A three-step guide to choosing the right pipette dropper

Right off. Why choose a pipette dropper as closure for your Miron bottle? Why not a pump, spray, or vertical dropper? There are three main reasons:

  • You want to dosage your product
  • You want to apply your product to specific areas only
  • You want your product to not get contaminated

Pipette droppers are a great way to dosage the liquid inside. With either the pipette dropper's size or with markings on the glass tip, your customers can always be sure to use the right amount of your product. This is especially relevant for nutrition products, essential oils, skincare cosmetics, CBD products, and other natural healing remedies.

Suppose your natural product needs to be applied to a specific skin area only, for example, just on the fingertips or the skin under your eyes. Pipette droppers ensure that your product only touches the places it was meant for with the extra perk that it does not get contaminated by being touched.

 

3 steps to choosing the right pipette dropper.

That's why pipette droppers are used. However, the question of how to choose the best one for your natural product still remains. Let's get into that.

A pipette dropper consists of four different parts:


  • The Bulb
  • The Cap
  • The Glass Tube 
  • The Glass Tip

 

Step 1 - The Bulb

The bulb is made out of rubber and controls the dosage. So, simply put: The bigger the bulb, the bigger the dosage. The bulb comes in different sizes and indicates how many milliliters can be sucked in by squeezing it. And that's what the number stands for 0.4, 0.7, and 1.0 refers to the amount of ml.

The difference between TPE and NBR? TPE stands for thermoplastic elastomer and is the standard bulb most commonly used for alcohol-based and low acidity level products that can't damage the rubber bulb. NBR, nitrile rubber bulb, is a specialized bulb for oil-based and high acidity liquids.

If you wonder what acidity level is high or low, the answer is not as straightforward as it may seem. A general rule of thumb is: The purer the product, and the fewer oils or alcohols are added, the higher the acidity level. But every product is different.

We advise you to test your product with both bulbs first.



So, ask yourself in Step 1:

  • How many milliliters do I want the pipette dropper to release per use?
  • Is my product oil- or alcohol-based?

 

Step 2 - The Cap

There are Type III and child-resistant (CR) tamper-evident caps. Tamper-evident means that they have a plastic ring at the bottom of the cap that breaks after first time opening. They act as quality control for the customer. An intact ring means the bottle has not been opened before.

The child-resistant cap needs to be pushed down and turned to open. When it comes to deciding which cap is best for your natural product, the main question is if the content needs to be protected from children. CBD products, for example, often need CR closures.


The question to answer in Step 2:

  • Do I need a child-resistant closure?

 

Step 3 - The Glass Tube & Tip

Just as the bulb, the size of the glass tube is essential for getting the dosage right. Either the glass tube holds the right amount of milliliters, or the tube is marked to help your customer's dosage.

The length is also relevant because it needs to match the bottle's height to ensure you reach the bottom. If the pipette cannot reach the bottom, some of the precious product remains in the bottle.

Straight versus bent spherical tip? The main difference is that the bent spherical tip shape creates perfect drops of your product when dropped out. The straight shape releases all product at once. The straight shape is mostly used when a volume rather than a specific number of drops is relevant.


Questions for you to answer in Step 3:

  • How many milliliters do I want the pipette dropper to release per use?
  • Do I need a pipette dropper that creates liquid drops or releases all at once?
