Syringes with fixed needles are a convenient tool with several benefits. For one, there’s no need to physically install the needle on the syringe when it is already mounted. By minimizing the required preparation steps, syringes with needles can help reduce the chances of human error. However, there are still some key safety tips to remember when using sharp implements, especially when handling hazardous liquids. Read on for insider tips on how to use syringes with needles safely and select the right dimensions for the best results.

How Do Syringes With Needles Work?

here are foTur options when it comes to syringes and needles:

• Syringes and needles separately: The user must install the needle before use.
• Bi-packed syringes and needles: The needle is packaged alongside the syringe, but the user still needs to install the needle on the syringe.
• Mounted needle syringe combination: The needle is pre-installed on the syringe and is ready to use straight from the package.
• Fixed needle syringe: The needle is molded directly into the syringe body.

You may prefer to stick with syringes you’ve used in the past, but many different brands and varieties are available. It’s important to consider the safest and most appropriate set-up to serve your current needs.

Finding the Right Specifications for Your Application

Despite the many benefits of syringes with needles, it’s crucial to tailor your selection based on the task. After considering the overall brand quality, choose a syringe with the appropriate volume capacity, needle length, and gauge. For example, using an insulin or fixed-needle syringe for multiple injections can lead to a dull and ineffective needle. However, these types of syringes are a simple and convenient option for self-injecting insulin at home. On the other hand, mounted syringes are ideal for hospital and alternate care.

Luer slip syringes have needles that are easy to install and remove. As a result, they’re best when you want to save time while performing a series of injections where multiple needles are required. However, for instances with a higher risk of the needle and syringe coming apart (such as when working with highly viscous fluids), luer lock syringes with needles ensure a more secure attachment.

When choosing needles, look for the proper length and gauge. Key factors to consider include the intended application, the viscosity of the material, and the origin container. Select a needle that’s long enough to reach the liquid without requiring you to tip the container and risk spills. Overly long and thin needles make it harder to draw up viscous liquids and are more likely to fall off or buckle under pressure.[1]

Best Safety Practices to Keep in Mind

You can stay safer when using syringes with needles by:

• Using extra care when taking the cap off the needle
• Avoiding accidental needle sticks by making sure your hands and body stay behind the plane of the needle
• Pulling the plunger back slowly and not pulling it too far, especially when withdrawing hazardous substances
• Gently dispensing the liquid so as not to cause pop-off from applying too much pressure
• Disposing of uncapped needles in a sharps container as soon as you finish using it

You can also insert needles into a cork or rubber stopper to store them safely. However, don’t use your hands to hold the stopper. Just leave the stopper on a flat table and stick the needle in with one hand. You can also place a syringe with an attached needle into a flask or plastic centrifuge tube in a rack (needle-side down) when not in use.

Keep in mind that the safety stop on a syringe won’t prevent the plunger from being fully pulled out of the barrel. This feature is designed to warn the user that they are approaching the limit of the plunger’s movement. Different syringes require different levels of force to pull past the safety stop.

Finally, never use a syringe with a capacity of over 10 milliliters for dangerous materials like pyrophorics. When a syringe is too big, managing it can be awkward, leading users to employ too much force. If the needle pops off, there’s a risk of exposure to hazardous liquids that can cause burning or other emergencies. Instead, it’s safer to cannulate the liquid into and out of a measuring cylinder.[1]

Where to Get Syringes With Needles

Air-Tite has the largest selection of syringes and needles in one place. We also have experts to answer your questions and help you shop for the best options for your money.

Our catalog and website feature high-quality B. Braun Omnifix® Luer Lock Syringes made in Germany. Slow aspiration and injections are made easy by the rubber piston with a double sealing ring made of polyisoprene. The polystyrene plungers have an integrated backstop to prevent accidental withdrawal. In addition, they’re free of latex, PVC, and DEHP.

We have fixed needle options, such as Exel Insulin Syringes and HSW Syringes.

It’s tough to beat the value you’ll find in high-quality syringes from Exel International. Their insulin syringes with fixed needles have low dead space to prevent wasted products. They also feature smooth siliconized gaskets, bold printing, and clear graduation markings for a user-friendly syringe.

The HSW Syringe with a fixed needle also has low dead space. It features tuberculin markings and bolder graduations and underwent a recent redesign to improve the packaging and syringe barrel clarity.

For veterinary applications, consider the Exel Vet Insulin Syringe with a fixed needle or Air-Tite’s Luer Slip Syringes or Luer Lock Syringes with mounted needles. The mounted needle allows the user to open a single product for the draw-up without any assembly. In addition, the larger draw-up needle is more likely to pierce the vial septum easily without damaging the ultimate injection needle or causing unnecessary pain for the patient. We also carry a variety of BD Syringes with needles from the world’s largest syringe manufacturer.
