The Wincom Glass Thermometer is a classic, high-precision laboratory instrument engineered to deliver exceptionally accurate temperature readings in scientific, educational, and industrial environments. Built with a heavy-walled, chemically hardened borosilicate glass tube, it features a highly sensitive liquid expansion capillary column that responds instantly to thermal shifts. This non-reactive, solid-stem thermometer is a fundamental tool specified for monitoring chemical reactions, distillation setups, fluid heating, and general quality control testing.

Technical Specifications

• Instrument Type: Solid-Stem Liquid-in-Glass Laboratory Thermometer

• Liquid Filling Formats:

  • Red/Blue Organic Spirit (Eco-friendly, high-visibility alcohol filling)

  • Laboratory Grade Mercury (For ultra-precise, high-range calibration)

• Measurement Scale: Permanent dual or single scales in Celsius (°C) and Fahrenheit (°F)

• Standard Measurement Ranges: Available in multiple institutional lengths and ranges:

  • -10°C to 110°C (Standard chemistry laboratory variant)

  • -10°C to 250°C / 360°C (Extended high-temperature configuration)

• Scale Graduation/Resolution: Precision etched lines at 1°C or 0.5°C intervals

• Total Structural Length: Industry-standard immersion depth (typically 300mm length)

• Outer Tube Material: Highly transparent, thermal shock resistant borosilicate glass

• Mounting Integration: Molded glass top loop or anti-roll plastic cap with suspension hole

Key Features

• Fused High-Contrast Markings: Features deep, permanently etched scale graduations with fused-in pigment that stays 100% readable, resisting wear even after repeated scrubbing or exposure to hot chemical vapors.

• Premium Contrast Background: Designed with a built-in white or yellow enamel backing strip behind the capillary tube, making the rising liquid column highly visible from a distance.

• Anti-Roll Safety Cap: Outfitted with a specialized hexagonal plastic cap at the top end, preventing the round glass tube from rolling off flat laboratory benches and shattering.

• Ultra-Responsive Thermal Bulb: Engineered with a precision-molded, thin-walled bottom bulb that ensures maximum thermal conductivity, allowing the internal fluid to stabilize rapidly within seconds of immersion.

• Absolute Chemical Inertness: The robust borosilicate glass structure does not react with concentrated acids, aggressive alkalis, or organic solvents, making it completely safe for chemical synthesis workflows.

Primary Applications

• Chemistry Labs and Solution Heating: Tracking boiling points, melting points, and ambient fluid temperatures during exothermic or endothermic chemical reactions over Bunsen burners.

• Distillation and Reflux Assembly: Positioning securely inside distillation adapters and fractionating column heads to monitor exact vapor phase temperatures.

• Biological and Media Incubation: Verifying temperature uniformity inside heating mantles, laboratory water baths, agar autoclaves, and biological sample ovens.

• Food, Beverage, and Dairy Testing: Monitoring pasteurization consistency and checking thermal baselines inside commercial liquid tanks or quality inspection lines.
