Ammonium Hydroxide, Reagent, ACS is a solution of amonia in water. Aqueous amonia, as it's otherwise known is used as a complexant and base in qualitative inorganic analysis. It becomes a deep blue color with copper solutions. Also used to dissolve silver oxide residues, such as the ones formed from Tollens' reagent. It is also commmonly used in numerous household cleaning agents, such as window cleaning formula. As an ACS grade Reagent, Spectrum Chemical manufactured Ammonium Hydroxide is used as the quality standard against which other substances are graded and has met the toughest regulatory standards for quality and purity.

Sodium Hydroxide, Low Chloride, Pellets, Reagent, ACS is commonly known as Caustic soda. This inorganic compound is water soluble, as well as in ethanol and methanol. The dissolution of solid Sodium Hydroxide in water creates a highly exothermic reaction. One of its many characteristics is that it's a deliquescent alkali and absorbs carbon dioxide and moisture from the air. Used in many industries, most notably in the manufacture of pulp, paper, textiles, drinking water, detergents and as household drain cleaner. As an ACS grade Reagent, Spectrum Chemical manufactured Sodium Hydroxide is used as the quality standard against which other substances are graded and has met the toughest regulatory standards for quality and purity.

Sodium Carbonate, Anhydrous, Powder, Reagent, ACS also known as washing soda, is a white powder without smell that readily absorbs moisture present in the air. Glass production is by far the biggest source of use for it. Acting as a flux for silica it enables the melting point to be lower, facilitating the glass making process. As a sodium salt it makes for a great electrolyte and is often used as one in chemistry. It is also used as household water softener, food additive and in taxidermy. As an ACS grade Reagent, Spectrum Chemical manufactured compound is used as the quality standard against which other substances are grade and has met the toughest regulatory standards for quality and pureness.

Code: 250-LT-RF-S-L. Create a perfect ergonomic system in the lab with FlexFit®, StarStop®, and a Biotix LFE® or Rainin LTS® pipette. Low cost option to get high-quality tips 960 tips on the lab bench using the same surface area as 1 rack Re-sealable bag is available in both sterile and nonsterile formats Color-coded snap cards allow for quick identification The product is fully recyclable and contains no contaminating cardboard or paper Inserts are easy to transfer to an Optimus empty rack Full multi-channel and single-channel LFE® and LTS® pipette compatibility Light Insertion Force FlexFit® sealing technology requires minimal insertion force to generate consistent seals that users can trust with every tip. Light Ejection No matter how tips are applied, xTIP4™ pipette tips will always eject at the same light force. The StarStop® feature works with LTS-style pipettes to create a strong seal in the same location, every time. Low Binding Biotix low retention technology reduces the amount of sample lost in the tip when pipetting. Great for use with loading dyes, proteins, and DNA to increase an experiment's accuracy and yield. Clean Delivery These tips are engineered with the Blade® ratio to reduce hanging droplet formation when dispensing a sample. This limits the need for tip touch off on plate wells or tubes, saving time and reagent. Certifications: ISO 9001:2015, Certified free of Dnase, Rnnase, Endotoxins/pyrogens, and PCR inhibitors. Sterilized product is certified to 10?³ SAL (4800 per CS )

HEPES, Biological Buffer is as it's name suggests, a buffering agent. It's a zwitterionic organic chemical that is one of the '20 Good's buffers.' Because it's better at maintaining physiological pH despite changes in carbon dioxide, it is widely used in cell culture. It has a decrease of water dissociation with falling temperature, this is especially relevant when working at low temperatures as it maintains enzyme function and structure. That said, it is important when working with HEPES for that particular purpose to keep the HEPES-containing solution in darkness as much as possible.
