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.

- 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 Biostat B-DCU bioreactor station 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.
