2015 marks 100 years since the invention of Pyrex glass – used in almost all laboratory glassware for it’s excellent chemical and thermal resistance.
Despite it’s ubiquitous use in lab glassware, did you know the hardy material was originally developed for railroad lanterns?

“Pure” water is used in all types of laboratories for a range of uses – from making up calibration standards to cleaning and even in the rinse cycle in some laboratory glasswashers for a pure clean. There are different types of purified water available – but what is the difference?

School Science Project in conjunction with the Natural History Museum (NHM) and Vivacity Culture and Leisure Peterborough, Flag Fen.
The Museums and Schools project is funded by DfE through an Arts Council England programme that has partnered 10 regional museums with national museums with the aim to develop high quality visits and learning opportunities for schools, particularly those in less affluent areas, or areas of low engagement.
Peterborough Vivacity and NHM (via the Real World Science team) have worked in partnership to explore and develop new opportunities for upper primary and secondary students to access science learning through natural history collections and exploring the unique archaeology, environment and scientific research represented by Flag Fen.

General function and description:
The sample (serum, blood, urine or any other aqueous solution) is filled in a plastic sample tube and cooled via a Peltier element. These are semiconductor devices, which become cold on one side and warm on the other when electrical current flows through. The cold side cools the sample whilst the heat from the warm side dissipates into the air by convection.
The Löser-Osmometer and Cryometers transports the warmth via cooling surfaces into the atmosphere, an extra water supply is not necessary. Operation of the instrument requires only an electrical socket. The temperature on the cold side is kept electronically constant. During the measuring process the temperature of the sample is measured by a thermistor (a temperature dependent resistor). This is the part of the measuring head onto which the tube is placed. The measuring head is attached to guide rods which protect it from accidental damage. At a defined super cooling the freezing process is started by lowering a needle with ice crystals into the sample tube. The freezing point of the sample will be reached. The method of initiating the freezing process is important for the reproducibility of measurements. Dipping a needle with ice crystals into the sample gives more exact results than stirring with a wire which is constantly dipping into the sample. Because of linear correlation between osmolality and freezing point the measurement of freezing point is
a determination of osmolality. The results are displayed in mosm / kg H2O.
