LAMINAR FLOW HOODS
These finely crafted laminar flow hoods produce a localized sterile environment in which to conduct inoculations. Made of durable 7-ply maple hardwood. A powerful fan pushes air through a 99.99% efficient .3 micron filter, screening out nearly all spores or contaminants. Each filter has been scanned centimeter by centimeter and is fully guaranteed. The cost of a hood is quickly offset by the cultures, time and money saved. These hoods have been designed specifically for mushroom culture by a practicing mushroom cultivator. They can be offered at such low prices because we are the manufacturers. They have been designed specifically for mushroom culture by a practicing mushroom cultivator. The Series II and Series III Laminar Flow Hoods feature a universal-current blower that works with both 115V/60Hz and 230V/50Hz current. Hoods are in stock at most times.

The Series I Hood FP's least expensive Laminar Flow Hood now comes pre-assembled! All you need for final assembly is a length of electrical cord for the fan, a screw driver and caulking gun. This unit comes complete with a scanned, 99.99% efficient 24 x 12 inch HEPA filter, fan, 5-ply birch housing, screws and brass handles. Ideal for "on the road" tissue culture or for use in small clean-room environments. For those who have a limited budget, the Series I is uniquely affordable. LFHI $529.00  LFHIE for 230V/50Hz applications $539.00

The Series II Hood Our popular deluxe model that conserves space while providing 50% more working area than the Series I Hood. Comes complete with prefilter housing, fan and scanned 99.99% 24x18 HEPA filter. The Series II Hood is currently in use in government laboratories, professional spawn laboratories and home cultivation operations in this country and abroad. LFHII $1049.00

The Series III Hood This is a professional Laminar Flow Hood for the serious mushroom grower. Utilizing a scanned 36x24 99.99% HEPA filter, the Series III provides enough room for two tissue culturists working side by side. Comes complete with prefilter housing. LFH III $1345.00

The Series IV Hood Our top-of-the-line Hood utilizes a gigantic 48x24 inch, scanned HEPA filter and a powerful 1/3 HP blower. Truly the "Cadillac" of Laminar Flow Hoods! Comes complete with prefilter housing. LFHIV $1595.00

Self-Contained Drop-In Air Filtration Unit This handy all-in-one unit is designed to fit in most ceiling grid systems, simplifying installation in your culture lab or other clean room. Features a 24 x 24 or 48 x 24 inch HEPA filter that filters airborne particles down to .3 microns with 99.99% efficiency. The built-in three speed fan runs between 500 and 850 CFM, which can provide sufficient clean air for 10 air exchanges per hour in a 1,000 square foot laboratory (assuming an 8 foot high ceiling), and generates only 48 dB of noise. The sturdy metal housing includes a 20 x 20 inch prefilter housing to extend the life of the filter (prefilter not included). This unit can be operated both horizontally and vertically, making it ideal for everything from permanent installation in culture laboratories to quick-setup spot filtration where you need it. (Note: these units are designed for general air filtration. Because of its relatively low air velocity [approximately 106 feet per minute], the MFDI4824 is not suitable for use as a laminar flow hood; it does not generate a powerful enough air flow to keep airborne particles from entering your sterile work area. At 212 feet per minute, the MFDI2424 has sufficient air velocity for this purpose.) Comes fully assembled. Please Note: This unit must be shipped via Freight Carrier; it cannot be shipped via normal Postal, UPS or FedEx service. If you purchase this unit online, the order will be placed on hold until a Customer Service representative can contact you with a shipping quote. Estimated shipping per unit: $120.00.

High Efficiency Particulate Air (HEPA) Filters Custom manufactured to FP's critical specifications, these scanned water resistant micron filters are stocked in six sizes and screen out all airborne contaminants down to .3 microns with a guaranteed efficiency of 99.99%. All of these HEPA filters operate at .8 inches of static pressure. Individually scanned and tested for quality. These filters are used throughout the microbiological industry and by computer manufacturers, nuclear laboratories, photographers, and anywhere else clean air is a must. MF1212 12 x 12 x 5.8 inches $89.95  MF2412 24 x 12 x 5.8 inches $129.00  MF2418 24 x 18 x 5.8 inches $159.00  MF2424 24 x 24 x 5.8 inches $229.00  MF3624 36 x 24 x 5.8 inches $289.00  MF4824 48 x 24 x 5.8 inches $349.00

Electrostatic Air Filters A cleanable, replaceable electrostatic filter that screens out contaminants down to 1 micron with a 99% efficiency. These filters are especially applicable for primary air filtration into sterile laboratories and/or growing rooms. (They are, however, not recommended as a component for a laminar flow hood as filter efficiency is inadequate. HEPA filters are rated at a much higher order of efficiency, 99.99% at .3 microns. This difference is significant.) Installing an Electrostatic Air Filter at the "upstream" end of your laboratory or grow room air filtration system can add years of life to your HEPA filters. Dimensions: 22 x 21 x 7 inches. Efficiency is optimized at 1000-1200 CFM. Pressure drop rated at .23 inches at 1200 CFM. EAF2221 $599.00

In-Line Micron Filters Designed for in-line filtration of liquids or gases. Particularly useful for in vitro laboratory experiments. Holder is made of tough, transparent polycarbonate, so assembly can be checked and filtration can be observed. Unit can be used for either vacuum or pressure filtration. Unscrew unit to insert 47mm membrane, which is supported on both sides by polypropylene plates. Biologically inert silicone 0-ring seals the membrane and prevents bypass. Removable tubing connectors on either end fit 3/8 inch ID tubing. Holder with membrane is fully autoclavable. Overall length, including tubing connector: 100mm (nominal). Diameter 65mm (nominal).

FP's Laser Particle Counter A remarkable money-saving instrument that provides an accurate assessment of airborne contamination. Measuring to .3 microns, this hand-held unit samples air in 1/10 of a cubic foot in one minute, using a built-in laser to detect quantities of pathogen sized particles. (Laser life expectancy: 30,000 hours) Ideal for not only measuring clean-room integrity and scanning HEPA filters, the Laser Particle Counter is exceptional in its usefulness for tracking vectors of contamination. This portable unit has a rechargeable internal battery which allows for 3.5 hours of continuous operation. Paul Stamets notes, "This is the single most valuable tool I have used in nearly 20 years of tissue culture." LPS229 $3,095.00  LPS229E for 230V/50Hz applications $3295.00
