laboratory drying racks. ;Stainless steel laboratory drying rack Stainless steel laboratory drying rack, which is also known as a 'Mod-Rack' pegboard, is the drying rack made of stainless steel that uses to drain laboratory accessories. The examples of stainless steel laboratory drying rack are flask holders, soap dispensers, paper towel dispensers, glove box holders, drain shelves. Stainless steel pegboard installation is very easy and quick to set up with basic hand equipment's, and it does not damage the wall as mounting brackets and hardware are being used. ;Epoxy laboratory drying rack Epoxy laboratory drying racks are the most common type of drying rack that are used among university labs and science classrooms in many high schools. Epoxy drying racks are mounted directly to a wall or other solid structures which can be set up with basic hand tools and power tools. They are easily installed by using wall anchors and other strong fasteners due to their small weight. Typical installation is to drill holes, one at each corner, and to use the mounting points in order to fix it to the wall. ; Acrylic laboratory drying rack Acrylic laboratory drying racks give a unique feature that other pegboards cannot do. The clear acrylic is transparent, which means that it allows the light to pass through as well as brightening the working area. Acrylic pegboards are mostly in the place where there are no lights, or to be done in dim areas. Like epoxy pegboards, acrylic laboratory pegboards are also installed with basic tools and power tools in the same way. However, acrylic pegboards are made up of plastic, so it can be easily scratched as compared to the epoxy and the stainless steel drying rack.
