About our luer lock syringes
ThePeptideKit's insulin syringe catalog covers gauges 30G and 31G PRO with 0.5ml U-100 barrels. Every syringe is individually wrapped, sterile, single-use, and CE-marked Class IIa.
Choosing the right gauge
Insulin syringes use U-100 markings and an integrated needle, giving you maximum dose precision in small volumes. 30G is the most widely used standard. 31G PRO — our flagship line — offers the thinnest needle available in 6mm length for minimum discomfort.
Pack sizes and pricing
Our insulin syringes come in 10-pack, 30-pack, and 100-pack quantities. The 100-pack offers the best per-unit price for established workflows; the 10-pack is ideal for first-time orders or evaluation. All packs ship in tamper-evident outer packaging.
Compatibility and certifications
All syringes are manufactured in ISO 13485-certified facilities and CE-marked Class IIa. CE certificates and certificates of analysis are available on request for institutional buyers.
