Alkali Scientific D (+) Glucose [Dextrose Anhydrous], USP Grade, 500 G
D (+) Glucose Anhydrous (USP Grade), 500 g, is a high-purity carbohydrate reagent commonly used in laboratory research, pharmaceutical applications, and biotechnology. Glucose is a critical metabolic substrate for cellular energy production and is essential in the study of cellular respiration, fermentation, and enzyme kinetics. The anhydrous form of glucose is preferred in situations where water content is unwanted or needs to be precisely controlled, making it ideal for dry chemical processes, media preparation, and biochemical assays. This 500 g quantity offers a convenient size for smaller-scale laboratory experiments and applications.
Alkali Scientific Sucrose, 500 G
Sucrose, 500 G, is a high-purity, laboratory-grade chemical widely used in biochemical and microbiological experiments. It is commonly utilized for preparing media, buffers, and solutions in a variety of laboratory applications. Sucrose’s role as an energy source is critical in supporting cellular metabolism, particularly in microbial cultures and enzymatic assays. This 500 G pack size is perfect for laboratories that require smaller quantities for routine analysis or specialized experiments. The high purity ensures consistent, accurate results in biological, chemical, and pharmaceutical research.

Alkali Scientific X Glucoside [5 Bromo 4 Chloro 3 indolyl β D glucopyranoside], 500 Mg
X Glucoside [5 Bromo 4 Chloro 3 indolyl β-D-glucopyranoside], 500 mg is a chromogenic substrate used in molecular biology and microbiology for detecting β-D-glucosidase activity. This substrate reacts with β-D-glucosidase to produce a blue-colored product, which can be easily measured. It is commonly used in enzyme assays and bacterial detection systems, providing a simple and effective method for identifying microorganisms capable of hydrolyzing glucosidic bonds. This substrate is widely used in various biochemical studies, including metabolic pathway analysis and microbial screening, particularly in research involving enzyme activity and genetic engineering.
Alkali Scientific D (+) Trehalose Dihydrate, 50 G
D (+) Trehalose Dihydrate, 50g, is a carbohydrate stabilizing agent used to protect cells, proteins, and enzymes during environmental stress such as dehydration, freezing, and oxidative conditions. Trehalose stabilizes cellular structures, preserves protein functions, and protects sensitive biological molecules from degradation. This 50g bottle is ideal for smaller-scale research projects and biochemical applications where cell protection and sample preservation are critical. It is commonly used in fields such as cryobiology, drug formulation, and the preservation of enzymes and microbial cultures during long-term storage, providing a reliable solution for stabilizing biological samples.
Alkali Scientific Phenol Red Broth with Sucrose 8mL with Durham Tube, 10/Pk
Phenol Red Broth with Sucrose, 8mL with Durham Tube, 10/Pk is a differential culture medium used to detect sucrose fermentation and gas production by bacteria. The medium contains phenol red as a pH indicator and sucrose as the fermentable carbohydrate source. Acid production during sucrose metabolism lowers the pH and changes the medium color from red to yellow, providing a clear visual indication of fermentation. Each tube also includes a Durham tube that captures gas produced during bacterial metabolism. The broth is supplied in 8mL volumes within 13 x 100mm screw cap polycarbonate tubes for reliable handling and contamination control. This medium is widely used in biochemical identification panels for enteric bacteria and other microbial species.
