The Wig-L-Bug is an invaluable accessory for the spectroscopy laboratory. It is ideal for mixing and pulverizing samples for use in a KBr matrix that will be pressed into a pellet and for mulling techniques. Sample preparation is reproducible from sample to sample by replicating the cycle time, which is controlled by a 60 second timer. Most samples can be prepared in 10 seconds. Agate, metal and plastic sample vials are available. 115 volts only.
