Furthermore, the standard emulsion contained the maximum amount of fungi and yeasts detectable with these dip slides. The ATP content of the standard emulsion corresponded to 2,300,000 RLE (relative light units).
• the lubricant according to embodiment 35 contained as Additive 1-phenyl-1-propanol, while in the embodiment 37 was included as an additive 1-phenyl-2-propanol.
• the respective lubricant was used immediately after manufacture visually assessed. It should be noted that the lubricants at a lubricant temperature of 50 ° C 34 and 36 showed phase separation while the lubricants 35 and 37 formed a homogeneous, clear liquid.
• the lubricants were at a lubricant temperature of 20 ° C 34 and 36 cloudy, while lubricants 35 and 37 remained clear.
• the lubricants were at a lubricant temperature of 0 ° C 34 and 36 still cloudy while the lubricants 35 and 37 remained clear.
• the lubricant according to embodiment 39 contained as Additive 1-phenyl-1-propanol, while in the embodiment 41 was included as an additive 1-phenyl-2-propanol.
• the respective lubricant was used immediately after manufacture visually assessed. It should be noted that the lubricants at a lubricant temperature of 50 ° C 38 and 40 showed a phase separation while the lubricants 39 and 41 formed a homogeneous, clear liquid.
• the lubricants were at a lubricant temperature of 20 ° C 38 and 40 cloudy, while the lubricants 39 and 41 remained clear.
