Resistance of the vacuum chamber
When the following chemicals are evaporated, there is a risk of erosive surface corrosion, pitting, crevice corrosion
or stress corrosion cracking according to our chrome steel supplier Nirosta®. This may lead to vacuum leakage.
Aluminium chloride (AlCl3 * 6H2O), ammonium bifluoride (NH4HF2), ammonium chloride (NH4Cl), aniline
hydrochloride (C6H5NH2HCl), antimony trichloride (SbCl3)
barium chloride (BaCl2 *2H2O), blood (in the presence of salt, pitting corrosion and crevice corrosion may
occur, particularly with porcine blood), bromine (Br2), bromine water
calcium chloride (CaCl2 * 6H2O), calcium hypochloride (Ca(OCl)2 * 4H2O), chlorine (Cl2), chlorinated lime
((3CaCl(OCl) * Ca(OH)2) * 5H2O), chloric acid (HClO3), chlorosulfuric acid (HSO3Cl), chlorine water, hydrogen
chloride gas (HCl)
iron (III) chloride (FeCl3), iron gall ink (inks containing salt may cause pitting corrosion and crevice corrosion)
hydrofluoric acid (HF)
mine water
urine
iodine (J2), iodine tincture
potassium bifluoride (KHF2), potassium bromide (KBr), potassium chloride (KCl), potassium hypochloride (KClO),
aqua regia (HCl + HNO3), copper (II) chloride (CuCl2 * 2H2O)
magnesium chloride (MgCl2 * 6H2O), monochloroacetic acid (CH2ClCOOH)
sodium chloride (NaCl), sodium chlorite (NaClO2), sodium hypochlorite (NaClO)
nickel chloride (NiCl2 * 6H2O)
photographic fixing bath, brine solution, pink salt ((NH4)2(SnCl6))
mercury (II) chloride (HgCl2)
hydrochloric acid (HCl), pickled cabbage brine, sulphuric acid (H2SO4), seawater, mustard, silver bromide
(AgBr), silver chloride (AgCl)
toluene sulfonic chloramide sodium (CH3C6H4SO2NClNa * 3H2O), trichloroacetic acid (CCl3COOH)
water, acidic (mine water, dependent on chloride concentration), zinc chloride (ZnCl2), tin (IV) chloride (SnCl4),
tin ammonium hexachloride
When evaporating the aforementioned solvents using the DancerPlus, we recommend thoroughly
cleaning the vacuum chamber and rinsing it daily.
This includes the tube connection system for the vacuum pump and, if required, for the cold trap,
as well as the cold trap chamber.
