PreeKem TOPEX+

INTRODUCTION

The TOPEX+ Microwave Digestion System is a robust, safe and easy to use high throughput microwave digester manufactured by PreeKem. Designed in Germany with advanced microwave technology and intuitive software the TOPEX+ can completely digest the most demanding samples at the same time and under the same conditions. It can also be configured for extraction and synthesis to offer users a convenient sample preparation solution.
