New automatic cloud and pour point analyser
Koehler Instrument Company, Inc. is pleased to announce the launch of the new K77000 / K77001 Automatic Cloud and Pour Point Analyser. This cutting- edge instrument is ideal for measuring cloud point by the Optical Detection Stepped Cooling Method ASTM D5771 and pour point by the Automatic Tilt Method ASTM D5950. The cloud point is an index of the lowest temperature of a petroleum product or biodiesel fuels utility for certain applications. Wax crystals of sufficient quantity can plug filters used in some fuel systems. The pour point of a petroleum product is an index of the lowest temperature of its utility for certain applications. Flow characteristics, such as pour point, can be critical for the correct operation of lubricating oil systems, fuel systems, and petroleum blending and pipeline operations.
This covers a wide temperature range and can reach temperatures down to -105°C. After preliminary heating, the test specimen is inserted into the analyser. Once the program is started, the specimen is cooled in accordance with the cooling profile listed in the ASTM method and examined at either 1°C or 3°C intervals. The lowest temperature whereby motion of the specimen is detected, by automatic equipment, is conveniently displayed as the pour point.
Key features include a wireless cloud or pour point head, integrated cooling system, automatic calibration by means of 10 point RTD Calibration, sample calibration and jacket calibration. Also included is an industrial touch screen user interface with a 10.4-inch colour touch screen built-in. This state-of-the-art instrument also comes with USB and network connections including four USB interfaces and an internet (Ethernet) line.
The integrated software includes the preprogrammed standard test methods. Alternately, user-define test programs can also be created. In addition, there is a clear graph of temperature vs. time for sample and bath temperatures. Results can easily be searched for, viewed on screen, printed and sent via LIMS.

50646pr@reply-direct.com Compact gas diluter with a smart software
On-site customised gas standard preparation has never been easier than with Zephyr – a compact version of well-known GasMix™ gas mixers/diluters from AlyTech. This compact device is a smart companion in quality assurance for all gas analysers, GC or gas detectors helping you significantly reduce your stock of gas standard cylinders and related cost.
Compliant with the ISO6145-7 international standard method “Gas analysis -- Preparation of calibration gas mixtures using dynamic volumetric methods” the Zephyr is a very cost efficient solution for creating a multi-point calibration curve from a concentrated gas standard and a diluent. This diluter is compatible with aggressive gases and active compounds like sulphurs gases, ammonia and VOCs.
With its touch screen and intuitive interface the device is very simple in operation. The unique Smart Sequence building feature helps the operator to make multi-point calibration curves easily: Just choose the number of points, starting and ending concentration values, and the software calculates the respective flow rates. The sequence is stored in the memory and recalled at any time.
When it is used for the calibration of an analyser, the accuracy of generated gas is very important. The uncertainty of the final gas concentration is calculated automatically taking into account the actual used flow and the certified uncertainty of the parent gas. With flow accuracy ±0.5% of the set point all over the scale the Zephyr adds very little dilution error while offering very wide dilution ratio up to 10000. With its small foot print, imbedded smart software and optional internal battery (up to 8h autonomy) it can be installed where you need it, in the lab, in the field or in a mobile lab.

LECO’s TGA801 checks all the boxes Superior analytical performance? Check.
Unparalleled versatility? Check. Innovative system design? Check.
LECO’s TGA801 checks all the boxes for a state- of-the-art automated macro thermogravimetric analyzer. An integrated, thermally isolated 0.0001g low drift balance ensures stable and precise mass measurements throughout the analysis cycle, while the furnace capabilities allow for automated, multi-sample analysis batches of up to 19 samples. LECO’s rugged, high-performance ceramics enable operation temperature up to 1000°C. An external ventilation system reliably removes furnace exhaust while eliminating possible balance vibration interference. In addition to LECO’s innovative Cornerstone®
brand software,
every TGA801 comes with the knowledge and reassurance that LECO’s global and regional service network stands behind it. Our Technical Service Laboratory has experienced technical application chemists to assist in method development and application-related requests.

Do more with LECO’s SC832 carbon and sulfur determinator in your laboratory. LECO’s high- efficiency furnace system design dramatically lowers operating costs. The horizontal high temperature (up to 1550 °C with optional HT model) concentric ceramic furnace tube with ceramic lance channels oxygen directly onto the sample to ensure rapid analysis times, complete combustion, and recovery. An improved solid-state IR cell design simplifies set-up and calibration, while an optional autoloader with 100-sample capacity simplifies the operator workflow and increases productivity. A boom-mounted touch-screen option reduces bench space requirements while allowing for an ergonomic workspace. An intuitive design puts the dual reagent tubes and rotameters on the front side of the instrument, behind a hinged cabinet door. This results in preventative maintenance that becomes fast and simple, ensuring a robust and reliable instrument with superior uptime.
