What is a hypodermic needle?
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 1800s 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.
What is a syringe for?
A syringe is one of three primary methods for introducing a drug into the body. The others are transepidermal (through the skin) and oral. Using a hypodermic needle as the method of drug administration has some significant advantages over oral ingestion. First, the drugs are protected from the digestive system.

Is a syringe ISO compliant?
The syringes are advertised as “ISO compliant” on the website of the manufacturer. This is suspiciously vague and does not necessarily mean that the product complies with all requirements of all relevant ISO standards. (Also note that, concerning compliance and quality, the website mentions that the manufacturing facility is “ISO certified”, which is not permissible. However, the manufacturer actually has been certified to comply with ISO 9001:2008 and ISO 13485:2003 – that’s more like it.)
General Factors To Consider When Choosing Your Syringe Material Type
In designing your experiment and setting up your syringe pump, it is important to choose the correct syringe material type for your application.
Glass Syringes
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. They generally have small volume errors (typically ~1%) and are thus ideal for high precision work.
Plastic Syringes
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.
Stainless Steel Syringes
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.
Conclusion
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.
