The Yamato DG-440C is a 92 L natural-convection glassware drying oven built specifically for drying and storing washed labware. It combines a stainless-steel chamber, a germicidal (sterilization) lamp, an air-intake filter, and an axial-flow forced-exhaust fan so rinsed glassware dries quickly and stays contaminant-free until you need it. This is the 115V unit; the 220V sibling is the DG450C.

Application Profile
Glassware drying is a distinct job from general lab heating: the goal is to move moisture off clean surfaces fast, without re-depositing airborne particulate. The Yamato DG-440C answers that with a built-in 8 W germicidal lamp and a filtered intake / forced-exhaust path that flushes humid air out of the 92 L chamber while keeping incoming air clean. Rinsed beakers, flasks, and pipettes come out dry and ready to store — the oven doubles as a clean holding cabinet after drying.
Because it runs by natural convection with an assisting exhaust fan rather than aggressive forced circulation, the DG-440C is gentle enough for delicate volumetric glassware while its RT +5 to 70 °C range and 1.0 kW heater keep drying cycles short. A large observation window, stainless interior, and bottom water-receiving plate make it easy to load, watch, and clean.
Frequently Asked Questions
What temperature range does the Yamato DG-440C reach? It operates from room temperature +5 °C up to 70 °C — the correct band for drying glassware without thermally stressing it.
Does it really sterilize glassware? It carries an 8 W germicidal UV lamp and a filtered-intake / forced-exhaust system so labware dries in a hygienic, low-particulate environment. It is a drying/UV-hygiene oven, not a validated autoclave.
How much glassware fits? The chamber is 92 L (450 × 450 × 450 mm) with two stainless shelves rated 15 kg each, adjustable over 10 steps.
Which voltage is this and what is the 220V option? This is the 115V DG440C. For 220V supply, order the DG450C.
Is a floor stand available? Yes — the larger DG800-series shelf & bracket accessory (part 211854) and optional stands extend the family; confirm the correct accessory for your unit at quote.
Ordering & Configuration
Confirm at quote: supply voltage (115V vs 220V DG450C), bench vs stand mounting, and shelf count.
Warranty: Per Yamato standard capital-equipment terms — confirm coverage at quote.
Add the DG-440C to a quote to lock voltage and lead time; it ships with two stainless shelves, brackets, and the water-receiving plate.
