Quantity

Precision liquid-in-glass thermometry without the mercury — the VEE GEE Scientific Blue Liquid Glass Thermometer delivers reliable, accurate temperature measurement across a wide range of laboratory and industrial applications using an organic, mercury-free Safety Blue fill that is biodegradable and non-toxic. Built from premium borosilicate glass with permanently etched temperature scales, these thermometers are designed for labs, universities, food and beverage processing, environmental monitoring, and wastewater treatment where accurate measurement and mercury-free certification are both required.

Each thermometer is individually serialized for calibration traceability. Available in Celsius (°C) scale across multiple temperature ranges and both Total and Partial Immersion configurations. For higher protection levels, VEE GEE also offers FEP Encapsulated, Armored, and FEP+Armored versions of these thermometers.

Features and Benefits

Mercury-Free Safety Blue Fill: Organic, biodegradable blue fill liquid performs comparably to mercury across the full temperature range — no hazardous material disposal, no mercury shipping restrictions, fully compatible with mercury-free laboratory requirements.
Premium Borosilicate Glass: High-quality borosilicate glass provides thermal expansion stability, chemical resistance, and mechanical strength for reliable performance in laboratory, food processing, and industrial measurement environments.
Permanently Etched Temperature Scale: Graduations are etched directly into the glass and filled with white enamel — the scale cannot wear, smear, or peel through repeated handling and cleaning cycles.
Individually Serialized: Unique serial number on every thermometer enables calibration record-keeping and instrument tracking for GLP, ISO, and general laboratory quality documentation.
Safety Blue Against White Background: High-contrast blue liquid column on white enamel background — clear reading in standard lab lighting conditions without magnification aids.
Total and Partial Immersion Options: Total Immersion for highest accuracy when fully submerged; Partial Immersion for applications where only the lower portion of the thermometer contacts the measured medium.
Multiple Temperature Ranges: Available in 4 temperature ranges in Celsius (°C) scale. For breakage protection, upgrade to FEP Encapsulated or Armored versions.

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 Celsius (°C) 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 Standard (no FEP or Armor) protection. What other options are available?
For breakage protection, upgrade to FEP Encapsulated (80x01E series) or Armored (80x01-A series). For maximum protection, select FEP + Armored (80x01E-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.

Quality Assurance

VEE GEE Scientific manufactures these thermometers from premium borosilicate glass with permanently etched scales and individually serialized markings. Each thermometer is filled with Safety Blue organic liquid verified for consistent performance across the full rated temperature range. VEE GEE backs these thermometers with a 1-year warranty.
