FAQs
Can a mixing syringe also be used for patient injections?
Its 23-gauge needle is wider than the 26G or 27G needles normally chosen for allergy injections, so most clinics reserve mixing syringes for vial preparation and use finer allergy syringe trays for patients. Keeping the two tasks on separate syringes also reduces the chance of cross-contaminating extract vials.
Why use a separate syringe for each extract during mixing?
Using the same syringe to draw different allergens can carry traces of one extract into another vial and change its potency or composition. Using a fresh, sterile syringe for each extract keeps each dilution accurate and traceable. A tray of 25 makes that one-syringe-per-transfer habit easy to keep. It also reduces the risk of a mismeasured dilution.
Is 1 mL enough capacity for mixing?
For allergen immunotherapy, extract transfers are usually small and need precise measurement, so a 1 mL barrel with fine graduations is often the right tool. Larger diluent volumes are typically handled with larger syringes, while the 1 mL mixing syringe handles exact extract amounts. Match the syringe to the volume being transferred.
What does "low dead space" mean for mixing?
Dead space is the fluid left in the hub and needle after you fully depress the plunger. When mixing, retained extract means slightly less than the measured amount reaches the vial. A low dead-space design reduces that gap, improving transfer accuracy and conserving expensive allergen concentrates. For high-value extracts, that small difference adds up quickly across a busy month.
Who is this product intended for?
Sol-Millennium lists licensed healthcare professionals as the intended users. Typical buyers include allergy and immunology practices, hospital clinics, and compounding staff preparing allergen extract sets, and many distributors require business or license documentation before shipping. Ordering through an established medical supply account is usually the simplest route.
