Frequently Asked Questions
What is the difference between U40 and U100 syringes?
▼
The U40 designation refers to the calibration of the scale on the barrel. These syringes are specifically designed to be used with liquids that have a concentration of 40 units per millilitre. Using them with liquids of a different concentration will lead to an incorrect volume being delivered, so it is essential to match the syringe scale to the specific concentration of your solution.
Why do these syringes have "fixed needles"?
▼
A fixed needle is permanently attached to the syringe barrel, which eliminates dead space - the tiny gap where fluid often gets trapped in removable needles. This design ensures highly accurate delivery of low-volume doses, minimises wasted liquid, and provides a smoother, more stable experience during use as there is no risk of the needle becoming detached.
What size syringe should I choose for my pet?
▼
Choosing the right size depends on the dose prescribed by your vet: - 0.3ml Syringes are best for very small doses, up to 12 units, often used for cats or small dogs.- 0.5ml Syringes are ideal for medium doses, up to 20 units.- 1.0ml Syringes are used for larger doses, up to 40 units. Always select a syringe size that is large enough for the full dose but small enough that you can easily read the graduation marks for accuracy.
