THE SUPPLIER OF THESE TROLLEYS HAS NOW DISCONTINUED THEM, AND REPLACED THEM WITH A RANGE WHICH WE FEEL IS INFERIOR. WE ARE CURRENTLY LOOKING TO SOURCE ALTERNATIVES WHICH HAVE THE SAME OR VERY SIMILAR SPECIFICATIONS.These trolleys are chemical resistant and are used in research, medical, industrial and education labs all over the world. All trolleys are extremely lightweight, have a safe working load of 250kg and are supplied with precision bearing castors including 2 brakes. These Lab trolleys are ergonomic in design and attractive in appearance. The construction of the trolleys is from the highest quality, nylon fibre blended polymers which are resistant to the harshest working conditions. The Lab trolley also includes a rubber construction mallet for easy assembly. Please note that the dimensions given are for the overall size of the trolleys, i.e. they include the wheels and handles.
