The ergonomic, compact design ensures comfortable operation during prolonged observation periods. Equipped with a quadruple nosepiece and a full suite of Plan C Achromat objectives (4x, 10x, 40x, 100x Oil), the CX21 provides versatile magnification capabilities suitable for cytology, hematology, and general biological microscopy.

Condition Notes

Condition: Used / Inspected This instrument has been fully inspected and tested for functionality. The mechanical stage operates smoothly across both the X and Y axes, and the coarse/fine focus mechanisms are responsive without binding. Transmitted illumination is fully operational with adjustable light intensity. The optics (eyepieces and objectives) are clear and free of major defects that would impede observation. Cosmetically, the unit is in good condition with minor, superficial wear typical of standard laboratory use.
