Gilson Centrifuge Extractors Model:GSF3-HM-806 | Cat.No: |
Gilson Centrifuge Extractors supervac site:zxqc.cn supervac site:hd315.org supervac site:midwest.com.cn are designed for efficient and reliable quantitative determinations of bitumen content in hot-mix asphalt specimens. Models conforming to explosion-proof requirements are available with 1500 or 3000 gram capacities. A standard version with 1500 gram capacity is also offered. All models offer safe, simple operation and long service life. For each model, the precision machined and balanced inner aluminum bowl assembly quickly lifts out of the sealed housing for efficient specimen handling. Rotation speeds up to 3600 rpm are easily set using the speed control knob. The built-in electric brake stops the centrifuge in seconds when extraction is complete. The heavy cast aluminum outer cover latches securely in place and features an integral solvent dispensing cup. Paper filter rings prevent loss of fines during processing. Twenty five filter rings are included. All models are powered by a reliable 1/8hp DC motor equipped with an electrical braking system. Extra centrifuge bowl assemblies may be ordered for faster sample processing. HMA-263 1500g capacity bowls may also be used on HM-807 3000g extractors. Additional filter paper rings are available as noted below. Dimensions for 1500g units are 12x20x22" (305x508x559mm) DxH, for 3000g units, 14x20x22" (356x508x559mm).

Gilsons Binder Ignition System meets applicable ASTM Model:GSF3-HM-378 | Cat.No: |
Gilsons Binder Ignition System meets applicable ASTM supervac site:zxqc.cn supervac site:hd315.org supervac site:midwest.com.cn Gilson's Binder Ignition System meets applicable ASTM and AASHTO standards, offering true economy in a simple, manually operated unit. Process times are comparable to automatic-weighing units, and extensive testing has proven that results equal or exceed the accuracy of automated systems. Standard 1,200-1,800g samples are processed in as little as 30-45 minutes. Larger samples up to 3,000g or more require longer times. During a binder ignition test, an asphalt sample is heated until the binder portion ignites. Temperature in the main chamber rises substantially above setpoint, peaks, then gradually returns to setpoint as coke-type residual products are burned off. This decoking period is based on user experience with similar mixes or specification requirements. When determining the decoking period to program for a new mix, the sample is merely returned to the furnace for additional 5-10 minute periods until completion is confirmed by stable total weight. As the asphalt ignites and burns, volatilized components of the binder are carried by the exhaust stream into the high-temperature afterburner chamber, where they are compley oxidized. Large amounts of room air are drawn in to quickly cool the exhaust for safe discharge to the outside. Any remaining particulate matter is captured in the disposable in-line filter. The Furnace remains locked during operation until a safe temperature is reached during the cool-down period. The easy to operate controller features large, bright display and a sturdy membrane keypad. Operating temperatures, times, setpoints, and menu functions are displayed. The controller has memory capacity for up to ten timed programs with selected chamber and afterburner time and temperature setpoints. A pre-set function allows starting of the furnace at a specific time of day, so there is no lost time waiting for warm-up. The controller is dual-purpose and can also be used for custom ramp-hold programs with multiple ramps and dwells for glassware cleaning or other applications. The stainless steel case has a drop door to serve as a shelf for ease of sample tray handling. Heating elements are quality Kanthal A-1 and easily accessible for inexpensive replacement if necessary. The Binder Ignition System includes two Sample Baskets, a Basket Cover, Sample Tray and Tray-Handling fork, two ceramic Hearth Plates, Exhaust Filter and Filter Holder. Extra sets of sample tray, basket and cover may be ordered as HMA-69 for more efficient sample processing. SE-31 Heat Resistant Gloves are purchased separay and are highly recommended safety items. The optional HMA-810 all-steel Furnace Support Stand allows safe positioning of the furnace in the lab. Available HMA-813 Sample Cooling Cage protects personnel from hot surfaces as sample is cooling. HMA-814 Exhaust Vent Kit is optional and easy to install for routing warm exhaust gases to the outside. A reliable bench scale of 12kg capacity or more, readable to 0.1g is required; Gilson recommends our AD-12KA or OBX-12KA, listed separay.
