FunnelFit pre-formed conical filters

March 5, 2012

FunnelFit pre-formed conical filters are suitable for organic extract drying applications. They are designed to fit the funnel perfectly every time, which eliminates the need to use costly solvents for wet-down and to keep quadrant-folded or pre-pleated filters in the funnel. FunnelFit filters ensure reproducible, high-quality results by avoiding inconsistent and time-consuming preparation steps that may cause sample bypass, tip blow-out, and contamination. Available in three quantitative ashless grades, they are conveniently packaged in stacks of 100 for fast and easy handling.

Die-Cut Membranes

March 5, 2012

Custom precision die-cut membranes are manufactured to specification using a proprietary process that produces smoother edges than compression cutting and is performed in a clean, positive-pressure facility. They can be produced from a dxf, pdf, or almost any type of drawing file, are made from polytetrafluoroethylene (PTFE), nonwovens and other materials, and can incorporate intricate shapes, including narrow cross-sections and close hole spacing. Membranes as small as 1 in.2 with ±0.005 in. tolerances can be supplied on rolls, with or without an adhesive backing.

Model 6V

March 5, 2012

The Model 6V employs a specially formulated collector tube that skims oil from the surface of water. The oil adheres to the outside of the closed-loop tube, which is slowly drawn across the surface of the water and into the skimmer. Scrapers remove the oil, which accumulates in a collection chamber. The clean tube then returns to the water to skim more oil. The tube automatically adjusts to varying water levels and is flexible enough to wind over and around floating debris. The system can skim up to 100 gal/h, and is designed to operate 24/7.

Witte 300 screener

March 5, 2012

A modular design allows the addition of a vibrating fluid-bed dryer, cooler and deduster to the Witte 300 screener, even years after the original equipment was installed. Combining multiple functions in a compact, quickconnect/ disconnect unit saves floor and overhead space and allows the unit to be moved among multiple production lines. Because the screener can be retrofit to handle additional functions, processing capabilities can be expanded without replacing the screener or buying a separate dryer or cooler.

Roto-Pulse

March 5, 2012

The automatic, incrementally rotating Roto-Pulse uniformly cleans 30–40% more filter surface than conventional reverse-pulse systems. The additional area of clean media means a lower air-to-cloth ratio requirement, lower grain loading, more-efficient filter cleaning, and longer filter life. The system operates by pulsing air into a specially designed stainless steel perforated tube.

Centra-flo Upflow Filter

March 5, 2012

The Centra-flo Upflow Filter can be used in virtually any application requiring the removal of suspended solids. It combines an upflow design with deepbed sand filtration and continuous cleaning to achieve high-quality filtrate with consistently low head loss at varying flow rates. The upflow filter provides a continuous supply of filtered water without interruption for backwash cleaning, making it unnecessary to shut down for backwashing. In addition, the continuous backwash design provides a steady reject stream that eliminates backwash hydraulic surges.

Type IVE mechanical isolation valve

March 5, 2012

The Type IVE mechanical isolation valve prevents hot particles, glowing embers and flames from passing through interconnected piping and potentially starting a fire that spreads from one vessel to the next. The valve remains open until receiving a signal from either a pressure transmitter and/or optical sensor that detects hot particles, embers and flames. Once signaled, the valve closes within milliseconds. Actuation occurs by means of a tank of compressed air located at the valve, which ensures the fastest responsepossible.

Purair 20 ductless fume hood

March 5, 2012

The Purair 20 ductless fume hood protects operators from hazardous substances, because all mechanisms in the head section of the unit are on the clean side of the filter, preventing contamination. Switches and electrical components are isolated from dirty airflow and kept away from contamination, and the work area has a removable spillage tray that can easily be cleaned. Filters can be chosen from 14 types of carbon, including specialty media suitable for organic, solvent, acid, mercury and formaldehyde vapors. The standard hood measures 49 in. wide by 27.5 in. deep by 47.5 in.

Bond-Rite Grounding Clamp

March 5, 2012

The Bond-Rite intrinsically safe hazardous-area grounding clamp protects against static electricity buildup in portable equipment. It creates and continuously monitors a low-resistance connection to ground, while providing visual verification with a flashing light-emitting diode (LED) indicator. Its redesigned electronics module provides enhanced battery/working life, effectively doubling the life of its internally mounted lithium battery. Its inline Quick-Connect feature allows quick and easy field replacement of the clamp and/or retractable cables.

KleenGuard hearing protection devices

March 5, 2012

KleenGuard hearing protection devices include various earplugs and clips. The H50 multiple-use ear clips have a lightweight chassis and removable foam ear pads that fit comfortably and block unwanted workplace noise without needing to be inserted into the ear canal. H30 multiple-use ComfortFlex earplugs have an inner stem that conforms to the natural curves and shape of the ear canal for a custom fit. H20 reusable earplugs have a ridged system for easy insertion and removal from the ear canal, and three soft flanges that collapse to provide an effective fit.
