CRUDE OIL SAMPLE RECEIVERS
Welker® crude containers maintain sample integrity from the field to your lab. Whether you need stationary or mobile container solutions, Welker® has a product that will suit your application. All Welker® containers conform to API 8.2, ISO 3171, and ASTM D4177 requirements. Get the right size and the right mix with Welker®
The Welker® Constant Pressure Crude Oil Container (CPCC) is the flagship of crude containers. It mixes your product while keeping the sample under pipeline pressure to deliver an unprecedented degree of accuracy and repeatability. The CPCC is ideal for storing and mixing products that are unstable at atmospheric pressure.
A Welker® Stationary Sample Container (SCC) is perfect to meet your long term on-site mixing needs. The SCC distributes mixed product evenly throughout the container, while its top spray nozzle sprays mixed product at the rounded top of the container to force any condensate or collection of product along the lid back into the product to be mixed. Available in sizes ranging from 3-40 gallons, the SCC will mix your product at atmospheric pressure so that a homogenous sample can be collected every time.
If you need to sample at multiple sites, consider the Welker® Transportable Crude Container (TCC). TCC sizes range from 1-10 gallons, with an optional mixing skid available that allows for product mixing on-site. The optional Welker® TCC Mixing Skid (MSTCC) delivers the same features as the stationary crude container in a much smaller and portable package.
CRUDE OIL SAMPLING SYSTEMS - AUTOSAMPLERS

The Welker® LSS-1F Sampler is perfect for extracting representative liquid samples from a bypass stream under full line pressure. Its unique Vanishing ChamberTM collection head design completely voids the collection chamber of product with every actuation, making sure every “bite” of your sample is representative. Welker® LSS-1F Samplers use a double-acting air actuator that drives a positive displacement pump to move samples into a constant pressure or standard cylinder. The LSS-1F can be used on its own or as part of a larger sampling system to provide a complete solution to your liquid sampling application. Welker® will provide you with unbeatable accuracy and liquid sampling performance with our LSS-1F Sampler!
