Techniguard® R-Series Tubing
Our new Techniguard R-Series rigid tubing is perfect for low flow, low cycle usage applications, such as biological freezers and other laboratory settings.
Key Features And Benefits
- Provides minimal cryogen loss, delivering significant savings, up to 58% less LN2 needed for cool down compared to traditional 1/2” piping.
- Provides a quicker cool-down than traditional vacuum-jacketed piping.
- Ideal in conjunction with a micro-bulk tank or multiple dewars in remote locations.
- Standardized bayonets for transition between vacuum jacketed tubing and Techflex cryogenic transfer hoses.
