Automated monitoring of temperature and humidity in the storage of pharmaceuticals in pharmacies and hospitals with testo Saveris 2

In pharmacies and hospitals, the health of the patients is of primary importance. Here in particular, it is all the more important to consistently avoid risks that arise due to the improper storage of drugs or units of blood. Temperature- and humidity-sensitive drugs must be stored under controlled climatic conditions and their compliance continuously monitored and documented. Those in charge need to spend a great deal of time on this, because errors can have costly consequences: just one pharmacy refrigerator often stores drugs with a value of 20,000 euros – not to mention the value of a good reputation.

With the testo Saveris 2 cloud-based measurement data monitoring system, Testo has taken a new approach to monitoring temperature and humidity and significantly simplified the automated collection, storage and analysis of measurement data. The WiFi data loggers installed at all relevant refrigeration points can be read out via WLAN, so the data is accessible anywhere and at any time via the Saveris Cloud. Alerts are sent out automatically if limit values are violated. You can therefore monitor all the relevant ambient conditions in the refrigerators, dispensary, laboratory and prescription preparation areas – really easily, at any  time and  anywhere.

The challenge

Almost all pharmaceutical products are sensitive to temperature and humidity, lots even have to be stored  in  a cold chain, so they typically need to be stored at temperatures between 2 °C and 8 °C. At the same time, when it comes to lots of modern drugs, greater temperature and humidity fluctuations are problematic and therefore need to be avoided. For example, freezing only once can considerably impair the efficacy of drugs containing proteins – these are then no longer usable and represent a corresponding loss for the pharmacist. Since it has been proven that even less sensitive products cannot tolerate large fluctuations, the “Controlled Room Temperature” (CRT) of +25 °C for storing drugs has also played an increasingly important role.

In hospitals, units of blood and laboratory samples, as well as drugs, need to be monitored continuously, and add to   that monitoring the climate of waiting and recovery rooms, operating theatres, intensive care units, cleanrooms and kitchen areas. Anywhere, and at  any  time, compliance with the  permissible temperature  and  humidity values in  each case must be guaranteed and documented – a considerable extra  effort for  the  already greatly stretched hospital staff.

The solution

Progressive digitization and automation opens up completely new possibilities for monitoring climate in the pharmaceutical sector. The testo Saveris 2 cloud-based measurement data monitoring system automates the entire measurement procedure: with the testo Saveris 2 WiFi data loggers, temperature and humidity values in sales and storage areas and also in refrigerators are recorded in a fully automated process and transmitted to the Testo Cloud via WLAN, where they are safely and permanently stored. From there, they can be retrieved from anywhere and at any time  via a standard web browser – on an office PC or a  smartphone while out and about. Special software, as is the case with conventional monitoring systems, is not required here – there’s no need to install or constantly update anything. Thanks to the many different visualization options offered by testo Saveris 2, even the previously time- consuming documentation of results is really easy. This saves valuable time and money, and at the same time ensures that all legal regulations and standards are complied with. Even if limit values are violated, safety is always guaranteed: Saveris 2 alerts those in charge via SMS, e-mail or app (push alert), so they can respond immediately in case of emergency.

The advantages at a glance

  • Automated, reliable  temperature monitoring
  • Measurement data accessible from anywhere and at any time, even using a  smartphone or  tablet while on  the move
  • Save time and money with automated read-out of data loggers
  • Scalable with other data loggers as  required
  • Automatic alerts in the event of limit value violations or malfunctions
  • Very high security, because the data is stored in duplicate

– in the cloud and in the data logger

Vion IMS QTof: Beyond Resolution – Seamlessly from Samples to Answers

Complex samples give complex data with overlapping spectra and background interferences, making compound identification difficult and method development costly and time consuming,. Sometimes, resolution and accurate mass are not enough to identify analytes, so additional experiments are needed, making even routine analysis slow and inefficient.

VionTM IMS QTof moves ion mobility mass spectrometry from research to routine. Rely on ion mobility to clean up and simplify every spectrum, so interpreting your data is easier than ever. Find, identify and quantify your analytes confidently, enabling faster method development and higher sample throughput.

Waters’ innovation and commitment to ion mobility brings you our most exciting benchtop platform: Vion IMS QTof, a high resolution benchtop QTof mass spectrometer that delivers the selectivity of ion mobility to ever scientist for every analysis.

Information on Vion IMS QTof will be available at Lab Indonesia 2016, pre-register to the exhibition and visit Waters’ booth @ Q01.
