‘be good in the hood’
ALWAYS close the sash thermoscientific.com safest position.
‘be good in the hood’ do not store unnecessary items in the hood
‘be good in the hood’ being good in the fume hood not only ensures your safety but it also saves energy
tissue culture hoods med.cam.ac.uk newvoiceforresearch.blogspot.com
tissue culture hoods: how they work ars.usda.gov
tissue culture hoods energy consumption 1 – 12.6 kWh/day depending on usage -manufacturer data 0.3 – 0.6 kWh/day per UV lamp -manufacturer data
‘be good in the hood’
turn hood COMPLETELY off thelabworldgroup.com prevents UV damage to reagents and staff
‘be good in the hood’ being good in the tc hood not only ensures your safety and prevents unnecessary UV damage to hood contents but it also saves energy
ultra-low freezers
ultra-low freezers: -80 energy consumption 15 – 20 kWh/day -manufacturer data -validated by monitoring
‘-70 is the new -80’
chill up freezers from -80 to -70 save 2-4kW per day
DOE ‘-70 is the new -80’
clean freezer coils, regularly defrost freezer save 12-25% energy other best practices for ultra-low freezers prolong lifetime of the freezer
perform scheduled maintenance on freezers other best practices for ultra-low freezers prolong lifetime of the freezer
remove old, unneeded samples other best practices for ultra-low freezers fewer samples stored, fewer freezers are needed
transfer samples to other storage paradigms -20 freezers ambient temperature storage containers other best practices for ultra-low freezers fewer samples stored, fewer freezers are needed
lasers laserfest.org
lasers: types gas lasers solid state
lasers: gas energy consumption 15 – 120 kWh/day -manufacturer data
exchange gas lasers for solid state lasers could save a minimum of 50% energy -manufacturer data best practices for lasers solid state lasers last longer, lower maintenance costs
prolongs lifetime of the laser saves energy best practices for lasers turn off (gas) lasers when not in use, especially over the weekend
microscopes
mercury-free microscopy
mercury/metal halide bulbs mercury-free microscopy
mercury/metal halide bulbs 5000 hours/mg Hg 2.5 hours/mg Hg 1 bulb 2000 bulbs mercury-free microscopy
recycle used mercury and metal halide bulbs
energy consumption illumination: 0.12 – 6 kWh/day -monitored by My Green Lab other best practices for microscopy
exchange mercury/metal halide for solid state light sources savings 25 – 90% -monitored by My Green Lab other best practices for microscopy less toxic, cost less to own, in many cases are better for samples
cost of ownership of microscope illumination sources MERCURY ARCMETAL HALIDESOLID STATE Replacement bulbs15015n/a Total Bulb Costs$22,500$10,500$0 Total Liquid Light Guide Costs n/a$5,250$0
LED comparison with metal halide: stability
LED comparison with metal halide: ‘brightness’ metal halide (300hrs) v. sold state
LED comparison with metal halide: energy consumption
other best practices for microscopy turn off microscope equipment when not in use prolongs lifetime of the equipment saves energy
large centrifuges djblabcare.co.uk
large centrifuges energy consumption 0.7 – 6 kWh/day -manufacturer data
store rotors at 4 C energy savings minimum 10% best practices for large centrifuges saves time
turn centrifuge off after use savings minimum 10% best practices for large centrifuges prolongs lifetime
heating blocks phenixresearch.com
heating blocks energy consumption 0.5 – 12 kWh/day -S-labs
best practices for heating blocks turn them off when not in use energy savings minimum 10% prolongs lifetime improves safety
autoclaves oh.water.usgs.gov lightlabsusa.com
autoclaves: types stand-alone bench-top
autoclaves water consumption 90 gallons hot water per cycle 22 gallons cold water for effluent cooling -UCSB
autoclaves University of Edinburgh autoclaves accounted for 41% of the total energy usage on campus energy consumption
combine loads use a smaller, research –grade autoclave best practices for autoclaves keep autoclave in ‘standby’ rather than ‘on’
water tap water distilled water deionized water ultrapure water
water tap water distilled water deionized water ultrapure water purified
distilled water (ddH 2 O) energy and water intense
deionized water (DI) pre-treatment reverse osmosis polishing (deionization) UV sterilization, final filtration usually stored 50% efficient
ultrapure water: Millipore (MilliQ) goes through a filter 35-50% efficient, larger systems more efficient -UCSB
only use what is necessary – keep in mind that what you use is just a fraction of the total water being used recycle filter cartridges through Millipore best practices for water consumption
