Measure Curing Time with Ease

The GT-300 Plus Gel Timer offers an easier way to test the curing time of products such as epoxies, polymers, adhesives, paints, and sealants

The process of curing often makes the spindles and sample holders.difficult or impossible to clean. Withe the GT-300, spindles, sample cups, and even the temperature probe are disposable, which means you never have to worry about clean-up problems. 

Temperature control options allow for testing products that need to cure at higher (up to 300oC) or slightly cooler (15oC) temperatures. 

Do you only have small sample amounts to work with? No problem. The GT-300 Plus has a spindle option that allows for testing with samples of just 35-50mL. (Regular spindles still only use 50-80mL!)
