Essential Lab Equipment For A Small Laboratory

Essential Lab Equipment For A Small Laboratory

Setting up a small laboratory can be both an exciting and daunting task. Whether you're a budding scientist, a small research firm, or a school, having the right equipment is crucial for your experiments and studies. 

Here's a guide on essential apparatus for a small lab, focusing on the most important items you'll need:

  1. Glassware: An integral part of any laboratory, glassware is essential for mixing, heating, and storing chemicals. Items like beakers, flasks, and test tubes are fundamental for daily lab activities. 
  2. Balances: Precision is key in any laboratory. A good quality balance is necessary for accurately measuring the weight of various substances.
  3. Plasticware: Often more durable and less expensive than glassware, plasticware is a practical choice for many lab activities. It includes items like plastic bottles, funnels, and pipettes.
  4. Metal & Porcelain: Equipment made from metal and porcelain, such as crucibles, are essential for heating substances at high temperatures.
  5. Silicaware: Silicaware is an indispensable part of a small laboratory for experiments requiring high-temperature resistance and durability.
  6. General Equipment: This includes a variety of tools and devices like microscopes, stirrers, and water baths, which are crucial for a range of experiments.

So, what lab equipment do you need when you have a small laboratory?

Glassware:

Let’s start with glassware. While some can be versatile, like beakers and flasks, if you really need to have an accurate result in your experiments, then you would need to go the extra mile (or buck) and get specific glassware

Plus, having these means that you will have an easier time conducting your experiments and will make less mistakes. 

Here are some of the must-haves for your mini lab:

  • Beakers: These are used for mixing, stirring, and heating liquids. They're shaped like cylinders with a flat bottom and come in different sizes.
  • Flasks: There are various types, like Erlenmeyer and volumetric flasks. Erlenmeyer flasks have a cone shape for easy mixing. Volumetric flasks are used for accurate liquid measurements.
  • Test Tubes: Small tubes used for holding chemicals, heating them, or observing reactions.
  • Burettes: These are long, thin tubes with a tap at the end, used for adding exact amounts of liquids, especially in titration experiments.
  • Pipettes: Tools for moving small amounts of liquid accurately.
  • Condensers: Used in processes where you need to cool down vapor and turn it back into a liquid.
  • Petri Dishes: Small, flat dishes used for growing cells or microbes.

Balances:

Just with glassware, some balances are necessary to achieve the fastest result. But since we’re working with a small space, then it’s better to look at laboratory balances that are versatile and wouldn’t take too much workspace:

  • Analytical Balances: Used for precise measurements in chemical analysis, pharmaceutical preparations, and any application requiring high precision on a milligram scale.
  • Precision Balances: Ideal for tasks needing less precision than analytical balances, such as weighing chemicals for general experiments or preparing solutions.
  • Portable Balances: Suitable for fieldwork or when lab space is limited. They are used for basic weighing tasks where extreme precision is not critical.
  • Top Loading Balances: Commonly used for routine tasks like weighing bulk chemicals or materials where high precision is less critical but speed and ease of use are important.

The most important thing to consider here is what kind of experiments you would be doing and whether it’s necessary to go out of your way and get each kind of laboratory balance. 

Plasticware

There are pros and cons to using plasticware, and if you’d like a detailed guide, you can check it out here. But the most obvious reason why someone would opt for plasticware over glassware is the price. Plasticware is significantly cheaper and is safer to work with specific use-cases. Here are the plastic lab equipment that we recommend when you have a limited workspace:

  • Plastic Bottles: For storing solutions and chemicals, available in various sizes.
  • Graduated Cylinders: Useful for measuring liquid volumes, more durable than glass.
  • Funnels: Essential for transferring liquids, available in different sizes.
  • Pipettes and Pipettors: Key for accurately measuring and transferring small liquid volumes.
  • Specimen Containers: For collecting and storing samples.

For smaller laboratories, plasticware can be a better option than glassware. If you happen to bump into a graduated cylinder, chances are, it wouldn’t shatter and cause harm. There are a lot of factors to consider when opting for glassware, so we recommend checking the article we mentioned previously so you can make an informed-decision. 

Metal and Porcelain

Metal and porcelain laboratory equipment, known for its high heat resistance and durability, is essential in various lab activities. 


Here's a more detailed look:

  • Metal Spatulas and Scoops: These are commonly used for handling and transferring solid chemicals and powders. Common laboratory spoons have a flat end and a scoop end, making them a two-in-one tool for scooping and stirring.
  • Porcelain Crucibles: Crucibles are used to heat substances to very high temperatures, making them perfect for chemical reactions requiring heat. Porcelain is a preferred material due to its ability to withstand these extreme temperatures without reacting with the substances being heated.
  • Porcelain Mortars and Pestles: These are essential for grinding and mixing solid materials. Porcelain is ideal for this task due to its hard, non-porous surface, which is easy to clean and does not absorb chemicals.
  • Metal Tongs and Clamps: Tongs and clamps are necessary for safely handling hot equipment and containers, particularly in procedures like heating or sterilisation. You don’t want to jump when you touch a hot surface in your small lab, right?

Silicaware

Let’s say you have more money to spend on your labware but not enough to spend on glassware? Well, silica might be what you’re looking for. As the name implies, it’s made from silicone; a durable, flexible, and heat-resistant material. 

Since most glassware has a silicaware counterpart, your decision-making all boils down to use-case and budget for your compact lab setup.

General Equipment

These are lab equipment you would commonly find in school laboratories and small, privately-owned labs. What we mean by these are a broad range of tools and devices essential for various tasks in scientific research, experiments, and daily lab work. 

  • Safety Equipment: Safety first! Even a small lab should be equipped with basic safety gear, including fume hoods to evacuate hazardous fumes, and personal protective equipment like gloves and goggles.
  • Bunsen Burner: A staple for heating chemicals, sterilising small tools, and performing combustion experiments. It's compact and easily regulated for temperature control.
  • Refrigerator and Freezer: A compact combo is essential for preserving samples, reagents, and biological materials that require cold storage.
  • Hot Plate: An electric alternative to open flames, hot plates provide a stable heating surface and are essential for tasks requiring consistent heat application, especially when flammable materials preclude the use of a flame.

Each piece serves a specific purpose and they all have two things in common: to make your time in the lab easier so you can focus on analysis and provide accurate, replicable results.

Final Thoughts

When setting up a small laboratory, the key is to prioritise space, versatility, and safety. Essential equipment like Bunsen burners, labware that fits your budget and needs, and safety equipment are fundamental. Choose compact, multi-function devices when possible to maximise your limited space. Protective equipment should never be compromised, regardless of the lab's size. 

Remember, the right tools will not only save space but also allow for a wide range of experiments and encourage efficient workflow in your mini lab setting.
