Zeiss ra routine research microscope instructionsSTANDARD RA Routine and Research Microscope Operating InstructionsUnpacking The STANDARD RA microscope is supplied in a Styropor case containing tightly fitting compart- ments for the stand and the different components of the instrument. Ideal as this type of packing is for transportation. the microscope should not be stored in this case for prolonged periods. since the unavoidable humidity of the air will be trapped in the perfectly sealed case and may attack the instrument. The Styropor case should. however. be kept for shipping purposes. Before starting to assemble the instrument, please check the consignment for completeness with the aid of the packing slip.
