Insulin syringes, 0.5 ml (BD Micro-Fine)

The 0.5 ml syringe has a smaller capacity than the 1 ml version, meaning that the graduations are spaced further apart, allowing small volumes to be read even more accurately.

Why use a finer nozzle?

With small volumes, a finer scale improves reading accuracy: each mark represents a smaller quantity. The fine 30G needle is also thin, making it easy to pierce a vial cap. This extra precision is valuable when reconstituting research peptides, where the exact volume determines the concentration.

This information describes the technical background of the device within a laboratory context.

The designation U-100 means that the scale is calibrated to a standard concentration. On the 0.5 ml version, the graduations are spaced further apart than on the 1 ml version, making it easier to read small volumes accurately. The 30G needle is fine, which makes puncturing smooth and protects the rubber stopper. Choosing the right instrument is therefore an underestimated but essential part of accurate laboratory work; with small volumes, that choice carries even greater weight.

Accurate, standardised equipment is essential for reproducible research. The 0.5 ml syringe is designed for situations where reading accuracy with small volumes is crucial.

• Point to note: extra-fine scale for small volumes.
• Point to note: thin 30G × 8 mm needle.
• Point to note: sterility to ensure a clean working environment.

Role in the laboratory workflow

Choose the 0.5 ml syringe when accuracy is essential for small volumes, and the 1 ml version for larger quantities. Both are part of a careful, traceable reconstitution workflow for research peptides.

Standardisation is the key to reproducible results. For small volumes, reading accuracy is the decisive factor, and this is precisely where the 0.5 ml syringe offers an advantage. By consistently using the same syringe, you eliminate a source of variation.

A consistent procedure — clean cap, fixed syringe, controlled volume — together forms the basis of a traceable reconstitution.

The storage and safe disposal of sharp objects are also part of a responsible working practice; a sharps container is essential for this. This ensures that not only the research, but also the surrounding area, remains safe and tidy.

Use the 0.5 ml insulin syringe exclusively for measuring and transferring liquid when reconstituting research peptides in the lab. Follow these steps.

1. 1Remove a new, sterile syringe from its packaging.
2. 2Disinfect the vial cap beforehand using an alcohol wipe.
3. 3Measure out the required volume of bacteriostatic water using the fine scale.
4. 4Gently add the liquid to the vial containing the powder.
5. 5Use each syringe only once and dispose of used needles safely in a needle container.

Working Safely

These syringes are for single use only. Do not reuse them or share them. Always dispose of sharp objects in a suitable needle container.

Practical tip

Read the volume at eye level to avoid parallax errors, and gently tap any air bubbles upwards before taking a reading. With small volumes, even a slight difference in the reading can make a noticeable difference to the concentration. Work calmly and with concentration; rushing is the main cause of reading errors.

Keep the insulin syringes clean, dry and in their original, sterile packaging until use.

Practical storage tips

• Store at room temperature, in a dry, dust-free place.
• Keep the sterile packaging sealed until ready for use.
• Do not use a syringe if the packaging is damaged or has been opened.
• Keep out of reach of children.

Storing the product in a clean, dry place in its sealed packaging ensures it remains sterile until you use the syringe.

Before use, check that the sterile packaging is intact; if in doubt, use a new syringe. Also, store the packaging in an upright and stable position to prevent any damage.
