Use of Desiccant Tablets for MVTR Testing

What is the MVTR Testing?

MVTR is the acronym used for Moisture Vapor Transmission Rate. This is the rate used to measure the passage or permeance of water vapor through a substance. Moisture control remains a major topic when it comes to packaging in the pharmaceutical industry. The extent of damage moisture interference can cause is adverse and irreversible. 

Every substance permeates water vapor. But if how much is the question, then it can be only depicted by the MVTR value. Pharmaceutical industries have to make sure that their blister packaging is well built to protect the medicines from moisture content. To test that they will verify if the MVTR value of their packaging meets the USP standards or not.

Desiccant tablets are used to measure the MVTR of these pharmaceutical packages.

What are desiccant tablets?

These are desiccants in the form of small tablets. Desiccant tablets are used in controlling moisture content from pharmaceutical tablets and capsules. The desiccants are best suitable for blister packaging that will prevent moisture from invading inside the tablet. Being available in tiny shapes and sizes, they fit in easily in these packages even during the manufacturing process. Desiccant tablets are also used in nutraceuticals, medical diagnostics, military, and electronics.

Advantage of desiccant tablets:

  • High performance
  • Requires no additional space
  • Act as an individual adsorption device

Use of desiccant tablets for MVTR testing

Desiccant tablets being compact are extremely useful in understanding the permeance of these pharmaceutical packaging. These high-quality desiccant tablets are placed individually or as a whole over inside the blister packaging spaces. Later on, after a given period, these desiccant tablets are taken to test and verify the moisture vapor transmission rate that is allowed as per the given standard for the particular packaging. In this way, pharmaceutical packaging companies can make sure their packaging meet all the standard and keep the products safe from any kind of moisture interventions.
