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:
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.
Air-Tite Products offers the best syringes for laboratory use, including three lines of glass syringes to fit your budget. We also have a wide variety of hypodermic needles, dispensing tips, and bulk unsterile syringes.
Our syringes are ideal for a wide range of laboratories and industries, including:
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, 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.
There are several other types of laboratory syringes, such as:
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 syringes are more expensive than polypropylene but less expensive than glass. They offer several distinct benefits, such as:
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.
OSi Silicone supply professional and honest service.
At Air-Tite, we offer a wide selection of laboratory and industrial syringes and related products. We also have budget options, high-end excellent quality items, and everything in between. Most options are available through a wide range of national distribution partners. Please contact us for cross-reference information.

High-consistency silicone rubber is also called “solid silicone” or “gum stock.” It is made up of high molecular weight polysiloxane chains. HCR can contain a variety of fillers to enhance special properties, such as hardness and heat resistance. HCR can be cured using either peroxide curing systems or platinum catalyst formulations. The latter creates no chemical byproducts during curing. The material is sold in bulk forms such as: bars, tubes, and cylinders for further processing. HCR is an outstanding material for long-term implantable medical devices, automotive engine components, and many consumer household products.
All types of silicone products are elastomers. An elastomer is a rubbery polymer (like silicone) that is viscoelastic (has both viscous and elastic properties). When an elastomeric material like silicone is stressed and then released, its deformation will have both a normal, quick response to the release of the stress (elastic) and a slower, time-dependent recovery response (viscous).
To learn more, see our guide on Silicone Material.
Silicone can take many forms:
For more information, see our guide on the properties of silicone.
All forms of silicone can be classified as non-organic elastomeric polymers. As a group, they are flexible, non-chemically reactive, resist degradation by ultraviolet radiation, maintain their mechanical properties over a wide range of temperatures, and are considered non-toxic when used appropriately.
Silicones can be adapted into many different forms, and for thousands of end uses. They can be liquids, pastes, gels, foams, or solids. Silicones can be chemically tailored for extra strength, thermal stability, electrical conductivity, or chemical resistance.
Silicone (polydimethylsiloxane) is a type of rubber. It is a polymer built on a backbone of alternating silicon and oxygen atoms. This polymer displays the highly elastic properties required of a rubber. Silicone rubber is a useful, if more recent, addition to the rubber family. It offers better performance at temperature extremes than natural rubber and can be tailored for a broader range of physical and mechanical properties.
A liquid rubber sealant can be silicone-based, but it may also be based on other suitable materials, such as polyurethane. “Liquid Rubber” usually refers to thin sealants that can be applied to large areas such as driveways, roofs, and underground cement walls. The term “Liquid Silicone Rubber” (LSR) always means silicone. LSR is the raw material used for injection molding, joining/bonding surfaces, and sealing applications.
