About Shown: reusable ring-handle aspirating syringe with harpoon plunger
A dental syringe holds a cartridge of local anaesthetic and a needle for injection. The syringe shown is reusable and aspirating. The harpoon on the plunger engages the cartridge's rubber stopper, so drawing back on the thumb ring pulls the stopper back and lets you check the needle position before injecting.
Choose three things
- Cartridge size: 1.8 ml or 2.2 ml. The syringe must match the cartridges you use, because the chamber is sized for one or the other.
- Needle thread: American or European. Needle hubs are threaded differently by market, so choose the thread that matches the needles you buy.
- Model: the ring-handle aspirating syringe shown, or the Aspira-Plus and other listed models by product code.
Reading the option labels
The options on this page are short catalogue references, not full specifications. Several references share the same size label, and that label does not tell you the cartridge size, needle thread or model, so you cannot choose a syringe from it. Send the reference with the cartridge size and needle thread you need. We confirm the model, cartridge size and thread for that reference in your quotation.
If you are replacing syringes, send the cartridge size and the needle brand you use, and we confirm the matching model.
What is supplied
The syringe is supplied without needles or cartridges. Your quotation lists what is included with each model.
Ordering
- Choose by product code and state the cartridge size and needle thread you need. Both are confirmed for that code in your quotation.
- Evaluation samples of 1–3 pieces per pattern are available, so you can check fit with your own cartridges and needles.
Care
Clean the chamber, harpoon and thread after each use. Check that the harpoon is sharp and the thumb ring moves smoothly. Follow the supplied processing instructions and your facility's validated protocol.
For other instruments used at the chair, see our three-piece examination kit and sterilization cassette.
