RU-20: Manage your reagents efficiently 

Lab staff often spend much of their time handling and replacing reagents. And in haematology, the volume of some reagents used, such as the diluent, is high compared to other laboratory work areas. 

Sysmex’s reagent unit RU-20 is a comprehensive and intuitive supply system that creates an extended ‘walk-away time’ so that your lab staff’s time can be better spent on other tasks. 

The RU-20 is simply connected to your lab’s existing water purification system and then to the analysers. You now have safe, pure reagents on tap, automatically prepared from a reagent concentrate. 

The number of boxes you need to connect is cut significantly. You will have less packaging waste and far less goods handling in general. You can also simplify your logistics and purchasing processes, as well as your administration. 

The RU-20 has been developed as an optional part of XR-Series and XN-Series automation lines to provide ready-to-use diluent out of the Cellpack DST concentrate. It improves the XR and XN lines’ performance by optimising the overall work process. 

For every lab with > 150 blood counts / day 

Reagent delivery is an issue for haematology departments in their day-to-day operation – for example because this generally requires a lifting cart. Storage is limited and usually not located near the haematology work area. And you need to spend a lot of time and attention at your analyser, ensuring reagents are delivered properly. 

If your lab handles >150 EDTA blood samples each day, the RU-20 will help. The number of reagent changes can be decreased significantly, providing greater instrument availability and an improved workflow. You do not have to interrupt routine operation, not even when the reagent is being replaced. 

We provide two reagent package sizes (10 L and 20 L) of the Cellpack DST concentrate, suited to different daily sample processing volumes. The open stability is 60 days. 

Using the RU-20 with the Cellpack DST will not only relieve your staff from frequent lifting of heavy boxes, but also make most efficient use of limited storage space in the laboratory warehouse: By using Cellpack DST instead of Cellpack DCL, the storage room needed for 25 boxes can be reduced to the room needed for just one box. 

Easy and safe reagent supply 

You can connect the RU-20 generally to your lab’s existing water purification system. Integrated filter systems make sure that the ready-to-use Cellpack is free of germs and particles and available for analysis at any time. This way, the RU-20 ensures that individual samples can be processed at night or during an emergency, without the quality of the reagent being affected. 

To make sure that reagent management is efficient and meets present requirements, the RU-20 reagent unit can be controlled via the haematology analysers connected to it. An alert management is provided via the RU-20’s display and an alarm sound. 

Using the RU-20 system means you have a reagent supply on site, which guarantees reagent availability 24/7.
