VWR Vwr Bubble Mat 4x8 Gray Unit EA. The mats feature a unique built-in "self-inflating" feature. When the pump is turned on the air in the mat equalizes the pressure and causes the mat to float. Unlike other mats this causes any powdered residue on the mat to fall away. This will effect the chemical composition of any solution that the mat comes in contact with. Therefore this mat must be inflated with a liquid before use or the like. The mat is great for containing leaky gas analyzers and sensor pads because the trapped vapour will be trapped in the microscopic pores formed within the mat. Most importantly the mats cushion the hand from the heat and pressure changes that may occur while scrubbing with a buffer. This provides a cushioned surface that protects hands from heat reduces noise and isolates droplets or powders that may be carried within the lab.
