The volume of fluid in the needle

FAQ

Why is there a sticky substance in my syringe/needle?

If your sample contains protein, it is not recommended to rinse your syringe/needle with an ethanol-based solution as this often creates a sticky residue which is difficult to remove. Please see the care and use guide for additional cleaning recommendations.
Consider 34 needle gauge

FAQ

What do I need to consider when using a 34 gauge needle?

For some applications the smaller size is a real advantage but has inherent complications. 34 gauge tubing requires special cutting tools to ensure the tubing is not crimped shut. Due to this limitation the needles are only available in restricted lengths and point styles. The small inner diameter (ID) results in a needle more prone to clogging, and cleaning wires are not available for this size.

FAQ

Which point style is recommended for animal injections?

Hamilton Point Style 4 at a 12° bevel is recommended for animal injections as the sharpest needle possible is often required. For applications where injection site depth is critical or the target is small, a 30° or 45° bevel is suggested.
