Esco Ascent Opti 3ft Ductless Fume Hood Model SPD-3A2
Economical, Advanced, and Ergonomic Ductless Fume Hood
The Esco Ascent Opti 3ft Ductless Fume Hood (SPD-3A2) delivers high-performance filtration and ergonomic design at an affordable price. Ideal for general lab work, mixing, dilution, and buffer preparation, this hood provides superior operator protection and airflow efficiency without requiring an external duct system.
Featuring Nanocarb filters, the SPD-3A2 removes chemical fumes efficiently and recirculates clean air back into the laboratory. Its ergonomic sloped front, frameless acrylic panels, and spill-retaining worktop enhance comfort, visibility, and safety for operators.
