Negative pressure laminar flow workbench, vertical flow workbench application scenarios (precisely distinguished)
\n1. Vertical flow ultra-clean workbench (positive pressure, only protecting samples, no safety protection) Applicable scenarios
\nIt is only used for pure aseptic and dust-free operations without any biological risks, dust, or toxic aerosols. The main purpose is to protect the samples from environmental contamination.
\nTypical applications:
\nPreparation of common reagents, solution packaging, disassembling and organizing consumables
\nConventional cell culture, passage (non-pathogenic cells)
\nDust-free assembly and testing of electronic and optical devices
\nRoutine aseptic testing of food and water quality (samples without pathogenic risk)
\nDust-free weighing of traditional Chinese medicinal materials and common samples (without dust hazards)
\nStrictly prohibited use
\nNo operations that may cause pollution, aerosols, dust, or pathogenic bacteria are allowed. Otherwise, contaminants will spill and pollute the room and endanger the operators.
\nII. Negative pressure laminar flow workbench (negative pressure, anti-leakage, protecting personnel + protecting the environment + protecting samples) Applicable scenarios
\nFor operations with low microbial risks, dust, volatile substances, and aerosol contamination, the main purpose is to prevent the leakage of samples \/ contaminants and protect personnel and the laboratory environment.
\nTypical applications:
\nPathogen sample processing, strain inoculation, colony picking
\nPre-treatment before PCR nucleic acid testing, virus sample aliquoting
\nToxic, irritating, and trace volatile reagent operations
\nWeighing powder medicines and powder raw materials (to prevent dust dispersion)
\nMedical aesthetics sampling, wound sample processing, infectious sample operations
\nLow-risk biological experiments, contamination sampling operations
\nCore difference summarized in one sentence:
\nVertical flow: Protect samples, clean but not prevent leakage of contaminants, only perform safe and pollution-free operations.
\nNegative pressure laminar flow: Prevent leakage, protect personnel and environment, specifically perform clean operations with contamination \/ biological risks.<\/p>","protected":false},"excerpt":{"rendered":"
