Annualy
Replace burette stand, 1, 5, 10, 25, 50 ml and the anti-diffusion tip, part. no.956-309.
Frequent use or use with aggressive or concentrated reagents occurring crystallisation risks
may severely reduce the burette and anti-diffusion tip lifetime and may consequently
require to replace them more frequently.
Replace burette stand set of 3 tubing, (stands 5, 10, 25, 50 ml, part number X31T115
and stand 1 ml, part number X31T116).
Replace damaged burette accessories: bottle stopper, desiccant tubing.
Contact your Radiometer Analytical representative for instrument revision and cleaning.
Recommendations of use
After installing new burette and/or tubing, before use, check that all tubing fittings are
sufficiently tightened to prevent leakage, and that no tubings are crimped (do not over
tight fittings)
The reagent should be at room temperature before use in the burette.
Do not leave burette installed with concentrated base, acid or salt solutions. Always rinse
after use, at least daily, to increase stopcock and burette lifetime.
Organic solvents: the organic solvents given as reacting with and/or destroying the
VITON® (Fluorinated polymer) should not be used with our burette stands (example:
TetraHydroFurane). The solvents given as simply making inflate the VITON® are allowed.
Please contact us if you wish to work with solvents destroying the VITON®.
