Products
Prepared culture media (pre-poured plates and contact plates)
Range of pre-poured agar plates and contact plates in multiple sizes and fill volumes for environmental monitoring and sterility testing; supplied with batch QC and Certificates of Analysis. Presentation options include standard and deep-fill plates for high-airflow applications and versions intended for ambient storage.
Gamma-irradiated media and barrier packs
Sterile, gamma-irradiated media products and multi-layer barrier pack solutions designed to reduce contamination risk and extend shelf life for use in sterile production and validation activities.
Bagged broth products and glass ampoules
Bagged broth media supplied in multiple volumes (100 mL, 1 L, 2 L, 4 L, 10 L) manufactured from EVA or multi-layer films with integrated ports (luer, MPC) and septa for media-fill and operator/process simulations; Type 1 glass ampoules (10 mL) are supplied for small-volume validation use. Irradiated bagged variants and overwrapped sterile presentation available.
Handheld, isolator and compressed-air microbial samplers
Range of viable air samplers for handheld use, isolator cabinet installation and non-powered compressed-air sampling using impaction/impinger compatibility with standard contact plates or Petri dishes.
Portable continuous real-time bioaerosol monitor
Portable continuous airborne particle counter combining particle sizing and intrinsic fluorescence detection to provide immediate alerts, trend analysis and diagnostic data for contamination events without consumable plates.
Sampler accessories and consumables
Accessories such as settle plate stands, contact plate carriers, disposable sampler heads, tripod/stand mounts and Rodac-weight surface samplers to support EM programs and enable consistent sampling technique.
