Lyophilized Experimentation Vials
Our standard for research compounds
Thoughtful sourcing. Independent testing. Clear documentation. This page sets out how material is selected, what is checked before it is listed, and what records travel with it.
Sourcing standards
Fewer suppliers, held to a written standard
PROC // 01
Vetted manufacturers
We work with a short list of manufacturers who can document their process, their equipment, and their quality systems. Facilities are reviewed before we place a first order, and we ask for the same documentation on every order after that.
PROC // 02
Purity and synthesis standards
Material has to meet a defined identity and purity threshold before it is accepted into inventory. Synthesis routes and analytical methods are agreed in advance, so we know what we are receiving and how it was verified.
PROC // 03
Consistency over time
Each incoming order of material is compared against the reference profile for that product. If it drifts outside the range we accept, it does not get listed, and the product stays out of stock until replacement material clears.
Independent testing
Every product is tested before it is listed
Testing is carried out by third-party laboratories that have no interest in whether a product sells. We post what they return, without editing it, and a product stays unlisted until its report is in hand.
- Identity
- Confirmation that the material matches the specified compound.
- Purity
- Quantified purity, reported as a percentage by the testing lab.
- Impurity profile
- The sample is profiled so any impurities are identified and reported.
Documentation and traceability
Records that follow the product
Every product has a report behind it. The report for a listing is available from its product page, on request, or through the lookup here.
If you keep your own inventory records, the product code is the reference to note. It ties what is in front of you to the exact document the lab issued.
Storage and handling
General guidance for laboratory handling
Temperature-controlled
Hold sealed material in temperature-controlled storage per the product record. Avoid repeated transfers between environments.
Away from light and heat
Keep containers out of direct light and away from heat sources. Original packaging is designed to limit light exposure.
Stability windows
Once prepared in solution for laboratory work, stability is limited. Record the preparation date and observe the window noted on the product record.
Questions
Ordering and accounts
Orders placed on a business day are typically prepared within one to two business days. Domestic transit is usually two to four business days, with cold packaging where the product record calls for it. Tracking is sent when the label is created.
A report is attached to every listed product and can be downloaded from the product card. If you need the report for something you already have, send us the product code and we will send the matching document.
No minimum for standard catalog sizes. Larger or repeat volumes can be quoted directly, and we will confirm availability before taking the order.
Yes. Institutional accounts can be arranged with purchase-order billing and a named point of contact. Contact us with your institution details and we will send the short form to get started.
Tell us within five business days and include photographs of the outer packaging and the container. Damaged or compromised shipments are replaced, or refunded if the product is no longer available.
Major cards, bank transfer, and purchase orders on approved institutional accounts. Payment is taken when the order is confirmed.
