NPD Mini PCR Hood
Model: NPD-232 · PCR-2.5 | DNA Carryover Containment & PCR Setup Workstation
The NPD-232 Mini PCR Hood is a compact, partially recirculating vertical-downflow workstation for pre-PCR preparation. HEPA H14-filtered airflow and UV decontamination help protect molecular-biology workflows against airborne particles and DNA carryover contamination.

Compact Protection for Sensitive PCR Preparation
Previously amplified DNA can contaminate new PCR reactions through airborne particles or residue on laboratory surfaces. The NPD Mini PCR Hood creates a controlled preparation area with HEPA-filtered vertical airflow, an inward air barrier and UV-based decontamination to help minimise unwanted carryover during PCR master-mix and reaction assembly.
Its compact benchtop footprint, glass-fronted work zone, LCD controller and removable stainless-steel worktable make it practical for molecular diagnostics, genomics and academic or research laboratories.

How the Mini PCR Hood Works
Four stages for contamination-conscious PCR setup.
Prepare the work area
Clean the removable worktop and set up a dedicated pre-PCR workspace.
Start filtered airflow
The blower circulates air through the main HEPA H14 filter, supplying vertical downflow.
Prepare PCR reactions
Carry out master-mix assembly and reagent handling within the controlled work zone.
Decontaminate between runs
Use established DNA-cleaning procedures and UV only when the work area is unoccupied.
HEPA-Filtered Vertical Downflow
Room air enters through the front opening, creating an inward air barrier. The blower delivers filtered vertical downflow across the worktable. Approximately 70% of air recirculates through the main HEPA H14 filter while 30% passes through a separate exhaust filter rated at 99% gravimetric efficiency.
Main HEPA H14 filtration is specified at 99.995% collection efficiency at 0.1–0.2 µm MPPS.
Simple, Reliable Laboratory Operation
The LCD digital controller provides soft-touch controls for the centrifugal blower, fluorescent work light and UV lamp. UV exposure can help reduce residual DNA contamination between work sessions, alongside approved physical cleaning and DNA-decontamination procedures.
Tempered-glass panels, a hinged window and 1,200 lux task illumination support visibility and accurate sample handling.
Applications & Laboratories
Mini PCR Hood FAQs
What is the NPD Mini PCR Hood used for?
It provides a dedicated, contamination-controlled area for PCR setup, master-mix preparation and handling molecular-biology samples.
Which filter does the NPD-232 use?
The main filter is HEPA H14, specified at 99.995% collection efficiency at 0.1–0.2 µm MPPS. The exhaust filter is separately specified at 99% gravimetric efficiency.
What are its internal dimensions?
The work chamber measures 745 × 435 × 500 mm (W × D × H). Overall dimensions are 815 × 615 × 931 mm.
Does it include UV decontamination?
Yes. It includes UV-lamp control, but the supplied PDF does not give the UV wavelength or lamp wattage.
Can it replace a biological safety cabinet?
No. It is intended for non-hazardous pre-PCR preparation and is not a substitute for a Class II Biological Safety Cabinet or a chemical fume hood.
Is a stand included?
A powder-coated MS tubular stand is listed as an optional accessory.
