PureAClean blue, non-marking, NON ESD SAFE 1/2" (12.7mm) diameter vacuum cup. The vacuum cup material is PureAClean, a catalytically cured silicone based rubber compound. This cup material is ideally suited for handling residue sensitive items such as lenses or optical filters.
Operating temperature limits (-65oF - 480oF) (-55oC - 250oC).
Electrical properties: Greater than 1013 Ohms.
Lifting capacity at 6 In Hg: 250 g (8.8 oz)
Lifting force is directly proportional to the vacuum level and the surface area of the vacuum cup being used .
