FAQs
Why choose Luer Lock for pre-filled 1 mL doses?
Pre-filled syringes are often capped and moved between preparation and administration. A threaded tip keeps the cap or needle secure during handling, so you don't lose or contaminate the dose. Slip tips connect faster but are less secure during transport. That security matters most for costly doses.
What does "PP" mean in the product name?
The sources reviewed do not define it. It commonly indicates polypropylene, the plastic typically used for syringe barrels. If your documentation needs the exact material specification, confirm it with Sol-Millennium. Ask for a spec sheet if needed. Material data can also help with chemical compatibility checks.
What happens to unused syringes once the tray is opened?
Once the tray seal is broken, the remaining syringes are no longer protected by the sterile barrier. Size openings to a filling session and follow your pharmacy's aseptic policy for leftovers rather than resealing the tray for later use. Discard any unit that may have been touched or contaminated.
How do I read very small doses on a 1 mL syringe?
Hold the syringe at eye level, expel air bubbles, and align the leading edge of the plunger seal, nearest the tip, with the dose mark. Fine graduations help, but a second check before capping catches most errors. Label each syringe as you go. Never leave prepared doses unlabeled.
How many trays are in a case?
Each case holds 1,000 syringes in 40 trays of 25. Track daily 1 mL usage in trays, multiply by your reorder lead time, and add a buffer for seasonal spikes such as flu or school vaccination periods. Review usage each quarter. Bulk cases lower the per-unit cost.
