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.

The WatersTM Model 484 Tunable Absorbance Detector (referred to as the Waters 484) is a single-channel tunable ultraviolet/visible (UVNIS) detector designed for high performance liquid chromatography (HPLC) applications.
The Waters 484 monitors the eluent stream from a chromatographic column and detects the presence of sample molecules through optical absorbance at a wide range of specific wavelengths in the ultraviolet and visible spectrum. lt has a usable wavelength spectrum of 190-600 nanometers (nm) although its primary use is in the ultraviolet wavelength range between 190 and 380 nanometers. The maximum sensitivity of the instrument is .001 absorbance units full scale (AUFS).
The Waters 484 can operate as a "stand-alone" unit (with a chart recorder) or with other Waters System modules, such as the Waters 745 integrator.
The Waters 484 offers the following features:
A modular design that allows for easy servicing
Extensive self-calibration to ensure wavelength accuracy and diagnostic routines to verify that the Waters 484 is functioning correctly
Battery backup to retain parameter settings when the detector is powered down or in the event of power interruptions
A deuterium arc lamp
The patented Taper-Cell ® flow cell design which reduces refractive index interference from the absorbance signal
The main components of the Waters 484 include the mechanical parts (such as the front and rear panels and the outer top cover), optics, electronics, and the software.
The optics consist of the optical source and other necessary components that allow the detector to perform absorbance detection.
The electronics of the Waters 484 are digital-based and include hardware such as a front panel keyboard, printed circuit boards and their interconnections. The electronics also include software to control operations such as sensitivity settings, wavelength selection and calibration, and the diagnostics of the detector.
