We're seeing a lot of interest in these fixed-dose glass syringes lately, and we've been shippng them for about a year now — they're basically a prefilled syringe with a press cap, so no assembly needed on your end. 2. Most buyers use them for research peptides or nutraceuticals, but they're also pretty common in cosmetics and veterinary settings. 3. The 1ml and 2.25ml capacities are teh two we keep in stock, and the glass body gives a tighter tolerance than plastic for viscous formulations. 4. Actually, buyers typically ask about bulk pricing first, and we can do a discount at 500 units or so — lead time is usually 20-25 days for custom colors or labels, but our company have standard clear ones ready to go. 5. One thing we've noticed is that the fixed dose design isn't great for multi-use vials, but for single-dose applicaions it's pretty much perfect. 6. We own the patent on the closure mechanism, which means we can adjust the needle gauge or label without extra fees.



We offer 1ml and 2.25ml options to fit different dosing needs.
The fixed dose is pre-set during manufacturing, so it delivers the same volume every time. We can customize the dose amount for your order.
MOQ depends on the customization level. For standard specs, we usually start at 10,000 units, but let us know your target and we'll work with it.
Yes, we have self-owned IP and can share ISO certificates, material test reports, and batch records upon request.
For printed labels and custom color, expect around 25-35 days from order confirmation. Standard orders ship faster.
