4. When using an expensive kit (like PCR, RT-PCR, etc), determine the
smallest size reaction you need.
RT-PCR kits often recommend running 50 uL reactions - but if you only need
to run 2 gels, 25 uL is all you need. Re-do the math and save 50%.
Case in point:
Regular price for a Boehringer RT-PCR kit:= $ 375 , + $ 50 for RNAse
inhibitor. That is $ 4.25 per reaction if you use 50 uL.
With 25 uL, it's $ 2.13
5.) Watch for sales and stock up, just like you do with your groceries.
There are also coupons for reagents sometimes - use them.
Example: That RT-PCR kit was on sale for $ 188.
($ 188 + $ 50)/200 = $ 1.19 per reaction vs the original $ 4.25 :-)

We do this too. Our lab manager negotiated a special deal where we buy
bags of 10,000 yellow tips because we go through so many.

I use these 2 simple rules:
1.) It can be cheap, but it has to work. If I switch to a cheaper reagent,
I get a sample to test , or negotiate a money-back guarantee.
2.) I calculate my total cost to the department, including stipend and
health insurance. I divide that by the hours I work.
If the money saved is less than my price per hour, it's actually costing
the department more, not less.
P.S. I can rack pipet tips faster than anybody else in the lab because I'm
