Low form Beakers and High form Beakers

The difference between Duran centrifuge tubes and other types of tubes is their wall thickness and their sturdy design. They have to withstand the high loads generated in laboratory centrifuges. The mixture to be separated rotates at high speed around an axis in the centrifuge tube. This causes the heavier particles to fly faster and further away from the axis than the lighter ones. This results in separation.

These tubes are approved to DIN 58 970 (Part 2) for a maximum relative centrifugal acceleration of 4000 and filling in line with their capacity with contents having a maximum density of 1.2 g/ml.

Schott Duran cylindrical and conical culture bottles are mainly used for developing cultures to grow media. These are closed with cotton wool plugs, metal caps, glass caps, etc. It is important that an exchange of air to take place while maintaining sterility. The neck finish of the bottles is generally straight (i.e. not a beaded rim). The beaded rim is, of course better for pouring purposes (no drips), but it increases the risk of contamination, since microorganisms can become trapped under the rim.

• Penicillin flasks

The difference is the shape.

Typical uses for Schott Erlenmeyer flasks include boiling and swirling. They are also used as components in apparatus. Their shape makes them ideal for mixing and storing liquids.

An advantage of the conical shape is that there is little tendency for precipitates to stick to the inside surface as they slide down the wall with the rest of the contents. Duran Erlenmeyer flasks are also used as culture flasks.

Schott Duran glass filter crucibles have a wide range of applications in quantitative analysis. They are particularly suitable for precipitates which need to be dried to a constant weight. After careful cleaning, the filter crucible quickly reaches a constant weight at 110°C, as the water remaining evaporates. After filtration the moist precipitate is placed in the Duran glass filter crucible in the hot drying cabinet at a temperature up to 150°C where it is dried to a constant weight.

Depending on the method of determination, it can be cooled by exposure to air or in a desiccator. To calcine a precipitate, the crucible is placed in a cold oven, which then can be heated up to a maximum of 500°C. After the oven has been switched off, the crucible should be allowed to cool down to about 200°C in the oven.

Filtering flasks are used for drawing off liquids and vacuum filtration. Duran filtering flasks are available in both conical and cylindrical form. To ensure suitability for use under vacuum they have an appropriate wall thickness. DIN 12 476 prescribes an appropriate pressure test to ensure that items are suitable for use under vacuum. All Schott filtering flasks are suitable for use under vacuum.

Duran filtering flasks with plastic hose connections and plastic tubulatures provide protection and safety for laboratory workers and the laboratory. Their design makes it easier to fit and remove the vacuum tubing.
