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.

Einführung
Die Visko-Elastizität von Flüssigkeiten und "weichen" Feststoffen kann prinzipiell auf zwei Arten untersucht werden; entweder man gibt eine Deformation vor und mißt die dazu notwendige Kraft (CR-Modus, deformationsgesteuert) oder man gibt die Kraft vor und ermittelt die resultierende Deformation (CS-Modus, kraftgesteuert). Die Betriebsart CS bietet einige entscheidende Vorteile:
- Messungen können im linear viskoelastischen Bereich durchgeführt werden, wodurch die Mikrostruktur der Probe unzerstört erhalten bleibt.
- Applikationen wie Tropfnasen von Lacken oder Sedimentation einer Suspension können simuliert werden.
- Extrem hohe Auflösung bei kleinen Spannungen und Fließgrenzen.
Meßprinzip
Der Motor der Geräte, eine Eigenentwicklung von HAAKE, zeichnet sich durch eine extrem niedrige Trägheit aus. Die Leistung des Motors wird über ein spezielles, nahezu reibungsfreies Luftlager auf den Sensor und somit auf die Probe übertragen. Verfügbar sind Meßgeometrien vom Typ Platte-Platte, Platte-Kegel und koaxiale Zylinder. Die aus der angewandten Kraft resultierende Deformation der Probe wird dann gemessen. Diese Messung erfolgt über einen digitalen Meßaufnehmer mit einer Empfindlichkeit von 1 Million Impulsen pro Umdrehung. Dadurch können selbst kleinste Fließgrenzen und minimale Deformationen untersucht und gemessen werden.
