VEE GEE Scientific FEP Encapsulated Glass Thermometer - Fahrenheit - Mercury-Free Safety Blue

When a bare glass thermometer breaks, glass fragments and chemical fill scatter across the work surface — creating an immediate safety hazard and potential sample contamination. The VEE GEE Scientific FEP Encapsulated Glass Thermometer eliminates this risk: a fluorinated ethylene propylene (FEP) sleeve surrounds the glass, and if the thermometer breaks, the FEP coating contains the glass fragments and mercury-free blue liquid fill in place, preventing injury and contamination.

The FEP layer adds chemical resistance without adding significant bulk or weight, maintaining the slim profile required for thermometer wells, water baths, and tight-clearance applications. Available in Fahrenheit (°F) scale across multiple temperature ranges in both Total and Partial Immersion configurations. Each thermometer is individually serialized for calibration traceability.

Features and Benefits

• FEP Encapsulation - Breakage Containment: Fluorinated ethylene propylene sleeve surrounds the full thermometer length — in the event of breakage, glass fragments and blue liquid fill are contained by the FEP coating, preventing contamination of samples or injury to personnel.

• Mercury-Free Safety Blue Fill: Organic, biodegradable blue liquid performs equivalently to mercury — no hazardous material disposal requirements, no mercury shipping restrictions, fully compliant with mercury-free laboratory policies.

• Individually Serialized: Unique serial number on every thermometer for calibration record-keeping, instrument tracking, and regulatory documentation in GLP and ISO-compliant environments.

• Chemical Resistance: FEP encapsulation provides an additional chemical-resistant outer layer that protects against corrosive reagent splashes and aggressive cleaning agents that could etch bare glass.

• Borosilicate Glass with Etched Scale: Premium glass construction with permanently etched temperature graduations — scale is part of the glass, not a paper or adhesive label that can be removed by cleaning.

• Safety Blue Against White Background: High-contrast blue fill against a white enamel background for clear reading in standard laboratory lighting without magnification.

• Total and Partial Immersion Options: Total Immersion thermometers for fully submerged measurement; Partial Immersion for applications where only part of the thermometer contacts the measured medium.

• Multiple Temperature Ranges: Available in 4 temperature ranges in Fahrenheit (°F) scale — choose the range that best covers your application.

Laboratory Applications

• Laboratory water bath and heating block temperature verification where liquid-in-glass accuracy and mercury-free certification are both required

• Food and beverage processing where temperature compliance monitoring requires traceable, serialized thermometers meeting mercury-free standards

• Environmental monitoring, wastewater treatment, and field sampling where general-purpose Fahrenheit (°F) measurement is required with minimal calibration overhead

• University teaching labs requiring affordable, accurate thermometers with serialized traceability for student experiment documentation

Frequently Asked Questions

What is Safety Blue fill and is it safe if the thermometer breaks?
Safety Blue is VEE GEE's organic, biodegradable blue liquid that replaces mercury in liquid-in-glass thermometers. It is non-toxic and non-hazardous — unlike mercury, a broken Safety Blue thermometer does not require mercury spill response procedures. The liquid is safe to handle and the instrument can be disposed of in standard laboratory glass waste rather than as hazardous waste.

What is the difference between Total and Partial Immersion?
Total Immersion thermometers are calibrated for use when the entire thermometer (bulb and liquid column) is submerged in the measured medium — this provides maximum accuracy. Partial Immersion thermometers are calibrated for use when only the lower portion (typically 3 inches) is immersed, with the upper portion in air. Choose Total for water baths and enclosed temperature measurement; Partial for applications where full immersion is not possible.

What does "serialized" mean for these thermometers?
Each thermometer is individually marked with a unique serial number during manufacturing. The serial number ties the instrument to production lot records and enables calibration documentation — important for GLP compliance, ISO 17025 requirements, and any laboratory quality system requiring instrument-level traceability.

This listing shows FEP Encapsulated (no Armor) protection. What other options are available?
For impact and shock protection in addition to breakage containment, upgrade to the FEP + Armored version (80x01E-A / 80x06E-A series).

How do I select the right temperature range?
Choose a range where your target temperature falls in the middle third of the scale — this provides the most accurate readings and the longest usable column length for interpolation. Avoid using thermometers at the extreme ends of their rated range, where accuracy and resolution are reduced.
