15 Laboratory Items You Can Buy In Any Store
A variety of lab supplies can be purchased off the shelf in your neighborhood, which can save you time and money, especially when compared to the added cost of shipping, handling, and markup of various items when ordering from lab vendors (*your mileage will vary).
How to Get Reimbursed
The method for procuring supplies on your own dime is a bit different than going through the ordering process in the lab. Typically, once you OK the need with your lab manager, you’ll go purchase the item yourself, bring back a receipt, fill out a reimbursement form, make copies of everything, submit it, and wait for the department to approve it and pay you back from lab funds. It’s not too complicated—though, patience is a virtue.
Items that can be purchased virtually anywhere
While it may be quicker to ask a neighbor to borrow a cup of sugar before buying it at the corner store, here is a grocery list full of useful items that you can stock your lab with today!
1. Office Supplies
Highlighters, permanent markers, shipping labels, and note cards are the items I live by. On a good day, they are fantastically inexpensive; there is a variety of items for any administrative need.
2. Aluminum Foil and Plastic Wrap
Reduce your costs significantly by buying in bulk (And stock the lab for months—possibly years). Purchase items by the thousand feet, the gallon, or case to see unit costs shrink…while watching your savings grow.
3. A Personal Centrifuge
Harness a little ingenuity to build your own custom, portable green-energy centrifuge for a quick spin down of samples (not salad). Here’s one way to begin the modifications using a plastic spinner. 
Your graduated cylinder takes the guesswork out of precise measurements however you can look to the kitchen aisle for large containers for media preparation. If you’re interested in utilizing home-style measuring tools, be sure to brush up on your Imperial to Metric conversions before use.
5. Plastic Funnels
To the kitchen aisle again (or the auto parts store): a funnel is what you need to avoid costly spills when pouring liquids from a wide-mouth bottle into a narrow-mouth bottle.
Do-it-yourself with a commercial-size package of coffee filters. Larger particulates can be strained with cheesecloth.
For those who use actual timers (and not smartphones), count down to the end of your experiment with an egg timer. When more specificity is needed, go digital.
Interestingly enough, a consumer scale will measure up to the function and precision of your everyday bench scale. Place your weigh boat and turn it on to find that some models will automatically tare for you.
9. Insulated Lunch Buckets
Now the ubiquitous, foam laboratory ice bucket has become hard-sided and rugged, with a closing lid and carrying handle. This multi-purpose item helps make transporting samples across campus easier and safer.
Reserve the expensive, larger-than-life-sized calendars for shared-use rooms and for group scheduling. In your own space, decorate with what interests you – cats, dogs, tropical getaways or print your own calendar.
Consumer gloves come in all types, vinyl, latex, and even nitrile. Keep your eyes open for the 100 (not 50!) count boxes.
Stools and metal chairs for the lab; posh executive-style leather chairs for the offices. Research doesn’t have to be a backbreaking endeavor.
13. Bottle Brush
For all those difficult-to-clean cylinders and glass bottles…bottle brushes are easily found in the baby aisle.
14. Isopropyl Alcohol
Now you’re all set to continue tabletop DNA extractions when you combine a few items from the lab and a few items from this list!
15. Other Chemicals
What do you say about using store-bought chemicals in the lab for your research? If this seems too wild of an idea (or if it’s something you’ve done before), tell us in the comments below. We’ve successfully utilized mineral and corn oils, dehydrated milk, cornstarch, and baking soda.

Razor blades. Pyrex bake pans (for washing blots, as a spill pan for messy things). Tupperware sandwich containers (for staining/destaining/storing gels). Old spoons (pick them up at tag sales and use instead of spatulas when you weigh things out.
I’ve got a million of these:
Coffee grinders (used with liquid nitrogen-frozen samples). One lab I was in washed the coffee grinders after use by submerging them in soapy water. I was sure I was going to be electrocuted, but the key is to let them air dry for a long time – like a week. Most of them still worked after this (for multiple uses), but you will have some that just die.
Blenders – although the professional stainless steel ones are better for most lab stuff, the regular ones are a lot cheaper. Be sure you’re not doing something that can make it explode or crack, of course.
If you lab will let you, purchasing refrigerators from non-science places is usually a lot cheaper than from scientific vendors. Of course it won’t be explosion proof or anything fancy, but a lot of lab fridges are the same as home ones, with a different name plate and a 500% markup.
Very Nice list. However i wanna add from my side, i had worked initially as microbiologist and doing my research on a protease so checking their activity on plates, i require casein but almost never i used that. I replaced it with grocery store milk powder.
