operating temperature range of the DX302C oven?\u003c\/h3\u003e\u003cp\u003eThe DX302C operates from ambient +5 to 300°C. This range supports moisture removal, curing, and constant-temperature holds in a single unit.\u003c\/p\u003e\n\u003ch3\u003eWhat is the chamber capacity and overall size?\u003c\/h3\u003e\u003cp\u003eChamber capacity is 28 liters. The oven measures 36 × 36 × 35 inches and weighs approximately 130 lbs, so confirm bench or floor clearance before installation.\u003c\/p\u003e\n\u003ch3\u003eWhat is the difference between the DX302C and DX312C?\u003c\/h3\u003e\u003cp\u003eVoltage is the only difference. The DX302C runs on 115V and the DX312C runs on 220V; capacity, temperature range, controls, and construction are identical.\u003c\/p\u003e\n\u003ch3\u003eWhat materials are used in the oven construction?\u003c\/h3\u003e\u003cp\u003eThe interior is stainless steel for corrosion resistance, and the exterior is SPCC steel plate with powder coating for durability.\u003c\/p\u003e\n\u003ch3\u003eDoes this oven use a fan for air circulation?\u003c\/h3\u003e\u003cp\u003eNo, it uses natural gravity convection. Fan-free airflow keeps lightweight and powdered samples from being displaced during heating.\u003c\/p\u003e\n\u003ch3\u003eHow is temperature controlled and calibrated?\u003c\/h3\u003e\u003cp\u003eA digital PID controller maintains the setpoint, and a built-in calibration offset function lets you align displayed and actual temperature for validated processes.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e\n{\n  \"@context\": \"https:\/\/schema.org\",\n  \"@graph\": [\n    {\n      \"@type\": \"Product\",\n      \"@id\": \"https:\/\/labsupplies.com\/products\/natural-convection-oven-28l-dx-302c#product\",\n      \"name\": \"Yamato DX302C Natural Convection Oven 28L\",\n      \"sku\": \"DX-302C\",\n      \"mpn\": \"DX-302C\",\n      \"brand\": {\n        \"@type\": \"Brand\",\n        \"name\": \"Yamato Scientific\"\n      },\n      \"manufacturer\": {\n        \"@type\": \"Organization\",\n        \"name\": \"Yamato Scientific\"\n      },\n      \"url\": \"https:\/\/labsupplies.com\/products\/natural-convection-oven-28l-dx-302c\",\n      \"dateModified\": \"2026-06-26\",\n      \"offers\": {\n        \"@type\": \"Offer\",\n        \"priceCurrency\": \"USD\",\n        \"price\": \"1955.00\",\n        \"availability\": \"https:\/\/schema.org\/InStock\",\n        \"url\": \"https:\/\/labsupplies.com\/products\/natural-convection-oven-28l-dx-302c\",\n        \"seller\": {\n          \"@type\": \"Organization\",\n          \"name\": \"LabSupplies.com\"\n        }\n      },\n      \"gtin12\": \"797059926237\",\n      \"image\": \"https:\/\/dl.dropboxusercontent.com\/scl\/fo\/02jn6wbbh1yhzaqkcyplw\/h\/DX302C_DX312C.png?rlkey=wtjo5lqeg5sku9a3506qrpssx\",\n      \"description\": \"Yamato DX302C 28L natural convection oven, ambient +5 to 300°C with digital PID control.
