Choosing the right pipette dropper.

Pipette droppers are a great way for dosing a liquid precisely and without contamination. This is especially relevant for nutrition products, essential oils, skincare cosmetics, CBD products, and other natural healing remedies.

A pipette dropper consists of four different parts, which can be configured to suit your product and usage best. These steps make you an expert in minutes. But, even as an expert it is wise to ask the help of our sales representative and to request samples.

1) Bulb material & dose.

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 (dose: 0.4 ml, 0.7 ml, and 1.0 ml) and indicates how many millilitres can be sucked in by squeezing it. 

  • thermoplastical elastomere (TPE)
    TPE bulbs are ideal for products that are either alcohol-based or have low acidic levels, as these are not harmful to the rubber. Pipettes with chlorine butyle (CB) have similar properties.
  • nitrile butyle (NBR)
    The NBR bulb is specialized for being used with oil-based or highly acidic liquids.

2) Cap design & function.

The cap is screwed on the bottle. It is important to look at the thread of the cap, like DIN18 or 18/415. These codes refer to the diameter and screw thread of the bottle to make it fit perfectly. Caps come in different series of styles, each with its own functionalities. For example, tamper-evident means that they have a plastic ring at the bottom of the cap that breaks after the first time opening. They act as quality control for the customer. An intact ring means the bottle has not been opened before. 

  • series II
    The tamper-evident Series II closures are made from a single mould, having 4-6 ridges on the side.
  • series III
    The tamper-evident Series III closures have a thicker rim and are made from multiple moulds. This pipette cap has a stepped design.
  • child-resistant
    The tamper-evident child-resistant cap needs to be pushed down and turned to open for usage. This additional barrier reduces the possibility of children ingesting unsafe liquids.
  • push-button
    This pipette is dosed by a button instead of squeezing a bulb. Giving it a totally different look and experience, ideal for cosmetics purposes.

3) Tube length.

A pipette needs to fit the bottle perfectly. If the tube is too long, it easily can break or will not fit at all. If the tube is too small, it makes it hard to extract all precious liquid from the bottom of the bottle. So, in most cases, we have exactly named the corresponding bottle.

4) Type of tip.

The finishing touch is literally the tip, as it defines the customer experience in dosing. Is the dosage a precise drop, or more a volume shot? Choose your tip wisely, be it a ball – straight or bent, or concial.

  • ball-bent tip
    The ball-bent tip makes perfect drops enabling you to dose drop by drop. The bent tip could have another minor advantage. You can reach the liquid that sitting in the corner bottom of the bottle.
  • ball-straight tip
    The ball-straight tip makes perfect drops enabling you to dose drop by drop on a specific spot. 
  • conical tip
    This tip is used when the product needs to be dosed in ml instead of drops. This tip also comes with graduation (measuring marks on the tube).
