Laboratory Stirrer Manufacturer,Supplier and Exporter in India

Product Code : EL-RE-2084
Jlab Export is a leading Laboratory Stirrer Manufacturer,and suppliers in India

An overhead laboratory stirrer drives a stainless steel shaft and blades down into the vessel from a motor mounted above it. It can keep thick mixtures moving where a magnetic bar would stall. This one stands on a heavy cast iron base with a chrome-plated mild steel upright rod. The 1/20 HP AC/DC motor has variable speed and a 0–60 minute automatic timer.

Pharmaceutics and Chemistry Practicals

Pharmaceutics students prepare emulsions and creams with it. They melt the oil phase and warm the water phase in a Water Bath Rectangular, then stir the two together in one of the Tall Form Beakers, Borosilicate Glass, Economy while the mix cools and thickens. The finished cream is worked and filled with an SS Ointment Spatula.

For a suspension practical, students disperse a powder in a suspending agent at a set speed and time. They pour each batch into Glass Foot Measuring Cylinders Hexagonal Base Borosilicate Glass Class B JLab and read the sedimentation volume each day. Repeating the formula at two speeds shows how mixing changes the result.

Frequently Asked Questions

When should I use an overhead stirrer instead of a magnetic one?
Use it for creams, pastes, slurries and large batches, where a magnetic bar stalls or loses grip. The motor drives the shaft directly, so the blades keep turning through viscous material. Thin solutions in small beakers are easier on a magnetic stirrer.

How do I set the blades in the vessel?
Move the stirrer on the upright rod until the blades sit close to the bottom without touching it, and keep the shaft clear of the vessel wall. Hold the vessel firmly so it cannot turn with the blades. Start at low speed and raise it gradually.

What does the 0–60 minute timer do?
It switches the stirring off automatically when the set time ends. That suits methods with a fixed mixing time, and a batch is not left running after the class has moved on.

Why does my cream splash or fill with air bubbles?
The speed is too high for the volume, or the blades sit too close to the surface and pull air in. Lower the speed, set the blades deeper and use a vessel wide enough for the blade sweep.
