Keeping Count: Sanborn/Frommer Model 75
Date: early 1960s
HP’s Sanborn/Frommer Model 75 electronically counted the red and white blood cells in samples, offering researchers and medical staff a faster, easier and more accurate method than manual counts. Designed as a compact bench-top unit, the 75 could withstand everyday use in a busy laboratory. Initial testing found that the device could sample 50 times the number of cells sampled in a manual count and that the electronic counting method provided greater accuracy.
