Description

Black-and-white photograph of a 200-ton press in the Machine Room of Johnston Laboratories at the University of Liverpool, Liverpool, England, in the United Kingdom. This photograph dates from the formal opening of the laboratories in 1903.

"A large room has been fitted in the Thompson Yates laboratories with apparatus for the use of the various research departments. Shafting running the length of the room is driven by a 10 horse-power motor, and from the shaft is driven an hydraulic press giving a total pressure of 200 tons, a high-pressure filtering apparatus, and gas liquefier, and a powerful centrifuge. From a smaller motor and shafting is driven a large centrifuge, a vaccine mill, a bacterial mill and disintegrating apparatus. The shafting is so constructed that new apparatus can be added as occasion requires."
