Timestrip smart indicators were used in a study by academics at Reading School of Pharmacy, part of The University of Reading, into people’s confidence in the quality of medicines.
The study focused on the potential re-use of returned medicines. It found that participants’ intention to take part in medicines re-use increased with the presence of the Timestrip® Plus temperature sensors on the packaging. The perceived social pressure to accept the medication also increased. The effect of the indicators was even greater than the promise of pharmacist visual checking of the medicines.
Although medicines re-use is not at present allowed in the UK, the presence of Timestrip indicators on packaging is understood to be a marker of their quality.

adminTimestrip Temperature Indicators Boost Confidence in Medicines – Study Finding
Timestrip®, the developer of smart indicator technology, has released two new ranges designed to be used with the latest coronavirus vaccines now becoming available. The indicators track temperature and time, and will ensure that vaccines are fresh when administered to patients.
The Timestrip Vaccine Thaw Timer is an event thaw indicator with 24 hour time indication calibrated to run at fridge temperatures. It can be packed with vaccines that require storage at -70°C in the ultra-cold chain, and automatically starts monitoring as the vaccine is thawed and transferred to chilled conditions at the hospital or surgery. It then tracks the time from thaw at 6 hours, 12 hours and up to 24 hours, meeting the specifications for use from manufacturers such as Pfizer.
The Timestrip Vaccine Refrigeration Monitor range comprises three indicators. One is designed to indicate the thawing event of the vaccine; another will time 30 days duration in refrigerator conditions (2°C-8°C), helping the user to manage the vaccine manufacturer’s guidelines for use.
Then, when the vaccine has been taken from the refrigerator and prepared for use, a third indicator monitors how long it has been exposed to temperatures above 8°C, typically at room temperature. The time ‘run out’ for the Vaccine Refrigeration Monitor VOR12 (Vaccine Out of Refrigerator) is up to 12 hours, with shorter times to an alert being seen at higher temperatures.
These Vaccine Refrigeration Monitor products will help overcome challenges in the handling of COVID-19 vaccines up to the point of administering, and are designed to support the manufacturers’ specification for the handling of vaccines such as those from Moderna.
Both indicators provide a clear irreversible indication to healthcare staff that conditions of storage and handling have exceeded acceptable conditions, and that the vaccine consignment cannot be relied upon.
Based on safe chemical technology, both the Vaccine Thaw Timer and Vaccine Refrigeration Monitor range overcome the limitations of batteries used at ultra-low temperatures.
We continue to innovate our patented technology to bring the benefits to important applications such as vaccine distribution, supply and last mile handling. Using these indicators, healthcare professionals worldwide can be supported cost effectively, and guided through soon to be routine practices of handling and managing these vital resources.

Timestrip has recently added other products to its range in response to coronavirus. These include an indicator to monitor antiviral solutions, and Rapid Diagnostics 15, a 15 minute timer indicator for use with rapid turnaround lateral flow test kits.
These indicators monitor when specimens – including coronavirus – have been stored for too long and outside the required temperature range for reliable testing.
Four products make up the VST range.
Together they form an essential tool to support hospitals, surgeries and medical laboratories in storing and transporting virus specimens correctly, and preserving their integrity.
A virus specimen’s exposure to temperature over time is critical to its lifetime, so the VST series includes a unique integrating indicator, the Timestrip VST TTI, which mirrors the accumulated time-temperature history of the virus specimen during transport and storage.
Virology specimen collection guidelines state that most viruses remain stable at 4°C for 2-3 days, so VST TTI is effective with a wide range of virus types.
Designed to meet specific regulations, the TTI label will indicate when 72 hours of chilled storage has elapsed by showing a clear visual discard window. At high temperatures, the label will show the discard indication within just a few hours.
Scientists and clinicians know that bacteria and viruses deteriorate much more quickly as temperatures increase, and also as exposure time increases. For example, at 50-55°C, coronavirus becomes non-infectious within just a few hours.
FDA and WHO regulations state that it is important to avoid freezing and thawing of specimens.
The Timestrip VST 0°Cwill reliably track a thawing event. If the ambient temperature rises above freezing, the indicator will show the cumulative period of thawing.
Timestrip VST Fridge Combi includes two indicators. One unique element indicates when a period of 72 hours has passed during chilled conditions (2-8°C), aligning with FDA / WHO regulations.
The other element provides a temperature breach indication, giving a clear signal when conditions have exceeded the regulated upper chilled limit of 8°C/46°F during storage or transport.
“As part of the fight against coronavirus, our new VST virus specimen transport range will help support scientists by monitoring specimens from collection right through to point of test, giving confidence in the integrity of the specimen, and thus the test results.
These simple yet effective products provide a solution to a real problem in the storage and handling of virus specimens, including Covid-19. Medics and laboratory technicians can now have an explicit signal when specimens have breached the safe zone of thermal exposure and are invalid for testing.”

The VST is expected to be the first of many speciality ranges to be offered by Timestrip that provide practical solutions for pathology, microbiology, mycobacteria and other laboratory specimen handling, where temperature and time monitoring are required.
From hospital curtains to pharmaceutical carts to floors, sanitation protocols need strict adherence to prevent contamination more than ever.
In response to this risk, sanitisers and sterilization products such as wipes and solutions are increasingly being put to use. As far as current medical knowledge knows, the virus is very sensitive to the cleaning and disinfecting agents currently in use.
The US Environmental Protection Agency (EPA) has determined that ‘enveloped’ viruses such as COVID-19 are the easiest type to inactivate using disinfectants.1
A spokesperson for the American Hospital Association says that while frequent cleaning is standard, hospitals are giving special attention to “high-touch surfaces such as in-room phones, TV/nurse calls, light switches and cords, handles, drawer pulls, bed rails, tray tables and bathroom fixtures.”2
However, sterilizing solutions will only achieve maximum efficacy while still fresh. They must be used within a specified period after being opened and have a limited shelf life.
Timestrip time indicators can be a valuable part of the infection control processes here, and a range of standard products is available.
