From Crime Scene to Crime Lab: How BenchVent Equipment Supports Forensic Investigations

From Crime Scene to Crime Lab: How BenchVent Supports Forensic Investigations
In forensic science, the journey of evidence—from the crime scene to the laboratory—is critical. Each step must be precise, safe, and contamination-free to ensure reliable results.
BenchVent plays a vital role in this process by offering portable forensic tools and lab-grade filtration systems designed to protect both personnel and evidence.
In this blog, we’ll walk through the full forensic workflow and explain how BenchVent equipment improves safety, accuracy, and efficiency at every stage.
Step 1: Collecting Evidence at the Crime Scene
At the scene, investigators must collect evidence without compromising its integrity. BenchVent’s portable, filtered equipment makes this task safer and more reliable.
Key Crime Scene Tools
Equipment | Purpose |
---|---|
Ductless Fume Hoods / Forensic Hoods | Capture and filter chemical fumes during presumptive tests |
Evidence Drying Cabinets | Safely dry biological samples such as blood or DNA |
Glove Boxes | Provide a sealed, controlled environment for sensitive materials |
HEPA / Carbon Filters | Remove harmful particles, fumes, and odours |
Benefits:
-
First and foremost, they prevent cross-contamination
-
Additionally, they protect investigators from hazardous materials
-
Most importantly, they ensure safe, clean evidence handling on-site
Step 2: Packaging and Chain of Custody
After collection, evidence must be packaged and transported with care. This ensures it remains valid for both scientific analysis and legal proceedings.
What Happens Next:
-
Each item is labeled, sealed, and logged
-
Moreover, all actions are documented to maintain the chain of custody
-
Items are then transported securely to prevent tampering or degradation
-
Furthermore, personnel are protected from toxic powders and biological hazards
With BenchVent containment systems, teams gain added protection and peace of mind during this critical phase.
Step 3: Crime Lab Analysis
Once the evidence reaches the lab, it undergoes specialized testing. BenchVent lab equipment helps maintain a clean, sterile environment—crucial for accurate results.
Forensic Lab Equipment
Category | Equipment | Purpose |
---|---|---|
DNA Amplification | PCR Thermocyclers | Replicate DNA samples |
DNA Separation | Gel Electrophoresis Systems | Separate DNA fragments |
DNA Profiling | Capillary Electrophoresis Systems | Match DNA for use in databases (e.g., CODIS) |
Fingerprint Analysis | Downflow Workstations | Provide clean, filtered air |
Sample Processing | PCR Cabinets, Biosafety Cabinets, Purair Advanced | Maintain sterile environments |
Not only do these tools improve lab safety, but they also reduce contamination risks significantly.
Why Choose BenchVent for Forensic Work?

Forensic Science Regulator’s Code of Practice: Ensuring Quality and Accountability
The Forensic Science Regulator’s Code of Practice sets the official standards for forensic science activities across England and Wales. It provides clear guidance on essential processes such as primary and peer reviews, requiring forensic units to establish and document their policies and procedures for administrative checks on case files and reports.
Importantly, the code also requires that any disagreements or discrepancies identified during reviews are properly recorded and resolved. This ensures transparency, accuracy, and accountability throughout the forensic evaluation process.
These regulations emphasize the vital role of scientific integrity in forensic investigations—especially regarding the use of specialized machines, air filtration units, and laboratory tools. By aligning with these standards, forensic labs not only uphold the law but also reinforce public trust in the justice system.
