These insulin syringes are sterile, single-use syringes with a permanently fixed fine needle, an orange needle cap and a U-100 unit scale, supplied 500 per pack. They are available in 0.3ml, 0.5ml and 1ml barrel sizes with 29G, 30G or 31G needles in 6mm, 8mm or 13mm lengths. Every syringe is individually sealed and the pack is marked sterile, non-toxic and non-pyrogenic, with CE 0197 and ISO 13485:2016 markings.
U-100 insulin syringes are used to draw up and give small, accurately measured doses under the skin. This bulk pack suits veterinary clinics, animal hospitals, pet owners managing diabetic dogs and cats under veterinary direction, and laboratories that need a fine, low-volume dosing syringe.
Key Benefits of These Disposable Insulin Syringes
- Three barrel sizes: 0.3ml (30 units), 0.5ml (50 units) and 1ml (100 units), so the scale matches the dose.
- Fine needles: 29G, 30G and 31G options for small-volume injections.
- Fixed needle: The needle is built into the syringe, with no separate needle to attach.
- Clear U-100 scale: Bold markings on a transparent barrel for easy reading.
- Individually sealed: Each syringe comes in its own peel-open pack.
- Bulk value: 500 syringes per pack for busy clinics and regular dosing.
Features of the U-100 Insulin Syringe With Fixed Needle
Surgical Steel Needle With Orange Cap
The needle is made from surgical steel and is protected by an orange cap until use. A second orange cap covers the plunger end.
Transparent Barrel With Clear Markings
The see-through barrel carries a printed U-100 unit scale, so the dose and any air bubbles are easy to see. The barrel is printed “For single use” and “U-100 insulin”.
Smooth Plunger and Low-Waste Design
The plunger moves smoothly for steady, controlled dosing. An anti-pull-off plunger stop helps prevent the plunger coming out of the barrel and helps reduce wasted medication.
Wide Finger Flanges
Large flanges give a secure grip and better control during drawing up and injection.

Frequently Asked Questions
What sizes do these insulin syringes come in?
They come in 0.3ml, 0.5ml and 1ml barrels with 29G, 30G or 31G needles in 6mm, 8mm or 13mm lengths. There are nine size options to choose from.
How many insulin syringes are in a pack?
Each pack contains 500 syringes in one size, and every syringe is individually sealed.
Are these U-100 or U-40 insulin syringes?
They are U-100 syringes. Use them only with U-100 insulin. Some veterinary insulins are U-40 and need a U-40 syringe, so check the insulin label first.
How many units does each syringe hold?
The 0.3ml syringe holds 30 units, the 0.5ml syringe holds 50 units and the 1ml syringe holds 100 units of U-100 insulin.
Which syringe size should I choose?
Choose the smallest barrel that holds the full dose. Smaller barrels have wider spacing between unit marks, which makes small doses easier to read.
Are the insulin syringes sterile?
Yes. The pack is marked sterile, non-toxic and non-pyrogenic. Each syringe stays sterile while its individual pack is sealed and undamaged.
Can the needle be removed or changed?
No. The needle is permanently fixed to the syringe. For separate needles, choose Luer-hub hypodermic needles and a Luer syringe.
Can insulin syringes be reused?
No. These are single-use syringes. Dispose of each one in a sharps container after one injection.
