Forced air drying — RDO benchtop and RGL vertical ovens for glassware, powders and samples
45L-245L benchtop, 20L-210L vertical, up to 300°C
Drying, curing and sterilizing on one oven platform
Lab Ovens
A lab oven is the quiet workhorse of the laboratory: glassware comes in wet and leaves dry, powders lose their moisture, adhesives cure, and metal parts let go of their stress — all inside the same stainless chamber. What separates a precision temperature oven from a kitchen box is control: PID regulation, a PT100 sensor where the sample actually sits, and uniformity you can document. That is what WSHLab builds. Our laboratory oven range covers five families: forced air drying ovens (benchtop and vertical, 20L to 245L, up to 300°C), vacuum drying ovens (<133 Pa, up to 250°C), high temperature ovens up to 500°C with Incoloy heating elements, industrial ovens from 640L to 1200L with double doors, and dry heat sterilizers for glassware and instruments. Every model carries CE certification and is built in our ISO 9001 production line in Wuhan. If you already know your temperature range, jump to the family below. If you are specifying a lab oven for the first time, start with the buying guide — it follows the same sequence our application engineers use to size an oven for a real lab bench.

TECHNICAL DATA
How every WSHLab oven is engineered
One architecture across the range: a stainless steel chamber with rounded corners, double-wall insulation, a low-noise blower where convection is needed, and a PID controller with self-tuning, timer and over-temperature protection. The differences between families are deliberate — vacuum sealing, Incoloy elements, 316L work zones — not accidents of a single design.

PERFORMANCE & SELECTION
What is a lab oven?
A laboratory oven is a temperature controlled oven engineered for repeatable thermal processes: drying, baking, curing, annealing and sterilization. Unlike a domestic appliance, a standard lab oven holds a constant temperature setpoint with PID control and a calibrated PT100 sensor, and documents it. WSHLab models run from ambient+10°C to 500°C with 0.1°C resolution.
- PID-controlled, PT100-sensed constant temperature oven, resolution 0.1°C
- Stainless steel chamber, rounded corners, easy to clean and non-contaminating
- Double-wall insulation keeps the exterior safe to touch and the interior stable
- Timer, over-temperature alarm and self-tuning on every model
CONFIGURATION & COMPATIBILITY
Types of lab ovens: pick by heating method first
The fastest way to the right model is to decide how heat reaches your sample. Forced air circulates hot air for speed and uniformity; vacuum lowers the boiling point of solvents for heat-sensitive work; high temperature models reach 500°C for annealing and heat treatment; industrial ovens trade bench space for capacity; dry heat sterilizers are tuned for glassware and instruments.
- Forced air drying oven — mechanical convection, ±1°C at 100°C, up to 300°C
- Vacuum drying oven — <133 Pa, up to 250°C, optional nitrogen purge
- High temperature oven — 300°C to 500°C, Incoloy elements, 316L work zone
- Industrial oven — 640L and 1200L, double-door, truck-in design
- Dry heat sterilizer — up to 250°C, ±1°C uniformity, sterilization cycles

QUESTIONS & ANSWERS
Lab Ovens: frequently asked questions
The questions buyers ask most often when specifying Lab Ovens, answered by our technical team.
What temperature range do WSHLab lab ovens cover?
Forced air and industrial ovens run from RT+10°C to 300°C, vacuum ovens from RT+10°C to 250°C, and the RGW high temperature series reaches 500°C. Resolution is 0.1°C across the range, controlled by a PID loop on a PT100 sensor.
What capacities are available?
From a 20L benchtop vacuum oven to a 1200L industrial double-door oven. Popular mid-range sizes are 70L, 90L, 136L and 210L. Shelves are adjustable on every model, so plan around your real load.
Can I get benchtop and floor-standing formats?
Yes. RDO and RZF series are benchtop, RGL and RZFL series are vertical floor-standing cabinets, and the RGF industrial series is a full-height production oven with double doors and casters.
What chamber materials do you offer?
201 stainless steel is standard, 304 stainless is standard on C-series and all vacuum and dry heat models, and the RGW 500°C series uses a 316L stainless work zone with removable shelves.
Do the ovens meet certification requirements?
Every oven is CE marked and built under ISO 9001. Each unit ships with a factory test report; calibration certificates and IQ/OQ documentation are available on request for regulated labs.
