Status, terms of delivery and payment
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.

These devices are intended for use by operators experienced with the methodology, during those parts of in vitro diagnostic enzymatic or quantitative or qualitative analysis procedures which require measurement of light transmission through reagents at wavelengths in the visible and ultraviolet regions of the electromagnetic spectrum.
The Model 24 is capable of measuring light at wavelengths from 340 to 700 nanometers (190 to 700 nanometers with optional deuterium source).
The Model 24 Spectrophotometer are double-beam, digital-reading or recording instruments which can make absorbance, concentration, percent transmission and differential absorbance measurements. Quantitative and qualitative analysis and reaction-rate studies are easily accomplished. Specialized techniques such as automatic sampling and batch sampling, are possible with addition of easily mounted accessories.
The Model 24 Spectrophotometer is housed in a compact case with front and rear panel controls, and a four-digit display. Major design features of the instrument include: one source (tungsten), monochromator, detector, large sample compartment, fixed slit, solid-state circuitry, a fixed aperture, 340 to 700-nanometer operating range, and readout in absorbance, concentration, and differential absorbance modes.

PHOTOMETRIC READOUT
Digital Display
Four-digit digital display, 0 to 2 A, or 0 to 8000 counts in concentration. In addition, 0 to 200%T an the Model 26.
Recorder
100-millivolts per absorbance unit or 100 millivolts per 100%T on the Model 26.
Differential
