The dispense tip also referred to as a dispense needle is a vital part of liquid dispensing systems. As you choose a dispense tip, you should contemplate on a number of things. You should consider if the tip is working and ideal for the task at hand. Precision dispensing tips have angles, lengths, gauges and threads among other features that vary to optimize dispensing accuracy and repeatability for the type of liquid and application.
There is a wide selection of dispense needles on the market, including PTFE-lined, brush, angled blunt end, blunt and tapered dispense needles. These needles are made of a wide range of materials, including Teflon, stainless steel and polypropylene. As you dispense fluids, it is essential to choose the right dispense needles for the syringe. The type of needle you need depends on the kind of fluid you are dispensing.
It is vital for the gauge, length and shape of a dispense tip to meet the needs of your application. This way, the liquid will be accurately deposited and the whole dispense system will work optimally. One of the reasons why several types of dispense needles exist is due to availability of fluids with unique properties. The needles are designed to meet different application needs. If you were to use an incorrect needle, your cycle rates, rejects and reworks would increase, leading to poor part quality and a wasteful production process.
The general purpose tip is the most common dispense tip available. It is versatile meaning that you can use it to dispense many different types of assembly fluid. Nonetheless, the ability of the general purpose dispense tip to dispense many different types of fluids, it may not be the suitable tip for your application. You should select the tips that can dispense the correct amount of fluid as quickly as possible.
When dispensing low or thin viscosity fluids, it is advisable to use a general purpose tip with a small diameter. The choke point of such a dispense tip will limit the movement of thin fluids to ensure better control of the dispensing process. Nevertheless, if you want to dispense solvents, it would be recommendable to choose a dispense needle that is PTFE coated. The outer coating will prevent the fluid from wicking up on the cannula. This will ensure that the deposits are accurate and enhance repeatability.
When you want to dispense thicker viscosity fluids, tapered tips are ideal. The tapered dispose needles enhance flow and this will enable you to dispense a large number of accurate and consistent fluid deposits within a short time frame. When using tapered dispense needles, you can reduce the pressure on a pneumatic fluid dispenser.
The dispense tips from different companies may look alike, but they are different in terms of quality. It is advisable to buy the tips from a company whose quality control process is stringent. High quality dispense needles are devoid of burrs or molding flash that can pollute the material or change the quality of your liquid deposits.
You should confirm that the dispensing components such as the dispense needles, adapter assembly, syringe barrel and piston are designed to work together well. These components should offer precise and consistent fluid deposits without wasting a lot of fluid. This will translate to savings over the years.
