Hot plates & heating blocks

A hot plate heats beakers, flasks with a flat base and other vessels that stand on it. A dry heating block holds tubes and vials in drilled holes, so every tube gets the same contact and temperature, without a water bath, as with the mini block heater. If you also need to stir, choose a heated stirrer from magnetic stirrers. For round-bottom flasks, a plate gives poor contact; use a mantle from heating mantles instead. Tell us your vessels and we will suggest the right device: sales@luminixhealth.com.

Each material has its strengths. Glass ceramic resists many chemicals and is easy to clean; aluminium spreads heat quickly and evenly; titanium suits high temperatures and aggressive conditions, as with the high-temperature titanium hotplate; stainless steel is robust for routine use. Check chemical resistance, cleaning advice and maximum temperature on each product page, rather than relying on general rules. Also match the plate size to the number of vessels you heat at once. Other heaters are in heating mantles. Unsure? Ask sales@luminixhealth.com.

The block must match the hole diameter and volume of your tubes: 0.2 ml PCR tubes, 1.5 ml tubes, 15 ml and 50 ml tubes each need their own block, and the product title states the format. Tubes that sit loosely heat slowly and unevenly. Many devices take interchangeable blocks, such as the dry block heater for 4 blocks, but blocks only fit the device they are made for; check compatibility on the product page. Tubes are in microcentrifuge and reaction tubes. Send us your device and tube type: sales@luminixhealth.com.

Analogue control with a dial is simple and robust for routine heating where the exact value matters less. Digital control lets you set and repeat a temperature exactly, and often adds a timer, as with the heating block with dual control. An external probe measures in the liquid itself and lets the device regulate on the medium rather than the plate, which avoids overshoot and gives the temperature your method requires. Check on the product page whether a probe can be connected; probes are in temperature probes and sensors. Questions? Ask sales@luminixhealth.com.

A hot plate heats a flat-bottom vessel from below, often with stirring. A heating block holds tubes in machined holes so each tube sees the same temperature. The block's hole diameter has to match the tube, or the heat never arrives.

Temperature equipment either holds a set point or drives a sample toward one. An oven dries. A furnace reaches the temperatures of ashing and melting. A bath surrounds a vessel with water or oil. A circulator moves that fluid. An incubator holds the mild warmth of a culture. An autoclave uses steam under pressure to sterilise. The number that matters is the temperature the article actually reaches, not the number painted on the dial. Temperature is part of the international system kept by the BIPM and compared by EURAMET.
