Attach a needle with a luer lock connection to dispense contents. Needles with a luer lock connection have a more secure needle connection than those with a luer slip connection. A curved plastic tip fits into bearing seals, narrow holes in housings, and around small parts in 3D printers and other machinery. Use these syringes to control the direction of flow so you don't make a mess. They do not have graduations. Use these barrels with an air-powered dispenser to make repetitive dispensing easier on your hands.

Syringe barrels with a luer lock connection require a needle with a luer lock connection to dispense contents. Syringe barrels with a taper tip can be trimmed to any size. Choose a black syringe barrel to dispense light-activated contents, such as adhesives. Cover syringe tips when not in use to protect them and prevent leaks. Often used in chromatography applications, these filters attach to any syringe with a luer lock connection to filter out contaminants both when drawing in and dispensing.

PTFE filters have better chemical resistance than nylon filters. Glass filters are often used before plastic filters to capture larger particles. Transfer small quantities of liquid one drop at a time.

Style A dropper has a fine tip to dispense thin liquids. Style E dropper has a wide tip to dispense thicker liquids. Style F droppers have a removable bulb for easy cleaning. Also known as basters, these dispensers transfer larger amounts of liquid than bulb droppers.

I'm trying to figure out what kind of materials my disposable plastic syringe is made from. I have a Medefil MIS syringe and when I visited the company website I couldn't find any information on what the disposable syringes were made from although they did tell me a lot on what's NOT in them. I'm trying to find a regulation or something that could help me identify what kind of plastic and rubber are used to make the shill, plunger and seal that make up the disposable syringe.

Can anyone on here please give me some guidance? This is suspiciously vague and does not necessarily mean that the product complies with all requirements of all relevant ISO standards.

Ideally, such prefilled syringes are made in accordance with the applicable standards of the ISO Prefilled syringes series and other documents that are referenced in these standards e. However, the normative minimum requirements for materials are very general and not very restrictive. For example for the material of the barrel according to ISO Prefilled syringes — Part 6: Plastic barrels for injectables:.

For the manufacturing of the barrels, suitable polymers shall be selected and used, based upon the intended application and processing techniques, which include, for example, the method of sterilization or the method of decontamination. The material shall exhibit the appropriate performance properties, e. The elastomeric material used shall meet the requirements specified in Clause 7. Plunger stoppers shall be made from the elastomeric formulation originally tested and approved by the end user.

The manufacturer of the plunger stopper shall ensure the conformance of each delivery with the type sample and compliance with previously agreed functional and compendial requirements. If other sterilization methods are used, e. Alternatively, the hardness can be tested on the plunger stoppers in accordance with ISO The maximum time between the date of manufacture of the plunger stoppers and their pharmaceutical use should be agreed upon between the manufacturer and the user. The plunger stoppers shall maintain their performance characteristics throughout the entire shelf-life of the medicinal product, which is tested as part of the stability test by the user.

In addition to the normative minimum requirements, ISO also includes informative guidance on materials:. Materials used in the construction of syringe barrels for use in pre-filled syringes should be suitable for the process to be used, the sterilization method to be applied and for the specific requirements as primary packaging for injectable drug products.

Materials used in the construction of pre-filled syringes should not cause the syringes to be detrimentally affected, physically or chemically, by the normal use of injectable preparations and should be safe for the intended use.

The organization responsible for the marketing approval of the injectable drug product is required to demonstrate the appropriateness and compatibility of the selected material and the suitability of the prefillable syringe as a container closure system. To develop the necessary data as outlined above, a collaborative approach is recommended between the pharmaceutical company that holds the marketing authorization of the injectable product and the supplier of the packaging system, with reference to ISO For reliable information, you should directly inquire from the manufacturer of the prefilled syringes.

Apparently, this company does not make the empty syringes but only fills syringes that are obtained from another supplier. Sign up to join this community. The best answers are voted up and rise to the top. Home Questions Tags Users Unanswered. What kind of materials are plastic syringes made from?

Depending upon the customer requirements, various packaging options are available. In order to complete the syringe system, we offer appropriate plunger rods in the most varied sizes, materials, and colors. The backstop reduces the opening diameter of the syringe body and simultaneously enlarges the finger flange with ergonomically shaped wings.

In this way it fulfills two functions. First, the backstop prevents the plunger stopper from being pulled out of the syringe. Second, the backstop eases the handling of the syringe thanks to an enlarged finger flange area.

This is helpful with viscous medications or in the case of counterpressure from the tissue, and in addition to this also benefits even patients with limited motor capacity when injected by the user. Our backstop is made of plastics and manually clipped to the finger flange of the glass syringe.

It is thereby compatible both with round and cut finger flange shapes. The backstop is available in various colors and can be used as a visual indicator for the user in order to prevent confusion. The needle shield protects the cannula against deformation up to injection, and keeps the cannula sterile until use.

Steve Hourmezian.In designing your experiment and setting up your syringe pump, it is important to choose the correct syringe material type for your application.

