clock 16 minutes | 21 Jun 2021

Two specialists using laboratory equipment

The demands on in vitro diagnostics and laboratory processes has inspired an array of increasingly automated equipment.

This equipment is used to heat, cool, stir, shake, process and analyze medical samples, along with cleaning and sterilizing instruments. Yet despite the introduction of new techniques and diagnostic medical devices, a range of standard laboratory equipment can be found in almost all laboratories.

Designing and engineering laboratory equipment must take into account precision, safety, speed and capacity. Equipment can be grouped into three main areas:

  • Heating & refrigeration
  • Preparation & analysis
  • Sterilization & cleaning

Laboratory equipment manufacturers around the world rely on Essentra Components to supply the critical items that make their medical devices and equipment work, from ultra-low temperature freezers to spectrophotometers. We’ve designed this guide to help you select the components you’ll need for your:

  • Cold storage
  • Hotplates & incubators
  • Clinical analyzers
  • Centrifuges
  • Sterilizers & washers
  • Other laboratory equipment

Most of the components we’ve recommended can be used across different devices and equipment. If you’re not sure which solutions will work best for your application, let us know. We’re happy to provide guidance and expert advice.

Free samples and CAD downloads

To make your job easier, we’ve also made available free samples on most of our solutions, so you can try before you buy. You can also download free CADs of our solutions to help with your laboratory equipment development.

Refrigeration equipment in laboratory

Heating and refrigeration laboratory equipment

Many laboratory processes and experiments involve heating or cooling samples to a specific temperature by boiling, cooling or freezing.


Laboratory incubators control climate, contamination and temperature. Examples include: dry block, hatching, refrigerated, and direct-heat or water-jacketed CO2 incubators, just to name a few.

Water baths

A laboratory water bath is used to maintain a constant temperature for a wide range of lab procedures. This is done by applying a gentle heat to test tubes, beakers, and other vessels.


Electrically heated laboratory ovens are commonly used to remove water or other solvents from samples and even to dry glassware. Applications include drying, baking, aging and sterilization.

Hotplates and stirrers

When steam or water baths are not appropriate, these benchtop tools are used to heat liquids. Hotplates are for heating only, while combination hotplate stirrers are able to heat and mix simultaneously. Infrared hotplates are an energy-efficient alternative. Laboratory hotplate accessories include temperature probes, external digital displays, and heating blocks.

Heaters and heating mantles

Used as an alternative to lab hotplate stirrers and Bunsen burners, heating mantles provide safety and flexibility. The heating element is typically insulated from the container and can be used with various shapes and sizes. The temperature is usually controlled by a rheostat, which makes maintaining temperature simpler.

Microwave ovens

Microwave ovens designed for the laboratory have built-in safety features and operation procedures in order to mitigate hazards not commonly encountered with other heating methods. Examples include rapid temperature and pressure rise, superheating, arcing, and microwave leakage.

Circulators and chillers

Used to heat or cool liquids which can then be transferred via tubing to another location or device. A laboratory chiller can meet temperature ranges of –13 °F to 266 °F, allowing them to heat as well as cool.


General-purpose laboratory refrigerators are used for cold storage of materials within a specific temperature range, usually between 35.6°F to 46.4°F. Features can range from access ports and interior lighting to alarms for temperature change and door ajar.


Used for short or long-term, laboratory freezers store biological, pharmaceutical, and other laboratory samples typically down to -4°F. Ultra-low laboratory freezers operate between -112°F and -58°F. Your design will need integrated temperature recording capabilities to comply with regulations from the FDA and other agencies. Styles vary, as do structural options. Think about shelving or drawers, and solid or clear doors, for example.

Preparation & analysis laboratory equipment

Clinical analyzers

Used to test various properties of clinical samples such as blood, plasma, and bodily fluids to aid in patient diagnosis. A broad range of analysers can be found in a variety of settings, from clinics to research labs and high-throughput hospital labs. They are also used at the point-of-care, such as in physicians’ offices and patient bedsides.

Analyzers are highly automated for speed, consistency, avoidance of contamination, protection of operators from hazardous materials, and walkaway capability. Most analyzers are designed for benchtop use but smaller models are designed for use at the bedside therefore need to be light-weight, compact and portable.

Used to find the precise mass or weight of substances.


USB microscopes are increasingly popular. These are essentially a webcam with a high-powered macro lens using inbuilt LED light sources.

Sterilizing bottles in laboratory

Sterilizing & cleaning laboratory equipment

It’s critical to disinfect laboratory equipment to ensure contamination is at a safe level. Laboratory sterilizers and autoclaves are used in controlled environments almost universally for this purpose.


These are a specific type of laboratory sterilizer, using high-temperature steam within a sealed chamber to treat glassware, plasticware, and equipment. Most of today’s autoclaves are controlled by microprocessors, which enable programmable sterilization cycles. They’re designed as benchtop or floor standing models.

Glassware washers and dryers

Lab washers are similar to domestic dishwashers. They’re designed mainly to clean flasks, bottles, test tubes, containers and instruments. They do not fully sterilize items and are not typically pressurised, but they do use hot water and special cleaning liquids.

X-ray, gamma-ray and UV sterilizers

X-rays and gamma-rays are considered cost-effective, efficient, chemical-free, and environmentally friendly ways to ensure sterilization. UV has limited penetration but is relatively safe so is primarily used to sterilize small areas. X-rays and gamma rays are more penetrating, which makes them more dangerous but very effective for large-scale sterilization of plastic items. Lights, lamps, handheld wands, and boxes or chambers are common applications for these methods.

The components you’ll need for sterilizing and cleaning are:

​Stud-mount leveling feet
