Hvor skal prøven tas?

The sample should be taken from a representative point in the system – preferably from the return line, tapping tank or sampling point. The most important thing is that the sample reflects the actual condition of the oil in operation. Avoid taking samples from bottom sludge or from components that are not in circulation.

Jeg har prøveflasker fra noen andre, kan jeg sende disse til dere?

Yes, you can send samples in your own bottles as long as they are clean, tightly closed and clearly labeled. Please remember that our analyses require a minimum quantity and that we need sufficient information about the sample to perform the correct analysis. Please contact us if you are unsure.

Hvordan skal prøven tas?

The sample should be taken in a clean bottle, while the oil is warm and circulating, preferably just after the system has been in operation. Avoid contamination by using clean hose and gloves. Fill the bottle approx. 80%, and clearly label it with the sample date, component and, if applicable, customer number.

Hvorfor må jeg bruke ny slange?

A new hose ensures that the sample is not contaminated by residues from previous samples. Reusing a hose can lead to inaccurate analysis results, and in the worst case, incorrect interpretations of the oil condition. Therefore, we always recommend using a new hose for each sample.

Kan dere ta prøver for meg?

Yes, we can offer sampling on request in selected areas or for special needs. This can be arranged directly with our team. Contact us to find out if we can assist with sampling where you are located.

Oil sample guidance

Sampling

Here is an instruction manual that allows us to provide you with a condition report that is as representative as possible of the actual conditions in your machinery and equipment.

Why take oil samples?

Regular oil testing is a simple and affordable investment in the condition monitoring of your machinery and equipment. Oil analysis can detect abnormalities at an early stage and allow you to take action before major damage occurs. In addition, savings can be achieved through extended oil change intervals.

How do you take a good oil sample?

Vacuum pump usage instruction

For optimal results, take the oil sample immediately after shutdown. Cut a piece of plastic tubing, slightly longer than the dipstick. Thread one end through the vacuum pump and tighten the pump. Approximately 4 cm of the tubing should point down into the sample bottle. Attach a bottle to the pump.

Insert the tube into the desired location and keep the plastic tube below the oil level throughout the process. Hold the pump vertically and pump the bottle 3/4 full.

Pull up the hose, remove the bottle from the pump and screw the cap back on tightly. Label the sample. Use our pre-printed labels if you have them. Otherwise, label the sample with the company name, component name, oil type, operating time of the oil and component, date of sampling and whether an oil change was performed in connection with sampling.

Use a new hose for each sample. If oil gets into the pump, it must be dismantled and washed before it can be used again. If the system is equipped with a drain valve, this can be used for sampling.

Remember this:

Take oil samples in disposable bottles. We need 50 ml for analysis of lubricating oil, 100 ml for hydraulic oil, cooling water and diesel.
When submitting a component for the first time, we recommend that it be sent with a reference oil/clean sample of the same oil type used on the component.
Please include an email address to which the condition report should be sent.

We are available to provide sample bottles, sample tubing, pre-printed labels and pre-stamped envelopes to our customers. Please contact us for more information.

See our guidance leaflet for how to conduct sampling.
