12 Circular Dichroism beyond single-point checks: First accredited ISO 17025 CRMs deliver spectrum-wide confidence


Circular Dichroism (CD) spectroscopy is central to structural biology and chiral analysis. However, in 2025, many laboratories still rely on camphor-10-sulfonic acid (CSA) or ammonium camphorsulfonate (ACS) for instrument verification. These traditional methods require fresh preparation, are prone to hygroscopic error, and only validate a single peak near 290 nm. The result: The visible range goes untested, and compliance is left exposed.


Starna leads the industry with its Certified Reference Materials (CRMs) for CD. Each set contains permanently flame-sealed quartz cells – Blank, R,R, and S,S enantiomers – spanning both UV and visible regions (190–700 nm and 400–700 nm). Ready-to-use, these references eliminate weighing and waiting, removing preparation variability and ensuring reproducibility across instruments and locations.


Certification extends beyond static tables. Every set features a continuous


Δε(λ) model and U95 uncertainty envelopes, so users can verify performance at any wavelength with confidence. For those who prefer a rapid check, certificates highlight key maxima and minima: anchor points at 210, 237, 274, and 545 nm for UV, and 446, 479, 545, and 605 nm for VIS. Spot-checking instrument performance becomes straightforward, with no need for complex calculations. Certificates are valid for two years, offering lasting assurance between renewals.


As the first and only producer with an accredited (UKAS) scope for CD CRMs, Starna combines ISO 17034 production and ISO/ IEC 17025 calibration for unmatched traceability and compliance. This achievement ensures every set is certified with globally recognised traceability for audit-ready documentation and spectrum-wide reliability.


For regulated environments, the advantages are clear: objective acceptance criteria, reduced operational risk, and data integrity you can defend. Say goodbye to stresses that result from last-minute scrambling to prepare unstable CSA solutions, or worrying about gaps in instrument calibration. With Starna UKAS-accredited CD spectroscopy standards, you can demonstrate compliance and reproducibility across the full spectrum.

The Wiggens Strike Series Rotary Evaporators combine exceptional operational performance with ergonomic design, making them perfect for tasks involving separation, concentration, and purification. These versatile evaporators are designed to scale from laboratory use to pilot plant operations, supporting evaporation flasks of up to 100L. Wiggens offers a comprehensive range of models, from standard units to explosion-proof, ATEX-certified versions. For specialised applications, continuous distillation options are also available, ensuring solutions for all separation requirements.


The latest addition to the series, the lab-scale Strike 185, showcases a modern design paired with cutting-edge technology. A large, intuitive touch screen display enables users to monitor all functions effortlessly. Parameters can be adjusted via the touch screen, turning knob, or a combination of both for quick, precise fine-tuning. To improve


efficiency, the integrated temperature controller, vacuum controller, and timer facilitate automated distillation programs, significantly reducing process time while ensuring precise control.


The Strike 185 operates at rotation speeds ranging from 20 to 300 rpm and supports heating temperatures up to 185°C. An independent safety circuit prevents overheating of the bath tank, while real-time monitoring of steam and cooling water temperatures is possible when temperature sensors are connected. The system accommodates evaporating and collection flasks in various volumes, and the heating bath tank can be adjusted horizontally up to 90mm to fit different flask sizes.

Flexible modular furniture for modern labs


Teknomek, the UK’s leading manufacturer of hygienic furniture and equipment, has launched a new range of modular laboratory furniture designed to meet stringent hygiene standards while offering maximum flexibility. Manufactured from mild steel with white powder-coated frames, the collection combines a clean, contemporary aesthetic with durable performance. Every item is made to order, ensuring a tailored solution for each laboratory.


The new furniture range marks a first for Teknomek in its 40-year history, moving beyond its stainless-steel portfolio to offer powder-coated laboratory products. Each piece has been engineered for easy cleaning and accessibility, with open-sided designs that support good air circulation while maintaining structural stability.


The range includes C- and H-frame benches, cupboards, shelving units and island workstations, available in a wide variety of sizes and configurations. Both bench types can be fitted with suspended rolling rails, allowing under-counter cupboards to be added. This design keeps storage raised off the floor, minimising dust build-up and improving access for cleaning. Because cupboards and drawer units slide along the rail, layouts can be quickly reconfigured to meet evolving laboratory needs or shared workstations.


For environments requiring permanent installations, fixed-to-the-wall options are available. However, the majority of benches and cupboards can be repositioned to adapt to changing requirements, with castors available for added mobility.


Durability is further enhanced with Trespa® TopLab®


PLUS worktops, which provide superior resistance to chemicals, scratches and impacts. The non-porous, antibacterial surface is well suited to laboratories, research facilities and healthcare environments with demanding cleaning protocols.


Michelle Locke, Product and Marketing Manager at Teknomek, said: “Whilst our stainless-steel furniture is ideal for cleanrooms, there is increasing demand for white powder-coated solutions in laboratories and changing rooms. Every product in this new range is made to order, from benches and sinks to our marble- top balance desk, with customisation available in sizes, colours and finishes. This ensures customers receive furniture that is perfectly matched to their project.”


To support customers, Teknomek has also appointed a laboratory sales specialist, bringing direct laboratory management experience to help design flexible, hygienic, and cost-effective workspaces.
