Quality
HPLC ≥99%. Identity confirmed. Lot on every vial.
Every batch is checked against the published CAS, formula and mass before it leaves Southampton. Plain packaging. Pre-mixed as standard.
HPLC purity
Peptides in this catalogue are released at ≥ 99% purity by HPLC, with identity confirmed against the expected mass.
Lot on the vial
Every vial is marked with a lot number. Keep it with your notes so the bottle matches the order.
Published identifiers
CAS numbers, formulae and sequences are on each product page. You can check the compound before you buy.
Packed for the bench
Pre-mixed as standard. Handle, reconstitute, and dispose of under your laboratory SOP.
How a batch is released
Identity is confirmed against the expected mass for the published formula or CAS number on the product page. Purity is assessed by HPLC at 99% or greater. The lot printed on the vial is the record for that bottle — not a generic claim copied across SKUs.
Reconstitution, in-use handling and disposal follow your laboratory SOP. Solent Peptides documents what is in the vial; we do not design your experiment. HPLC ≥99% is a batch-release specification we apply — it is not a licensed-medicine standard, not a guarantee of fitness for any biological use, and we are not currently enclosing a paper certificate in every box.
Longer notes: what HPLC measures, how to read a COA, and why batch numbers matter.
