The GE Datex Ohmeda TEC 7 Sevoflurane Anesthesia Vaporiser is an agent-specific anesthesia vaporiser engineered to deliver precise and reliable sevoflurane concentrations across a wide clinical flow range.Â
Designed for use with supported anesthesia machines, the TEC 7 vaporiser combines accurate anesthetic delivery, ergonomic controls, and advanced safety features to support operating rooms, surgical centres, and healthcare facilities.
The Datex Ohmeda TEC 7 Vaporiser is designed to provide consistent anesthetic output throughout a clinical flow range of 200 mL/min to 15 L/min. Its precision-calibrated control dial and advanced wick system help maintain stable sevoflurane concentrations, supporting safe and efficient anesthesia administration during surgical procedures.
Available with Easy-Fil and Funnel Fill configurations, the TEC 7 vaporiser is engineered to minimise anesthetic leakage during filling while simplifying routine maintenance and operation.

Sevoflurane Calibration and Performance
The TEC 7 Sevoflurane Vaporiser is calibrated specifically for sevoflurane delivery up to 8% volume concentration. The concentration dial features precise graduations to help clinicians accurately adjust anesthetic output during procedures.
Calibration Details
- 0% to 1%: 0.2% increments.
- 1% to 8%: 1% increments.
- Factory calibrated using oxygen at 5 L/min and 21°C.
Accuracy
At 5 L/min oxygen flow and 21°C ±2°C:
- Accuracy tolerance: ±0.4% of delivered anesthetic concentration.
- Alternatively, ±15% of the selected dial setting, whichever is greater.
