Waters Quattro Micro GC Mass Spectrometer Module Lab

The compact one-channel gas chromatograph of the brand Interscience type Focus GC is designed to det (more)ermine the composition of a mixture both qualitatively and quantitatively. This gas chromatograph can be used in toxicology, doping research, forensics, in the petrochemical industry, in food safety monitoring and in the pharmaceutical industry. Equipped with a FID detector and a Thermo TriPlus autosampler with reagent heater.

Seaward Stomacher Model: 80 Biomaster Lab System Lab This item was removed from a university where i (more)t was surplus to requirement. It is in very good cosmetic condition and powered on, we are unable to test it further at our facility.

Reason for return - Investigate faults and re-list accordingly: - We received the item with a cracke (more)d glass piece to the photoionization detector. We replaced it with a piece that was provided. - We piped the system with N2 carrier gas and gas lines carrying product to the inlet of the GC. We turned on the switch to the Photoionization detector, under high sensitivity, and can visibly see it turn on. The source is aligned. The detector is aligned.  - We programmed the event on the software to turn the valve of the 10-way valve accordingly to enable the carrier gas to bring the product through the GC. - We introduced acetone via the sample loop (inlet gas) - we saw no peaks. We introduced acetone via injection - we saw no peaks.  - I leaked checked the piping including within the detector - no issues. I checked the point of outlets to make sure flow is continuous too - no issues. - The mechanism of the valve turning - it made a cranky sound, and I am not convinced it is turning the valve.  - There may be two issues. I had figured it was the valve so I tried injecting acetone directly into the line, but we could not see any peak of acetone. (Issues with the detector?) I am not sure if the valve's squeaking/cranky sound implies it is turning but there might be an issue here too. This SRI 8610C GC Gas Chromatograph System was removed from a university lab where it was surplus to requirements. The unit powers up but we were unable to test it further at our facility. The lab did confirm however, that is in good working order. It is in very good cosmetic condition with only very minor marks from use.

The HRP 5Y.KO series of mass comparators enables calibrating mass standards and weights in accordanc (more)e with OIML Recommendation (R-111) for class F2 and lower classes. Comparators are used to ensure consistency in mass measurements as well as to verify weights according to legal metrology requirements. RADWAG mass comparators have been recognized by calibration laboratories in many countries. The HRP 5Y.KO mass comparators consist of two elements: a professional weighing platform (modern design of an electromagnetic mechanism in a hermetic steel casing) and 5Y terminal. The weighing platform is made of steel and features marks facilitating centric loading of mass standards. The comparator can be equipped with a self-centring weighing pan (extra charge), which significantly minimises the influence of eccentricity during measurements. The self-centring weighing pan eliminates the error of placing the weight "out of pan centre". This solution also enables calibrating weights of different shapes and dimensions without the need to set the positioners for central loading of the mass standard each time. The comparator has a user-friendly menu. Data security and work results archiving are ensured by RADWAG terminal software.

Pallet scales is stable and proved 4 load cell construction designed for weighing pallets. The load  (more)to be weighed can be placed on the platform by a standard fork-lift truck. The pallet scales C315.4P series is manufactured in mild steel powder coated version. The H315/4P series features wheels and handles for easy transporting the scales to its place of use. The scales comes standard with an indicator PUE C315 series featuring backlit LCD display and function buttons. The indicator is installed on a long cable. The scale is powered from mains 230V AC, RS 232 interface comes standard. Scales is available in dual range version on surcharge.

Heidolph 036300450 Overhead Stirrer Impeller, AR 19 Anchor-Type Particularly in applications with ve (more)ry viscous media, it is important to have a stirring tool in use that enables the mixing process up to the edges of the vessel. This explains the shape of the anchor-type impeller and the width of the stirring blade of 60 mm. The AR 19 anchor-type impeller is ideal for vessels with the following characteristics: ideal vessel diameter: 67 mm, ideal ground clearance: 2 mm, ideal filling level: 67 mm, and ideal volume: 200 ml. The anchor-type impeller consists of a PTFE blade and a PTFE-coated stainless-steel shaft. The stainless-steel core ensures the stability of the stirrer shaft and the secure attachment in the overhead stirrer. The diameter in the clamping area is 6.5 mm; the stirrer shaft with the thick-walled PTFE coating has a diameter of 8 mm. Due to its anti-adhesive property (non-stick coating), the anchor-type impeller is easy to clean and can be used up to a maximum application temperature of 250°C. INCLUDED: The Heidolph 036300450 Overhead Stirrer Impeller, AR 19 Anchor-Type includes: - Manufacturer's Documentation - 3 Year Manufacturer's Warranty
