E-Series Twin-Barrel Veterinary Syringe

The E-Series Twin-Barrel Veterinary Syringe is an automatic self-filling injector designed to administer two different veterinary products simultaneously while keeping the two medication circuits separate.

Its lightweight plastic construction, dual independent barrels and flexible bottle or tubing supply make it suitable for efficient vaccination programs on commercial livestock farms. Multiple fixed-dose combinations are available for different veterinary protocols.

• Two independent medication barrels
• Dual veterinary needle configuration
• Bottle mount and tubing connection options
• Adjustable barrel orientation
• Multiple fixed-dose combinations

• Dual Independent Barrels: Allows two different vaccines or medications to remain separated during administration.
• Simultaneous Injection: Two products can be delivered during one injection cycle to improve working efficiency.
• Automatic Self-Filling: Each barrel automatically draws the next dose from its connected medication source.
• Fixed-Dose Combinations: Available in several paired dose configurations for different vaccination protocols.
• Adjustable Needle Spacing: Needle distance can be adapted to animal age, size and species.
• Flexible Medication Supply: Compatible with bottle mounting, tubing connection or a combination of both.
• Adjustable Barrel Position: Barrel orientation can be changed for operator comfort and different bottle arrangements.
• Luer Lock Connection: Provides secure attachment of compatible veterinary needles.
• Lightweight Design: Durable plastic construction supports repetitive vaccination work with reduced operator fatigue.

Each barrel is connected to a separate veterinary product. When the handle is squeezed, both plungers move simultaneously and deliver their fixed doses through two independent needles. When the handle returns, the self-filling mechanism automatically draws the next dose into each barrel, preparing the syringe for the next animal.

• Simultaneous administration of two vaccines
• Pig vaccination programs
• Cattle vaccination and preventive treatment
• Sheep and goat vaccination
• Breeding herd health management
• Commercial livestock vaccination programs
• Veterinary clinics and field vaccination services

• Inspect both barrels, seals, valves, needle fittings and medication connections before use.
• Connect each barrel to the correct vaccine bottle or tubing supply.
• Install compatible sterile veterinary needles securely onto both Luer Lock fittings.
• Adjust the needle spacing according to animal size, age and species.
• Prime both medication circuits separately and remove trapped air before vaccination.
• Keep the two medication circuits separate during filling, operation and cleaning.
• Clean and flush both barrels and supply connections thoroughly after use.
• Inspect seals, valves and tubing regularly and replace worn components when necessary.
• Store the cleaned and dried syringe in a clean, dry environment.

Q: What is the main function of the twin-barrel syringe?
A: It allows two different veterinary products to be administered simultaneously through two separate barrels and two needles.

Q: Do the two medicines mix inside the syringe?
A: No. The two barrels and medication pathways operate independently to keep the products separated.

Q: What dose combinations are available?
A: Standard combinations include 0.5 + 0.5 ml, 0.5 + 2 ml, 1 + 1 ml, 1 + 2 ml and 2 + 2 ml.

Q: Is the dosage adjustable?
A: The standard product uses fixed-dose barrel combinations. The appropriate combination should be selected before use.

Q: Can the needle spacing be adjusted?
A: Yes. Seven needle distances from 20 mm to 36 mm are available for different animal sizes and species.

Q: Can medicine bottles and tubing both be used?
A: Yes. The syringe supports bottle mounting, tubing connection or a combination of both supply methods.

Q: Is the syringe suitable for large vaccination programs?
A: Yes. Automatic refilling and simultaneous dual-product injection make it suitable for repetitive vaccination on commercial livestock farms.
