operation, install the required fixed-dose piston and connect the clean vaccine supply tube to the draw-off fitting. Fit a suitable sterile needle according to the approved vaccination procedure. Prime the vaccinator before starting flock vaccination to ensure the dosing chamber and supply line are properly filled and free from unwanted air. After use, disassemble the serviceable components according to the operating instructions. Thoroughly clean and sterilize reusable parts using procedures compatible with the syringe materials and the veterinary product being administered. Inspect valve springs, valve balls, washers, piston O-rings, tubing and needle connections regularly. Worn sealing components should be replaced to maintain reliable automatic refill and repeatable dosing.
Project Cases	Fixed-dose automatic vaccinators are suitable for poultry operations where large numbers of birds require repeated individual injections using a standardized dose. In commercial hatcheries and intensive poultry production projects, multiple vaccinators can be assigned to trained vaccination personnel to support organized flock processing and reduce interruptions caused by manual syringe refilling. Spare pistons, seals, needles and tubing can also be included in farm veterinary maintenance inventories to support routine vaccination campaigns.
Product FAQ	Q: What makes a fixed-dose poultry vaccinator different from an adjustable syringe? A: The injection volume is determined by a preset piston, reducing the need to repeatedly check or adjust a graduated dose setting during mass vaccination. Q: What reference dose sizes are available? A: The reference configuration includes 0.10 cc, 0.20 cc, 0.25 cc, 0.30 cc and 0.50 cc pistons. Q: Does the vaccinator refill automatically? A: Yes. The valve and draw-off tube system refills the syringe from the connected vaccine source between injection cycles. Q: Is the syringe suitable for one-day-old chicks? A: The reference model is designed for mass treatment of one-day-old chicks and other small birds requiring doses up to 0.50 cc. Q: Can the vaccinator be sterilized? A: Compatible components of the reference all-metal syringe can be sterilized at temperatures up to 125°C. Q: Are replacement parts available? A: Valve springs, valve balls, washers, piston O-rings, pistons, tubing and other compatible service parts can be supplied according to requirements.
