The Yamato DG-400C is a 92-liter natural-convection glassware drying oven built for gentle, air-current-free drying of washed labware. Because it moves heat by natural convection rather than a fan, the DG-400C dries lightweight glassware, filters, and delicate parts without blowing them around the chamber, then doubles as a clean, warm cabinet for storing instruments afterward. A stainless-steel interior and a bottom water-receiving plate handle the runoff and corrosion that glassware drying throws at an oven.

Application Profile
Natural convection is the right mode for a glassware drying oven: with no fan, nothing disturbs rinse water or lightweight labware. The DG-400C holds a deliberately moderate RT +5 to 70 °C (the job is evaporating water off clean glass, not high-temperature processing) while the stainless-steel chamber resists the moisture and detergent residue that would corrode a painted interior. The 92 L chamber takes two shelves, a 3 mm window lets you check progress, and a bottom water-receiving plate catches drips from inverted glassware; the same insulated cabinet then keeps clean instruments dust-free and warm. Yamato notes reduced accuracy with heat-generating samples inside (a drying and storage oven, not a reaction chamber) and it is not explosion-proof, so never load flammable material.
Frequently Asked Questions
How many shelves and how much can each hold? The DG-400C accepts 2 shelf plates on 4 brackets, with 10 rest positions at 30 mm pitch and a 15 kg load rating per plate. Shelf-and-bracket sets are an optional add-on (Yamato code 212246).
Does it include a germicidal lamp or air-intake filter? No. Those belong to the DG440C/450C forced-convection models. The DG-400C is the plain natural-convection version with dual passive exhaust (I.D. 34 mm × 2) and suction ports (I.D. 30 mm × 2).
What voltage does it ship as? This SKU is configured for 115 V. The DG400C/410C column is rated AC115V / AC220V, so confirm the exact supply voltage at order.
Ordering & Configuration
Confirm at quote: supply voltage (115 V vs 220 V), shelf-and-bracket sets, and optional stand or seismic mat. Warranty: per Yamato standard capital-equipment terms. Confirm coverage at quote. Add the Yamato DG-400C to a quote to lock voltage, shelving, and lead time.
Choosing within the DG line: DG-440C/450C add a germicidal lamp, air-intake filter, and forced-exhaust fan to the same 92 L body; DG-800C/850C scale to 445 L floor-standing. Pick the DG-400C for simple, gentle bench drying and warm storage without UV or forced airflow.
