2.4mg is the upper end of the dose window for most GLP-1 analog studies, but if you're titrating down to 0.25mg for a baseline in a rodent model, that same spring mechanism has to hold precision across the entire band — we see this a lot in PK/PD labs where the same device is used for both loading and maintenance doses in a single protocol.
cartridge fit is actually the main constraint here — it's built for standard 1.5mL or 3mL formats, so if your research solution comes in a non-standerd vial or a pre-filled syringe with a different luer interface, you'll need to check dimensional compatibility before ordering (usually specified in the drawing).
It's a spring-type autoinjector, not a gas-powered or electronic unit, which basically means the activation force is consistent and the needle insertion depth is set mechanically — no battery failure risk in cold storage rooms, but the spring does have a shelf life of roughly 18 months form manufacutre before force decay becomes noticeable.
Typical order is 500 units or so for a small lab validation batch, and our company can do MOQ down to 100 if you're just verifying the dose click feedback against your HPLC data. CE and ISO 13485 docs come with every shipment — we usually have stock, but confirm lead time for custom dose labeling if you're running a blinded study.
One thing we don't recommend this for is any oil-based or high-viscosity formulation above about 20 cP because the spring force just isn't enough for consistent injection across the full plunger travel — it'll stall around the 2.3mg mark. Also, for femto-gram level dosing, the mechanicla tolerance of ±5% is probably too coarse, so keep that in mind for ultrashort peptides.
It handles six preset doses from 0.25 mg up to 2.4 mg – so you can use it for low starting doses or full maintenance doses for GLP-1 or insulin research.
Yes, we can share both our CE and ISO13485 certificates. Just ask your sales contact and we'll send them over before you order.
MOQ is typically 500 units for the first order, but if you're just doing a pilot study we can sometimes work out a smaller batch. Just let us know your quantity.
Absolutely – we accept custom labeling, blister tray design, and carton box printing. Send us your artwork or specs and we'll quote the setup cost.
Each unit is packed in a carton box (19x19x161mm) with foam inserts to protect the spring mechanism. We can also add individual blister packs if needed.
