Syringes and Needles
Syringes are used widely in the laboratory for sampling, fluid aspiration, injecting, measuring and transferring liquids and gases with dispensers, dilutors and chromatography autosamplers, and for septum piercing or pressure-filtering through syringe filters.
Our syringes are available with fixed or removable needles with Luer Lock, Luer Tip or Luer-Slip fittings, graduated for accurate measurements, and as plastic or glass, sterile or non-sterile, disposable or reusable.
Luer Lock fittings allow a needle to be securely twist-locked into position onto the syringe body, minimising the risk of needle displacement. Conversely, Luer-Slip (slip-tip) fittings are simply pushed on and held in place by friction. The tip position of Luer-Slip syringes can be either eccentric or concentric.
Single-use syringes can be constructed from two or three components, excluding the needle. Three-part syringes comprise a plunger, a rubber plunger gasket cap and a transparent and graduated barrel. Two-part syringes comprise only the plunger and barrel without a separate rubber plunger cap.
Fisher Scientific provides a variety of separate needles, ranging from general purpose to hypodermic to specialist, with different point styles, gauges from 30G (the finest) to 21G (the thickest), lengths, all available sterile or non-sterile in variety of packaging options.
Our range of syringes and needles can be used for:
- General laboratory or clinical use
- Filtrations (in combination with a syringe filter) for a broad range of applications, including purification of tissue culture solutions and buffers, and filtering of protein solutions and solvents
- Fluid transfer into tubing arrays (without the use of a needle if necessary)