Chemyx syringe pumps support a wide variety of syringes and its versatile software enables the user to quickly and efficiently select a syringe from the syringe librarywhich lists syringes by the manufacturer. Alternatively, users can manually input the physical characteristics of the syringe. When choosing a syringe type for your experiments, it is important to consider whether the syringe is chemically compatible with your sample.

Other important considerations are syringe cost and durability.

The physicochemical characteristics of a syringe are mostly dictated by their material of construction. Commercially available syringes are typically made of glass, polymer plastic or stainless steel. Here are some of the advantages and disadvantages of glass, plastic and stainless steel syringe material types. Glass syringes are the most widely used in syringe pump applications.

They are available in a variety of sizes including microliter volumes, enabling experiments with extremely small injection volumes. Additionally, glass syringes have a high gas barrier, which is good for oxygen-sensitive applications 1. However, there are some negatives associated with glass syringes.

Glass is susceptible to breakage. Chemical interaction between the sample and glass can lead to delamination, whereby the glass corrodes or flakes 2. This can be of particular concern if your samples contain demetallated or apo proteins. Contamination can also originate from adhesives, silicon oil and elastomer components that are typically added to glass syringes 1.

These contaminants can significantly influence your experiments, particularly when working with sensitive biological samples and proteins. For example, silicon oil lubricated glass syringes have been found to increase protein loss in biological samples through the formation of insoluble aggregates 3. Plastic syringes have become a popular choice in recent years.

They are cheaper and more durable than glass syringes, are typically free from heavy metals and tungsten and have little to no siliconization 1. Additionally, plastic syringes can become discolored and hazy upon repeated sterilization [1]. Although plastic syringes are widely available in a variety of sizes, they are generally not available in small microliter sizes.

If you are using high flow rates and viscous samples, you are likely to encounter high syringe pressures. In these cases, you may require a stainless steel syringe. Stainless steel syringes are extremely durable, have low volume errors and high chemical resistance.

However, these syringes can be harder to load than glass or plastic syringes because it is not possible to visually detect air bubbles; additionally, you cannot monitor samples for precipitation during the course of the experiment. Stainless steel syringes are generally more expensive than glass and plastic syringes and are typically only available in larger volumes.

For these reasons, stainless steel syringes are normally only used in high-pressure applications. In preparing to use your syringe pump, it is important to choose the correct syringe material type. Syringes are typically available in glass, plastic and stainless steel. Glass syringes are most common; they are available in a variety of sizes including in the microliter range, are great for oxygen sensitive samples and have low volume errors.

However, glass syringes can break and they can sometimes contaminate your samples with metals, adhesives, silicon oil and elastomer components. Plastic syringes are cheaper than glass syringes and have less potential contaminants. However, they are less suitable for oxygen sensitive samples and can become discolored upon repeated sterilization.

Furthermore, plastic syringes have larger volume errors. Stainless steel syringes have high chemical resistance and low volume errors and are ideal for high-pressure applications because of their durability.

However, they are more expensive, are only available in larger sizes and can be more difficult to use because they are not transparent. Users should consider all factors when choosing their syringe material type, including the chemical composition of the sample, implications of contamination, desired injection volumes, and anticipated experimental pressures.

Alexa Actionable Analytics for the Web.The hypodermic syringe, also known as the hypodermic needle, is a device used by medical professionals to transfer liquids into or out of the body. It is made up of a hollow needle, which is attached to a tube and a plunger.

When the plunger handle is pulled back, fluids are drawn into the tube. The fluid is forced out through the needle when the handle is pushed down. The syringe was introduced in the mid s and has steadily improved with the development of new materials and designs. Today, it has become such an important medical tool that it is nearly a symbol synonymous with the practicing physician.

Since the advent of pharmaceutical drugs, methods for administering those drugs have been sought. Various important developments needed to occur before injections through a hypodermic syringe could be conceived.

Early nineteenth century physicians were not aware that drugs could be introduced into the body through the skin. One early experiment that demonstrated this idea, however, was performed by Francois Magendie in In his published work, he outlined a method for introducing strychnine into a dog by using a coated wooden barb.

InA. Lesieur described another method for administering drugs through the skin, applying them directly to blisters on the skin. Expanding on results from these experiments, G. Lafargue developed a procedure for introducing morphine under the skin using a lancet. A drip needle was invented by F. Rynd in for the same purpose. However, he did not publish his method untileight years after the first hypodermic syringe was described.

The first true hypodermic syringe was created by Alexander Wood in He modified a regular syringe, which at that time was used for treating birthmarks, by adding a needle. He then used this new device for introducing morphine into the skin of patients who suffered from sleeping disorders.

A few years later, he added a graduated scale on the barrel and a finer needle. These modifications were enough to attract the attention of the rest of the medical community, resulting in its more widespread use. Over the years hypodermic syringes have undergone significant changes that have made them more efficient, more useful, and safer. One such improvement was the incorporation of a glass piston within the cylinder.
