Serenit Electric Bike

Quick Answer: The Serenit electric burner, listed here as the Serenit Electric Bike, is a mains-powered bench heater used in place of a gas Bunsen burner for routine heating. The listing photo shows a spiral heating element set into the top of a moulded base, with a control knob, indicator lamps and an upright support rod at one corner.

What the Serenit Is, and Why the Odd Name

The word ‘Bike’ in this listing is a translation slip. The product line is sold in French as a ‘bec électrique’, and ‘bec’ is the everyday French word for a laboratory burner, as in ‘bec Bunsen’. What is listed here is the Serenit electric burner itself, the base unit that the Serenit rod and grid accessories in this range are named for.

Instead of burning gas, the Serenit heats with an electric element. In the photo the element is a flat spiral coil in a round recess on top of the unit, glowing red when switched on, with the control knob on the front panel and a vertical rod fixed at one corner. That rod gives a place to clamp a test tube, a ring or a thermometer over the heat, much as a retort stand would beside a gas burner.

With no gas line or cartridge, this burner suits rooms that were never plumbed for gas and schools that have removed gas taps from junior labs. It is not cool just because it is flameless: the top of the unit and anything resting on it get very hot, and the heat is harder to see than a blue flame. The Serenit Microbio version is photographed with a broad tray around the element for aseptic work; this listing is the plain model with the corner rod.

Specifications

Applications

• Heating test tubes of water or dilute solutions in lower-secondary practicals held in rooms without gas taps
• Warming a small beaker of liquid with a thermometer clamped to the corner rod
• Evaporating a little salt solution in a dish to show crystals forming as the water leaves
• Supervised heating stations at exams or open days, where loose gas tubing on benches is unwelcome

Care & Handling

• Stand the Serenit burner on a heat-resistant, uncluttered bench, with the power cord routed away from the top of the unit.
• Keep flammable solvents and their vapours away; a glowing element ignites them as readily as a flame does.
• After switching off, leave the unit to cool before moving it or packing it away, because the heating zone stays hot long after the glow fades.
• Wipe spills from the casing only when the burner is cold and unplugged, and never pour liquid onto the element.

Why Choose LabEquip

Schools converting labs away from piped gas, and departments that want a gas-free heating station for younger classes, are the usual buyers of this Serenit unit. LabEquip lists it in chemistry lab equipment alongside the removable support rod and the protection grid named for the same burner, so a complete station can be requested together through the contact page.

Frequently Asked Questions

Why is this burner listed as an ‘Electric Bike’?

It is a translation error. The French name of the product uses ‘bec’, the usual word for a laboratory burner, and it was rendered literally. The item is the Serenit electric burner, a bench heater, and has nothing to do with bicycles.

Can the Serenit do everything a gas Bunsen burner does?

It covers routine heating of test tubes, beakers and dishes. Jobs that rely on a flame itself, such as flame tests for metal ions or comparing a luminous and a roaring flame, cannot be done on an electric heater, so a gas burner is still needed for those lessons.

Is an electric burner safe to use with ethanol or other flammable liquids?

No. The element runs hot enough to ignite flammable vapours, so the absence of a visible flame gives no protection. Warm such liquids in a water bath filled from a kettle, with no heater nearby.

What is the upright rod on the unit for?

The rod acts like a small retort stand fixed to the burner. Boss heads and clamps attached to it can hold a test tube, a thermometer or a small ring over the heating zone, which saves bench space and keeps apparatus centred over the heat.

How long does the burner stay hot after switching off?

Long enough to cause burns, and much longer than a gas flame, which vanishes as soon as the tap is closed. Treat the top of the unit as hot until it has been off for several minutes, and teach students to check for warmth with a hand held above it, never by touch.

What power supply does the Serenit burner need?

It runs from a mains socket, and the listing does not state the voltage or plug type. Tell LabEquip which country the burner will be used in, so that the supply and plug can be matched before dispatch.
