What kind of swabs are included in the VTM Collection Kit?

What kinds of COVID-19 sample collection kits are available?
Captivate Bio bulk manufactures viral transport media that can be used for in-house assembly of COVID-19 collection and transport kits. We are also an authorized distributor of Ruhof’s Viral Transport Medium & Flocked Swab Kits.
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 and VTM Collection Kits?
We can provide our VTM in various bottle sizes, the most popular sizes are our 500 mL and 1000 mL bottles. Bulk VTM Collection Kits are also available. For quantities of 1000 or more, please contact our customer support team for more information and to request a quote.
