The Dräger Halothane Vaporizer (most commonly the Vapor 19.3 or Vapor 2000 series) is a precision-engineered, agent-specific device used in anesthesia machines to vaporize liquid halothane and add it to the fresh gas flow (oxygen/air/nitrous oxide) delivered to a patient. Here is a detailed breakdown of its features, design, and function:1. Key Characteristics and Design
Agent-Specific: The Dräger vaporizer is exclusively calibrated for halothane. It features a color-coded (usually red for halothane) key-indexed filling system to prevent errors.
Variable Bypass Principle: The vaporizer splits the incoming fresh gas flow into two streams: one enters the "vaporizing chamber" (to pick up anesthetic) and the other passes through the "bypass chamber" (to skip it). These streams recombine before leaving the vaporizer.
Temperature Compensation: It features an internal temperature-sensitive element (bimetallic strip) that automatically adjusts the ratio of gas flow. When temperatures drop, less gas passes through the vaporizing chamber, maintaining a stable, consistent concentration.
High Thermal Capacity: The vaporizers are constructed with large masses of metal (e.g., aluminum) to act as a heat sink. This counteracts the cooling effect that occurs during evaporation (latent heat of vaporization).
Mounting System: Compatible with Dräger Interlock or Selectatec systems, allowing quick, secure, and safe attachment to the anesthesia machine, often featuring a locking mechanism to prevent multiple vaporizers from being turned on simultaneously.
2. Operational Details
Concentration Range: Typically calibrated to deliver halothane concentrations between 0.2% and 4–5% by volume.
Flow Range: Accurately maintains vapor concentration over a wide fresh gas flow range (typically 250 mL/min to 15 L/min).
Filling Mechanism: Designed for key-indexed fillers, which allow filling without exposing the operator to liquid anesthetic and prevent overfilling.
Transport Mode (Vapor 2000): The Vapor 2000 series allows for transport in a tilted or upside-down position without draining, provided it is turned to the "T" position.
Instructions for use D-Vapor/D-Vapor 3000 WARNING Anesthetic agent vaporizer To properly use this medical device, read and comply with these instructions for use. Typographical conventions Use of terms Dräger uses the term "accessory" not only for accessories in the sense of IEC 60601-1, but also for consumable parts, removable parts, and attached parts. These instructions for use apply to D-Vapor and D-Vapor 3000 anesthetic vaporizers.

The Dräger Vapor 2000 and Vapor 3000 series are high-precision, variable-bypass vaporizers designed specifically for the controlled vaporization of liquid sevoflurane, an essential agent for general anesthesia. They are widely used in modern operating rooms to accurately add anesthetic vapor to fresh gas flow.Key Features & Characteristics
Agent-Specific: Engineered specifically for sevoflurane to ensure accurate delivery, preventing the mix-up of volatile agents.
Temperature & Flow Compensation: These vaporizers automatically adjust to variations in temperature (operating range 10°C to 40°C) and fresh gas flow (250 mL/min to 15 L/min), maintaining consistent output.
Transport Position ("T"): The Vapor 2000/3000 series can be tilted or turned upside down during transport without leaking, enabling immediate use upon reconnection.
Large Capacity: The unit can hold the entire content of a standard 250 mL anaesthetic agent bottle (up to 300 mL), allowing for less frequent refills.
Filling System Options: Available with Key-Indexed Filling (KIF) or filling spouts, ensuring safe, agent-specific filling to prevent incorrect agent administration.
Maintenance-Free: The Vapor 3000 series requires no routine preventive maintenance or recalibration over its lifespan.
Compatibility: Compatible with Dräger Interlock 2 and Selectatec mounting systems for easy integration with anesthetic workstations.
