You're probably wondering about needle safety first, and honestly that's smart because the permanently hidden needle with that passive locking cover is one of the first things buyers notice when they handle it — it clicks into place and there's no way to accidentally poke yourself after use, which matters a lot in busy clinic settings where sharps disposal can be a headache.
The 1ml and 2.25ml capacty options mean you're covered whether you're filling for weekly GLP-1 doses or something that needs a bit more volume, and we usually see most buyers go with the 2.25ml for treatments like semaglutide since it holds roughly 4 weeks' worth at standerd dosing. But the 1ml version is easier to fit in a pocket or travel bag, so it depends on your end user's routine.
Injection depth is set at 6±2mm and that's actually a pretty tight tolerance for a disposable device — we've tested it with glass and polymer prefilled syringes both, and it consistently hits that sub-Q zone without going too deep or too shallow, which is critical for insulin absorption rates in diabetes care.
Now, about feedback system — you get both a visual click and an audible one, so even if someone's in a noisy room or has limited vision, they know the dose is delivered. The viscosity limit of 20cP covers most GLP-1 formulations we've seen, but obviously if you're working with something thicker like certain biologics, you'd want to check compatibility first because it's not suited for every compound.
Lead time is usually 20 days or so for the 1ml version, maybe 25 for the 2.25ml since we do larger batches on those. We keep COAs on hand from HPLC testing, but I'd suggest confirming your specific needle gauge preference — 27G or 29GTW — because that affects the injection speed slightly and some buyers prefer the finer 29G for less sensation.
One thing buyers don't always think to ask is that the device dimnesions are 18*18*145mm for the 1ml and just a bit taller at 159.2mm for the 2.25ml, so if you're designing packging or a carrying case, that 14mm difference matters more than you'd expect. Anyway, we usually have stock on both, but confirm MOQ for the 2.25ml as it can vary.
Our MOQ for the HL002 starts at 10,000 units per order, and it applies to both the 1ml and 2.25ml capacity options. If you need a mix of both, we can discuss that during your inquiry.
Yes, we can supply material certifications and biocompatibility test reports for the medical-grade plastic. Just let us know what specific standards you need, like ISO 10993, and we’ll include them with your order.
Lead time is usually 30-45 days from order confirmation and deposit, depending on current production schedule. We can expedite for urgent orders if you contact us ahead of time.
Yes, the device can accommodate smaller needle sizes down to 31G if needed. Just specify your preferred gauge when placing the order, and we’ll adjust the assembly accordingly.
Store it in a cool, dry place between 15-25°C, away from direct sunlight. The shelf life is typically 2 years from the date of manufacture when stored properly.
