Optimised UV lenses for Forensic Investigation R
esolve Optics is a leading developer of UV lenses that provide an optimised solution that enable detectives and crime scene investigators to capture evidence images not possible using traditional cameras.
Operating in the 320-400nm spectral waveband – Reflected Ultraviolet Imaging Systems, or RUVIS scopes are widely used for detecting traces of fingerprints and bodily fluids, including semen, blood, and saliva left undiscovered by initial visual crime scene investigation.
Designed specifically for forensic investigation – Resolve Optics Model 228 is a full featured high performance UV lens. The lens offers an extended magnification range using a novel telescopic focusing mount that provides a large movement in an extremely compact form. The compact design of the lens has allowed it to be readily adapted to perfectly match the handheld concept of almost any RUVIS system.
Delivering unmatched high performance in both the UV
and visible wavebands, the Model 228 lens enables investigators to identify and focus on a target in the visible and then quickly slide the UV filter across to take images in the UV without having to refocus. Because of its wide field of view and high transmission lens coatings - the Model 228 lens is considerably more light-efficient than any other longer focal length lens offering an identical view.

PRECISION AND PROTECTION: TITAN’S 800 SERIES FLOWMETERS POWER PERACETIC ACID DISPENSING SYSTEMS
I
n modern medical, pharmaceutical, and hygiene applications, peracetic acid (PAA) has become one of the most trusted and effective liquid disinfectants available. As a powerful oxidizing agent with broad-spectrum antimicrobial activity, PAA is valued for its ability to rapidly eliminate bacteria, viruses, fungi, and spores - even at relatively low temperatures. Its fast action, short contact times, and environmentally friendly by-products (primarily acetic acid, oxygen, and water) make it a cornerstone of safety and sterilisation protocols across healthcare, food and industrial settings. However, the same characteristics that make PAA so effective also make it demanding to handle. Its potency is only fully realised when the concentration is precisely controlled. Too low a dose can render disinfection or sterilisation ineffective, putting patients, staff, and equipment at risk. Too high a dose, on the other hand, can lead to equipment corrosion, degradation of sensitive materials, and unnecessary chemical exposure. Achieving and maintaining this balance requires accurate, reliable, and chemically resistant flow measurement technology - qualities that define Titan Enterprises’ NSF-Approved 800 Series flowmeters. The Role of PAA in Critical Hygiene Environments
Peracetic acid is used widely because it fills several important roles in medical decontamination workflows:
• High-Level Disinfection of Medical Instruments
PAA is used extensively in automated endoscope reprocessors (AERs) and other washer- disinfectors that handle flexible endoscopes, surgical instruments, and various heat- sensitive medical devices. These systems rely on precision dosing to ensure that PAA is delivered at exactly the right concentration to guarantee high-level disinfection without damaging delicate components. • Surface Disinfection in Clinical Facilities
Many hospitals and laboratories deploy PAA as a diluted spray or mist to disinfect operating rooms, isolation areas, and critical patient-care surfaces. To maintain consistent efficacy, the dilution process must be carefully controlled to avoid under- or over-concentration.
• Low-Temperature Chemical Sterilisation Systems For instruments that cannot undergo steam autoclaving - due to heat sensitivity, Instrumentation January 2026
embedded electronics, or specialised coatings - liquid PAA sterilisation provides a reliable alternative. These systems depend on repeatable flow and dosing control to ensure sterilisation cycles are both safe and effective. • Pharmaceutical, Bioprocessing & Food Processing Applications
Beyond healthcare, PAA is frequently
used in clean-in-place (CIP) and sterilise-in-place (SIP) systems within pharmaceutical manufacturing facilities, biotechnology labs, and food production environments. Its strong oxidising properties make PAA ideal for fruit and vegetable washing, meat and poultry processing, and packaging line sanitation, providing reliable microbial control without leaving chemical residues. Here again, Titan’s NSF-Approved flowmeters provide precise flow monitoring, essential to maintain high hygiene standards and meet stringent regulatory standards.
Engineering Flowmeters for Chemical Resistance and Precision To meet these diverse and demanding application requirements, Titan’s 800 Series flowmeters are built from materials carefully selected for their robustness and compatibility with aggressive chemicals like peracetic acid. Approved under the NSF standard 169 as ‘Special Purpose Food Equipment and Devices’, the meters incorporate PVDF, seal materials and sapphire, each chosen for specific performance advantages: • PVDF (Polyvinylidene Fluoride): Offers excellent resistance to acids and oxidizing agents, making it ideal for long-term contact with PAA.
• A variety of seal options including Viton™, EPDM and Kalrez®, chosen for their specific chemical compatibility.
• Sapphire Bearings: Provide extremely low friction and high wear resistance, ensuring long operating life even under continuous use.
