DRYSC Benchtop Drying Oven · Forced Air · LED Controller · 43 to 225 L · up to 250 °C
The DRYSC benchtop drying oven dries, heats and sterilises glassware and samples from 10 °C above room temperature up to 250 °C. A fan moves the hot air horizontally through the low, wide chamber, and a PID controller with LED display holds the set temperature. Four sizes share the same functions: 43 L (PRO3106), 71 L (PRO3107), 136 L (PRO2990) and 225 L (PRO3108).

Every DRYSC benchtop drying oven has the same controller and fan; the four sizes differ in chamber size and heating power. Not sure which size you need? Send us what you dry and how much per run, and we will propose the model.
Benchtop drying oven with fan, LED controller and timer
In the DRYSC benchtop drying oven, the fan moves hot air horizontally across the shelves, so loads dry faster and more evenly than in an oven with natural convection. The housing is low and wide: it fits on a laboratory bench and takes wide trays and long glassware. The LED display shows the measured temperature and the setpoint. The timer runs from 0 to 9999 minutes.
Key features
- Temperature RT+10 °C to 250 °C, resolution 0.1 °C
- Forced air circulation with fan, horizontal air flow
- PID controller with LED display and timer 0–9999 min
- Over-temperature sound and light alarm
- Chamber of galvanically protected steel, 2 shelves supplied; stainless steel on request
Suitable for
- Drying glassware, powders, soil, food and other samples
- A benchtop drying oven for drying to constant mass, for example at 105 °C
- Hot-air sterilisation of glass and metal items
- Heat treatment, ageing and curing tests up to 250 °C
Forced air or natural convection?
With a full chamber or items on several shelves, a fan gives a more even temperature and a faster return to the setpoint after the door is opened. A forced air drying oven also dries wet loads faster, because the moist air is carried to the exhaust port.
For light powders that a fan could disturb, an oven with natural convection is the better choice; see the laboratory drying ovens overview .

Operating functions
PID controller with LED display
The PID controller holds the set temperature and corrects itself by self-tuning. Settings are kept after a power cut, and the parameters can be locked.
Timer and protection
Set the timer from 0 to 9999 minutes; the oven stops heating at the end of the set time. Over-temperature protection is built in. Do not dry flammable, explosive or solvent-containing materials.
Sizes
The benchtop drying oven is available in four chamber sizes, 43, 71, 136 and 225 L, with the same functions. Two shelves are supplied with every oven and further shelves can be ordered. Shelf positions are 25 mm apart.
Construction, installation and care
The chamber is galvanically protected steel and the housing is powder-coated cold-rolled steel. Place the oven level on a bench, with free space around it and above the exhaust port, and connect it to an earthed socket. Clean it cold, with neutral detergent and a dry cloth; do not use acids or alkalis.

Drying oven series compared
COLO.Science drying ovens differ in air circulation, controller, maximum temperature and size. The DRYSC benchtop drying oven is the low, wide model with a fan, for wide trays and bench work up to 250 °C.
| Series | Air circulation | Controller | Max. temperature | Chamber volume |
|---|---|---|---|---|
| DRYSA18 | natural convection | LED | 300 °C | 18 L |
| DRYSA | natural convection | LED | 300 °C | 30–125 L |
| DRYSB | natural convection | LCD, temperature limiter | 300 °C | 30–125 L |
| DRYSD | forced air | LED | 300 °C | 30–625 L |
| DRYSE | forced air | LCD, adjustable fan, temperature limiter | 300 °C | 30–230 L |
| DRYSC (this page) | forced air, low, wide housing | LED | 250 °C | 43–225 L |
| DRYSCN | natural convection, low, wide housing | LED | 250 °C | 43–225 L |
| DRYBF | forced air | LED | 250–300 °C | 640–3070 L |
Vacuum drying ovens: DRYVA, DRYVE and DRYVH series, 25 to 215 L.
How to choose
- 43–71 L — bench-top ovens for glassware and small sample series.
- 136 L — daily drying in a routine laboratory.
- 225 L — the largest chamber of the series, for larger loads.
- Without fan — the DRYSCN series has the same sizes with natural convection.
- Another controller or a vacuum oven? See the laboratory drying ovens overview .
