24/410 28/410 0.6-0.1cc Doses Clamp and Push Lock Hand-operated Flow and Spray Cleaner Trigger Sprayer

Excellent focus! The neck finish size (24mm or 28mm) is one of the most critical specs when sourcing a mini trigger sprayer. It determines which bottle the sprayer will fit.

Let's break down the 24mm vs. 28mm mini trigger sprayer landscape.

Critical Compatibility Checklist Before Ordering

1. [Match the Threads] Verify your bottle's neck finish code. It MUST be 24/410 or 28/410.

2. [Test Output] Order samples to confirm the spray volume (e.g., 0.06cc) is correct for your product. Weigh the spray.

3. [Check Viscosity] Mini sprayers are for low-viscosity, water-like to slightly oily liquids. They cannot pump thick lotions or creams.

4. [Chemical Compatibility] Ensure the pump's internal materials (gasket, valve) are compatible with your formula (alcohol, oils, acids, etc.).

5. [Consider Ergonomics] A 24mm sprayer on a tall 100ml bottle might feel tippy. A 28mm sprayer on a tiny 30ml bottle might look oversized.

   In summary:

   • 24mm is the go-to for ultra-precise, micro-dosing, and super-compact applications.

   • 28mm offers a bit more versatility for mainstream travel-size and personal care products.

   Always order physical samples to test fit, function, and feel before committing to a large purchase.
