Graduated flasks

Volumetric flasks provide precise results in chemistry and pharmacy. They are not scaled, but have a single ring mark that is drawn all the way round the neck to avoid reading errors.

The narrow neck results in high setting accuracy. In addition, volumetric flasks have bulbous curves in the upper area so that any gas bubbles that form can escape from the solution more easily. However, if there are gas bubbles in the solution, the volumetric flask must be swivelled slightly so that the bubbles rise to the top. In addition to volumetric pipettes and burettes, volumetric flasks are therefore the most accurate volumetric instruments in the laboratory for analysis.

 CO2 incubator, BBD 6220

Thermo

BBD 6220 provides stable growth conditions and a high degree of security and protection against contamination. Typical applications are for IVF or pathogenic work. Range: ambient + 5°C to 50°C, humidity greater than 95% R.H. and CO 2 concentrations between 0 and 20% Vol are reliably achieved via a microprocessor controlled measuring and control system. An automatic disinfection routine at 180°C, which safely eliminates bacteria, fungi and spores, decontaminates the entire interior space including the sensors and fittings. The humidity water reservoir is located outside the chamber. The water is sterilised before it is used for humidification. The stainless steel chamber is crevice-free with rounded corners for easy cleaning. Includes "Heraeus CO...
