You need to pick a needle that matches your job. Think about what kind of fluid you will use. If you use thin fluids, choose a needle with a small tip. This helps you control how much fluid comes out. For solvents, a PTFE-coated tip works best. It stops the fluid from spreading and helps you be more exact. If you use thick fluids, pick a SmoothFlow tapered tip. This shape lets thick fluids move without getting stuck. It also means you do not need to push as hard. You can finish your work faster and waste less.
Thin fluids: Small tip for better control
Solvents: PTFE-coated tip for accuracy
Thick fluids: Tapered tip for easy flow

The needle material is important too. Stainless steel lasts a long time. Plastic is good for some chemicals. Pick the tip shape for how you want to use the needle. Blunt tips are for most jobs. Tapered tips are good for thick fluids. Flat tips touch a bigger area. Make sure the needle is long enough to reach where you need. Check if the connection, like Luer lock or M5, fits your tool. Ask the company if you need a special size.
Gauge: Match to fluid and dot size
Material: Stainless steel or plastic
Tip type: Blunt, tapered, or flat
Length: Make sure it is long enough
Connection: Fits your dispenser
