This Vial Stand offers space for six round cuvettes with a diameter of 24 mm
While in the stand, the vials are safely stored and cannot slip or tip over - it's the perfect assistant for smooth test procedures!
Thanks to the transparent acrylic, users always have an unobstructed view of sample development and color changes.
The programme of exercises enables familiarisation with six different drive implementation and analysis methods: understanding the brief and the drawing, assembly, setting, adjusting, testing, and making calculations. This laboratory system is used to introduce combined drives and their correct assembly. A robust tubular steel frame with a square profile and bearing elements provide the accuracy for the setting of precise gearing. The flexibility of the set-up and the modularity of the components simplifies experimentation and implementation of the students' own ideas. All the system components are kept ready to hand and well protected in a housing system.

The Piping Learning System teaches how to layout and assemble fluid piping systems used in industrial, construction, agricultural, and transportation applications. The Piping Learning System Piping Technology learning system includes a mobile workstation, pump testing network, valve package, fitting package, fitting identification kits, Sloan valve maintenance kit, pipe insulation and hanger components, fitting storage, student learning materials for both theory and lab, and teachers guide. The workstation has slotted, movable members to enable a variety of hydraulic hose fluid piping application scenarios to be set up. Students will learn how to select, size, identify, and install a variety of types of industrial fluid piping, fittings and valves including: iron pipe, steel tubing, hydraulic hose, plastic pipe, copper tubing, globe valves, gate valves, check valves, and Sloan valves.
Features:
Built-in Pump Leak Test System
Built-in Storage
Mobile Workstation
Moveable Members.
The instructional material includes a complete set of drawings. The geometric models support the learning process by providing an introduction to technical drawings: from the solid model to the more abstract representation of the three views in a technical drawing. It presents each model in three views, as well as its 3D view and production drawing. The set contains 18 aluminium drawing models. The prismatic models have cut-outs parallel to, and at an angle to, the edges of the prisms. The models are precision-manufactured and are suitable for measurement exercises as well as drawing exercises.

The flexibility of a CVT with suitable control may allow the input shaft tomaintain a constant angular velocity even as the output speed varies. Acontinuously variable transmission (CVT), also known as a single-speedtransmission, stepless transmission, pulley transmission, or, in case ofmotorcycles, a twist-and-go, is an automatic transmission that can changeseamlessly through a continuous range of effective gear ratios. This contrast swith other mechanical transmissions that offer a fixed number of gear ratios.
The completepower flow within the CVT automatic transmission can be observed:
Primary andsecondary conical disk with hydraulic piston
Idler gearand differential
Input shaft
Planetarygear with hydraulic clutch mechanism
Speed changeby movement of the conical disks.
All the power and instruments used in the experiments have reliable protection. At the same time it set up a reliable safety protection system. Its superior performance is the best choice of the major colleges laboratory construction. The experimental device absorbs the advantages of domestic and foreign advanced teaching equipment. It uses hanging box. All experimental instruments have the digital display. It takes full account of the laboratory's current status and future trends and makes the innovation in performance and structure.
Applications:
It is applicable to major colleges experiment teaching like electrician basis, electrical engineering, digital circuit, mode voltage, motor learning, motor and power drag, motor control, relay contactor control. Also the programmable controller experiment, the motor inverter control experiment and so on can be expanded.
Analogic Strain Gauge 300 MM Length instrument can also be used for other structures like steel and wood. Strain gauge, 300 mm. measuring length.
Different models are available with analogic or digital gauge, 100, 200, 300 mm measuring length, depending on the standard length to be measured. Analogic Strain Gauge 300 MM Length Used to determine the strain (length changes) in concrete specimens and structures, rock strata, different parts of a structure, in remote areas and under adverse conditions, using a single instrument.
Application:
Operation of an open loop and closed loop system
Characteristics of an encoder.
The floor mounting frame can be easily converted to a bench-mounted version when using the bench mounting feet arrangement which is supplied as standard. The internal working dimensions for mounting experiments are 1.22m x 0.76m. Manufactured from high quality, ergonomic aluminium profile, the Universal Frame and Stand comprises an upper dual frame, which creates a continuous mounting slot around all four sides of the frame thus allowing the individual experiment components to be interchanged quickly. Should specimen beams longer than 1.22metres be used, the working gap allows the beams to run through the frame and protrude outside the working area.
