Go Direct Mini GC can connect via Bluetooth® wireless technology or wired via USB to your device, providing an opportunity for you to choose the solution best for your laboratory.
Developed with Seacoast Science, Go Direct Mini GC uses an efficient, software-controlled internal pump system. This design allows the Go Direct Mini GC to use room air as the carrier gas, so there is no need to purchase an external carrier gas tank or maintain a gas filtration system.
You can also use this gas chromatograph to identify unknown compounds, monitor chemical reactions, and measure products from a distillation.
