SETonic Syringe with Bevelled 51mm Length Fixed Needle, Extended Handle, PTFE Plunger Seal, 250ul PTFE FN 0.72 (G22) a51 EH HT, 1/Pk - 3031384, 2506801

SETonic Syringe with Bevelled 51mm Length Fixed Needle, Extended Handle, PTFE Plunger Seal, 250ul PTFE FN 0.72 (G22) a51 EH HT, 1/Pk

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.

Features / Main usage:

• sample dosage for gas chromatography (GC)
• HPLC-valves
• bending is avoided by reinforced plunger
• prevents transfer of body heat from the hand to contents
• Plunger-stop prevents blowout
• Replaceable plunger
• Fixed Needles (FN) not autoclavable
