HSW ECO-MATIC Twin Double-Needle Veterinary Syringe

The HSW ECO-MATIC Twin is an automatic self-filling veterinary syringe equipped with two independent barrels and two needles. It is designed to administer two different vaccines or veterinary products simultaneously during a single animal handling procedure.

Its lightweight ergonomic construction, adjustable barrel position and selectable needle spacing make it suitable for efficient vaccination of livestock of different ages and sizes. Each barrel operates independently, allowing different fixed-dose combinations to be used according to the vaccination protocol.

• Twin independent medication barrels
• Dual-needle simultaneous injection configuration
• Adjustable needle spacing system
• Bottle mount or tubing medication supply
• Ergonomic lightweight veterinary handle
• Multiple fixed-dose barrel combinations

• Dual Independent Barrels: Two separate medication circuits allow two different veterinary products to be administered independently.
• Simultaneous Dual Injection: Two needles deliver both products during one injection cycle, reducing animal handling time.
• Automatic Self-Filling: Both barrels automatically refill from connected medicine containers after each injection.
• Adjustable Needle Distance: Needle spacing can be adapted according to animal age, body size and species.
• Adjustable Barrel Position: Barrel orientation can be repositioned for improved operator comfort and handling.
• Flexible Medicine Supply: Compatible with bottle-mounted supply, tubing connection or a combination of both.
• Fixed-Dose Combinations: Multiple barrel capacity combinations are available for different vaccination programs.
• Lightweight Construction: Premium plastic components provide durability while keeping the injector comfortable for repetitive use.
• Luer Lock Needle Connection: Provides secure attachment of compatible veterinary needles.

Two separate medicine supplies are connected to the independent syringe barrels. When the operator squeezes the handle, both plungers move simultaneously and deliver their preset doses through two separate needles.

When the handle returns to its original position, the self-filling mechanism automatically draws the next doses into both barrels. This allows rapid repeated vaccination while keeping the two veterinary products physically separated throughout the dosing process.

• Simultaneous administration of two livestock vaccines
• Pig vaccination programs
• Cattle vaccination and preventive treatment
• Sheep and goat vaccination
• Commercial livestock disease-prevention programs
• Breeding herd vaccination management
• Veterinary clinics and field vaccination services
• High-throughput repetitive animal vaccination

• Inspect both barrels, valves, plungers, medication connections and needle fittings before use.
• Select the required fixed-dose barrel combination according to the vaccination protocol.
• Connect each barrel to its designated medicine bottle or tubing supply.
• Install compatible sterile veterinary needles securely on both Luer Lock fittings.
• Adjust the needle spacing according to animal age, size and species.
• Prime both medication circuits independently and remove trapped air before vaccination.
• Never mix the two medication circuits during assembly, filling or cleaning.
• Flush and clean both barrels and supply lines thoroughly after use.
• Inspect valves, seals, tubing and moving parts regularly and replace worn components when required.
• Store the cleaned and dried injector in a clean, dry and protected environment.

Q: What is the main advantage of the twin-needle syringe?
A: It allows two different veterinary products to be administered simultaneously through two independent barrels and two needles, reducing animal handling time.

Q: Are the two medication circuits independent?
A: Yes. Each barrel has its own medication supply and injection path, allowing two products to remain separated during administration.

Q: What standard 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: Can the needle distance be adjusted?
A: Yes. Seven needle distances are available, ranging from 20 mm to 36 mm, allowing adaptation to different animal sizes and species.

Q: Can the syringe use medicine bottles and tubing?
A: Yes. Each medication circuit can be configured with a bottle mount, tubing connection or a suitable combination according to the vaccination setup.

Q: Is the dose continuously adjustable?
A: No. The HSW ECO-MATIC Twin uses fixed-dose barrel combinations. Select the appropriate barrel configuration for the required vaccination dose.

Q: Is it suitable for commercial livestock farms?
A: Yes. Its automatic self-filling mechanism and simultaneous dual-product injection are designed for efficient repetitive vaccination programs.

Q: Can additional dose combinations be supplied?
A: Yes. Additional combinations including 0.3 ml, 4 ml and 5 ml barrels may be available on request depending on configuration.
