SAMPLING RESOURCES

Better context begins
before the sample.

A representative sample and a complete record make laboratory results more useful. Use this guide to prepare your program.

Before you ship: contact us to confirm sample acceptance, the receiving location, container type, required volume, methods, price, and timing. The listed Houston address is a business contact address; do not assume it is a sample receiving dock.

01 / AGREE ON THE SCOPE

Start with a question.

Is this a routine check, an unexpected lab result, suspected contamination, or a change in equipment behavior? Explain what prompted the inquiry and what decision the results need to inform.

Identify the equipment and the exact lubricant product.
Share existing laboratory reports and relevant product information after arranging a transfer method.
Confirm the analytical scope and sampling requirements before collecting material.

02 / COLLECT CONSISTENTLY

Follow the agreed sampling procedure.

Use your site’s approved procedure and the instructions agreed for the equipment and test method. Sampling points, operating conditions, containers, and required volumes vary.

Use the specified clean, compatible sample container.
Keep tools and containers protected from contamination.
Use a consistent, designated sample point for trend monitoring.
Record whether the sample was collected during operation or after shutdown.
For grease, agree on the collection location and procedure first.

Only trained personnel should sample machinery. Follow site procedures for hot fluids, pressure, moving equipment, and isolation.

04 / ARRANGE SHIPMENT

Confirm acceptance before dispatch.

Obtain receiving instructions and identify any special handling requirements. Use compatible packaging and a secure closure, and provide the product safety data sheet when requested.

Shipping classification and carrier requirements depend on the actual material. Do not send unknown or hazardous materials without prior arrangements.

COMMON QUESTIONS

Before you
send a sample.

How much material do you need?

Volume depends on the agreed methods and any repeat or additional testing. Confirm the required volume and container with us before sampling; grease and oil requirements differ.

Can you review a report I already have?

Yes, start with an existing report interpretation inquiry. Tell us the report format, lubricant, equipment, and question. We will agree on the scope and how to transfer the report before you send files.

Do you only work with Castrol products?

No. We welcome inquiries for lubricants from different manufacturers. Our Castrol Tribol focus is an independent, product-specific area of interest and does not imply manufacturer affiliation.

What will testing cost, and how long will it take?

Pricing and timing depend on the program, methods, sample requirements, and analysis arrangements. These details are confirmed before work is accepted. No standard turnaround is promised on this website.

Can I bring a sample to the Houston address?

Please call first. The address is our business contact address. Sample receiving instructions, including the correct receiving location, must be confirmed before any shipment or delivery.
