The Yamato DG-850C is the 445 L natural/forced-convection glassware drying oven at the top of the DG-series line, built for high-throughput labs that wash and dry glassware in volume. It pairs PID-controlled convection drying with an 8 W-class germicidal (sterilization) lamp, an air-intake filter and axial-flow forced exhaust for fast, hygienic turnaround, and it rolls on casters so a 445 L floor-standing chamber can be repositioned without a crane. This is the 220V build; the 115V sibling is the DG840C.

Application Profile
Glassware drying is deceptively demanding: a rinse-wet flask carries a film of water that must be driven off uniformly and without redepositing airborne dust or microbial load before the vessel goes back into service. The DG-850C answers both needs at once. Forced convection with a filtered air intake and forced exhaust pulls moisture out of the 445 L chamber quickly, while the germicidal lamp suppresses biological contamination on the clean glass, a meaningful advantage over a plain drying cabinet in microbiology, cell-culture and QC labs. Because these models combine natural and forced modes, gentler natural convection is available for heat-sensitive labware.
The chamber is stainless-steel lined with a bottom water-receiving plate, and 29 shelf positions let a lab stage large batches of beakers, flasks and cylinders. As Yamato notes, accurate temperature control may not be achievable with strongly heat-generating samples in the chamber. This is a drying and low-temperature (≤70 °C) storage oven, not a high-temperature process oven. For sterilization or curing above 70 °C, step up to a Yamato DKN/DX forced-convection oven.
Frequently Asked Questions
What is the maximum temperature of the DG-850C? The DG-series operates from room temperature +5 °C up to 70 °C. It is a glassware drying oven, not a high-temperature process oven.
What does the sterilization lamp do? The 15 W germicidal lamp (fitted on DG440C/450C/840C/850C) reduces microbial load on the drying glassware, so vessels come out clean and hygienic, useful in microbiology and cell-culture workflows.
How large is the chamber? 445 L: internal dimensions 620 × 600 × 1195 mm, with four stainless shelves (15 kg each) across 29 shelf positions.
Is it forced or natural convection? Both. DG840C/850C are natural / forced convection with an axial-flow forced-exhaust fan and a filtered air intake for fast drying.
What voltage does the DG-850C use? The DG-850C is the 220V build; order the DG840C for a 115V supply. Both are the same 445 L forced-convection oven with germicidal lamp.
Can it be moved once installed? Yes. The 800/810/840/850 large-capacity units are mobile on casters, with an adjustable foot for stability on uneven floors.
Ordering & Configuration
Confirm at quote: supply voltage (this SKU is 220V), floor clearance for the 674 × 711 × 1618 mm cabinet, and whether you need the optional shelf & bracket set (211854), seismic mat, or a stand.
Warranty: Per Yamato standard capital-equipment terms. Confirm coverage at quote.
Add the Yamato DG-850C to a quote to lock voltage, accessories and lead time.
Positioning: the DG-850C is the largest, hygiene-focused glassware dryer in the DG line, 445 L, forced convection, germicidal lamp, mobile on casters. Choose it over a passive drying cabinet when throughput and contamination control both matter; choose the 92 L DG440C/450C when bench-scale volume is enough, or a DKN/DX oven when you need process temperatures above 70 °C.
