Exhibit 99.2

Subject: Avantor’s acquisition of VWR

Dear [Customer Name]:

Earlier today, VWR announced that it has entered into a definitive agreement to be acquired by Avantor. While we are excited to share how this acquisition will support our customers across the industries we serve, we thought it was important to assure you that VWR will continue to provide the product and service solutions you have come to expect, without interruption.

By bringing together Avantor’s comprehensive offerings of ultra-high-purity materials and customer solutions with VWR’s global scale, unparalleled channel access, and deep customer relationships, we will create a vertically integrated, global player in manufacturing and supply chain solutions for the life sciences, advanced technologies and research industries.

The combined company will create a world-class global manufacturing and distribution platform with significantly enhanced scale and product breadth. Both companies share a strong commitment to quality, safety, innovation, and customer service that will be further strengthened through this combination. We will provide customers with unparalleled reliability and increased access to key products and services in both developed and emerging markets, with high-touch relationships. We will also meet evolving customer needs by providing end-to-end solutions that increase quality, effectiveness, and productivity.

Subject to receipt of regulatory approvals and other customary closing conditions, the transaction is expected to close in the third quarter of this year. During this transition period and beyond, I want to assure you that customer service and the quality of our products is, and will remain, our highest priority.

You will continue to work with our dedicated team of VWR associates and will continue to receive the high service levels that you have come to know. This acquisition does not signal a change to our value proposition – we will continue to deliver the same high-quality product and service solutions that you expect from VWR.

On behalf of the VWR team, we look forward to our continued collaboration to enable science.

Warm regards,

/s/ Manuel Brocke-Benz
