pH buffers or hydrogen ion buffers are buffer solutions that allow you to adjust your testing system to precisely measure your samples’ unknown pH. Our selection of pH value buffers and pH solution packs can help you feel more confident about accuracies. For best accuracy make sure you perform standardization with fresh buffer solution. Never pour used buffer back into the bottle. Always discard buffer solution after use. Use buffers that frame the pH range of the samples you are testing; match the temperature of the buffer to the temperature of the samples. Calibrate your system before each use or set of uses. We even have buffer pouches to keep your accuracy when you're on the go!

Fittings are a crucial component in setting up your fluid handling system with no leaks, flow restrictions, or costly downtime. Our extensive selection includes barbed fittings for flexible tubing, compression fittings or pipe connectors for rigid tubing, quick-connect couplings, and more. Fittings and adapters are available in sizing to connect anything from microbore tubing up to large pipes and in a variety of materials such as low-cost polypropylene (PP) for general applications to PTFE for corrosive media.

Cleaning Products keep equipment running at peak efficiency, reduce the risk of contamination, and ensure the health and safety of personnel - a necessity for every lab and clean room facility! We recognize the value of laboratory cleaning supplies and offer a complete line of cleaning solutions for surfaces and equipment, skincare products including cleansers and lotions for proper hand cleaning, and cleaning detergents, mops, brushes, and cleanroom wipes

Cleanroom mops are used to clean controlled environment walls and floors. Cleanroom mops have low contamination characteristics and should be laundered and packaged in order to avoid static, residue, and particulates. Cleanroom mop handles can be steel coated with white polyester to ensure complete corrosion resistance.

Safety products matter! They can prevent many injuries before they occur. Safety equipment not only protects your workers but also limits expenses from workers’ compensation and loss of productivity. From personal protective equipment (PPE) to safety instruments, we have a complete line of safety supplies and equipment to help keep you in compliance and maintain a successful safety program
