Plunger Force Adjustment Video Tutorial ILS glass syringes are manufactured to exacting standards and are quality tested to meet or exceed our minimum performance specifications for accuracy and precision. Our testing methods are in accordance GLP protocols and utilize equipment that is traceable to NIST standards. Copies of actual test result are available upon request. Syringe use: - eliminate the carry over between the samples. Rinse the syringe with the to be examined liquid 10-20 times. Wash the syringe and discard the first 2 -3 washes. - for injection overfill the microlitersyringe. Press the plunger until the accurate volume. Syringe cleaning - pull the piston out of the glass body of the microsyringe - rinse inside the glass body with detergents (in the final rinsing cycle it is best to use a low boiling point, solvent or alcohol) - dry the glass body by air flow, e.g. with a vacuum pump CAUTION: DO NOT IMMERSE THE MICROSYRINGE IN THE SOLVENT: THE GLUE PARTS CAN BE SOLVED. Needle blocked: - use the cleaning wires from ILS you find a wide range at www.microsyringes.com Plunger with seal - if you want reduce the plunger force, heat the assembled syringe in oven at 60°C 15 minutes - Silicone or other lubricants that are compatible with your sample may also be used to wet the plunger tips CAUTION: RUNNING A TEFLON-TIPPED PLUNGER DRY MAY CAUSE THE PTFE TO SHRED OR PULL LOOSE FROM THE PLUNGER ROD, RESULTING IN LEAKS. Plunger Tip ss*=stainless steel (N- Series) -clean the plunger in an ultra sonic bath - wipe the piston with a fibre-free cloth (i.e. no paper towel) Plunger of zero dead volume syringes (T- Series) - loose the nut before pull out or insert the plunger - wipe the piston with a fibre-free cloth (i.e. not paper towel)
