Filtration Products
Chromatography Direct supplies a comprehensive range of Filtration Products designed to improve sample preparation, protect analytical instruments, and streamline day-to-day lab workflows. For ChemUK 2026, we are showcasing practical filtration solutions that help laboratories reduce particulates, minimise contamination risk, and achieve more consistent results across routine testing and high-sensitivity analysis. Our range includes syringe filters in a choice of membrane types and pore sizes to suit aqueous and solvent-based samples, helping extend column life and improve HPLC/GC/LC-MS uptime. For faster, cleaner sample prep with fewer handling steps, our syringeless filter vials combine filtration and collection in one simple format, ideal for high-throughput environments. We also supply plastic syringes to support safe, reliable manual filtration and sample transfer, plus filter paper for general laboratory filtration tasks in QC, production support, and R&D. For purification and downstream processing, we offer FPLC columns suitable for a range of biomolecule separation and clean-up workflows. For plate-based screening and parallel processing, our filter plates enable efficient filtration across multiple samples at once, supporting higher throughput with consistent performance. Our bottle top filters provide convenient filtration into laboratory bottles, reducing transfer steps while supporting sterile or particle removal applications (such as media, buffers, reagents, and environmental samples). To support safe venting and contamination control, our vent filters help protect systems and maintain cleanliness in storage and processing workflows. Whether you are optimising sample preparation, scaling throughput, or improving contamination control, Chromatography Direct can help you select the right filtration format, membrane, and configuration for your application.

Flame Arresters
A Flame Arrester is designed to allow the safe flow of gases and liquids while preventing flame transmission. Flame Arresters are composed of spirally wound metal bands with precisely reproducible flame-quenching gaps. These gaps are adjusted to the ignition transmission capability of explosive vapors. The FLAMEFILTER® is made of wound metal strips and forms an effective band arrester. This flame-quenching principle is applied in PROTEGO® end-of-line flame arresters and in-line flame arresters. When a mixture ignites in a gap, the flame spreads towards the unburned mixture. The volume expansion of the burned mixture pre-compresses the unburned mixture and accelerates the flame propagation. Heat dissipation to the large surface of the gap lowers the temperature below the ignition temperature, thus extinguishing the flame. The gap width and gap length determine the extinguishing effectiveness of the Flame Arrester. A narrower and longer gap extinguishes the flame more effectively, while a wider and shorter gap reduces the pressure loss. Experiments can determine the optimum solution between the two conditions.

Flash Chromatography
Chromatography Direct supplies a focused range of Flash Chromatography products to support fast, reliable purification in synthesis and R&D laboratories. For ChemUK 2026, we are highlighting practical consumables that help chemists improve separation performance, speed up purification, and achieve consistent results when isolating reaction products, intermediates, and impurities. Our range includes flash cartridges designed for efficient, reproducible separations across a wide variety of compound types and solvent systems. Choosing the right cartridge format and media can improve resolution, reduce run times, and increase recovery, helping you maintain throughput without sacrificing quality. To support rapid method selection and monitoring, we also supply TLC plates for quick assessment of reaction progress and solvent system optimisation. TLC remains a simple but powerful tool for screening conditions, tracking fractions, and confirming compound behaviour before and after flash runs. We also provide a selection of flash chromatography accessories to help keep workflows smooth and dependable, supporting set-up, operation, and fraction handling while reducing avoidable downtime. In addition, our silica products support both flash chromatography and wider purification needs, where the right silica choice can be critical for selectivity, loading capacity, and separation quality. Visit our ChemUK 2026 profile to explore our flash cartridges, TLC plates, silica, and accessories, and speak with the Chromatography Direct team about the best options for your purification workflow.

Flash Point Testers
Innovation in flash point testing. At which temperatures will your sample burn, ignite, or cause fire? How are your flammable liquids composed, and what are their properties? Volatility is directly related to a substance‘s flash point temperature (flammability). Anton Paar’s flash point testing equipment safely and easily determines the values you require for the processing, storage, transportation, and classification of dangerous liquids.

Flo-Tel - Non-invasive burst sensor
Flo-Tel is a practical, reusable burst detection solution for indicating when a rupture disc has activated. Operating on a simple reed switch and magnet technology, the Flo-Tel burst sensor fits into a holder with a magnet on the rupture disc. When the rupture disc bursts, the magnet arcs away from the sensor, giving an open circuit signal. Flo-Tel is non-invasive to the process and is therefore unaffected by downstream pressure fluctuations or corrosion. This feature also eliminates leak paths and the risk of false alarms associated with traditional membrane-type burst detection systems. After rupturing, the disc is the only element that needs replacing, which eliminates the need for expensive re-wiring costs and maintenance planning. Available with a 2m, 5m or 10m cable, Flo-Tel is Suitable for process temperatures up to 300°C and offers a fail-safe detection system. Flo-Tel is ATEX approved to II 1G Ex ia IIC Ga and II 1D Ex ia IIIC Da IP66. It carries the EC-Type Examination Certificate ITS03 ATEX 21698X. Please note that it must be connected to an intrinsically safe supply.
