Enzymatic assays: From single to high-throughput testing

Discover the versatility of enzymatic test kits in analysing wines, fruit juices, and dairy products. At R-Biopharm AG, we understand the diverse needs of our customers, ranging from small- to large-scale industrial labs. Our offerings include:
For single testing
Effortless testing with RIDA®CUBE Kits: Ideal for settings without a lab, these kits require just one pipetting step. Utilize the RIDA®CUBE SCAN for results in 15 minutes. Experience simplicity with pre-filled cartridges and the assurance of precise, quantitative outcomes.
For low to medium throughput
The distinctive features of the Enzytec™ Liquid kits are ready-to-use, stable reagents and a standardized testing procedure, involving only three pipetting steps. Furthermore, Enzytec™ Liquid contains two independent sets of reagents to lower risk of contamination.
For medium to high sample throughput
Flexibility with Enzytec™ Liquid kits: Optimized for both manual and automated use, these kits are compatible with any analyzer, such as the Pictus 500, leading to high-volume testing efficiently.
Unique highlights of our modern Enzytec™ Liquid product line:
Enzytec™ Liquid Ethanol: Recognized as the AOAC-Official Method of Analysis (2017.07) and recommended by theo Codex Alimentarius Method (Type IV).
The following products in the Enzytec™ Liquid line are also recognized as AOAC-Official Method of Analysis (OMA):

Enzytec™ Liquid Citric Acid: The only citric acid test kit world-wide with stable, liquid reagents.
Our Enzytec™ Liquid Multi-acid standards and Enzytec™ Liquid Multi-sugar standards contain 7 acids or sugars at different concentrations: low and high. These external multi-acid and multi-sugar standards ensure accuracy and cost-effectiveness of enzymatic testing.
