Verification of devices

The second-hand devices are verified by Labexchange Service GmbH before delivery. You are receiving only fully functional devices.

Dispatch time

The stated dispatch times are the shortest possible ones for each article. The effective dispatch times can vary. The effective dispatch times will be stated in the order confirmation.

As a matter of principle, we are offering collective deliveries. The shipping time is calculated based on the position with the longest lead time. A partial delivery is possible on explicit request.

Shipping methods

Parcel services, forwarding agencies, self-pickup, delivery by Labexchange fleet.

Delivery information

Prices exclude shipping costs. Stated shipping costs are to be expected. Deviations are possible. If transport costs are not specified, please ask separately for them.

The stated transport and packing charges apply to the most favorable route if transport and are to be understood as subject to verification due to unexpected cost increases. By reason of unpredictable events, cargo rates and delivery times can change at any time and therefore have to be adapted to the recent situation. Import formalities and possible customs charges will be borne by the purchaser. Incoterm coding according to Incoterms 2010: For persons who collect the devices themselves: EXW, for dipatch by sea: CFR, by air freight: CPT, other shipments: DAP. Note for international shipments: A proof of preference/EUR1 will not be issued by us. When self-collecting/ordering EXW from countries within or outside the European Union, 16% VAT will be retained as a deposit until we have received the corresponding confirmation of arrival/bill of delivery from the buyer.

Terms of payment

We do not accept payment by letter of credit, PayPal, etc. In each case the invoice amount is payable without deduction. Discount is not granted.

Filter photometer NANOCOLOR® 300 D

The NANOCOLOR® 300 D is not only a high-performance filter photometer, it also features versatile software capabilities. With its arge reserves of light at all wavelengths, the user can perform precise measurements, even at high extinctions.

Storage of all NANOCOLOR® analytical methods and multilingual user guidance facilitate measurement. Additional programmes such as measurement of extinction, kinetics, data networks, etc. expand the applicability beyond the NANOCOLOR® analytical system as an instrument which can be used in all types of application in the laboratory.

Additional features are: processing of non-linear curves, storage of measurement results, warning for values outside the measuring range, possibility of programming the user's own analytical procedures, etc.

Optical construction

light source cuvette filter photo cell Computer display

Light source: lamp, which emits light in the wavelength range 340 860 nm

Cuvette: measurement vessel with the analysis sample

Interference absorbs the entire spectrum of light except for the wavelength

filter: required for the analysis and reflects dispersed light and thermal radiation

Photo cell: converts the light transmitted through the test sample into electric current

Computer: converts the electric Signal into a digital reading using the characteristic data for the respective test

Display: user guidance and display of results

Filters and filter wheel

As the tungsten lamp generates light within the spectral range of 340 - 860 nm, filters are used which only transmit light of the wavelength, which is absorbed by the analysis sample. Light which is practically monochromatic can be attained with the interference filters used in the NANOCOLOR® 300 D. This quality of light ensures a high level of sensitivity and a greater accuracy in the analytical results. The increase in extinction per rise in concentration is also near the maximum value possible.

There are 10 filters fitted in a filter wheel with 12 slots. All of the NANOCOLOR® methods can be evaluated using these filters. The wheel also features two spare filter slots in case the user needs to fit additional filters. Once the method is called up, the filter wheel automatically turns the required filter into the path of the beam.

If new methods are adopted, or if existing methods are modified, other filters can be incorporated into the measurement programme at any time.

Interference filters are heat-sensitive and are metal-coated towards the light source.

When the photometer NANOCOLOR® 300 D is switched on, it automatically performs a filter test. If a deviation is found, the programme asks for a new calibration. Filters which have left the confidence interval, are displayed as <error: filter> (filter change is necessary). In order to prevent wrong measurements, further evaluation of tests which require the defective filter is blocked.
