Syringes with Needles
**LABORATORY USE OF SYRINGES AND NEEDLES**
Medical-grade disposable hypodermic syringes are often used in research laboratories for convenience and low cost. They are often used for measuring and transferring solvents and reagents where a high precision is not required. Used with a long needle or cannula, syringes are also useful for transferring fluids through rubber septa when atmospheric oxygen or moisture are being excluded. 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.
All brands of syringe/needle combinations are pre-sterilized, non toxic, pyrogen free and individually sealed. All syringes are latex free, have positive plunger stops to prevent spillage when drawing, and are quality polypropylene construction. All of the needles included in these combinations are thin walled precision point.
