A binocular laboratory microscope with a measuring single tube inclined at 45 degrees and rotating through 360 degrees, with interpupillary distance adjustable from 48 mm to 75 mm. It is supplied with WF10X and WF16X eyepieces and a four position achromatic objective set of 4X, 10X, 40X and 100X. The double layer mechanical stage measures 140 x 130 mm with a 70 x 50 mm moving range, over an N.A. 1.25 Abbe condenser with iris diaphragm. Coaxial coarse and fine focusing runs on a rack and pinion mechanism with a fine focusing scale value of 0.002 mm, lit by a built-in 6V 20W variable brightness lamp. GEMMY publishes no product name for this model, only the model number PB-3320.
A micro haematocrit centrifuge for packed cell volume work, used in biochemistry, microbial immunity genetics, blood separation and general clinical testing to establish the percentage of red blood cells against whole blood, which can indicate anaemia or polycythaemia. GEMMY states that all models in the range run at a fixed 12000 rpm apart from the PLC-012 and PLC-012E. The time is set and the run started with the START button, the rotor lid must be closed before spinning, and a reading scale is supplied so the capillary tube can be read directly. EPDM is used for the rotor gasket to extend service life, and a safety device cuts the power if the lid is opened during operation.
A binocular microscope whose measuring single tube is inclined at 30 degrees rather than the 45 degrees of the rest of the PB range, rotating through 360 degrees with interpupillary distance from 48 mm to 75 mm. WF10X and WF16X eyepieces pair with achromatic objectives of 4X, 10X, 40X and 100X. The double layer mechanical stage measures 135 x 125 mm with a 70 x 50 mm moving range, over an N.A. 1.25 Abbe condenser with iris diaphragm. Focusing is coaxial coarse and fine on a rack and pinion mechanism with a fine focusing scale value of 0.002 mm, and illumination is a built-in 6V 20W variable brightness source.
