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 dispense needle that is most common is the general purpose needle. The main benefit of this dispense needle is versatility. You can use it to dispense most kinds of assembly liquids. Even though this dispense needle can dispense almost all kinds of liquids, it may not be the best kind of tip for your application. You ought to select a needle that will dispense the correct amount of liquid fast.
When planning to dispense the fluids with a low viscosity, you can utilize a general purpose needle with a smaller diameter. Its choke point will limit the flow of thin fluids to ensure better process control. When dispensing solvents, it is advisable to choose a PTFE coated dispense tip. With such a needle, the fluid will not wick up on the exterior of the cannula because of the special exterior coating of the tip. This can improve repeatability and the accuracy of deposits.
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.
Even though the dispose tips of one company may appear identical to those of another company, they are not the same. Therefore, ensure that the company you choose to buy dispense tips from adheres to a strict quality inspection process. The best dispense needles do not have molding flash or burrs that can contaminate your material or change the consistency of your fluid deposits.
