Laboratory supply — analytical consumables, reagents and instruments
Supplies for the analytical bench.
Columns, consumables, reagents and instruments for peptide research laboratories. Every listing sets out what the item is for, what it does not establish, and what else the method requires.
A laboratory supply catalog. No peptides, pharmaceuticals or compounded products are sold here, and nothing listed is intended for administration to humans or animals.

Research method overview
The full guide Six workflows, six bounded questions
Each workflow answers one narrow question under conditions the laboratory defines. None of them establishes that material is safe, sterile or fit for any use.
01
Identity
Does the observed mass agree with the expected molecular mass?
- Method
- Mass spectrometry
- In-house?
- A mass spectrometer and a qualified method are prerequisites. This catalog covers sample preparation only — the instrument, the run and the interpretation belong to the laboratory or its contract facility.
Purity
What chromatographic area profile does the defined method produce?
- Method
- Reversed-phase HPLC
- In-house?
- Needs an HPLC with a suitable detector, reference materials where the method calls for them, and system-suitability limits. Columns and consumables are stocked here; the instrument, solvents and acid modifiers are not.
Content
What concentration estimate does the selected method produce?
- Method
- Weighing, BCA and UV
- In-house?
- Within reach of a suitably equipped laboratory. Calibration currency, controls and method suitability determine whether the result means anything.
Endotoxin
Does a validated LAL method detect endotoxin at the stated threshold?
- Method
- LAL gel-clot
- In-house?
- For qualified laboratories following the lysate manufacturer's instructions under a validated, sample-appropriate method. These items are consumables, not a release test.
Sterility
Does a qualified culture method detect growth under the stated conditions?
- Method
- Culture in two media
- In-house?
- Requires aseptic facilities, trained staff and a validated method. An incubator and prepared media are the easy part and are not a compendial test on their own.
Quick screen
Does the sample show an unexpected TLC pattern?
- Method
- Thin-layer chromatography
- In-house?
- A bench technique needing only a chamber and a lamp. The comparison is qualitative and rests on the reference material and solvent system chosen. Developing solvents and stains are not stocked here.

Listings say what the method still requires.
The catalog covers consumables, reagents and bench instruments. Facilities, trained staff, controls, method validation and regulatory obligations sit with the laboratory, not with the supplier.

FAQ
Questions, answered
Which of these workflows need instruments or facilities I may not have?
Mass and chromatographic work need the corresponding instrument. Endotoxin and growth detection need qualified facilities, trained staff, controls and a validated method appropriate to the sample. What is stocked here is consumables and bench equipment — not a validated laboratory process.
How is a kit priced?
A kit is priced below the sum of its parts, and the saving appears on the kit page. It groups what one workflow consumes; it is not a validated method.
Which column should I choose?
It depends on the instrument, the analyte, pressure limits and the selectivity the method needs. The three dimensions listed are common starting points rather than a guarantee of resolution. Send the instrument model and method requirements and we will talk it through before you order.
Can I order solvents or stains with my consumables?
No. Flammable, corrosive and toxic chemicals are outside this catalog — acetonitrile, TFA, formic acid and ninhydrin stain included. A chemical distributor set up for hazardous-materials carriage is the right source. Everything stocked here moves by standard services.
How fast do orders ship?
We confirm the dispatch date on your invoice before you pay. Orders over $300 ship free.
Can I return something?
Unopened instruments and consumables come back within 30 days — email first for return instructions. Reagents, media and opened consumables cannot be returned, since their integrity cannot be verified once they leave. Damaged, defective or incorrect goods are replaced or refunded if reported within 7 days.
Do you accept purchase orders?
Yes, for universities, companies and contract laboratories. Accounts and credit terms are subject to approval, and holding an account changes nothing about labelled intended use or shipping restrictions.
Are the reagents for diagnostic use?
Nothing here is for diagnostic use. Reagents are labelled for laboratory research unless a product page documents a different status from the manufacturer, and no item should be used outside that labelling.
