SS Stainless Steel gold coated
SS-Gold coated * - Gold coated stainless steel, developed for use with aggressive solvents (e.g. strong acids)
PTFE NUB Compount

PTFE NUB is specialy developed compound for microsyringe application to increase lifetime:

⇒ high chemical resistance ⇒ less friction than virgin PTFE ⇒ less electronic charge

⇒ higher robustness ⇒ less "cold flow" ⇒ higher longevity

PE-HD Seal Plunger
With better durability than virginal PTFE when working with saline solution
PTFE Seal Plunger

Gas tight sealing of the plunger tip, for most solvents and chemicals

PTFE is a fluorocarbon solid, as it is a high-molecular-weight compound consisting wholly of carbon and fluorine. PTFE is hydrophobic: neither water nor water-containing substances wet PTFE, as fluorocarbons demonstrate mitigated London dispersion forces due to the high electronegativity of fluorine. PTFE has one of the lowest coefficients of friction of any solid.  We use best quality virgin PTFE from selected sources only. The seal design is depending on syringe type and application.
