Wyatt Technology GPC Detector System w/ DAWN WD3 MALS Detector & ViscoStar Differential Viscometer

We verify various instrument functions individually and together, performing necessary repairs or maintenance to bring the instrument to our quality standards..

Wyatt Technology DAWN Multi-Angle Light Scattering Detector:

• We verified the proper initialization of the detector upon startup.
• We check seamless communication between the detector and Astra control software.
• We verified the DLS detector operation.
• We assessed the temperature range and ensured that stabilization was consistently maintained.
• We check and confirm that the detector system properly zeroes out.
• We tested the injection of bovine serum albumin with Agilent HPLC System

Wyatt Technology ViscoStar Differential Viscometer:

• We verified the proper initialization of the detector upon startup.
• We checked seamless communication between the detector and Astra control software.
• We confirmed that the detector system properly zeroes out.
• We tested the difference in signal detection from Dl water versus isopropanol, assessing the detector's sensitivity to different solvent compositions.
• We confirmed the functionality of the system's leak detection feature to identify any potential leaks.
• We tested the injection of bovine serum albumin with Agilent HPLC System

We invite you to visit our facility for an on-site demo, or feel free to request a virtual Zoom demo of the instrument you are interested in.

Warranty Terms:

• The instrument comes fully warrantied for both parts and labor.
• The customer should retain all packing materials during the warranty period.

• Make sure the instrument is properly packed for shipping and will arrive safely. If the instrument is large, request to have it packed in a wooden crate.
• Confirm that there is no physical damage or any misaligned internal components.
• Ask what accessories are included.
• Ask how long the warranty is and what it covers.

Here is what our technical team tests so you can request something similar and ensure your instrument will be fully functional.

We recommend inspecting the instrument in person or requesting a virtual demo; this will allow you to evaluate the condition and performance of the instrument you are considering purchasing.

• This is a common model, and we generally stock multiple instruments, accessories, and many replacement parts to back up our warranty.

We acknowledge that sometimes you can purchase this model instrument elsewhere, possibly for less.

Here are some of the reasons for our price.

• We may offer longer warranty terms.
• We cover shipping costs during the warranty period. (Customer is required to save packing materials for the duration).
• We have to have technical staff that can do the testing/repairs and after-sales support if there are any issues.
• We invest considerable time into the testing and service of each instrument we sell.
• We have to purchase various testing supplies (often expensive) to perform testing.
• We have to purchase any missing required accessories to make the instruments complete.
• We have to procure and stock service parts to support our warranty.
• We have extensive experience packing sensitive instruments. See the shipping section in the website menu for info on how not to pack.
• We guarantee that the instrument will be functional.

• If you are a US or Canadian customer, we are likely already a registered vendor in your University's vendor system. This would greatly expedite the process of PO approvals and get this instrument into your lab faster.
• POs are accepted from US and Canadian universities.

• We can ship within a few days to two weeks. Shipping time depends on the current demand for our instruments. Members of our sales team will be able to offer current delivery estimates.

• All instruments shipped within the USA and internationally are fully insured. This applies as long as we are the shipper and handle shipping arrangements.
• If the buyer handles shipping, then shipping insurance responsibility falls to the buyer; we highly advise that the buyer obtain shipping insurance from their carrier.

Packing

• Most larger instruments ship in fully enclosed ISPM15-certified wooden crates with proper padding underneath, and the sides have moving components braced.
• Accessories are packed safely in boxes with padding and then safely packed inside the crate.
• We may not use a crate for local deliveries to save you money *if delivered by us.
• We often use “tilt’ & “shock” indicators on the crates to ensure the crate has not been excessively tilted and dropped where equipment may suffer damage.
• Photos are taken during the packing process to make sure nothing is missed.

USA/Canada Shipping

• Within the US and Canada, we will ship via selected freight carriers. We do not use low-price/high-damage carriers as we want the equipment to get safely to you.

International Shipping

• Internationally, we will only ship via Air Freight or Air Parcel (such as UPS or DHL), which provides reliability, no exposure to Ocean weather, and timely delivery.
  We have extensive experience packing and shipping fragile instruments globally.

Our experience and process

• We have safely packed and shipped thousands of sensitive analytical instruments.

A lot…and it is undoubtedly worth it, and here is why. Feel free to ask for feedback from hundreds of customers who bought from us.

• You will pay less than half vs. buying a new instrument. Why not spend leftover funds on another instrument for your lab?
• You will get our standard warranty, plus, when available, an option to obtain an extended warranty agreement.
• Know that your instrument was tested and working the day it left our facility and is covered if there are faults.
• Get extra peace of mind by adding an extended warranty or service agreement when such an option is available.

• Well, this one is easy: buying a pre-owned instrument is great for the planet; you are reducing unnecessary waste, CO² output, and water use that would be used during the manufacturing process.
