Quick answer. Because this listing names eight groups rather than individual chemicals, nothing can be quoted until you say exactly what you need, and the deciding detail is the grade, given with the chemical name and CAS number. AR reagents carry tighter impurity limits than LR; HPLC and spectroscopy solvents are defined by what is absent as much as by the assay; technical grades are for process use, not analysis. The same chemical at a different grade is a different product. Send your list line by line, with pack size and quantity, and get the Safety Data Sheet and transport classification before you agree a delivery date.
Chemicals are listed here as eight groups rather than as individual products: HPLC and GC reagents, high purity acids, high purity solvents, industrial chemicals and solvents, analytical and laboratory reagents, laboratory chemicals, biological stains for microscopy, and pH indicators and solutions. Because no specific chemical, grade or pack size is named in the listing, every order in this range starts with an enquiry. This page sets out what to ask for so that the enquiry gets you a usable quotation first time.
| Group | What it normally covers |
|---|---|
| HPLC and GC reagents | Solvents and mobile-phase components purified for chromatography, where a trace impurity shows up as a peak. Specified by chromatographic suitability, not only by assay. |
| High purity acids | Mineral acids at low trace-metal levels, for trace analysis and digestion work. |
| High purity solvents | Solvents for spectroscopy, molecular biology and analysis, where the specification is defined by what is absent as much as by the assay. |
| Industrial chemicals and solvents | Bulk technical grades for process and workshop use, not for analysis. |
| Analytical and laboratory reagents | Offered in two grades: AR, the analytical reagent grade with tighter impurity limits, and LR, the general-purpose laboratory grade. The grade is the specification, so always state which you need. |
| Laboratory chemicals | General bench chemicals and salts. |
| Biological stains for microscopy | Histology and microbiology stains, where batch-to-batch dye content governs the result. |
| pH indicators and solutions | Indicator solutions and powders, and buffer solutions for meter calibration. |
Acids, solvents and many reagents are hazardous materials, and the paperwork is part of the purchase rather than an afterthought. The product pages in this range do not carry hazard information, so obtain all of the following in writing for each line before you place an order:
| What to state or request | Why |
|---|---|
| Chemical name and CAS number | A CAS number removes all ambiguity about which substance is being quoted. Give it on the enquiry and ask for it on the quotation. |
| Grade | AR or LR for reagents; HPLC or spectroscopy grade for solvents; technical for industrial use. The same chemical at a different grade is a different price and a different product. |
| Assay and impurity limits | Ask for the assay as a minimum percentage and the maximum limits for the impurities that matter to your method. An assay figure alone does not describe a high purity solvent; what is absent matters as much. |
| Enzyme-free status, where it applies | For molecular biology work, confirm in writing that the product is certified free of detectable DNase, RNase and protease activity, and ask for the test method. A description that says activity is present or detectable means the material is unsuitable, so if the wording is ambiguous, get it clarified rather than assuming. |
| Certificate of analysis, per batch | Ask whether a batch COA is supplied as standard. For stains, the dye content and the batch certificate are the specification, because staining behaviour varies between batches. |
| Pack size and container | Glass or plastic, bottle or carboy, and whether a safety-coated bottle is available. Pack size affects both price and transport classification. |
| Shelf life and date of manufacture | Ask for the shelf life and for the remaining shelf life at despatch. For buffers and indicator solutions this is the specification that most often disappoints on arrival. |
| Buffer values and tolerance | For pH buffers, state the values you need, for example 4.00, 7.00 and 10.00, the tolerance, and the temperature at which the value is stated. |
| Import permission | Some chemicals are controlled or require a licence or end-use declaration to import. Check with your own authority before ordering; the obligation sits with the importer. |
Any purity, assay or quality statement quoted for these products is confirmed in writing on the quotation. Ask for the certificate of analysis that supports it rather than relying on a description, and verify the figures against your method's requirement before you order.
The codes in this listing run from C-0001 to C-0008, and the same C prefix is also used for the single-use laboratory items under Consumables, where C-0001 is a plastic petri dish. Always give the chemical name and CAS number alongside any code, so there is no doubt which product is being quoted.
Glassware for handling and storing these chemicals is under Laboratory Glassware, and single-use items under Consumables. Fume hoods, baths and furnaces are under Analytical Lab Instruments. Microscopes and prepared slides to use with the stains are under Microscopes and Slides, and clinical rapid tests under Health Tests. Parent range: Medical Apparatus.
Send a line-by-line list giving, for each item, the chemical name, the CAS number, the grade, the pack size and the quantity, and ask for the Safety Data Sheet and the transport classification with the quotation. Contact Ray Export for prices, availability, documentation and shipping terms.
AR is the analytical reagent grade, with tighter impurity limits; LR is the general-purpose laboratory grade. Both are offered in the analytical and laboratory reagents group, and the grade is the specification, so always state which one you need. Solvents follow the same logic: HPLC or spectroscopy grade for analytical work, and technical grade from the industrial chemicals and solvents group for process and workshop use, never for analysis. The same chemical at a different grade is a different product, so a quotation that omits the grade cannot be compared with any other.
Send an enquiry. The codes C-0001 to C-0008 cover eight groups, and no specific chemical, grade or pack size is named, so every order in this range starts with a line-by-line list. For each line give the chemical name, the CAS number, the grade, the pack size and the quantity, and ask for the Safety Data Sheet and the transport classification with the quotation. Always quote the CAS number alongside any code: the same C prefix is used under Consumables, where C-0001 is a plastic petri dish.
The product pages in this range carry no hazard information, so get the paperwork in writing for each line first. That means a current Safety Data Sheet for the exact product and grade, in a language your staff read, covering hazard classification, handling and storage, incompatibilities, first aid and the spill procedure; the label that will be on the container, with pictograms, signal word and hazard statements; storage and segregation requirements, since oxidisers, acids, bases and flammables must be kept apart; and disposal guidance. If an SDS is not readily available for a line, treat that as a reason to pause.
Often not. Many solvents and acids cannot go by air at all, and others only in limited quantities, so settle the transport question before you agree a delivery date. Ask for each line's UN number, proper shipping name, hazard class and packing group, which determine how the consignment can legally travel; pack size also affects the transport classification. Separately, some chemicals are controlled or need a licence or end-use declaration to import. Check with your own authority before ordering, because that obligation sits with the importer rather than the supplier.
An assay figure alone does not describe a high purity solvent; what is absent matters as much. HPLC and GC reagents are specified by chromatographic suitability, because a trace impurity shows up as a peak, and high purity acids by low trace-metal levels for trace analysis and digestion. Ask for the assay as a minimum percentage and the maximum limits for the impurities that matter to your method. For molecular biology work, ask for written confirmation that the product is free of detectable DNase, RNase and protease activity, and for the test method; if the wording is ambiguous, get it clarified.
For pH buffers, state the values you need, for example 4.00, 7.00 and 10.00, the tolerance, and the temperature at which each value is stated. Ask for the shelf life and the remaining shelf life at despatch, which is the specification that most often disappoints on arrival for buffers and indicator solutions. For histology and microbiology stains, batch-to-batch dye content governs the result, so the dye content and the batch certificate of analysis are the specification; ask whether a batch certificate is supplied as standard before you order.

Listing defects noticed: the eight records C-0001 to C-0008 are product groups rather than individual products, with no chemical, grade or pack size named; the C prefix is also used under Consumables, where C-0001 is a plastic petri dish, so a code alone is ambiguous; the product pages carry no hazard information; and this chemicals range sits under the Medical Apparatus parent.
