LCD Magnetic Heating Stirrer Pack – DLAB

Quick Answer: The LCD Magnetic Heating Stirrer Pack from DLAB is a hotplate magnetic stirrer with an LCD display, sold as a pack; the product photo shows it with a support rod and an external temperature probe held in a clamp above the plate, ready to control the temperature of the liquid.

What the Pack Combines

A magnetic heating stirrer does two jobs in one footprint. A rotating magnet under the top plate turns a PTFE-coated stir bar inside the vessel, while a heating element warms the plate. This laboratory magnetic stirrer design keeps a solution moving as it heats, so temperature evens out and solids dissolve faster than they would in an unstirred beaker.

The LCD readout shows the settings as numbers rather than leaving the user to judge a knob position, which helps when a method specifies a stirring speed or temperature. The photo also shows an upright support rod with a clamped probe reaching towards the vessel. With an external probe in the liquid, a stirrer of this kind can regulate the plate from the solution’s own temperature, avoiding the overshoot that occurs when only the plate is controlled.

DLAB, named in the title, is a laboratory instrument brand. The title does not state what the pack contains or the stirrer’s plate size, speed range and maximum temperature, so those details should be confirmed with the order.

Everyday Jobs for a Heating Stirrer

• Dissolving solids for standard solutions, warming to speed dissolution and cooling before making up to volume
• Melting and mixing agar or gelatin media so they set evenly
• Stirring a titration flask while titrant is added, with the heater switched off
• Holding a solution at a set temperature under probe control during a kinetics or recrystallisation practical

Safe Use & Care

• Put the probe into the liquid before selecting probe control; a probe left in air makes the plate keep heating.
• Never heat flammable solvents on an open hotplate; use a closed, suitably controlled set-up instead.
• Start stirring slowly and raise the speed gradually so the bar stays coupled to the magnet.
• Keep the mains cable clear of the hot plate and wipe spills only after the plate has cooled.

Why Choose LabEquip

Chemistry departments, teaching labs and quality-control benches buy a heating stirrer pack when they want the stirrer, stand and probe to arrive as a working set. For round-bottomed flasks, pair it with the Thermal adapter 500 mL or a heating block for flasks; more bench equipment is in General Lab Products.

Frequently Asked Questions

What does the external temperature probe add?

It lets the stirrer control the temperature of the liquid itself instead of the plate. The controller reads the probe and adjusts heating to hold the solution at the set value, which gives steadier results and less overshoot.

Why must the probe be in the liquid before heating starts?

Under probe control the stirrer heats until the probe reaches the set point. A probe left in air, or lifted out during a run, reads low, so the plate keeps heating and can overheat the vessel.

Why does the stir bar jump or spin off-centre?

It has lost coupling with the magnet, usually because the speed was raised too quickly, the bar is too long for the vessel, the vessel base is uneven or the liquid is viscous. Stop, let the bar settle, then restart at a lower speed.

Which stir bar should be used?

Use a PTFE-coated bar roughly a third to half the width of the vessel base. Oval bars suit round-bottomed flasks, while cylindrical bars suit flat-based beakers and bottles.

Can flammable solvents be heated on this stirrer?

Not on an open hotplate. A hot plate surface can ignite solvent vapour, so flammable liquids should be heated in a closed system with appropriate controls, normally in a fume hood, following your lab’s risk assessment.

What does Pack mean in the product name?

It indicates the stirrer is sold as a set rather than as a bare unit; the photo shows it with a support rod, clamp and temperature probe. Contents can vary by order, so ask for the included items to be confirmed when you enquire.
