The steam bench includes a water-cooled multi-tube condenser; a steam feed line to supply a regulated supply of steam at reduced pressure and a condensate tank complete with a sight glass. Cooling water flow rate is metered in the supply line and regulated by a control valve in the drain line. Steam Bench Consists of a sturdy framework and panels of all steel construction, fitted with a student work surface, interconnecting back panel and adjustable feet. Bourdon type pressure gauges are provided from pressure indications and thermocouples are used to measure temperature, which may be individually selected for display on an analogue temperature meter.
Features:
Compact modular design
Easy Installation
Comprehensive instrumentation
Low capital cost
Pressure test certificates supplied for major components engine
Utilises industrial standard horizontal shell and tube type condenser.
The steam bench incorporates four similar mild steel tubes, each connected to a common steam supply via an inlet regulating valve and a common blowdown line via an outlet valve. Two of the tubes are unlagged but have differing finishes, namely a painted finish and a chromium plated finish respectively. Lagging Efficiency Steam Bench consists of a sturdy framework and panels of all steel construction, fitted with a student work surface, interconnecting back panel and adjustable feet. The measured temperatures are displayed on an analogue temperature meter via a selection switch. From measurements of temperature and condensate levels over a period of time, students are able to calculate the lagging efficiency and the coefficient of thermal conductivity of the lagging. The remaining two tubes are lagged, one with glass fibre webbing tape and the other with a pre-formed fibre glass insulation jacket. Each tube is fitted with a sight glass and scale to enable condensate to be measured.
Features:
Pressure test certificates supplied for major components
Easy installation
Comprehensive instrumentation
Dividing panels so radiation does not affect thermocouple readings
Compact modular design
Low capital cost.
Vertical Autoclave Steam Sterilizer

Large steam sterilizers are used for bulk sterilization processing and are typically found in the hospital's central supply department. Most operating suites and labour and delivery areas are equipped with smaller units for their own routine needs; however, areas that perform a great deal of sterilization may require large sterilizers.
Large steam sterilizer (autoclave) designed as tabletop model with a capacity of 80 litre featuring a front-loading door, suitable for bulk sterilization of wrapped, unwrapped, solid and hollow items as well as porous loads such as drapes and gowns. Electrically powered, requires a single-phase power grid supplying 230 volt, 50/60Hz, 7.4 kW.
Steam sterilization kills microbes effectively and is often viewed as the gold standard of healthcare sterilization methods. Typical items to be sterilized include surgical instrument packs, surgical implants, irrigation fluids, devices intended for and used by patients in isolation, and obstetric and dental instruments. Steam sterilizers use pressurized steam to generate moist heat to eliminate viable microbes from non-heat-sensitive medical devices, including heat-tolerant products used for surgical and general patient care.
Includes a type 1 steam sterilizer indicator which is designed to indicate exposure to steam, but not designed to verify either the correct functioning of an autoclave or whether items have been properly sterilized. Used to close paper crepe packs for steam sterilization. Easy released pressure sensitive adhesive, easy to tear paper, easy to remove.

The basic plant generates steam by means of a boiler, uses it by means of an action turbine and, finally, condenses and recovers it. The plant includes units for supplying water and fuel, an electrical board for controls and commands, and the instruments needed for performing the basic tests. Plants for the generation and utilization of water steam are particularly important for purposes because due to their complexity they are of interest to various training fields such as thermodynamics, electro technics, mechanics, plant design and others. Technology and use of steam plants. The installation is also very simple stonework is not required only the electrical power supply and water supply from the normal distribution networks. Some optional kits are provided to increase the number of ways to use the plant and run further tests. The optional kits and the system are described on separate sheets. The system is supplied complete with manuals describing the system in all its parts, the procedures for installation and use. A data acquisition and analysis system for Personal Computers is available to monitor the principal parameters of the plant in real time, take measurements by means of a Personal Computer, produce characteristic curves of various components, and store test data on disc or print them out.
