WHY DO CUSTOMERS MAKING CRITICAL LAB PURCHASES CHOOSE TO ORDER CHROMATOGRAPHY SYSTEMS FROM US?

 

  They want to ensure all pump heads, seals, and check valves have been tested for consistent pressure generation and stable flow rates, preventing gradient drift, pulsation, or baseline instability.


  They want peace of mind knowing the system has been fully flushed, primed, and run through gradient and collection tests under realistic purification conditions.


  They want to ensure expected retention times for verification standards fall within tolerance, confirming that solvent routing, column integrity, and pump calibration are functioning within manufacturer specifications.


  They want to avoid baseline instability, incorrect solvent mixing, or poor fraction resolution caused by untested pumps, misconfigured detectors, or software timing errors, issues that often go undetected until critical purification work is lost.


  They want assurance that fraction collectors, diverter valves, and switching modules operate correctly under pressure and respond precisely to signal triggers, avoiding miscollection or cross-fraction contamination.


  They want to ensure the UV lamp has been checked for remaining life and replaced if needed, so the system generates good data and is ready to use the same day it is installed.


  They want peace of mind, knowing their instrument is backed by a warranty from a company that can stand behind it.

What supplies do I need?

You will need the consumables starting out:

 

Can I view the CombiFlash EZ Prep UV Flash Chromatography System in person at your facility or do a live Zoom demo before it is shipped to me?

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.

 

What about the warranty? Installation, training, maintenance?

Warranty Terms:

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

 

What should I watch out for when buying a CombiFlash EZ Prep UV Flash Chromatography System used/pre-owned from another lab?
  • 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 verified the power supply and initialization to ensure stable startup and operation.
  • We calibrated the touch screen interface for accurate responsiveness and user control.
  • We assessed the accuracy of arm movement and confirmed smooth, precise positioning.
  • We confirmed the RFID column detection for proper identification and communication.

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.

 

Do you have a CombiFlash EZ Prep UV Flash Chromatography System on hand?
  • This is a common model, and we generally stock multiple instruments, accessories, and many replacement parts to back up our warranty.

 

I found it elsewhere for less. What goes into your price?

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.

 

This procurement is for a University or College. Are purchase orders with NET terms accepted?
  • 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.

 

How fast will you ship?
  • 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.

 

Will my instrument be insured during shipping?
  • 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.

 

How do you pack? Have you packed and shipped CombiFlash EZ Prep UV Flash Chromatography System Instruments in the past? Do you ship Internationally?

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.

 

How much will I save buying it pre-owned, and is it worth it?

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.

 

Sustainability
  • 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.
