Top 6 Signs That You Should Service or Replace Your Fume Hood

  1. The fume hood fails to pass a filtration efficiency test but the filters are in good condition. In other words, the product is no longer keeping employees safe.
  2. Degradation of materials. This includes a physical discoloration of the materials, such as etching of steel, fogging on the glass barrier or window, or loud noises coming from the internal fan of the ductless or, in some cases, ducted unit.
  3. You require better containment of a larger number and variety of chemicals, and a higher safety level.
  4. Your current fume hood has broken down, and repair costs are too high.
  5. There is a decline in mechanical functionality (sash movement, etc.).
  6. You have an older, less efficient model that is becoming too expensive to operate.

 Featured Question and Discussions

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?

Brookhaven Instruments ZetaPlus - Zeta Potential measurements off
We've been testing the BI-ZR3 reference material to make sure we're doing the sample preparation and everything right. We're getting the right conductance (~320uS), the particle size (~300nm) approximate count rate (540 kcps). But our zeta potential has been higher than what it should be (-37mV instead of -52mV). The frequency is also lower (223 Hz) than what the manual says it should be (250Hz). What could we be doing wrong to get the higher zeta potential readings and lower frequencies?  Click to respond.

Bioscan AR-2000 Print Problem
We cannot print from Bioscan AR-2000 Sw. The printer is working. But the software cannot find the printer. How can I configure my HP Deskjet 825C printer in AR-2000 sw? Help this member.
