Setting the Humidity Conditions
If humidification is required, the humidity tray which is located on the lower shelf runners
should be pulled forward and filled with 0.5 litres of warm distilled water for cell culture work –
we recommend the use of copper sulphate (or recognised biocide) in the humidity tray. Tests
have shown that as well as inhibiting bacterial growth in the tray this can reduce
contamination on the chamber walls (one small teaspoonful copper sulphate recommended).
For IVF and other sensitive work – we do not recommend the use of any biocide in the
humidity tray. To reduce the possibility of contamination, the humidity tray water should be
changed and the humidity tray cleaned with 70% Alcohol / 30% distilled water solution every
10 – 14 days. To remove / replace the humidity tray: - turn the tray through 45° and remove
for refilling.
DO NOT LEAVE WATER IN THE HUMIDITY TRAY IF THE INCUBATOR IS SWITCHED OFF , AS
THIS MAY RESULT IN DAMAGE TO THE CO
