The MESTRA hydraulic laboratory press is sturdy and pleasing to the eye. It is simple and easy to handle, and the latest trends in new materials have been applied to its construction. Its oil-hydraulic system is designed so that the oil cannot escape from the chamber. All parts subject to wear are made of ground hardened and tempered steel and finished with epoxy paint. The MESTRA press includes bottom plate recovery springs which enable it to be always in a usable position. The top plate diameter and the width between columns enable flask(s) to be inserted and removed with the MESTRA R-030380, press flange, without having to raise or lower the spindle, thus saving time and trouble.
