Sterile | Low Endotoxin | Dual-Buffered | Bench + 5% CO₂ Compatible | Metabolic Support What Is UniBSS™ Wash & Handling Buffer? UniBSS Wash & Handling Buffer is a chemically defined balanced salt solution designed for routine cell washing, dilution, resuspension, and short-term cell handling workflows where maintaining stable environmental conditions is important. In many laboratory procedures, cells are handled both at the open laboratory bench and within CO₂-controlled incubator environments. Buffers that rely on a single buffering system may experience pH drift when environmental CO₂ levels change. UniBSS incorporates a dual-buffer handling system and metabolic-supporting environment designed to help maintain stable conditions during washing and handling steps. The buffer remains fully compatible with common PBS/HBSS workflows while avoiding proteins, animal-derived components, or undefined additives that could interfere with downstream assays. Quick Product Facts Attribute Specification Product Name UniBSS Wash & Handling Buffer Category Balanced Salt Solution Buffer Type Dual-Buffered Handling Buffer Sterility 0.22 µm Sterile Filtered Endotoxin ≤ 0.1 EU/mL Proteins None Animal Components None Metabolic Support Glucose Included Formulation Chemically Defined Format Ready-to-Use Solution CO₂ Compatibility Bench + 5% CO₂ Variants –Ca²⁺/–Mg²⁺ and +Ca²⁺/+Mg²⁺ Storage 2–8 °C Shelf Life 12 Months (Unopened) Intended Use Research Use Only (RUO) Product Overview Routine cell handling steps frequently occur outside tightly controlled incubator environments. During these transitions, buffers that rely solely on environmental CO₂ levels may experience pH shifts when exposed to ambient laboratory air. Changes in pH or metabolic support during wash steps may contribute to: variability between operators reduced cell viability during handling inconsistent wash conditions across workflows buffer switching between bench and incubator environments UniBSS Wash & Handling Buffer is designed to provide a more stable handling environment during routine cell workflows. The dual-buffer system helps maintain stable pH conditions, while the inclusion of metabolic support components helps maintain cell stability during short-term handling steps. Key Features Sterile & Low Endotoxin Sterile-filtered solution with controlled endotoxin levels suitable for sensitive cell handling workflows. Dual-Buffered Stability Designed to support stable pH conditions across both ambient air and 5% CO₂ incubator environments. Metabolic Support During Handling Includes glucose to help support short-term cellular metabolism during washing and resuspension steps. Chemically Defined Formulation Eliminates undefined additives that can introduce experimental variability. Bench + CO₂ Compatible Supports workflows performed both at the bench and in incubator environments without requiring buffer switching. Ready-To-Use Buffer Provided as a sterile solution requiring no preparation or dilution. Typical Applications UniBSS Wash & Handling Buffer may be used in workflows including: routine cell washing flow cytometry wash and resuspension cell pelleting and resuspension media dilution and reagent preparation sample preparation for downstream assays short-term cell handling and transport Researchers should evaluate suitability for their specific experimental systems.

Why Use a Stabilized Handling Buffer? During routine wash and handling steps, cells may experience rapid environmental changes that influence membrane stability and cellular metabolism. Buffers designed to stabilize handling conditions may help reduce: pH drift during bench handling cell stress during wash transitions aggregation during washing steps variability in downstream assays A stabilized handling environment can support more consistent cell preparation across experimental workflows. Quality Control Each batch is prepared under controlled manufacturing conditions and tested to ensure consistent performance. Quality parameters typically include: • pH verification• sterility testing• endotoxin specification• visual inspection for clarity• formulation verification Refer to lot-specific Certificates of Analysis (COA) for detailed quality information.
