Buying Guide
What size do I need? For tiny doses, 31G needles at 5/16 inch (8mm) length offer minimal tissue disruption and precise flow. For general injections or transfers, 1 mL/cc syringes with clear graduations improve measurement accuracy and reduce dosing errors.
Should I choose Luer Lock or Luer Slip? If your equipment uses Luer Lock connections, pick needles designed for Luer Lock to prevent detachment. Luer Slip items are compatible with slip-tips but may require extra caps to secure connections.
Is a bulk pack better than individual packaging? Bulk packs are cost-effective for clinics with steady demand, while individually wrapped syringes are convenient for distribution, storage, and controlled usage in home care or mobile settings.
What about sterility and packaging? Ensure packaging indicates sterile handling and sealed packaging. If sterility certifications are critical (e.g., for sensitive injections), confirm the supplier’s sterilization method and expiration details before use.
Are these products versatile for non-medical liquids? Some syringes and needles can be used for inks, glues, or paints in laboratory or hobby contexts. Check chemical compatibility with the liquids you plan to use.
