Oxygen Flask Combustion Unit

Not yet rated

Designed as a simple and safe method for igniting samples when using the Schöniger flask method. The OFCU-01 ignition cabinet protects the user should a weaken flask explode.

Your sample is ignited remotely once the flask is filled with oxygen and sealed. No need for the cumbersome task of lighting the sample manually, and then quickly inserting the sample holder into the flask and then tightening down the flask top. There is no possibility of sample loss.

The Schöniger flask method is a well proven technique for the combustion and then subsequent analysis of a range of elements including Chlorine, Bromine, Iodine, Sulfur, Phosphorus and a number of metals.

The combustion of the sample is a simple procedure and involves placing a few milliliters of absorbent solution in a flask. The sample is weighed out and placed in an ashless filter paper holder which in turn is placed in a platinum basket attached to the stopper of the flask. The flask is filled with oxygen and the stopper is then placed in the flask. The sample is combusted and the resultant combustion products are absorbed into the solution. The technique chosen for the actual determination of the element in question can be any one of a number of different techniques i.e. titration, ion chromatography, etc. The Schöniger flask combustion method is capable of being used for the determination of percentage levels to parts per million. It can cope with a wide range of sample types and is simple to set up with minimal start up costs.

The Oxygen Flask Combustion Unit is a safe and repeatable method of igniting the samples when using the Schöniger procedure. Reflectors focus the infra-red heat from two tungsten-halogen lamps onto an area approximately 10 cm above the center of the chamber. The lamps only operate when the chamber door is fully locked. The "START" switch fires the lamps for 10 seconds. In the event of a flask explosion, pressure is vented safely through holes in the chamber and any glass fragments are contained within the chamber. The unit has an aluminum interior for rigidity and corrosion resistance, and a thick black acrylic observation window.
