The Cement Autoclave provides an accelerated means of estimating delayed expansion of Portland cement caused by hydration of CaO, MgO, or both in accordance with procedures described in ASTM C151. In this operation, changes in length of test bars of cement are measured after being exposed to controlled steam pressure and temperature for a prescribed period of time. The Boekel cement autoclave is ASME certified and is the leader in expansion testing apparatus.

The Cement Autoclave consists of a welded ASME certified steel cylinder with a bolted cover mounted on a sturdy supporting frame and enclosed in a heat insulated metal housing. The unit is designed to handle pressure in the 60-350 psi (0.4 -2.4 MPa) range and consists of steam vessel, pressure regulator, pressure gauge (0-600psi), air vent valve, power switches, and a safety pop valve set at 350 psi. All components are pressure tested and designed to meet the highest safety standards.

Histology Overview 

Histology Laboratories specialize in the microscopic study of cells and tissues of plants and animals.  Labs that focus on the microscopic  study of diseased tissue are referred to as histopathology laboratories.   Histology requires specialized equipment for preserving and preparing samples for viewing under a microscope.  The process typically follows the same routine:

Grossing and Fixation – Tissue samples are taken and trimmed to the proper size.  These samples are then placed into solutions to preserve the sample.

Processing – Water is removed from the sample and replaced with melted paraffin wax.  The wax solidifies and maintains the tissue structure

Embedding – The tissue is placed in a larger block of wax so that it can be cut properly.

Sectioning – The paraffin block with tissue is placed into a microtome.  The microtome slices sections of the tissue into a ribbon.  This ribbon is then placed into a water bath so it can be placed on a slide.

Staining – Depending on the tissue type the sample needs to be stained so that the structures and items of interest can be viewed in a microscope.  Molecular probes can be used to detect cancer, genetic anomalies, and bacteria or viral infections.

Viewing – The sample is views under a microscope.

Storing –  Many samples require long term storage.  Specially designed cabinets are used to store vast quantities of slides and cassettes.
