Page 13: About The Documentation
1 Introduction This instrument is suitable for processing chemicals and flammable sam- ples. Usage of the 855 Robotic Titrosampler therefore requires the user to have basic knowledge and experience in handling toxic and caustic sub- stances. Knowledge with respect to the application of the fire prevention measures prescribed for laboratories is also mandatory. -
Page 14: Safety Instructions
The electrical safety when working with the instrument is ensured as part of the international standard IEC 61010. WARNING Only personnel qualified by Metrohm are authorized to carry out service work on electronic components. WARNING Never open the housing of the instrument. The instrument could be damaged by this. -
Page 15: Tubing And Capillary Connections
Personnel safety WARNING Wear protective goggles and working clothes suitable for laboratory work while operating the 855 Robotic Titrosampler. It is also advisable to wear gloves when caustic liquids are used or in situations where glass vessels could break. ￭￭￭￭￭￭￭￭... - Page 16 Always install the safety shield supplied with the equipment before using the instrument for the first time. Pre-installed safety shields are not allowed to be removed. The 855 Robotic Titrosampler may not be operated without a safety shield! WARNING Personnel are not permitted to reach into the working area of the instrument while operations are running! A considerable risk of injury exists for the user.
