Products

• BELCAT II: Catalyst Analyser: Chemisorption and temperature programmed analyser for catalyst characterisation, covering temperature programmed desorption, reduction and oxidation as well as pulse chemisorption. These measurements give active metal surface area and dispersion, which is what determines catalyst activity.
• BELMASS II: Quadrupole Mass Spectrometer: Quadrupole mass spectrometer that couples to the BELCAT analyser to identify the gases evolved during a temperature programmed experiment. Without it a thermal conductivity trace shows that something desorbed; with it, what desorbed can be named.
• BELMETAL 3: Metal Dispersion Rate Analyser: Analyser dedicated to measuring metal dispersion in supported catalysts, that is the fraction of metal atoms exposed at the surface and therefore available to react. It is a focused instrument for catalyst development where dispersion is the number being optimised.
• DIMENSIONS: Measurement and Evaluation Software: Control and evaluation software for Microtrac particle size and shape analysers, handling measurement setup, result calculation and reporting. It presents laser diffraction and image analysis data in one environment, which matters on the SYNC where both are acquired together.
• BELCONTROL: Operation Software for BELSORP Series: Common operating software for the BELSORP adsorption analysers, running measurement sequences and calculating surface area, pore size distribution and related quantities from the isotherm. One interface covers the whole BELSORP range.
• CAMSIZER 3D: Particle Size and Shape Analyser: Dynamic image analyser that photographs particles in free fall with two cameras and derives size, shape, volume, density, transparency and count from the images. Working to ISO 13322-2, it covers a recommended range from 20 µm to 30 mm with no hardware change, which suits granules, tablets, aggregates and abrasives.
• CAMSIZER X2+: Particle Size and Shape Analyser: Dynamic image analyser for fine powders, covering 0.9 µm to 8 mm with a digital resolution of 0.9 µm per pixel. Three dispersion options are built in, air pressure, gravity and wet, so cohesive powders and suspensions can both be measured on the same instrument. Shape parameters follow ISO 9276-6.
• CAMSIZER XL: Particle Size and Shape Analyser: Large particle image analyser covering 160 µm to 135 mm, so it reaches into the size range normally handled by sieving. That makes it directly relevant to aggregate, fertiliser and mineral grading, where it produces size and shape data from a sample of a few kilogrammes in minutes.
• CAMSIZER S1: Particle Size and Shape Analyser: Benchtop dynamic image analyser in the CAMSIZER family, aimed at laboratories that need image based size and shape data in a smaller footprint than the X2+ or 3D. It works on the same free fall imaging principle to ISO 13322-2.
• CAMSIZER ONLINE: In-Process Particle Size and Shape Analyser: Process version of the CAMSIZER, built into a stainless steel housing so it can be mounted in a production loop and measure size and shape continuously rather than on grab samples. It covers 30 µm to 30 mm for dry free flowing powders, granulates and bulk material.
• CAMSIZER ONLINE XL: In-Process Particle Size and Shape Analyser: The large size version of the process CAMSIZER, covering 160 µm to 135 mm for coarse bulk material moving on a production line. It uses the same imaging principle and stainless steel construction as the standard ONLINE unit in a larger frame.
• S3500: Particle Size Analyser: Laser diffraction particle size analyser using three precisely positioned red laser diodes rather than a single beam, which extends the angular coverage without moving optics. It measures from 0.02 µm to 2.8 mm in ten to thirty seconds and reports volume, number and area distributions.
• BLUEWAVE: Particle Size Analyser: Laser diffraction analyser that adds two blue 405 nm lasers to the red source, because the shorter wavelength improves resolution at the fine end. It measures from 0.01 µm to 2.8 mm and applies Mie theory for spherical particles with a modified Mie calculation for non-spherical ones.
• SYNC: Combined Laser Diffraction and Dynamic Image Analyser: Analyser that runs laser diffraction and dynamic image analysis on the same sample stream at the same time, so size distribution and shape data come from one measurement rather than two instruments. It covers 0.01 to 4000 µm and works to ISO 13320 and ISO 13322-2 together.
• AEROTRAC II: Spray Particle and Droplet Size Analyser: Laser diffraction analyser configured for airborne particles and droplets, measuring sprays, mists and atomised liquids in flight. Three interchangeable lenses cover 0.5 µm to 2000 µm, and spray measurements can be as short as 0.02 milliseconds to capture a single pulse.
• NANOTRAC FLEX: Nanoparticle Size Analyser: Dynamic light scattering analyser using an external probe rather than a cuvette, so measurements can be taken in situ in a reaction vessel or process line. It covers 0.3 nm to 10 µm and works at sample concentrations up to 40 per cent, which removes the dilution step that normally distorts a DLS result.
