Q Block Wireless Digestion System comprises of one Controller, up to eight Q Blocks and the Electronics Interface box. This system provides unparalleled value and ease of operation in performing multi-step, variable temperature profile block digestions. The Wireless Controller searches for active Q Blocks and can load recipe programs, initiate a new digestion batch and download the digestion data from the Electronic Interface. It is the same as having eight independent block digestion systems, all performing their own digestions. Each Q Block is connected to the Electronics Interface box with a power cable and temperature measuring sensor. The Electronics Interface box can maintain the commanded temperature profile and stores heating profile data independently even in absence of Controller.

Questron’s High temperature Block Digestion System is for laboratories that performs kjeldahl digestion and acid digestions of large numbers of agricultural, soil, plant and food samples under computer-controlled conditions.

Our High Temperature QBlock Wireless Digestion System has been designed for durability and robustness. It provides better quality results, higher productivity of sample throughput and uses less fume hood space per sample.

While microwave digestion systems can accelerate the digestion process, Questron’s high temperature hot blocks with dual temperature controller can digest more and larger sample sizes in one batch. We offer better flexibility in usage of a wider range of acids including sulphuric acid and perchloric acid (please note that sulphuric acid has too high a boiling point and will melt the PTFE vessels while perchloric acid can be explosive under pressure). Our Dual Temperature Controller is suitable for such High Temperature Block Digestions.

QBlock High Temperature Digestion System is also available in a Complete Wireless Model and Programmable ramping without any external computer. It is designed for EPA applications and has 5-sided high efficiency insulation. Our advanced high temperature hot block digestion system provides realtime display, archiving and data retrieval.
