Naktuinbouw is going to stop asking for supplements materials

News publication date: 19 December 2022

From 1 January 2023, we will definitively stop asking for additions to test material. By stopping this, you as a customer will have the results sooner and we will shorten the lead times of the tests. It is therefore important that you provide sufficient material.

Monsters nemen van plantmateriaal voor toetsen

As of July 1st Naktuinbouw Laboratoria decided to stop supplement requesting sample material for testing because it is a time-consuming, disruptive and error-prone process.

Who delivers the samples?

For legal samples, Naktuinbouw takes the sample and our laboratory tests the material. The result applies to the batch/lot. In the case of services, the customer takes the sample and Naktuinbouw tests the sample. The correct quality and quantity of the sample for service is the responsibility of the customer.

How many samples were involved?

  • In 2019, there were 66 customers and 176 samples for supplement requesting.
  • In 2020, there were 62 customers and 414 samples for supplement requesting.
  • In 2021, there were 39 customers and 642 samples for supplement requesting.

In 50 percent of the cases, a supplement was provided. In the other 50 percent, this was not possible or necessary. This took a lot of extra time and work, causing a delay in turnaround times.

Since our first announcement to stop for asking supplements, we still requested supplements and also provided our clients the initial letter in which we announced the stop of requesting supplements. As of 01/01/2023 we will no longer request supplements and stop sending the initial letter! We would like to emphasize that it is important that you supply sufficient material. On our website you will find the required test numbers.
