Adjustable stem for locking plate.
Compact Dry E. coli/Coliform Count (EC) is a Direct Culture based ready-to-use test method for Rapid Enumeration of Escherichia coli and coliform bacteria.
Compact Dry E. coli/Coliform Count (EC) plates for bacteriological testing of drinking water.
The medium should be rehydrated with 1mL diluted sample inoculated onto the center of the self-diffusible medium, allowing the solution to diffuse by capillary action. The plate can be incubated at 35[degrees]C for 20-24h and the colonies counted without any further working steps.
The plates are pre-sterilized, contain culture medium and a cold water-soluble gelling agent
Medium contains 2 kinds of chromogenic enzyme substrates that develop red/pink color for Coliform and white/blue color for E.coli.
Storage: Keep at room temperature (1-30 degrees C). Refrigerated storage is not required.

The panel has a thin sheet metal absorber backed by riser tubes and insulating material to reduce heat loss to the rear. The collector has a purpose designed and built panel for quality and reliability. A sturdy mobile frame supports the collector. To allow users to adjust its angle, the frame has a hinge. A box with a clear cover encloses the panel, forming the collector.
It allows students to measure and find the efficiency and heat losses of a flat plate solar energy collector. This equipment shows how a flat plate solar energy collector works.
Demonstrate and study boundary layers and boundary layer growth with ease. The pressure probes ascend on an angle covering a width of one inch (25.4mm) and a height of 0.24 inches (6.1mm). The probes are approximately 0.048 inches (1.22mm) apart along the diagonal. The Flat Plate And Mouse combination has a 10-tap total pressure probe, or mouse, that can be positioned in three locations along the length of the flat plate.

The Ball and Plate Apparatus shows the problems of the of an unstable system. The apparatus consists of a plate pivoted at its centre so the plate can tilt in two directions.
The basic control task is to control the ball position. The ball is free to roll on the plate.
Stepper motors tilt the plate. A servo system with a stepper motor control card controls the motors. A camera with an intelligent vision system measures the ball position.
The equipment includes:
A data acquisition board for your computer
Camera with USB connection
Ball and plate model
Power supply
The data acquisition board fits into a suitable computer (not included) to link with the Ball and Plate Apparatus and control its motors.
Software (included)
Interface library for programming at the system level
Demonstration program with PID controllers

This experimental unit forms part of a series of teaching systems developed in collaboration with the Department of Automation and Information Technology at the Harz University of Applied Studies and Research. A fuzzy control is used to move the ball to a specific position quickly and with as little movement of the plate as possible, even when the position of the ball is modified by external influences. A ball-plate model acts as a weakly-coupled mechanical multivariable system. The inclination of the plate is modified by the movements of the respective motors; these movements are transferred to the plate by the drive rod. A joystick can be used to control the system manually. This allows the degree of difficulty of the control process to be estimated very accurately. The position of the ball is measured without feedback using a touch panel and the crisp signals sent to the fuzzy controller, where the signals are transformed into fuzzy input values and inferenced before being transformed back into a crisp output value. Two servo motors act as actuators during this process.

The plate fits in a location below the main accessory aperture and allows the velocity profile behind all of the optional heat exchangers to be investigated. Also supplied is an upstream pitot tube that can be traversed across the duct to investigate the upstream velocity profile. The Pitot Static Traverse Plate includes a sliding plate, and pitot tube with multiple locations designed to be traversed across the duct of the base unit.
