## Description

This 29G × 0.5 mL insulin syringe is the smaller partner to our 31G × 1 mL model. Its half-millilitre barrel is marked every 0.01 mL (50 units on the U-100 scale), the 29-gauge, 1/2 inch (12.7 mm) needle is fixed, and the plunger has low dead space. As the same graduations cover only half the volume, the marks sit further apart and are easier to read when you measure very small amounts.

Researchers pick it for moving small quantities of dissolved peptide — for instance, dividing a stock vial into measured portions in sterile empty vials, or preparing dilution series for assays. A 29G needle is slightly thicker than a 31G one, so it bends less and lets thick or concentrated liquids pass more easily, and at half an inch long it comfortably reaches the base of a 3 mL vial.

## Frequently asked questions

### What does “29G × 0.5 mL” mean?

29G tells you the gauge of the needle — about 0.33 mm outside diameter — and 0.5 mL is how much the barrel holds. The built-in needle is 1/2 in (12.7 mm) long. Markings go in steps of 0.01 mL, each worth one unit on the U-100 insulin scale, with 50 units in total.

### When is this better than the 31G × 1 mL syringe?

Go for the half-millilitre version when you need small, exact transfers — dividing stock into portions, making dilution series or filling assay wells — since its widely spaced markings are easier to read, or when concentrated liquids flow better through a slightly wider needle. To draw up more than half a millilitre of diluent, use the 1 mL syringe.

### Are the syringes sterile and single-use?

Yes. Each is sterilised, packed on its own and capped on both needle and plunger. Use a new one for every entry into a vial and drop used syringes straight into a sharps container.

### Which quantities are available?

A pack of 10 for occasional use, or a box of 100 for labs that portion and dilute routinely. The 31G × 1 mL syringe is sold separately, in packs of 10 or 50 and in boxes of 100.

### Can the needle be detached or swapped?

No. It is built into the barrel, which is how the syringe keeps its dead space so low. If a procedure needs a detachable needle, use a luer-lock syringe with separate needles instead.
