Benchtop PCR Cabinet

What is the Benchtop PCR Cabinet?

A benchtop PCR cabinet is a small enclosure that fits on an existing bench for single-operator reaction set-up. It offers UV decontamination and optional HEPA flow in a compact footprint and low noise.

Overview

The cabinet is typically 500–900 mm wide and 500–600 mm high, sized for one operator working with a pipette, a rack and a small cooler block. It may be a dead-air design or a small HEPA laminar flow unit with downflow at 0.3–0.5 m/s, and it includes a 254 nm UV lamp with a timer and interlock. Interior lighting is provided, and the front may be a hinged panel or a small sash. Because it is compact, the internal working height and depth limit the equipment that fits, so multi-channel pipettes and large racks may be awkward. The cabinet suits small laboratories, teaching and diagnostic benches where a full clean bench is not needed, provided that PCR areas are still separated and cleaning is thorough.

How does it work?

A PCR cabinet reduces the chance that stray DNA or RNA contaminates a reaction or that amplified product carries over into the next sample. Two mechanisms are used. A laminar flow PCR cabinet passes HEPA-filtered air across the work surface at 0.3–0.5 m/s, sweeping particles and aerosols away, and gives ISO 5 cleanliness at the work point. A dead-air or still-air workstation instead encloses the work but does not supply filtered air, relying on limited air exchange, UV irradiation and careful technique to reduce contamination. Both types usually include a 254 nm UV lamp for surface decontamination between sessions, and many include a timer and an interlock so that UV cannot run while the sash is open. Some models are ducted for vapour removal. Regular cleaning, separate pre- and post-PCR areas and dedicated equipment remain essential.

What are the key features?

• Compact bench-mounted enclosure
• Dead-air or small HEPA downflow option
• 254 nm UV lamp with timer and interlock
• Interior lighting for pipetting
• Widths 500–900 mm, one-operator use
• Hinged front panel or small sash

What are the technical specifications?

A typical benchtop pcr cabinet configuration offers type of Benchtop PCR cabinet, air supply of Still air or HEPA downflow, downflow velocity of 0.3–0.5 m/s (HEPA models), UV lamp of 254 nm, timed, width of 500–900 mm and height of 500–600 mm. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The Benchtop PCR Cabinet is used in single-operator PCR set-up, teaching and training, small diagnostic laboratories and field or satellite laboratories. Across the wider PCR Cabinets class, laboratories also deploy it for PCR reaction set-up, nucleic acid extraction and handling and molecular diagnostics.

Which standards and certifications apply?

Relevant standards and methods include ISO 14644-1 (cleanroom classification), ISO 14644-3 (test methods), EN 1822 (HEPA and ULPA filters), IEST-RP-CC002 (unidirectional flow clean-air devices), ISO 15190 (medical laboratories, safety requirements) and IEC 61010-1. Certification candidates for this model are CE and ISO 9001 manufacturing; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Place the cabinet in the pre-PCR area for reaction set-up and keep a separate area for post-PCR work, using dedicated pipettes and consumables. Clean the work surface with a validated decontaminant before and after each session, and run the UV lamp for the set period, ensuring the sash interlock prevents exposure. Replace the UV lamp at the end of its rated life, since output falls before total failure, and check lamps with a meter if available. For HEPA models, verify filter integrity and face velocity at installation and at least annually, and change prefilters as specified. Do not use the cabinet for hazardous aerosols or chemical vapour, and keep airflow free of draughts by siting it away from doors.

How do I select the right Benchtop PCR Cabinet?

Choose a benchtop cabinet for single-operator work in a small laboratory where a full clean bench is not needed. Confirm internal size fits the pipette and rack used. RFQ: width, height, dead-air or HEPA, UV timer, lighting and power.

How does it compare with other PCR Cabinets variants?

Choose a HEPA laminar flow PCR cabinet when the work needs a clean air zone over the samples, for example when preparing reactions from low-copy templates. Choose a dead-air or still-air workstation when the priority is physical isolation and UV decontamination rather than particle removal. Confirm that the UV lamp, timer and sash interlock suit the decontamination procedure, and that the internal height and footprint fit pipettes, racks and a small centrifuge. Decide whether the cabinet recirculates or is ducted, and whether a white light or blue light option is needed. For regulated diagnostics, check that the cabinet supports the workflow and cleaning validation, and verify filter performance where HEPA is fitted. Good laboratory layout with separate pre- and post-PCR zones matters as much as the cabinet itself.
