Nitrile Exam Gloves are reliable, easy-to-wear gloves that are more economical than standard nitrile gloves, and are suited for a wide variety of tasks.
The nitrile gloves deliver enhanced dexterity, thanks to textured fingertips, and are not made with natural rubber latex.
Nitrile Gloves can be an important piece for creating a more efficient, responsible workplace.
The gloves are static dissipative in use. They come in an innovative dispenser box, which incorporates two separate openings.
The first, smaller opening is used when the box is full and helps control dispensing to lessen waste from dropped gloves or multiple dispensing.
When the box is half empty, the second, larger opening allows easier access to the gloves. They have an 1.5 for pinholes and can even be recycled with the Kimberly-Clark Professional RightCycle program, the first large-scale recycling program for nonhazardous lab and cleanroom waste.
Exceptional value: 250% more gloves per case (versus standard nitrile gloves)
Waste less with the one-at-a-time dispenser box; Element Nitrile Gloves are recyclable through the Right Cycle program.
Not made with natural rubber latex, are powder -free and feature beaded cuffs
Superior quality.

The Computerized Refrigeration Study Unit With Mass Energy Balance is an extremely easy-to-use and functional unit able to permit the study of a compression frigorific cycle and the evaluation of the cycle efficiency and the energy balance at the evaporator and at the condenser. A front panel with mimic diagram and instrumentation allows to keep the most significant thermodynamic quantities under control, so facilitating the students understanding and the teachers task. The unit is supplied with manuals which describe the components, the installation and utilization procedures as well as many exercises with experimental results. Moreover, the transducers and the dedicated software allows the data acquisition of the main thermodynamic quantities and to obtain or as a table or as a graph, the acquired values and the thermodynamic calculated quantities. The unit allow the study of the main thermodynamics quantities as a function of the thermal load at the evaporator and the calculation of the power required at the compressor shaft.

This instructional kit provides the necessary material for students to learn systematically how a hub and a shaft can be joined together in a professional way using feather keys. The material is clearly laid out on a plastic tray. The well-structured instructional material outlines all the necessary technical information and provides a step-by-step guide through the exercises. We recommend that the exercises are carried out in a workshop, as all preparations such as filing, drilling, countersinking and tapping must be carried out in a correct and proper manner by the student.

The deflection of a spring depends on the load applied to it, an observation enshrined in Hooke's Law Applications of springs are found in spring balances which indicate loads by measuring spring deflections and in car suspensions where they absorb energy caused by wheel vertical movement due to potholes and bumps. Compression of Springs Apparatus are used in engineering to store energy or to provide restoring forces. Both compression and tension springs may be encountered.
Experimental Capabilitis:
Using the optionally available compressive spring set the dependence of spring stiffness on the wire diameter, spring diameter, length, number of turns and material can be observed and calculated
