Natural Convection Glassware Drying Oven With Sterilization Lamp 92L Overview
The Natural Convection Glassware Drying Oven With Sterilization Lamp 92L (Yamato Scientific DG440C/DG450C) is a 92-liter gravity convection oven engineered for drying and storing laboratory glassware across an operating range of ambient +5 to 70°C. LabSupplies.com supplies it as an authorized Yamato Scientific dealer.
A built-in germicidal lamp, intake-port air filter, and exhaust fan support fast, clean drying. Heat reaches glassware through a stainless steel pipe heater, while a bottom water-receiving plate captures runoff. The SUS304 stainless steel interior resists corrosion and wipes down easily; a large observation window lets technicians monitor loads without opening the door.
Both members share the same 92L chamber and 28 × 31 × 35 in footprint, differing only by voltage: DG440C runs on 115V, DG450C on 220V. Each unit weighs roughly 200 lbs, rests on adjustable feet for uneven floors, and is manufactured under ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 systems. Ships from USA inventory.
Key Features
- 92L natural convection chamber: gravity airflow dries glassware gently across ambient +5 to 70°C.
- Germicidal sterilization lamp: integrated UV lamp supports sanitary drying and post-dry instrument storage.
- Filtered intake and exhaust fan: air-intake filter plus exhaust fan promote fast, clean moisture removal.
- SUS304 stainless interior with water-receiving plate: corrosion-resistant, easy-clean chamber that captures runoff at the bottom.
- Dial setting with digital display: temperature and timer set by dial and shown on a digital readout.
- Adjustable feet and large window: stable leveling on uneven floors and at-a-glance load monitoring.
How to Choose the Right Convection Oven
Selecting a glassware drying oven comes down to matching chamber size, temperature needs, controls, and site power to your workflow. Use the criteria below to confirm the unit fits both your bench plan and your facility.
- Capacity: a 92L chamber holds larger or batched glassware loads; size the chamber to your typical drying volume.
- Temperature range: this oven runs ambient +5 to 70°C, suited to gentle glassware drying rather than high-heat bake-out.
- Control type: dial setting with digital display balances simple operation with readable temperature and timer feedback.
- Voltage: choose DG440C for 115V circuits or DG450C for 220V to match your lab's available power.
- Footprint and weight: confirm the 28 × 31 × 35 in dimensions and ~200 lb weight suit your bench or floor space.
- Drying hygiene: the germicidal lamp, intake filter, and exhaust fan matter when clean, sanitary storage follows drying.

Frequently Asked Questions
What is the operating temperature range of the DG440C oven?
The DG440C operates from ambient +5 to 70°C. This gentle range suits glassware drying and post-dry instrument storage rather than high-temperature bake-out applications.
What is the chamber capacity and overall size?
The chamber capacity is 92 liters. External dimensions are 28 × 31 × 35 inches (L × W × H), and the unit weighs approximately 200 lbs, so confirm bench or floor clearance before ordering.
What is the difference between the DG440C and DG450C?
Voltage is the only difference. The DG440C runs on 115V and the DG450C on 220V; both share the same 92L chamber, temperature range, materials, and footprint.
What materials are used in the oven construction?
The interior is SUS304 stainless steel for corrosion resistance and easy cleaning. The exterior is bonderized steel sheet iron with a melamine resin baking finish.
