10 self-sealing injection ports
The perfect inoculation-hole for almost every type of substrate container. Just make a hole of 6mm in your substrate container and press these ports into it. This will hermetically seal your container. These ports survive the pressure cooker without any damage and can be injected up to 10 times and still seal off your sterile substrate.
One of the great advantages of these ports is that they make it possible
to inject the spores at any non-sterile place, without having a high
risk of contamination. Just clean these ports with some rubbing alcohol
before injecting. Do not enter the injection port with a hot needle this
might damage the injection port.
