Large Sample Rowe Cell 252.3 mm (10”)

Large Sample Rowe Cell 252.3 mm (10”)

Mar 31 2014


VJ Tech has recently developed a Rowe Consolidation Cell suitable for a 252.3 mm (10”) sample. The Rowe cell is a development of the original cell designed by Professor P W Rowe at Manchester University, England. The cell is precision made specifically for soil testing laboratories and there are other Rowe Cells available to suit a number of specimen sizes. They are capable of withstanding varying confining pressures up to 1750 kPa (dependent on the sample diameter) and are designed with specially coated material to minimise corrosion. VJ Tech’s csRowe Software enables test set up, control, live data viewing during the test and exportable results.

The VJ Tech Rowe Cell Testing System utilises a hydraulic APC to apply vertical load to the sample contained in the cell. The advantage of this type of cell is that drainage can be precisely controlled. In addition, the hydraulic loading system gives accurate control of applied loads over a wide range, including high pressures on large diameter samples.

Main Advantages

·     Large sample diameter
