Insulin Pen Needles 4mm – Precision needles for research dosing pens

The 4 mm Insulin Pen Needles are designed for use with refillable pens in research settings. Their short length (4 mm) provides minimal penetration and maximum control, making them ideal for administration in experimental applications such as peptide research, dose measurement, and reproducible administration protocols.

Benefits of Insulin Pen Needles 4mm

• Short length (4mm) allows for less invasive administration and consistent dosing
• Suitable for use with refillable pens – directly compatible
• Reduces potential variability by standardizing length and compatibility
• Easy to use and suitable for repeated administrations within study designs
• Accurate measuring and administration: essential for experiments with peptides and solutions
• Buying insulin pen needles means fewer complications, higher reproducibility and more efficiency

How does the Insulin Pen Needles 4mm work?

You click the needle onto the dosing pen, load the solution into the pen, set the correct dose, and insert the needle into the correct location for the test. The pen needle does exactly what it's intended to do: a stable connection between the pen and the skin or test matrix, allowing you to measure and dose in a controlled manner. Its 4 mm length is ideal for consistency in experimental applications where variation in penetration depth must be kept to a minimum.
