The specimens were stretched in a floor model Instron between 2-inch wide grips at a crosshead rate of 0.5 inch/min. Temperature was 23 it 1°C, but humidity was not controlled. Proper alignment was very important for the wide specimens.

Some floor-model fryers have built-in filters. These filters are made of stainless steel mesh. Usually, a layer of filter paper is used on the screen. A built-in pump circulates the oil through the screen for several minutes. The filtered oil is used to flush the residual solids in the fryer pan, and the filtered oil is put back in the fryer pan and stored until the next operation. The oil is filtered at least once every day. For some products, it is necessary to filter the fryer oil twice or three times daily because of the heavy accumulation of crumbs.

Most reach-in chambers are floor models that range in size up to 33 cubic feet and larger. These typically have up to 10 adjustable shelves. The system mechanics (compressor, coils, control circuitry, etc.) are built into the chamber cabinet. Reach-in chambers are less expensive initially and are used when the number of samples is relatively small or when the conditions are likely to be changed. There is less potential risk with the failure of a reach-in chamber since the number of samples is likely to be fewer than in a walk-in and it would be easier to transfer the samples to an alternate chamber. 

Another possibility is to ask for a floor model of a particular high-priced piece of equipment. The floor models are often used for demonstration purposes or at conferences. Because they have been slightly used, a vendor can often sell such equipment to the safety and loss prevention professional at a reduced cost. However, you have to ask. 

Commercial XRF systems include WDXRF and EDXRF laboratory-based instruments from floor models to benchtop systems, handheld X-ray analyzers based on EDXRF, field-portable XRF systems, andmicro-XRF systems. Commercial XRD systems include single-crystal diffractometers.

Centrifuges (benchtop and floor models, cooled if possible). 

Higher force tabletop or floor models these most frequently are load frame instruments with capacities up to 450 N (or possibly greater)... 

Low-force tabletop instruments are offered by the traditional thermal analysis vendors Mettler Toledo, Netzsch, Perkin-Elmer, and TA Instruments as well as Seiko Instruments. Higher-force tabletop and floor model instruments are offered by Bose and OldbMetrovib. Rotational rheometers that also perform torsional shear measurements on solid samples are marketed by Reologica... 

In addition, Metravib offers the DMA -i-100, DMA -i-150, and DMA + 450, which are larger floor-model instruments that have very rigid frames and exhibit extended ranges of measurable stiffness and frequency.

The dynamic shear testing of rubber-to-metal bonds was done with a Plastechon Universal tester. This machine is an electro-hydraulic floor model with a 20,000-lb capacity. (Fig. 1.) It has additional interchangeable actuator/piston sleeve assemblies available in 2,500, 5,000 and 10,000-lb capacities. The speed range of the tester varies with the capacity. The range under 20,000-lb actuator service is from 2.0-3000 in/min, with speed range being...
