Vented Spike & Fill Tube for Contrast Media
SKU: XY-CFA | Punzón Ventilado y Tubo de Llenado para Medio de Contraste
The two parts at the container end. The vented spike pierces the bottle and admits air as fluid leaves, so a rigid bottle does not collapse and flow does not stall part-way through the draw; the air filter sits in the spike itself. The J fill tube is a moulded curve that reaches the base corner of the container, which is where the last few millilitres pool once the bottle is tilted — on a contrast agent billed by the millilitre, that residue is the reason the part exists. Both are supplied as filling accessories for CT, MRI and DSA injectors.

- Recovering residual volume from the container (J tube)
- Routine consumable replenishment for imaging departments
Frequently Asked Questions — Vented Spike & Fill Tube for Contrast Media
When do I need a vented spike rather than a plain one?
Whenever the container is rigid. A glass or hard plastic bottle does not collapse as fluid leaves, so without a vent a vacuum forms and the draw stalls part-way. Collapsible bags do not need one.
Does the J fill tube really recover more contrast?
It reaches the base corner rather than sitting straight in the middle, which is where residue pools once the bottle is tilted. On a contrast agent billed by the millilitre, that residue is precisely why the part exists.
Can these be ordered together with the syringes and tubing?
Yes, and that is the usual pattern — most orders in this category combine syringes, tubing and filling accessories on a single reference. Send the injector models and estimated monthly consumption and we quote the set.

Full Description — Vented Spike & Fill Tube for Contrast Media
When the vent matters
Whenever the container is rigid. A glass or hard plastic bottle does not collapse as fluid leaves it, so without a vent a vacuum forms and the draw stalls part-way. Collapsible bags do not need one, and fitting a vented spike to a bag buys nothing. The air filter in the spike is what makes venting acceptable — air enters, particulate does not.
Why the fill tube is bent
A straight tube sits in the middle of the bottle. Tilt the bottle to get the last of the contrast and the residue pools in the base corner, which is exactly where a straight tube is not. The J curve reaches it. On an agent priced by the millilitre across a full day's list, that difference pays for the part several times over.
Ordering these with the rest of the line
Most orders in this category combine syringes, tubing and filling accessories on one reference. Send the injector models and estimated monthly consumption and we quote the set together.
