Operating Limitations
● Chlorinated and fluorinated hydrocarbons or chemical combinations which form depostis
may make it difficult for the piston to move or jam it. If the piston becomes too diffcult to move,
immediately clean the instrument.
● While dispensing inflammable fluids, avoid the built up of static charge. Make sure that you do
not dispense into plastic vessels and do not wipe instruments with a dry cloth.
● E-BURETTE is designed for general laboratory applications and complies with relevant
standards, like DIN EN ISO 8655-3. Please check the compatibility of the instrument for a
specific application (e.g. trace material analysis, food sector etc.). Approvals for specific
applications, like production and administration of food, pharmaceuticals and cosmetics are
not available.
Operating Exclusions
Do not use the instrument with:
● Liquids that attack FEP, PFA and PTFE (e.g. dissolved Sodium Azide*).
● Liquids that attack borosilicate glass (e.g. Hydrofluoric acid).
● Hydrochloric acid > 40% | Tetrahydrofuran or Oxolane | Trifluoroacetic acid.
● Explosive liquids (e.g. Carbon Disulfide).
● Suspensions (e.g. of charcoal) as the solid particles may clog or damage the instrument.
● Liquids that attack PP (cap).
● An aggressive atmosphere, e.g. HCl fumes.
* The permissible concentration of dissolved Sodium Azide is not more than 0.1%.
Storage Conditions
Store the instrument and accessories in a clean, cool and dry place. Storage temperature
from –20 °C to +50 °C (from –4 °F to 122 °F) is advised with relative humidity between 5%
and 95%.
