    What you get

    Four answers. One clear plan.

    You need to know what your workforce is exposed to, whether your controls are effective, what actions matter most, and how to demonstrate control confidently.

    That is exactly what we deliver.

    01

    02

    Coliform & E. coli

    Presumptive coliform and E. coli enumeration where the brief requires.

    03

    Per-environment benchmarks

    Results contextualised against cleanroom, food, healthcare or water-system action levels.

    Why clients call

    If any of this sounds familiar, you're in the right place.

    1. 01

      An auditor is asking

      HSE, your insurer or a client wants evidence — not assurances

      We provide measured TVC analysis data and a clear technical report that resolves the issue quickly.

    2. 02

      Your team is worried

      Operatives are reporting concerns or symptoms

      We attend site, quantify workforce exposure and provide clear evidence of current risk levels.

    3. 03

      You suspect a problem

      You know there's a risk and you want measured data before it becomes a crisis

      We quantify exposure, assess it against current limits and provide a prioritised corrective action plan.

    What we answer for you

    Three questions, settled.

    Where your people are exposed
    We map the tasks, areas and shifts where TVC analysis matters, then sample what your team actually breathes — not a generic site average.
    Whether your controls are working
    An independent review of your LEV, ventilation, PPE and work practices — what is effective and what requires improvement.
    What you need to fix first
    A prioritised, costed action list — the smallest set of changes that gets you compliant and measurably safer.

    How we work with you

    From your first call to your action plan.

    1. 1

      We listen first — your site, your concerns, your deadline.

    2. 2

      We walk the workplace with your team to see exposure as it actually happens.

    3. 3

      We sample on the people most at risk, using validated occupational hygiene methods for TVC analysis.

    4. 4

      We assess your existing controls honestly — what's working, what isn't.

    5. 5

      You receive a clear technical report suitable for operational, compliance and regulatory readers.

    6. 6

      We hand you a prioritised action plan you can budget, schedule and defend.

    Background

    TVC analysis, in detail.

    What TVC measures

    Total viable count is a measure of the cultivable aerobic bacterial bioburden in a sample. It is the standard environmental microbiology baseline for cleanrooms, food production, healthcare and water systems. It does not identify species — it quantifies the bioburden against an action level.

    Sample types and methodology

    Air sampling by impaction (Andersen, MAS-100), surface sampling by contact plate or swab, and water sampling by membrane filtration. Plates are incubated at 22 °C and 37 °C for the standard 48-hour period; coliform / E. coli enumeration is added where the brief requires.

    Action levels

    Action levels depend on the environment — Grade A/B/C/D for cleanrooms (EU GMP), HACCP-derived for food, BSI 8551 for water etc. Our reports always state the framework being benchmarked against.

    Quick answers to the questions we hear most from operations, HSE and procurement teams.

    What sample types do you accept?
    Air, surface (contact plate / swab) and water samples.
    Do you identify species?
    TVC is enumeration only. Species ID is available as a separate service when required.

    Do you support cleanroom monitoring?
    Yes — including EU GMP Grade A–D environmental monitoring programmes.

    Yes — added on request for relevant samples.
    Where are you based?
    UK-based laboratory with national post-in service.
