DURAC PLUS

DURAC PLUS is a brand of analog bottle thermometers designed for precise temperature monitoring in laboratory, medical, and industrial environments. The product line focuses on glass-bead-filled bottle thermometers that provide stable, drift-resistant readings across a wide range of applications, from ultra-low freezers to high-temperature ovens. Each thermometer consists of a liquid-in-glass stem encased in a sealed bottle filled with glass beads, which act as a thermal buffer to simulate the temperature of stored materials. This design is particularly suited for environments where temperature uniformity and response time are critical, such as incubators, water baths, blood banks, vaccine storage, and laboratory ovens. The thermometers are available in multiple temperature ranges, including -90°C to 25°C, -30°C to 1°C, -2°C to 10°C, 10°C to 45°C, 15°C to 30°C, 15°C to 50°C, and 50°C to 200°C, with accuracies ranging from ±0.4°C to ±2.5°C depending on the range. Bottle volumes are either 30 mL or 60 mL, and all units are calibrated in degrees Celsius. The glass bead fill medium eliminates the risk of liquid spillage and provides a stable thermal mass, making these thermometers suitable for regulatory compliance in clinical and pharmaceutical settings. 3G Electric supplies DURAC PLUS bottle thermometers as part of its catalog of industrial and laboratory instrumentation, supporting global procurement for plant engineers, maintenance managers, and procurement specialists who require verifiable temperature monitoring solutions. The thermometers are typically used as secondary reference devices for routine checks or as continuous monitors in controlled environments. No electronic components or batteries are involved, ensuring long-term reliability without calibration drift from electronic sensors. The analog design allows for direct visual reading without the need for external power or data logging equipment, though users may integrate them into manual logging protocols. 3G Electric offers logistics support for international orders, ensuring that these glass instruments are packed and shipped to minimize breakage risk. The product range covers the most common temperature bands required for cold chain management, incubation, and thermal processing, making DURAC PLUS a practical choice for facilities that need simple, repeatable temperature verification without the complexity of digital systems.

Pertanyaan yang Sering Diajukan

Pertanyaan umum tentang DURAC PLUS dari 3G Electric.

What is the typical accuracy of DURAC PLUS bottle thermometers for vaccine storage applications?

For vaccine storage environments, DURAC PLUS offers models with an accuracy of ±0.4°C in the range of -2°C to 10°C (SKU 12L969) and ±0.4°C in the range of 15°C to 30°C (SKU 12L970). These accuracies meet common requirements for monitoring refrigerated vaccines and blood bank storage, where temperature deviations must be kept within narrow limits. The glass bead fill provides thermal buffering to simulate the temperature of stored vials.

How does the glass bead fill medium in DURAC PLUS thermometers affect response time compared to liquid-filled bottles?

The glass bead fill in DURAC PLUS thermometers provides a slower thermal response compared to liquid-filled bottles, which is intentional. The beads act as a thermal mass that mimics the temperature behavior of solid or semi-solid stored materials, such as vaccine vials or biological samples. This design reduces the influence of transient air temperature fluctuations, giving a more representative reading of the actual contents. Response time is typically several minutes, suitable for steady-state monitoring rather than rapid temperature changes.

Can DURAC PLUS bottle thermometers be used in ultra-low freezers operating at -80°C?

Yes, DURAC PLUS offers a model (SKU 12L976) with a range of -90°C to 25°C, which covers ultra-low freezer temperatures down to -80°C. The accuracy is ±1.5°C from -50°C to 25°C and ±2.5°C below -50°C. The glass bead fill remains stable at cryogenic temperatures, and the sealed bottle prevents moisture ingress. Ensure the thermometer is placed in a representative location within the freezer, such as in a sample container or rack, to obtain meaningful readings.

What is the bottle volume of DURAC PLUS thermometers, and does it affect placement?

DURAC PLUS bottle thermometers are available in 30 mL and 60 mL bottle volumes. The 60 mL models (SKU 12L969 and 12L970) are typically used for blood bank and vaccine storage applications where a larger thermal mass provides more stable readings. The 30 mL models are common for incubators, freezers, and ovens. The bottle size does not affect the temperature range or accuracy but may influence how the thermometer fits into sample racks or containers. Both sizes are designed to be placed in a representative medium, such as a glycol bottle or glass bead-filled vial, to simulate the stored product.

Are DURAC PLUS bottle thermometers suitable for use in laboratory ovens up to 200°C?

Yes, DURAC PLUS offers a model (SKU 12L981) with a range of 50°C to 200°C, specifically designed for lab ovens. The accuracy is ±2.5°C up to 100°C and ±5°C above 100°C. The glass bead fill and glass construction can withstand continuous exposure to these temperatures without degradation. However, the thermometer should not be subjected to rapid thermal shock, such as moving directly from a hot oven to a cold surface. Allow the unit to cool gradually to prevent glass breakage.

How should DURAC PLUS bottle thermometers be calibrated or verified in the field?

DURAC PLUS bottle thermometers are factory-calibrated and do not require user calibration. For field verification, compare the reading against a certified reference thermometer in a stable temperature bath or dry block at a known temperature point. The glass bead fill ensures that the thermometer reaches equilibrium within the verification medium. If the reading deviates beyond the stated accuracy, the thermometer should be replaced, as the sealed glass construction does not allow adjustment. Regular verification intervals depend on regulatory requirements for your application, typically annually or semi-annually.
