  • Liquid In Glass Thermometers

    Used for accurate temperature measurement without contaminating the sample in refrigerators and incubators. Follow NIST calibration standards and come equipped with a glass bottle for storing sample

  • Wall/Desk/Window Thermometers

    Wall-mounted analogue thermometers featuring a mercury-free bi-metal sensor and blue / red scales. Can measure temperatures ranging from -30 to 60 degrees Celsius and ideal for both indoor and outdoor applications

About DURAC

The brand's extensive catalogue includes hydrometers, food service thermometers, liquid-in-glass thermometers and wall / desk / window type thermometers. H-B Durac Liquid-in-Glass thermometers feature easy-to-read scales, a lead-free shatterproof body and calibration to NIST standards. They are filled with environmentally safe liquid to minimise hazards and replace mercury thermometers with the same accuracy standards. The brand's specific gravity hydrometers measure specific gravity / relative density of lighter & heavier liquids than water with a maximum accuracy of +/-1 percent. These hydrometers are individually sterilised and can withstand temperatures up to 60 degrees F; ideal for applications in pharmacology, refrigeration and transportation applications.

Things To Consider

Cross-Reference Alternatives

Durac MPNs cross individual references to the equivalent Thermco and Vee Gee model numbers. So, if you're looking for a competitor item that is either out of stock or obsolete, chances are Raptor Supplies has the equivalent Durac products available.

Shipping

Durac thermometers and hydrometers have a small footprint and require compact packaging. Thus, these units can be delivered in a short period of time through courier shipment or air freight.

DURAC Competitive Advantages

H-B Durac Frio-Temp Blood Bank Verification Thermometers

These thermometers accurately monitor sample temperatures in blood bank refrigerators. They are filled with the Enviro-Safe liquid and supplied with an unbreakable plastic bottle filled with samples to be tested. These thermometers can be safely inserted into the liquid to get the precise temperature without contaminating the sample. These thermometers have a PFA fluoropolymer coating for ultimate protection in case of breakage and feature recyclable packaging for complete safety of critical items.

Safe-Lab Thermometer Joint Adapter

These adjustable thermometer adapters are designed for making any standard lab thermometer in an organic or inorganic process while maintaining a fully glass-enclosed system. They feature a Teflon PTFE body with a Viton O-ring for use in vacuum-related applications. These adapters come with a threaded polypropylene screw cap that must be rotated to remove or install the adapter from the flask.

Frequently Asked Questions

Why do we need to recalibrate Durac thermometers / hydrometers?

Durac thermometers & hydrometers need to be recalibrated time-to-time for accurate temperature readings in different conditions.

What is NIST?

NIST stands for National Institute of Standards and Technology. It is a non-regulatory federal agency within the U.S. Department of Commerce that promotes innovation and industrial competitiveness by advancing measurement and technology to enhance economic security and improve life.

What is the advantage of PFA fluoropolymer coating?

The PFA fluoropolymer coating offers chemical resistance, high purity and low stiffness in critical thermometers to prevent damage to glass and loss of liquid.

What are Double-Safe partial immersion thermometers?

Partial immersion thermometers provide accurate readings by immersing the thermometer in the fluid to the specified immersion depth and the remaining portion of the stem in air. These Double-Safe Series thermometers are ideal for applications in laboratories, food / beverage processes and heating technology.

What is the purpose of ungraduated thermometers?

These types of thermometers are filled with organic liquid against the white glass and are ideal for experiment purposes, determining two fixed points and the differences between Celcius and Fahrenheit scales. Students can mark their graduations for sample readings.
