The chemicals offered by Lab Procurement Services are sourced from reliable manufacturers and undergo rigorous testing to ensure their quality and purity. LPS has a team of experts with extensive knowledge of laboratory chemistry who can assist in selecting the appropriate chemicals for a wide variety of research needs.

For example, HPLC solvents and reagent-grade salts are of the highest purity available, and are essential to achieving accurate and reliable results in laboratory research. However, the high cost of these products can be a barrier for many labs with limited budgets. That's where LPS comes in, offering a range of these chemicals at prices that are much more affordable than those offered by many other suppliers.

Please explore our extensive collection of chemicals, conveniently organized into sections by application, as well as other related supplies - containers, glassware, and liquid handling, just to name a few.

 

Before ordering, check that the grade matches the method: ACS and reagent grades meet published purity specifications for general analysis, HPLC and trace metal grades limit the impurities that interfere with those techniques, USP, NF and FCC grades are for pharmaceutical or food work, and technical grade is for non-critical uses. Compare container size and material, since the same chemical may come in glass, amber glass or poly bottles, Cubitainers or drums. Read the Safety Data Sheet for storage, handling and shipping restrictions, ask for a certificate of analysis when your quality system needs one, and note any item marked as shipped cold.

Chemicals: common questions

Can individuals buy laboratory chemicals from LPS?

Chemicals ship only to business addresses, and a company name is required at checkout when the cart contains chemicals. Orders can be placed online, approved business accounts can pay by purchase order, and volume or quote pricing is available through the Contact Us page. Hazardous chemicals cannot be returned, so check the grade and size before you order.

What does 5% sodium hypochlorite mean?

It means the solution contains about 5% sodium hypochlorite, similar in strength to many household bleaches. Labels may express the figure by weight, by volume or as available chlorine, so check which. Sodium hypochlorite solutions lose strength over time, faster when warm or exposed to light, so store them cool and closed, and use fresh stock or verify the concentration for work that depends on an exact value.

What is the difference between anhydrous sodium carbonate and its hydrates?

Anhydrous sodium carbonate contains no water of crystallization, while the monohydrate and decahydrate forms include bound water. That changes the formula weight, so the same mass of each form delivers a different amount of sodium carbonate. When a method specifies one form and you use another, recalculate the mass. The anhydrous form slowly absorbs moisture from air, so keep the container tightly closed.

What is the difference between ACS grade and reagent grade?

ACS grade means the chemical meets or exceeds the purity specifications published by the American Chemical Society in Reagent Chemicals. Reagent grade generally describes a similar high purity suitable for most lab and analytical work, but suppliers do not all use the term the same way. Check the product's specification sheet or certificate of analysis when your method requires a specific limit.
