Guides & Resources

Choose a guide for the task on your bench or in your records. You can convert units, calculate solution concentration, check a material’s identity or trace a certificate to its lot. For a particular vial, use its own specification and lot documentation.

Calculate concentration or convert units

If you know the material mass and final solution volume, use the Concentration Calculator for mg/mL. A mol/L result also needs the molar mass of the same chemical form. If the question is how to express a value in another unit, start with Unit Conversions.

Understand the material

TaskResource
Start with peptide terminologyWhat are peptides?
Find a molecular name or aliasCompound index
Compare identities or formulationsCompound comparisons
Check a term in a reportGlossary

Use names, sequences and CAS identifiers to resolve a name on a document. The melanocortin receptor guide covers receptor terminology. If you are looking at a vial of dried material, use the lyophilised material guide to interpret the fill and appearance terms on the label.

Your questionWhere to start
Which records do I need before preparing a research material?Preparing lyophilised research material covers the chemical form, mass basis and applicable instructions.
The material is difficult to dissolve. What should I check?Preparation troubleshooting helps distinguish the observation from a suspected cause. Use the solvent guide for material-specific compatibility questions.
How do I document portions and later handling?Freeze-thaw cycles and aliquoting covers portion history. Use the research batch and lot log to connect each portion to its source.
What should I record about the container?Packaging and closures covers container condition. The multi-entry container guide covers laboratory access records.
Which storage condition or excursion record applies?Storage and stability covers the material-specific evidence. For an unexpected exposure, record what is known using the temperature excursion guide.

Buy, receive and keep records

Before purchase, use research procurement for evidence requirements and the research catalogue for the listed presentation. After receipt, the storage directory includes a guide to dry material storage records. The research tools directory brings the calculator and record templates together.

For an existing order, order and technical support routes you to the right place for a missing document, delivery question or quality concern.

Use the research references below to follow an experiment or a molecular comparison. Their findings concern the material and experimental conditions described. They do not provide personal administration instructions.
