Dimethyl silicone oil is a polydimethylsiloxane fluid with a kinematic viscosity of 100 cSt at 25 °C. It is a colorless to light-yellow, chemically inert oil used in laboratory applications as a reagent, viscosity standard, lubricant, and formulation component.

• Provides consistent 100 cSt viscosity at 25 °C
• Chemically inert and low volatility for stable performance
• Good thermal and oxidative stability across common lab temperatures
• Hydrophobic and lubricating properties suitable for coatings and seals
• Clear liquid with typical density ~0.96 g/cm³ for formulation use
• Available in small-volume packaging suitable for research labs

Alkali Scientific Penicillin G Sodium Salt [Benzyl Penicillin Sodium Salt], 25 G

Penicillin G Sodium Salt in its powdered form is a potent antibiotic widely used in research to treat infections caused by gram-positive bacteria. This 25 g formulation is used in laboratories for preparing solutions that are tested for their antibacterial properties. The antibiotic functions by inhibiting bacterial cell wall synthesis, which is crucial for bacterial survival. In research applications, Penicillin G is used to test bacterial susceptibility and antimicrobial resistance in microbial cultures. It also serves as a reference standard in testing new antibiotic compounds. Penicillin G is frequently used in microbiology labs to help control bacterial growth in experiments and for therapeutic uses in clinical medicine.
