What is the expiration date of your VTM?

Per CDC protocol, our VTM expires one year from date of manufacture.

Do you offer customization of your VTM?

We actively produce both VTM with and without phenol red. Phenol red is a pH indicator that is pink or red at neutral or basic pH and transitions to yellow at acidic pH, providing a visual check on medium pH. Phenol Red has been shown to turn purple in the presence of bleach, thereby allowing visual inspection to confirm that tubing was appropriately washed after bleach sterilization.

What packaging options are available for your VTM?

We can provide our VTM in various bottle sizes, the most popular sizes are our 500 mL and 1000 mL bottles.

Do you provide collection kits in addition to bulk media?

Yes, we have partnered with various companies in the US and around the world who are actively manufacturing and assembling collection kits with tubes and swabs. Please reach out to our customer service team and we may be able to help you.
