Description
BOLA flask thermometer is a PTFE-coated glass immersion thermometer designed for temperature monitoring in laboratory reaction vessels from 2.000 to 6,000 ml (2/4/6 l). It covers a measuring range of 0 to +250 °C with a scale division of 1 °C, supporting clear, practical readings during heating and process control. The instrument has an outer diameter of 7 mm and an overall length of 600 mm, so it reaches into flasks and reactors while remaining easy to handle at the bench. The polytetrafluoroethylene (PTFE) sheath protects the glass body against aggressive media and helps maintain chemical resistance in routine organic and inorganic work. Supplied as a single piece with a net weight of 0,055 kg, this enclosed-type laboratory thermometer fits general-purpose and reaction setups where a robust, coated stem is preferred. The design from manufacturer Bohlender suits distillation, synthesis and vessel temperature checks without adding unnecessary complexity. Categories such as laboratory, rod and all-purpose thermometers reflect its everyday role in chemical and process laboratories that need a long, PTFE-protected scale thermometer for mid-range thermal monitoring.
This article is part of Laboratory glass thermometers, in Temperature measurement.

Questions about BOLA Thermometers for Flasks, 2/4/6l 0/+250:1°C L600 mm PTFE - coated
What is this article?
BOLA Thermometers for Flasks, 2/4/6l 0/+250:1°C L600 mm PTFE - coated is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Laboratory glass thermometers, inside Temperature measurement, in Lab instruments.
A liquid-in-glass thermometer is a calibrated column, often with a stated immersion depth, total or partial. The range and the division decide the reading. A partial-immersion thermometer read at the wrong depth is wrong by design.
A thermometer reports a temperature. A liquid-in-glass thermometer is a calibrated column. A digital thermometer is a sensor and a display, and the sensor, not the display, is what is calibrated. An infrared thermometer reads a surface and depends on emissivity. A data logger stores the reading over time. Without a stated uncertainty and a calibration point, the number is only an indication. The scale is maintained by the BIPM and compared by EURAMET. Accreditation is BELAC.
