Logtag Buffer Bottle

LogTag® Buffer Bottle for Accurate Temperature Monitoring
Compatible with LogTag® standard and low-temperature data loggers

• Leak-proof screw cap

• Refillable with glycol or sand

• Realistic temperature representation for vaccines and sensitive products

• CDC-compliant for vaccine monitoring

Description

The LogTag® buffer bottle provides a reliable simulation of the temperature inside a vaccine vial or sample container. By buffering rapid temperature changes—such as those caused by opening a refrigerator—it minimizes short-term temperature spikes and delivers a much more accurate indication of the actual product temperature during storage or transport.

The sensor is securely fixed inside the bottle, ensuring stable and consistent measurements. The bottle is leak-proof, reusable, and suitable for use with glycol or silica sand (for measurements down to -90 °C).

Applications

Suitable for pharmaceutical refrigerators, laboratories, vaccine storage, and refrigerated transport.
