Formally known as the Micron Air Jet Sieve, the new and improved Mikro Air Jet Sieve™ is an accurate and reliable single-sieve system made in the USA for separations of 10 to 100g samples of dry powders from 4.75mm to 20μm (No. 4 to No. 635). A rotating slotted nozzle supplies positive air pressure to gently fluidize the sample in a covered 200mm or 8in (203mm) diameter sieve. Exiting air is drawn downward with an external vacuum system, creating a negative pressure that carries undersize particles to a collection canister. Air Jet sieving action is gentle, effective and optimal for fragile or low specific gravity materials. Operation is clean, quiet, and takes up minimal space. An integrated computer with touch screen display easily controls test times and vacuum/pressure settings while storing up to nine preset test times, for ultimate repeatability.
The redesigned Mikro Air Jet Sieve™ now accommodates both 200mm test sieves and conventional 8in (203mm) ASTM Test Sieves with use of an O-ring for sealing. Air Jet Sieves are constructed with stainless steel frames and mesh, and are ordered separately by required mesh size. Low-Profile O-rings adapt Gilson 8in ASTM E11 Test Sieves for use with the Mikro Air Jet, and are available separately. Multiple particle sizes can be determined by transferring retained samples on a fine sieve to the next larger sieve. Inquire for special 83mm diameter sieves and adaptor plate for small or fragile samples that allow three sieves to be used at once.
AJ-103 Basic Mikro Air Jet SieveTM consists of the base unit with a clear acrylic sieve cover, slotted brass air nozzle, electronic controls with integrated computer and touch screen display. The 15 Watt bevel-gear motor has lifetime lubricated bearings. The cast aluminum instrument housing features a built-in pressure differential gauge. An integral electrical outlet provides a convenient connection for the vacuum system, purchased separately. Vacuum is monitored at the housing outlet and has a control valve for adjustment.
AJ-105 Advanced Mikro Air Jet SieveTM includes everything that the AJ-103 Basic model has, plus features for automatic collection of sieve and fraction weights, calculation and reporting of results, and networking and printing functions through the user’s computer. Test results can be reported in a variety of graphs and tabular formats, and saved directly to the computer. A serial interface cable is included. This model or upgrade requires an AJA-135 Electronic Balance, purchased separately.
You can take advantage of the features of the Advanced Air Jet Sieve by ordering the AJ-105 model directly, or by purchasing the simple AJ-111 upgrade procedure to unlock all of the features on an existing Basic model.
