During wellhead or separator sampling the oil or gas cylinders require proper and secure positioning, to avoid sand or dirt ingress into the valves. In the PVT laboratory it is important to use the correct cylinder stand for individual oil and gas bottles to ensure stable connections to the PVT circuit. Leutert supplies suitably welded bottle stands that allow for safe and professional operation in the field and in the lab. The valves of the sample cylinders are fully accessible.
