Dear valued customers,

With the extensive use of QuEChERS methodology, we are pleased to upgrade the Copure® QuEChERS products in a new generation after listening carefully to the requests of the vast number of users. This upgrade of cleanup tubes mainly improves the adaptability of the centrifuges.

Here are the pictures of the new 2-mL cleanup tube and the old 2-mL cleanup tube for reference.

We have improved appearance and geometry of the cleanup tube to meet its adaptability with different brands of centrifuges. The new cleanup tube is compatible with all centrifuges on the market.

In addition, we added an O-ring inside the screwed cap. It improves the sealing performance and prevent volatilization of organic solvents, thus further protects the health of operators and improves the repeatability of the results.


  1. The replacement of 2-mL centrifuge tube will last about 1-2 months, during this time, the new and old tube will be shipped randomly.
  2. If you have any questions during the usage, welcome to contact us.

Thank you for your support to Biocomma and our Copure® brand. We will continuously provide higher quality products and services to our customers.

Best regards.

Biocomma Limited
