FAQ
General Questions About Corix Labs
What is Corix Labs?
Corix Labs is a UK-based supplier of laboratory research reagents specialising in high-purity synthetic peptides and related scientific materials. The company focuses on supplying compounds suitable for controlled laboratory research environments such as universities, analytical laboratories, and professional research facilities.
All materials supplied by Corix Labs are designated Research Use Only (RUO) and are intended exclusively for scientific investigation and laboratory experimentation.
Who are Corix Labs products intended for?
Products supplied by Corix Labs are intended for use by trained professionals working within laboratory research environments. This includes academic institutions, biotechnology laboratories, analytical chemistry facilities, and other organisations engaged in scientific investigation.
What does “Research Use Only” (RUO) mean?
The Research Use Only designation indicates that a product is supplied strictly for laboratory research and scientific investigation. RUO materials are not approved for diagnostic, therapeutic, or clinical use.
Are Corix Labs products intended for human or medical use?
No. All products supplied by Corix Labs are intended exclusively for laboratory research. They are not intended for human consumption, medical treatment, diagnostic use, or therapeutic applications.
Do you sell pharmaceutical or medical products?
No. Corix Labs supplies research reagents only. The company does not supply pharmaceutical products, prescription medicines, or medical treatments.
Do you supply GLP-1 peptides?
No. Corix Labs does not supply GLP-1 peptides. The company focuses solely on laboratory research reagents intended for scientific investigation.
How can I contact Corix Labs for further information?
Customers can contact the Corix Labs support team through the website contact page for assistance with products, orders, or documentation enquiries.
Quality, Testing and Analytical Verification
Are all batches tested?
Yes. All batches supplied by Corix Labs undergo analytical verification. Testing is conducted to confirm compound identity and to ensure appropriate documentation accompanies each batch.
What analytical methods are used to verify peptides?
Common analytical methods used in peptide verification include chromatographic analysis and mass spectrometry. These techniques help confirm compound identity and provide information about the composition of the material.
What is a Certificate of Analysis (COA)?
A Certificate of Analysis is a document that summarises analytical testing performed on a specific production batch. The document typically includes batch identification, testing methods, and analytical results.
Why is independent laboratory testing important?
Independent testing provides an additional level of transparency because analysis is performed by a laboratory separate from the manufacturer. This helps ensure objective verification of analytical results.
What is HPLC testing?
High Performance Liquid Chromatography (HPLC) is a widely used analytical technique that separates compounds within a sample. In peptide analysis, HPLC can be used to examine the composition of the material and confirm analytical characteristics.
What is LC-MS testing?
Liquid Chromatography Mass Spectrometry combines chromatographic separation with mass analysis. This method helps confirm molecular mass and compound identity.
Product Handling and Storage
Why are peptides supplied in lyophilised form?
Lyophilisation is a freeze-drying process that removes moisture from compounds. Supplying peptides in lyophilised form can improve stability during storage and transportation.
What is lyophilisation?
Lyophilisation is a process where a compound is frozen and then dried under reduced pressure. The ice present in the material transitions directly from solid to vapour in a process known as sublimation.
How should lyophilised peptides be stored?
Storage conditions vary depending on the compound. Many lyophilised peptides are stored in cool, dry environments prior to preparation for laboratory use.
What is reconstitution?
Reconstitution is the process of dissolving a lyophilised compound in an appropriate solvent to produce a solution suitable for laboratory research.
What solvents are commonly used for reconstitution?
Solvent selection depends on the chemical properties of the peptide and the requirements of the research protocol. Researchers determine solvent suitability based on laboratory procedures and experimental design.
How can contamination be avoided during preparation?
Researchers typically use sterile laboratory consumables, clean preparation environments, and controlled laboratory practices to minimise contamination.
Why are aliquots used in laboratory preparation?
Aliquoting allows a solution to be divided into smaller portions. This reduces repeated handling of the primary sample and helps maintain reagent stability.
Why should freeze–thaw cycles be minimised?
Repeated freezing and thawing can affect the stability of certain compounds. Laboratories often minimise freeze–thaw cycles by preparing aliquots for individual experiments.
Orders, Delivery and Payment
What payment methods does Corix Labs accept?
Corix Labs only accepts bank transfer payments. We do this to keep our prices as low as possible because card processors for these product types have extremely high processing fees.
Is payment required before shipment?
Yes. Orders are processed once payment has been successfully received and confirmed.
How long does order processing take?
Orders are typically processed same day for payments received before 11am for which confirmation has been received.
Do you ship internationally?
We ship from the United Kingdom to the United Kingdom and Western Europe only. If your address is outside the United Kingdom, it is your responsibility to check before ordering that the items you are buying may lawfully be imported into your country. You are the importer of record, so any customs duty or import VAT charged on arrival is payable by you. If a parcel is seized, detained, destroyed or returned by customs, we do not reship, replace, or refund it. See our Delivery Information and Research Use Only Terms.
Are shipping services tracked?
All deliveries are tracked so customers can monitor shipment progress and estimated delivery times.
What happens if a shipment is delayed?
Delivery times are estimated by the courier service. In the event of delays, customers can use the tracking information provided or contact support for assistance.
What should I do if my order arrives damaged?
If a shipment arrives damaged, customers should contact Corix Labs support and provide details of the issue so it can be reviewed.
Can orders be cancelled?
Orders may be cancelled prior to dispatch. Once shipped, orders cannot be cancelled because they have entered the courier delivery process.
Do you accept returns?
Due to the specialised nature of laboratory reagents, returns are generally not accepted once products have been delivered.
Why are returns not accepted?
Once a reagent leaves the supplier’s controlled environment it cannot be verified that appropriate handling conditions have been maintained.
Research Compliance and Scientific Documentation
What is batch traceability?
Batch traceability refers to the ability to identify and track a specific production batch of a reagent throughout its lifecycle.
Why is traceability important?
Traceability allows researchers to identify the exact material used in an experiment and link it to analytical documentation.
What is a batch number?
A batch number is a unique identifier assigned to a specific production run of a compound.
Why is documentation important for research?
Documentation helps laboratories maintain accurate records of the materials used during experiments.
What is research reproducibility?
Reproducibility refers to the ability for experiments to be repeated and produce consistent results under similar conditions.
How do suppliers support reproducibility?
Suppliers support reproducibility by maintaining batch traceability, providing analytical documentation, and ensuring transparent reporting of material characteristics.
What regulatory responsibilities do laboratories have?
Laboratories are responsible for ensuring that research materials are handled and used in accordance with institutional policies and applicable regulations.
Why is transparency important in reagent supply?
Transparency helps researchers understand the characteristics of the materials they are using and supports responsible scientific practice.
