The Shanadilya brand haemometer housing is moulded from thermo-setting phenol formaldehyde resin which makes it resistant to most laboratory reagents. It is also very convenient to handle, light in weight, and gives unlimited service. The permanent non-fading colour standards are made with optical precision for accurate and exact matching of colour. They are comparable with international master colour standards of hemoglobin values. They never fade or get discoloured.
