Condenser top

The base and top of condenser 0.30 S70 form a self-contained unit (Fig. 6).

The condenser top 0.30 S70 (13.4) cannot be used with the condenser base (8.1).

The condenser top 0.53 S23 (8.2 and 9.1) is screwed straight on to the condenser base (8.1). A spacer ring (9.4 and 11.3) must be used for assembling the condenser tops 0.90 S1 and P 1.40 OIL S1 (9.2 and 9.3).

Adjust the height of the condenser until its upper edge is flush with the condenser height marking S70 on the illumi- nation column. Secure the condenser with the supplied hexagonal screwdriver. Erect the TL illumination column.
