2 Part Syringes

Syringes are the most commonly used medical and industrial instruments, but 'syringes' is just a general term, there are many different types of syringes on the market, to meet specific needs.

As two of the more common syringes, 2 part and 3 part syringes are both having qualities that make them ideal for a wide range of applications.

Sometimes, a researcher or engineer may hard to identify the source of various pollution in their process.  One possibility is either the rubber or silicone oil in 3 part syringes. If that becomes obvious in your process, then you may have another choice - a 2 part syringe. Two-part syringes are briefly different since they do not use a rubber on the plunger tip to create a vacuum seal. On the contrary, they have been designed specially to avert other materials such as rubber or silicone oil.

Three-part syringes typically require a lubricant (most often silicone oil) to prevent the rubber from “grabbing” the barrel sides as it slides up and down. The rubber on the plunger tip acts as a sealant against the barrel and creates a vacuum for drawing material into the syringe. To prevent the sticking of the rubber against the solid material of the barrel, a manufacturer sprays the lubricant into the barrel during the assembly of three-part syringes. While standard three-part syringes are used for a much wider range of applications, two-part syringes offer distinct advantages for some applications.

To circumvent added lubricant, two-part syringes use an exactly engineered, slightly oversized plunger head that expands the barrel to create the vacuum. The design allows for a smooth gliding plunger to keep vacuum pressure without the rubber gasket.  These syringes are useful for many sensitive applications, like chromatography, ophthalmics, industrial solvents, glues, paints and various laboratory applications.
