INSIGHTS on Fume Hoods

Aside from safety, saving energy is the trend in fume hoods these days. Hoods are energy hogs that suck thousands of cubic feet of conditioned air per hour, 24 hours per day, out of buildings; replacement air must be heated or cooled depending on the season.

“Fume hoods are tremendously expensive to run,” notes Dana Dahlgren, VP of sales and marketing at Kewaunee Scientific (Statesville, NC). “The last decade has been all about fume hoods that are more efficient, that do not require the same air flow as older models.”

Facility managers increasingly specify variable air volume (VAV) systems for new buildings. VAV uses a combination of sensors and controls that ramp down exhaust in individual hoods according to demand.

Product of Interest

Technical Glass Products, Inc. Opaque Fused Quartz

 


The opaque quality comes from quartz sands of high purity when reduced to a molten state at a temperature of approximately 2000° C. The high temperature produces a vitreous material characterized by the presence of a multitude of gaseous micro-bubbles. These bubbles diffract light, giving the material its opacity. The term opaque silica is mainly used for molded or centrifuged parts, while the product obtained by drawing is normally referred to as translucent.

RDM Industrial Products Inc. SB-MAX


The SB-MAX BenchTop Fume Hood is one of our most popular models. This unit provides multiple standard and optional features for air control, including optional Add Air (Make-up Air) System. This Fume Hood is ideal for most laboratory exhaust application needs. The narrow design of the hood allows easier installation by enabling it to fit through the width of a standard doorway opening.

Help your Colleagues

Plenty of discussions are happening on LabWrench all the time. We have many questions come in daily from users that are seeking advice from fellow users and lab professionals on LabWrench. Can you help any of these users find the answers they are looking for?

License error
License error with 8453 spectrophotmeter device even though winsotax plus installed and audit trail fine. Any ideas? Advise this member.

Air flow rate
Will the Aura 550 capture isoflurane gas in the carbon filter? Is the fpm too fast for capture in the filter? Is there any way to tell if the filter is saturated? Advise this member.

Distek ezfill 4500
We have had one of these for 2 years, and recently it started playing up. I have never seen something so screwed down, In terms of not allowing access to the insides to figure out what has gone wrong. Turns out the plasic acme nut on the drive has just worn out and is no longer able to drive the actuator. I find it worrying that this costly piece of equipment seems to have lasted only 2 years? Advise this member.

Questions from the Vault

We have so many questions filling our forums that sometimes questions can be missed and go without answers. Can you help us provide answers for these users with unanswered questions?

Readings are incorrect
I am looking for a protocol (and filters) to calibrate my spectrophotometer or recommendations for a service that can calibrate it for me. I have a Milton Roy Spectronic 301. Advise this member.

Genesys S10 errors when turning on
I have to turn on several times due to errors telling be to check the sample compartment then press enter. I found if I hit escape it works in uncalibrated mode then I turn off and on again and sometimes it works. Advise this member.

Fiber Opt Diss Comparison with HPLC
At this time I'm a new user with the Fiber Optic Dissolution system. I did a trial run and compare the results perviously tested using the HPLC. When I looked a the results I do have a 10% more of the HPLC % Dissolved. Is there % comparison? Advise this member.
