The B5200 is the Benchmark SureAir PCR Workstation — a dedicated benchtop PCR workstation with laminar-flow workspace and UV-C decontamination capability for PCR contamination control workflows. Sold at $2,479 as a capital workstation, the SureAir provides isolated, decontamination-controlled workspace for PCR setup, particularly the pre-amplification step where DNA template handling must be rigorously isolated from post-amplification PCR product (whose aerosolized fragments can cause carryover contamination that destroys downstream PCR specificity). Ships only by freight — significant size / weight equipment requiring freight delivery (vs the standard parcel shipping of smaller bench instruments).
Author confidence note (MEDIUM): No specific B5200 brochure in available corpus. Specs sourced from universe label. Confirm exact workstation dimensions, HEPA filter specifications, UV-C wavelength / cycle protocol, laminar flow rate, sash design, electrical service requirements, and EU plug variant availability with Benchmark Scientific technical support at first procurement.

Why a Dedicated PCR Workstation — Carryover Contamination Control
PCR carryover contamination is the dominant source of false-positive PCR results in lab environments. Aerosolized PCR product (microscopic droplets generated during pipetting / tube uncapping after amplification) can contaminate pre-amplification reagents and templates, producing false-positive signals that destroy downstream PCR specificity.
The standard mitigation is physical isolation of pre-amplification work from post-amplification work:
- Pre-amplification space — DNA template handling, master mix prep, reaction setup
- Post-amplification space — thermal cycler, gel running, product analysis
A dedicated PCR workstation like the SureAir provides the pre-amplification isolated workspace with three contamination-control features:
1. Laminar flow — directs filtered air across the workspace (typically away from the operator), preventing aerosol settling onto reagents / templates during setup.
2. UV-C decontamination cycle — between work sessions, UV-C illumination decontaminates workspace surfaces by cross-linking any residual DNA (preventing carryover on workstation surfaces).
3. Physical workspace isolation — the enclosed workstation isolates the workspace from general bench air / aerosol.
Pick the SureAir PCR Workstation (B5200) when:
- Workflow involves PCR setup at any meaningful throughput
- qPCR setup where template-amount sensitivity makes carryover even more impactful
- NGS library prep where multi-cycle amplification compounds carryover effects
- Diagnostic / clinical PCR workflows where false positives have downstream consequences
- Multi-investigator shared PCR facility standardizing on contamination-controlled workspace
- Method-development workflows comparing protocol-specific contamination vulnerability
Skip the dedicated workstation for occasional / low-stakes PCR workflows where carryover risk is acceptable — but document carryover-risk-tolerance decision in protocol records.
PCR Workstation vs UV Clave Decontamination Chamber
The SureAir and the B1450 UV Clave both use UV-C decontamination, but serve different workflows:
| Feature | SureAir PCR Workstation (B5200, this product) | UV Clave UV-C Chamber (B1450 family) |
| Primary workflow | PCR setup workspace with active contamination control | Periodic decontamination of items |
| Workspace | Active workspace for protocol execution | Closed chamber for batch decontamination |
| Laminar flow | Yes | No |
| UV-C decontamination | Yes (cycle between work sessions) | Yes (primary decontamination cycle) |
| HEPA filtration | Yes (laminar flow source) | No |
| List price | $2,479 | $627 |
| Best for | Daily PCR setup contamination control | Periodic surface decontamination of heat-sensitive items |
Pick the SureAir for daily-use PCR setup workspace; pick the UV Clave for periodic between-use surface decontamination of heat-sensitive items.
Application Profile
PCR setup contamination control — daily-use pre-amplification workspace for routine PCR / qPCR / NGS workflows.
qPCR setup workflows — contamination control matters even more for qPCR where template-amount sensitivity amplifies the impact of carryover.
NGS library prep — multi-cycle library-prep amplification compounds carryover risk.
Diagnostic / clinical PCR workflows — clinical PCR labs requiring rigorous contamination control.
Multi-investigator shared PCR facility — facility-scale PCR contamination control standardization.
Pharmaceutical / biotech research PCR workflows — high-stakes PCR procurement.
Educational laboratory teaching — graduate / postdoc programs introducing PCR contamination-control fundamentals.
Method-development workflows — protocol-development requiring contamination-controlled setup environment for comparison-baseline integrity.
Frequently Asked Questions
Why does the B5200 ship only by freight? It is significant size/weight equipment that is not parcel-shippable — confirm receiving capability (loading dock, freight elevator, lift-gate truck) at the destination.
What contamination-control features does the SureAir provide? Three: laminar flow that directs filtered air across the workspace, a UV-C decontamination cycle for workspace surfaces between sessions, and physical isolation of the enclosed workspace from general bench air.
How does the B5200 differ from the B1450 UV Clave? The SureAir is an active PCR-setup workspace with laminar flow and HEPA filtration ($2,479). The UV Clave is a closed chamber for periodic surface decontamination of items ($627), with no workspace or laminar flow.
Is there a safety hazard with the B5200? Yes. The UV-C decontamination cycle is an eye/skin exposure hazard — run it only with the sash closed / interlock engaged and the workspace unoccupied, and train all operators in UV-C safety.
Ordering & Configuration
Confirm freight delivery logistics. The B5200 ships only by freight — confirm receiving capability at destination (loading dock, freight elevator access, lift-gate truck if needed). Plan freight delivery scheduling carefully.
Confirm bench / floor space. Significant equipment footprint — confirm available facility space at order.
Confirm voltage and EU plug variant availability. B5200 = 115 V US per universe label. No -E variant currently shown in universe — confirm EU procurement with Benchmark Scientific tech support if international shipment is required.
Plan UV-C lamp replacement cycle. UV-C lamps degrade over operating hours; plan periodic lamp replacement as part of long-term maintenance.
Confirm interlock and operator-safety protocols. Like the UV Clave, UV-C exposure is immediately hazardous to eyes and skin. Train all operators in UV-C safety; verify interlock function before each cycle.
Plan PCR workflow integration. Pair with separate post-amplification workstation / area to support physical pre/post-amplification isolation.
Confirm at quote: voltage / plug type, freight delivery logistics, facility space, intended PCR workflow contamination-control scope, UV-C operator safety training, PCR workflow integration plan, lead time.
Warranty: Per Benchmark Scientific standard capital-equipment terms — confirm at quote.
Safety note: the SureAir PCR Workstation includes UV-C decontamination cycles with eye / skin exposure hazard — operate the UV-C cycle only with sash closed / interlock engaged; train all operators in UV-C safety. Decontamination cycle should run only when workspace is unoccupied.
