The polyethylene construction of these disposable syringes usually makes them rather chemically resistant. There is, however, a risk of the contents of the syringes leaching plasticizers from the syringe material. Non-disposable glass syringes may be preferred where this is a problem. Glass syringes may also be preferred where a very high degree of precision is important (i.e. quantitative chemical analysis), because their engineering tolerances are lower and the plungers move more smoothly. In these applications, the transfer of pathogens is usually not an issue.

The customer shall cooperate with VWR in all matters relating to the services, provide all such access and information as is necessary and obtain any licences permissions and consents required before commencement of the services. Charles Pravaz and Alexander Wood independently developed medical syringes with a needle fine enough to pierce the skin. Pravaz's syringe was made of silver and used a screw mechanism to dispense fluids. Wood's syringe was made of glass, enabling its contents to be seen and measured, and used a plunger to inject them. It is effectively the syringe that is used today. VWR shall provide services to the customer in accordance with the specification agreed between them from time to time. Such services will be provided with all reasonable care and skill. Disposable Medical Supplies Markets". TriMark Publications, LLC. July 2014. Archived from the original on 2014-02-24.

Medical syringes are sometimes used without a needle for orally administering liquid medicines to young children or animals, or milk to small young animals, because the dose can be measured accurately and it is easier to squirt the medicine into the subject's mouth instead of coaxing the subject to drink out of a measuring spoon. Luer taper, a standardized fitting system used for making leak-free connections between syringe tips and needles. Letitia Mumford Geer patented a syringe which could be operated with one hand and which could be used for self-administered rectal injections. [37] [38]

Syringes for insulin users are designed for standard U-100 insulin. The dilution of insulin is such that 1 mL of insulin fluid has 100 standard "units" of insulin. [6] Since insulin vials are typically 10 mL, each vial has 1000 units.

Examples include the transfer of air-sensitive or pyrophoric reagents such as phenylmagnesium bromide and n-butyllithium respectively. Glass syringes are also used to inject small samples for gas chromatography (1 μl) and mass spectrometry (10 μl). Syringe drivers may be used with the syringe as well.
