Ever bought a lotion pump that just didn’t fit your bottle? Or one that squirts out way too much or too little product every time? Most of these mistakes happen because we skip checking the specs. You don’t need to be an expert to choose the right pump. 你只需要知道呢啲數字係咩意思, and you’ll be able to find a perfect match next time you buy 化妝水泵.
Start with Closure Size
The first thing to check for is your bottle’s neck size, each bottle has its own size.This tells you exactly what pump will screw on properly.
The first number, 24, 28. This is the neck diameter in millimeters. So a 24/410 bottle has a neck that’s 24mm wide, if you buy a pump that’s 28mm, it’ll be too big and won’t seal.
The second number,410, 400. This is the closure style. Imagine it like a puzzle: 410 closures are a little taller than 400, so a 24/410 pump won’t fit a 24/400 bottle, even if the diameter is the same.
Get the Right Dosage
Lotion pumps list dosage as a number like 0.5cc, 1.0抄送, or 2.0cc. This is just how much product squirts out with one press. You don’t need to calculate anything just think about how you use the product.
0.5抄送: Great for thick products like hand cream, face moisturizer, or hair serum. A samll dosage goes a long way, so you won’t waste product.
1.0抄送: Perfect for everyday lotions or liquid soap. It’s the most common size because it gives just enough for one use.
2.0抄送: Best for big bottles of thin products, like body wash or conditioner. If you have a family-sized bottle, this size saves you from pressing the pump multiple times.
Measure the Tube
The tube is the long plastic tube that hangs down inside the bottle, if it’s too short, it won’t reach the bottom. 如果太長, it’ll curl up and not work.
Measure your bottle, use a ruler to measure from the top of the bottle’s neck down to the bottom of the bottle. Write that number down.
Check the pump’s dip tube length: most pumps list the dip tube length. Pick one that’s the same than your bottle’s height.
Cut it if needed: If you can’t find the exact length, buy a longer tube and cut it with scissors! Just make sure to cut it straight. Don’t cut it too short—leave a tiny gap so it doesn’t get stuck on the bottle’s bottom.
Choosing the right pump head for your lotion bottle is not difficult.You just need three numbers, neck size, dosage, and tube length. Next time you shop, jot down those specs and you’ll walk away with a pump that fits, dispenses the right amount, and uses every last drop of product.
