The Beta Gas Cell is available in two pathlengths, 5cm and 10cm. The cell consists of a Pyrex body and two Pyrex filling stems fitted with replaceable rubber septa, Viton O-rings and a cell slide holder. A leak-tight seal is made when the cell is assembled. Fill the cell using a gas-tight syringe. Two 25 x 4mm windows* are required to complete the cell. Windows are interchangeable and the procedure can be done quickly due to the demountable cell design.
