What Is Capitol Scientific?

Capitol Scientific is a lab supply and specialty chemicals distributor operating at capitolscientific.com. It sells laboratory equipment, consumables, reagents, and specialty chemicals from more than 300 manufacturers, and it serves organizations that need to stock or restock a lab — research groups, industrial labs, and educational institutions. If you are looking for a single vendor to cover routine lab goods across many categories, this is the kind of site worth checking. If you need a niche instrument or a custom synthesis, you will want to confirm availability before assuming it is stocked.

What the site covers

The catalog is organized around two main pillars, reflected in the site's own headings: Lab Supplies and Reagents & Chemicals. Under lab equipment, the navigation shows a deep, category-by-category structure rather than a short list of featured items. Examples drawn from the site's own menu include:

• Balances and weighing — laboratory balances, accessories, and industrial/lab scales
• Baths and temperature control — boiling, circulating, coliform, shaking, and tissue flotation water baths, plus recirculating chillers and thermostats
• Centrifuges — centrifuges, microcentrifuges, and their accessories
• Data logging — chart recorders, temperature and humidity loggers (including HANNA, Oakton, and Digi-Sense Traceable® lines)
• Density and specific gravity — hydrometers, hydrometer sets, jars, cylinders, racks, and refractometers
• Desiccators and drying — vacuum and non-vacuum glass and plastic desiccators, cabinets, and plates
• Digestion — digestion tubes and Kjeldahl connecting bulbs
• Liquid handling — bottletop dispensers, chemical dispensing equipment, microplate aspirators and pipettors, repeating syringes
• Electrochemistry — conductivity/TDS, multiparameter, ORP/redox, pH, and salinity meters, plus probes, standards, and electrode care
• Evaporation — centrifugal and rotary evaporators, with glassware, chillers, vacuum controllers, and vacuum pumps
• Containment and heating — fume hoods, glove boxes and gloves, and furnaces (ashing, box, muffle, tube) with controllers
• Gas and measurement — nitrogen gas generators, anemometers, flow meters, and calipers

Animal science products, including animal restrainers and Drosophila products, also appear in the equipment navigation.

Who it is built for

The mix of categories points to buyers who order across disciplines rather than from a single instrument brand: a lab manager replacing glassware and electrodes, a teaching lab stocking water baths and balances, or an industrial QC group buying reagents and specialty chemicals alongside equipment. The site's own framing — "your complete source for lab supplies & specialty chemicals" and "building trust through partnership" — positions it as a broad-line distributor rather than a manufacturer.

Account and ordering features

The site exposes several procurement-oriented entry points in its header and customer area:

• Login / Register
• Store Locator
• Procurement Portals
• Request COA (certificate of analysis)
• Quick Order
• Customer Center

The presence of procurement portals and COA requests suggests the site is set up for institutional purchasing workflows, where buyers need documentation and punch-out or portal-based ordering. A phone line for assistance is listed as 512.836.1167.

Practical notes before you buy

• JavaScript is required. The site states that JavaScript must be enabled (or the browser upgraded) to view it, so plan for a modern browser.
• Discontinued items exist. A "Manufacturer Discontinued Items" section is linked in the site's own navigation (for example, a PRO Scientific discontinued-items page), which is a reminder to verify current availability on any specific SKU rather than relying on a category listing.
• Pricing is not shown in the available material. No price signals or payment platforms appear in the source data, so treat pricing, minimums, and payment terms as things to confirm through the site or a sales representative.
• COA and documentation. If your workflow requires certificates of analysis for reagents or chemicals, the "Request COA" link is the relevant starting point.

How to decide whether to use it

Use capitolscientific.com as a candidate vendor when you need many lab categories from one source and value procurement features like quick order, portals, and COA requests. Verify specific product availability, pricing, and lead times directly, especially for items that may sit in discontinued lines. If your need is a single specialized instrument or a made-to-order chemical, compare against a manufacturer-direct or specialty supplier before committing.
