Benefits of Upgrading from Squeeze Bottles to Fluid Dispensers

More Accurate Dispensing Can Increase Production Speed by Up to 40%

Surprisingly, more than 50% of industrial and manufacturing plants in the United States are frequently using squeeze bottles, medical syringes, Q-tips®, and toothpicks to apply fluids in their assembly processes, despite the many advances in fluid dispensing technology.

These findings come from a 2017 survey conducted by Clear Seas Research, and sponsored by Nordson EFD. About 290 companies in various manufacturing sectors responded. They were asked to rank the dispensing methods they used most often. They selected multiple methods from most frequently used to less frequently used.

Here are the most frequently used fluid dispensing methods in the U.S. according to the 2017 survey:


In this blog post, we’re going to discuss the many benefits of upgrading your dispensing method from rudimentary squeeze bottles, syringes, toothpicks, and Q-tips to precision air-powered benchtop fluid dispensers.

Benefits of Using a Fluid Dispenser

Most manufacturers likely start out with manual squeeze bottle and medical syringe dispensing. Then, as production volumes increase, some progress into employing more controlled approaches with precision benchtop fluid dispensers or pneumatic valve systems for at least part of their fluid dispensing. Performus X100 Dispensing Frost

While others follow a different route ─ instead of upgrading ─ they maintain their manual squeeze bottle dispensing processes, adding on more production stations and more workers to handle the increased volume.

Viewing these two approaches from a production capacity perspective, there are several benefits of adopting a more efficient and controlled fluid dispensing method. Here are just a few.

  1. Shot-by-shot repeatability and accuracy are considerably improved with air-powered dispensing compared to manual squeeze bottle dispensing. Per the recent results from the Clear Seas Research Study, shot-by-shot repeatability and accuracy are two of the most sought-after improvements desired by respondents. Depositing the right amount of fluid has a compounding consequence of keeping downstream production moving. For example, if too much fluid is applied, the longer it can take to cure, which will delay production downstream. Conversely, if too little fluid is applied, the part will not properly bond, again interrupting downstream assembly or causing a failure in the product.

  2. Increased productivity is clearly a benefit of air-powered benchtop dispensing over manual squeeze bottle processes. For example, the same worker who manually assembles 800 parts during an eight-hour shift can assemble 1,000 to 1,200 parts with the assistance of an air-powered fluid dispenser. That’s a production throughput increase of up to 40%.

  3. Part quality often improves when switching from manual squeeze bottle dispensing to air-powered dispensing because operator-to-operator variance is reduced. The ability to set the time, pressure, and other dispensing parameters for an application improves process control and ensures the right amount of fluid is placed on each part.

  4. Rework and reject rates lessen when upgrading to air-powered dispensing. In some electronics and medical device factories, one rejected part caused by poor manual squeeze bottle fluid dispensing could waste hundreds or even thousands of dollars.

  5. The amount of assembly fluid used decreases significantly when using a more controlled method like air-powered dispensing. Switching from a rudimentary manual dispensing process, for example, to an air-powered dispenser can cut the amount of fluid used typically from 50 – 70% due to the improved accuracy of the deposit. When dispensing components are designed to work together to minimize fluid waste it can add up to significant savings.

In summary, though there may always be some degree of manual squeeze bottle dispensing required in assembly, manufacturers that are heavily dependent on squeeze bottles, medical syringes, and toothpicks for a sizable portion of their fluid dispensing, no matter how precise or imprecise their dispensing parameters might be, can greatly benefit by taking a closer look at their production capacity.

Doing a cost-to-benefit comparison between the methods they are using and a more precise solution such as an air-powered dispenser helps. It is critical, however, to consider each of the five points listed, as many of them represent hidden costs affecting the real cost-to-benefit rating of manual squeeze bottle, toothpick, swab, and medical syringe dispensing processes.