• NANOTRAC WAVE II: Nanoparticle Size and Zeta Potential Analyser: Dynamic light scattering analyser that measures particle size, zeta potential, concentration and molecular weight in one benchtop instrument. Combining size and charge in a single measurement is useful for colloid and formulation work, where stability depends on both together.
• STABINO ZETA: Zeta Potential Analyser: Zeta potential analyser based on the streaming potential principle, a mechanical measurement rather than an optical one, so it works on concentrated and opaque dispersions where electrophoretic light scattering fails. It performs fast titrations and measures pH and conductivity alongside charge.
• TURBISCAN LAB: Stability Analyser: Stability analyser that scans a sample vial with an 880 nm beam and records transmitted and backscattered light along its whole height, so sedimentation, creaming, flocculation and coalescence are detected before they are visible. The sample is measured undiluted and undisturbed in its native state.
• TURBISCAN TOWER: Multi-Sample Stability Analyser: Multi-sample version of the Turbiscan stability analyser, holding several vials in a temperature controlled tower so a formulation series can be aged and scanned in parallel. It uses the same static multiple light scattering measurement as the LAB model.
• TURBISCAN TRILAB: Multi-Sample Stability Analyser: Stability analyser combining multi-sample scanning with additional characterisation channels, so more than one property of a dispersion can be followed over the same ageing period. It is aimed at formulation laboratories comparing several candidate recipes.
• TURBISCAN AGS: High-Throughput Stability Analyser: High throughput stability analyser with an ageing station, so samples are held at a controlled temperature and scanned automatically over days or weeks without an operator. That turns shelf life prediction into an unattended experiment.
• TURBISCAN DNS: Dispersibility and Stability Analyser: Analyser that measures how readily a powder disperses into a liquid as well as how stable the resulting dispersion is, by scanning the vessel while dispersion takes place. Dispersibility and stability are separate properties, and this instrument records both in the same run.
• BELSORP MINI X: BET Specific Surface Area and Pore Size Analyser: Volumetric gas adsorption analyser for BET specific surface area and pore size distribution, the routine workhorse of the BELSORP range. It measures nitrogen or other gas uptake at cryogenic temperature and derives surface area and pore structure from the isotherm.
• BELSORP MAX X: High-Precision Gas and Vapour Adsorption Analyser: High precision adsorption analyser handling vapours as well as permanent gases, so water, organic solvent and other vapour isotherms can be measured alongside nitrogen. It is the research grade instrument in the BELSORP line, used for micropore analysis and adsorbent development.
• BELSORP MAX G: High-Precision Gas Adsorption Analyser: High precision gas adsorption analyser for surface area and pore size distribution, configured for permanent gases rather than vapours. It sits between the MINI X and the MAX X, giving research grade precision for laboratories that do not need vapour capability.
• BELSORP MR1: BET Surface Area Analyser: Single point and multipoint BET surface area analyser aimed at routine quality control rather than full isotherm research. Where a laboratory only needs a specific surface area figure per batch, it gives that result faster than a full volumetric instrument.
• BELCRYO X: High-Precision Cryogenic Unit: Cryogenic temperature control unit for BELSORP adsorption analysers, replacing the liquid nitrogen dewar with a closed cycle cooler. It removes the need to refill coolant during long isotherm runs and holds the adsorption temperature more steadily than an evaporating bath.
• BELSORP HP: High Pressure Gas Adsorption Instrument: High pressure adsorption instrument for measuring gas uptake well above atmospheric pressure. That is the regime that matters for hydrogen and methane storage, for carbon dioxide capture and for screening adsorbents used in gas separation. Isotherms are measured volumetrically, as on the other BELSORP instruments, but with a pressure range that ordinary surface area analysers do not reach.
• BELPORE Series: Mercury Porosimeter: Mercury intrusion porosimeter that forces mercury into a porous solid under increasing pressure to derive pore size distribution and total pore volume. It covers the macropore and mesopore range that gas adsorption cannot reach, and is used on ceramics, catalysts, cements and rock.
• BELPYCNO: Density Analyser: Gas pycnometer that determines true density of powders and porous solids by measuring the volume of gas that the sample displaces, so open pores are excluded from the volume. Helium is normally used because its small molecule penetrates fine pore structures.
• BELPYCNO L: Gas Pycnometer: Larger chamber version of the BELPYCNO gas pycnometer, for samples too bulky for the standard cell. It uses the same gas displacement principle to give true density excluding open porosity.
• BELPREP VAC II: Vacuum Degasser: Vacuum degassing station that removes adsorbed moisture and gases from samples before an adsorption measurement. Incomplete degassing is the commonest source of error in BET surface area work, because residual water occupies the sites the measurement is meant to count.
• BELPREP VAC III: Vacuum Degasser: The current generation vacuum degasser in the BELPREP line, preparing samples for gas adsorption analysis by heating them under vacuum until adsorbed species are removed. It is used ahead of BET surface area and pore size measurements.
