Syringe Cleaner

Proper Syringe Care Ensures Consistent Injections and Long Syringe Life
Syringes are precision instruments. The care you take in using, handling, and storing them are keys to consistent injections, quality chromatograms, and long syringe life.
  • Generally, for consistently accurate injections, the sample size should not be less than 10% of more than 80% of the syringe′s capacity.
  • Temperatures above 50°C can damage most fixed-needle syringes, due to expansion of the metallic needle.
  • Routinely inspect your syringe for damage. Look for hairline cracks, and discard any syringe with a potentially unsafe barrel. The needle tip must be free of barbs. Barbs will tear the septum, creating particles that can clog the needle or deposit in your chromatographic system.
  • If your syringe contains a PTFE tip, be sure to replace the plunger and tip assembly immediately if metal is exposed. The exposed metal plunger scrapes the glass of the syringe barrel, producing glass fragments that cut grooves in the PTFE tip. These groves allow sample to teak past the tip. Caustic samples or cleaning solutions that seep under the PTFE tip destroy the sharp barb that holds the PTFE tip on the plunger. The tip, when loosened, could slip off during sample aspiration.
  • Never store a syringe without cleaning it. Use caution when cleaning syringes containing epoxy glue or PTFE materials.
  • Epoxy glue is not completely resistive to every solvent. A solvent such as methanol, methylene chloride, acetonitrile, acetone, or butyl amine (and others) can result in a contaminated plunger, adherence of the plunger into the barrel, a loose needle, or a clogged needle.
