Common Types of Laboratory Ovens

Despatch offers a variety of lab ovens to meet the specific needs of different applications:

  • Forced Air Convection Ovens: These ovens ensure even heat distribution throughout the chamber, making them ideal for drying, baking, and curing processes. They offer rapid heating capabilities and temperature ranges from +10°C to 600°F (315°C) or higher.
  • Gravity Convection Ovens: Best suited for tasks requiring less temperature uniformity, such as sterilizing and curing. These ovens have temperature ranges from +25°F to 450°F (232°C) and feature natural air circulation for energy efficiency.
  • Vacuum Ovens: Combining heat with vacuum pressure, these ovens are perfect for drying heat-sensitive materials gently and efficiently. They are used for sterilization, removing solvents, and dehydration with temperature ranges from +25°F to 500°F (260°C).
  • High-Temperature Ovens: Designed to withstand extreme temperatures from 250°C to 1200°C (482°F to 2192°F), these ovens are suitable for demanding applications like curing, annealing, and preheating, offering rapid heating and cooling.

Lab Oven Applications

Lab ovens are versatile instruments essential in many scientific disciplines, including materials science, chemistry, pharmaceuticals, environmental science, electronics, and forensic science. These ovens are used for a wide range of applications:
  • Drying glassware and lab equipment
  • Sterilizing surgical instruments and laboratory tools
  • Evaporating solvents from chemical samples
  • Incubating cultures at precise temperatures
  • Curing materials like coating, adhesives and polymers
  • Conducting material testing with high stability and repeatability

Despatch lab ovens are designed to provide maximum versatility in compact spaces, ensuring that research activities are carried out efficiently without compromising on precision.

Key Consideration for Choosing a Lab Oven

When selecting a lab oven, consider the following factors to ensure the right fit for your research needs:

  • For vacuum ovens, consider vacuum level, chamber size, and material compatibility.
  • For gravity convection ovens, look at temperature range, energy efficiency, and ease of use.
  • For forced air convection ovens, evaluate temperature range, airflow uniformity, and noise level.
  • For high-temperature ovens, consider temperature range, insulation, and power requirements.

Benefits of Using Despatch Lab Ovens

Every Despatch lab oven, except for the LBB series, is equipped with the Protocol 3™ microprocessor-based temperature and hi-limit controller, which features a large LCD display. This system offers advanced data-logging capabilities for reporting, analyzing, and exporting data via a USB port. The optional software allows for remote oven control from a computer, recording critical information such as times, temperatures, set points, alarm conditions, and lot numbers. The data can be saved in an editable format, easily integrated into Excel.

They’re designed to offer maximum versatility, making them ideal for a wide range of scientific and industrial applications, including drying, sterilization, curing, material testing, and incubation. Their unique horizontal airflow system delivers uniform heating across all shelves, ensuring consistent and reliable results, unlike most lab ovens that use vertical airflow. This design feature is achieved through a high- volume fan that circulates air through perforated stainless steel walls, creating constant horizontal airflow for shorter cycle times and controlled ramp rates. Despatch lab ovens are constructed for durability and ease of maintenance. They feature stainless steel interiors, smooth door surfaces, sturdy welded double-wall construction, thick glass fiber insulation, and heavy-duty door gaskets. Each oven undergoes rigorous quality and performance testing before shipping, ensuring reliability. Heating elements come with a five-year warranty.

They offer:

  • Vacuum Ovens: Efficient drying for heat-sensitive materials
  • Forced Air Convection Ovens: Quick and uniform heat distribution.
  • Gravity Convection Ovens: Cost-effective for general drying and heating.
