The AL450 is a modern, microprocessor-controlled photometer with ergonomic keyboard and large graphic display. It has a variety of pre-programmed methods based on the proven range of AQUALYTIC® reagent tablets, liquid reagents, cell tests and powder reagents (VARIO Powder Packs). Storage of own methods is additionally possible. The AL450 is a filter photometer with 6 interference filters of different wavelengths. The uniquely designed optics allow the automatic selection of the required wavelength without any moving parts. This and the two-beam technology with an internal reference channel guarantees highest accuracy. The 7 standard rechargeable battery cells included in the delivery allow easy mobile use. These standard cells are available worldwide and are easy to change. The intelligent charging control integrated in the unit allows the batteries to be charged and the unit to be operated at the same time using the power supply unit supplied. Alternatively, operation without a power supply unit is possible with alkaline manganese batteries. The entire unit, the measuring shaft, the most critical assembly of any photometer, and the battery compartment are completely sealed to prevent water from reaching the electronic components. Verification standard kit free of charge As part of our promotion, the verification standard kit is available free of charge. The verification standards for the AL450 are used to check the detection accuracy and reproducibility of measurement results, related to the integrated wavelengths. The shelf life of the standards is two years from the date of manufacture if used and stored properly. Measurements are made in units of mAbs. Scope of delivery The instrument is supplied complete and ready for use, including 7 batteries and charger, 100-240 V, PC connection cable, 3 cuvettes 24 mm, 3 cuvettes 16 mm, 1 adapter for 16 mm cuvettes, 3 syringes, 1 plastic beaker 100 ml, case with waterproof insert, but without reagents. Please specify the reagent sets or parameters you require when ordering. Traceable to N.I.S.T The instrument is factory calibrated to international standards which are not traceable to N.I.S.T.. The user can adjust the unit to standards traceable to N.I.S.T. in “User Adjustment Mode”. (N.I.S.T. = National Institute of Standards and Technology) Polynomials The user creates the corresponding polynomial from the measured data pairs (concentration/absorption) with the help of an external, mathematical programme. An already known polynomial can also be used. Up to 25 fifth-order polynomials (y=A+Bx+Cx2+Dx3+Ex4+Fx5) can be stored with user-specific parameters such as wavelength, measuring range and unit. Concentration With this function, 2 to 14 standards can be measured. The photometer saves the obtained value pairs as a method (up to 10 methods). If samples are measured with this method, the photometer determines the sought concentration value by linear interpolation between 2 value pairs.
