DissoPrep X8

Dissolution Media Preparation Station

The DissoPrep X8 is the innovative original Media Preparation Station with a high-precision gravimetric working principle.

The Dissolution Medium Preparation Station DissoPrep X8 (until 08/2008 DosaPrep X8) has been proven since 1998 and today is the market leader. Quality that pays off for you!

Continuous development and restriction to the essential functions ensures the highest dosing and mixing accuracy with proven reliability. Since 2012, the DissoPrep X8 has been supplemented with the DissoPrep X15 with a large 15-liter tank to simultaneously fill up to two dissolution testers. Thus, the DissoPrep series is flexible for all possible purposes and, together with the unique working principle, your guarantee for convenient and high-precision media preparation and dosing.

Innovative Working Principle

The outstanding feature of our DissoPrep is the gravimetric working principle without liquid pump(s) according to the USP method, this means that Mixing and dosing is done by vacuum and pressure with continuous weight measurement.

The suction through high vacuum (typically <100mbar) with simultaneous filtering, heating and stirring guarantees a long and efficient degassing process according to the USP method. The continuous, high-precision measurement of the weight delivers the correct standard volume for your medium required by USP at any desired temperature. Because of the known issue, that different media have different densities at different temperatures, only the measurement of the weight provides the correct standard volume. In addition there are no inaccuracies with foaming media, in contrast to the volume measurements with liquid pumps. So foaming media can be mixed with the same high precision and can be dispensed directly into the vessels. This working principle assures absolute reliability and reproducibility of medium preparation and dosage.

Extensive ease of work 

The DissoPrep X8 not only assures a reproducible and highly accurate preparation and dosage of your medium, but also rewards you with a considerable relief of your daily work routine. Compact dimensions allow the use as a desktop device or mobile on a laboratory cart to flexibly reach any dissolution tester. More than 100 different stored methods can be retrieved flexibly. Within about 12 minutes, up to 8 liters of dissolution medium are prepared and according to the guidelines of the USP, EP, JP, FDA and GLP / GMP tempered, mixed and degassed. Since this is completely self-sufficient, you can pursue other activities during this time. Thereafter you can conveniently and precisely dose it directly into the vessels and a report is automatically generated for your documentation. An automatic cleaning process cleans the complete system afterwards.

The standard browser interface for the DissoPrep integrates it quickly and easily without software installation into your IT landscape and enables you a much more easy operation with your PC. Instead of doing extensive entries on the keypad of the DissoPrep, you can use alternatively the convenient and intuitive operation on the (Internet) browser of your PC. In particular, the administration of methods, reports and users with their user permissions can be carried out quickly. You will not miss a touchscreen at the device for starting the preparation and dosing. With the optional "CFR Package" a 21 CFR part 11 compliant use of the DissoPrep is possible and the optional "Backup Package" ensures an automatic backup of your data.
