The Ultimate Buyer's Guide for Purchasing 1ml Luer Lock Glass Syringes Supplier

At their most basic level, laboratory syringes are nothing more than simple vessels that allow for the transfer of liquid materials. But each type of syringe is best for a specific application, which results in several purchasing considerations, such as:

Goto Kush to know more.

• Sterile vs. unsterile syringes
• 2-part vs. 3-part syringes
• Glass vs. plastic syringes

When it comes to selecting the correct laboratory syringe, it pays to know which one is best for your intended application. 

For example, some lab applications require an ultra-sterile delivery method. A standard 3-part syringe can introduce foreign materials, such as silicon oil, into the process and potentially affect the results. 

At Air-Tite, we carry a wide selection of laboratory and industrial syringes in various sizes, materials, and price points. Read on to learn more about how the right lab syringes can help increase throughput while maintaining process stability, product quality, and compliance.

• Chemical companies
• Food & beverage
• Animal health research

Air-Tite Luer Lock Bulk Unsterile Syringe

Each lab has different needs, but many are overpaying for syringes because they don’t know less expensive, yet quality options are available. Other times, labs may be paying extra for a sterile syringe option that isn’t necessary.

The Air-Tite Luer Lock Bulk Unsterile Syringe is a good option for many lab uses. Air-Tite syringes are typically much less expensive than name brands and yet serve the same function as a basic vessel for the transfer of liquid materials. Our syringes are made to the same ISO standards as other options but have not been filed with the FDA for human use. 

2-Part Syringes

2-part syringes, such as NORM-JECT ® and Henke-Ject®, are also widely used because of their unique characteristics due to the lack of silicone oil and no rubber parts. Chromatography, oils, glues, medicines, and paints all have some level of interaction with silicone oil or rubber and can get contaminated.

Other Types of Lab Syringes

There are several other types of laboratory syringes, such as:

Pre-fill syringes 

Pre-fill syringes are often used for a custom project and a specific application. Lead times can be very long for the first order, and there are instances where procuring a reliable supply can be problematic. Pre-fills are ideal for applications where a substance will need to stay in a syringe for an extended period.  

COC and COP 

COC and COP syringes are more expensive than polypropylene but less expensive than glass. They offer several distinct benefits, such as:

• 100% DMSO compatible
• Shatter-resistant
• Low water and protein absorption
• Multiple designs
• Excellent chemical resistance compared to glass
• Available in silicon-free

Zylar

Zylar is a relatively new entry into the disposable syringe market. It is an impact modified styrene acrylic copolymer that offers exceptional toughness, ease of processing, and low density. It’s also ETO and gamma sterilizable. Zylar syringes work great for injection molded applications that require extreme durability.

Lab work typically requires a standard 18- to 23-gauge needle. However, certain circumstances require specialized needles of different sizes and designs. Given the wide variability of lab applications, several factors should be considered before buying and using lab needles.

For starters, the lab sample's viscosity, material, and volume are key factors to consider. Depending on your specific situation, you may opt for a blunt or sharpened tip. In addition, sterile needles with high-tech safety features protect lab techs and instill confidence in the validity of your results.

Air-Tite is here to help your lab succeed. Before you shop, here’s what you need to know to find the best needle for lab applications.

Learn Why Lab Needle Selection Matters

If there’s one place where precision is crucial, it’s the lab. A lab’s reputation relies on good needles for the predictable delivery of substances for testing and research.

Choosing the correct needle ensures accurate, consistent, and safe lab work. Here’s how:

Accuracy: Needles must have the appropriate inside diameter and length for precise administration of liquids.

Consistency: Quality needles allow for predictable repetition in multiple trials.

Safety: Proper needle selection prevents costly and hazardous leaks and pop-offs.

Selecting the appropriate needle based on application makes procedures easier and preserves sample integrity. Don’t risk dangerous lab accidents or waste precious test materials. The right needles perform as expected to avoid delays and maintain high lab standards.

Consider Needle Uses in the Lab

The needles you select will depend on their intended use, as different applications require specific needle traits. Labs may use needles for liquid handling, sample collection, reagent dispensing, and injecting and sampling lab animals.

Always consider the needle material and intended use to avoid potential reactivity. When handling liquids or dispensing reagents, the viscosity should inform the needle gauge. More viscous liquids require larger needle gauges. Needle length mainly depends on the size of the providing vessel.

For sample collection, choose a sharp or blunt needle depending on where the sample will be obtained. If you’re dealing with lab animals, the needle length and gauge depend on the type of animal.

In addition, sterility is essential to avoid contamination that compromises lab findings. Regulatory compliance with OSHA and FDA should always be considered when selecting lab needles.

Understand Specific Needle Features

Not all needles are the same. Variations include:

• Blunt
• Beveled
• Specialty
• Single-cut
• Spinal needles

Blunt needles have a dull rather than a sharp point, making them the preferred choice for sampling and dispensing in open applications. However, beveled needles have a sharp tip, typically with a tri-beveled design. Beveled needles may be used for sampling in a closed vessel, drawing substances, or injecting lab animals.

Injecting and drawing fluids for unique purposes like invitro-fertilization (IVF) research may warrant the use of specialized bent or angled needles with features like a variable gauge and metal or plastic hubs. Spinal needles have a single bevel with a pointed tip. They’re made with a single cut at an acute angle and may also feature a stylet.

Choosing the right needle diameter based on the liquid viscosity ensures proper flow for a smooth delivery. If the diameter is too small for a thick liquid, it may get stuck, build up pressure, and cause problems like pop-off. On the other hand, thin liquids require a smaller needle diameter for better control. The sample volume is another critical factor when choosing the right needle. Smaller volumes require a finer needle gauge to reduce waste and ensure accuracy.
