Description
L 5104 is a laboratory cleaning solution based on pepsin and hydrochloric acid, supplied in a 250 ml DURAN® glass bottle. This ready-to-use formulation is intended for cleaning and maintenance tasks in analytical and electrochemical laboratory environments, particularly where proteinaceous residues need to be addressed on sensor or electrode surfaces. The solution is filled into a high-quality DURAN® glass bottle that offers excellent chemical resistance and clarity for safe handling and visual inspection. Each unit has a net weight of 0,515 kg and is provided as a single piece, making it practical for routine bench-top use. The product originates from manufacturer SI Analytics - a Xylem brand and is manufactured in Germany. Its pepsin/hydrochloric acid composition supports effective removal of organic deposits during electrode care protocols. Laboratories engaged in pH measurement, titration or related analytical work can integrate this cleaning solution into standard maintenance routines. The robust glass packaging protects the contents during storage and transport while remaining compatible with common laboratory workflows and glassware systems.
