Bulk Buying for the Lab – When Stocking Up Saves Money and When It Doesn’t

Laboratory worker organizing supplies and inventory

Having plenty of stock in your stockroom is great. Fewer orders, fewer deliveries, and you get a lower price per box.

The problem with bulk discounts is they won’t save you money if you have too much product sitting around that will expire.

Whether your lab uses products from pipette tips to research-grade peptide blends, there is a question you need to ask yourself. How much will you use?

If you can answer that question, you may end up saving more money than you thought.

When To Buy In Bulk

There are some situations where buying in bulk is beneficial. If you are ordering the same product that is used frequently. And it does not take up much space to store.

You can save on unit price, reduce delivery fees, and save your staff time from doing repetitive tasks.

Buying in bulk can also help you if you ever run out of stock from your supplier. Or if your supplier is delayed in shipping your order.

Having extra stock on hand will benefit your lab if you have frequent orders for certain tests.

Just remember that not all products are made equal when buying in bulk.

Buying Research Material In Bulk

As stated above, not all products are the same when buying in bulk. Products that are bought to do research on should not always be bought in bulk.

There is a big difference between a box of gloves and a research material that is being ordered to do an experiment on.

When buying research-grade peptide blends vs. single compounds, you should look into what your experiment will need.

Maybe you are using the GLOW research blend to do some in vitro research. Since this product is a combination of 3 peptides, it should be taken into consideration before buying multiple vials.

Make sure you understand what you will be needing before buying multiple vials of any product. Read up on the product, its lot number, and any instructions.

Always keep track of your lot number when doing research. If you happen to switch to a different lot, you can go back and look at it.

If your method is still being created, you may want to buy a lower quantity until you know what your research will call for.

What You Are Not Saving On

When buying in bulk, you think you are saving money on unit price.

Well, there are other factors to consider when buying in bulk.

Space is one factor to think about. Having extra product will take up space in your lab. Maybe that product requires cold temperatures. You now have to store those items in a refrigerator or freezer.

Keep in mind the lifespan of your products as well. Always date your products when they come in and use the oldest supply first (if it can be).

Your product could expire or go unused if your method changes.

Also keep in mind waste disposal when buying chemicals in bulk. Unused chemicals may require controlled disposal, which can add costs and staff time.

Make sure your order fits your lab’s needs and ability to store the product.

Buying in bulk could end up costing you more money than you thought.

How do you know what your lab will need when buying products in bulk?

How To Find Out What You Will Use

By keeping track of what you are buying and what your lab uses.

Suppose you can buy 100 units of a product for $80. Or buy a box of 25 for $25 each.

If you know your lab will use 100 units, the box of 100 is a better deal for you. You will be paying 80 cents per unit instead of $1 per unit.

But if your lab only uses 40 units before they expire or your lab stops needing them. You paid $80 for 40 units that you used. Which means you are paying $2 a unit for that product.

If you bought 2 boxes of 25, you would only pay $50 for the 40 units you used. So you are only paying $1.25 a unit.

In this case, buying 2 boxes of 25 units was the better buy for your lab.

By knowing what your lab will use, you can make a smart decision on buying products in bulk.

In a 2026 survey of medical laboratory professionals by Medical Laboratory Observer, 66% of respondents reported evaluating inventory levels for basic supplies as a way to improve inventory control and consumable costs.

Making Rules For Your Lab

There are many ways you can create a system to buy products in bulk for your lab. One way is to have a spreadsheet that everyone can access and update when products are bought or used.

Make sure to check what you currently have on hand before buying in bulk.

Make a list of what your lab will use and what you already have on hand.

Check to see if the product will last long enough to be used before it expires.

Find out how much it will cost to receive, store, and possibly dispose of your product.

Maybe your supplier will offer to deliver your product to you at a discounted price if you buy in bulk, but allow them to deliver to you over a period of time.

Depending on the product, this may be a good option for your lab.

Have a person designated to keep track of your orders and when they were received.

If you buy products that multiple departments use, make note of how much each department is using. You can use this to your advantage when deciding if you should buy in bulk.

Stock Up Vs Have On Hand

A small backup supply can be useful when a delayed delivery could stop regular lab work. Decide how much to keep by comparing normal usage with supplier lead time and the item’s shelf life.

This can apply to any product you buy for your lab.

Summary

Buying in bulk can save your lab money. Just be smart about what you buy in bulk and what you should buy in smaller quantities.
