It’s a glass prefilled syringe with a fixed injection dose, availble in either 1ml or 2.25ml capacity, and the closure is a press cap — our company can also customize the color and add a printed label if you need branding or batch tracking on the barrel.
We run HPLC for purity and content uniformity, and the COA will show you residual solvent levels are typically under 50 ppm, which matters for sensitive biological assays or when you’re dosing compounds like retatrutide in a clinical setting.
Most buyers in pharmaceutical development or veterinary medicine go with the 2.25ml version because of that it gives them more flexibility for larger volumes, but the 1ml is easier to handle for fixed-dose subcutaneous injections.
Actually, what it does is eliminate the need to draw from a vial, so you get consistent dilevery every time, and the glass material means you won’t have leachables like you might with some plastic syringes.
We usually have stock on the plain glass units, but custom colors or labels add about 20 days or so to lead time, and the MOQ is 5,000 pieces for any customiztion — just confirm the retest policy when you place the order since our company offer a 12-month shelf life from manufacutre.
It’s not suited for multi-dose vials or high-viscosity oils above 200 cP, but for most aqueous formulations or peptides, it’s better than reagent-grade syringes for consistency.
We typically start at 10,000 units per size for standard orders, but we can discuss lower quantities for clinical trial partners. Just reach out with your estimated volume.
Yes, we supply full batch certificates of analysis and can share our ISO and GMP documentation upon request. All syringes are manufactured under strict quality controls.
Absolutely, we offer customized color and printed labels to match your branding or study requirements. The glass material is standard but can be tailored for different fill volumes.
For customized runs, lead time is usually 4-6 weeks after sample approval, depending on order size and label complexity. We can expedite for urgent clinical trials.
They come in sterile blister packs inside sealed cartons, with temperature-controlled shipping available if needed. Standard storage is at room temperature, away from direct sunlight.
