Shaking Machine (Wrist Action) Manufacturer,Supplier and Exporter in India

Product Code : EL-S-2073
Jlab Export is a leading Shaking Machine (Wrist Action) Manufacturer,and suppliers in India

A wrist-action shaker copies the flick of a hand shaking a flask. This machine has a heavy cast-iron base and two side arms that carry holders for 100 to 1000 ml flasks, in 4-flask or 12-flask models. A heavy-duty fractional motor with a continuously variable controller gives 80 to 280 oscillations per minute.

Extraction Practicals for Chemistry and Pharmacy Students

In the distribution law practical, students shake iodine with water and an organic solvent in stoppered flasks until the iodine has shared itself between the two layers. The layers are parted in a Separating Funnel, and each is titrated from a Burette, Borosilicate Glass, with PTFE Stopcock to find the distribution coefficient.

Pharmacognosy students macerate a powdered crude drug with a solvent in a Conical Flask. The machine replaces the repeated hand shaking a maceration needs. Every flask gets the same treatment, so extract yields from different groups can be compared.

Frequently Asked Questions

What is wrist-action shaking?
The holders swing through a short arc, like a wrist flicking a flask, so the liquid is thrown against the walls and mixed hard. It is stronger than a gentle swirl and suits extractions and the mixing of two liquid layers.

What flask sizes fit the holders?
The holders take flasks from 100 to 1000 ml. The 4-flask model suits small batches and teaching demonstrations, and the 12-flask model lets a whole group run its samples at the same time.

What speed should I set?
Start near the low end of the 80 to 280 oscillations per minute range. Raise the speed until both layers mix fully without liquid reaching the stopper. Very fast shaking of some solvent mixtures forms emulsions that are slow to separate.

Does it come ready to plug in?
Yes. It is supplied complete with cord and plug for a 220 V AC, 50 Hz single-phase supply. An automatic 0–60 minute timer is available as an option to end each run on time.

Why does it have a heavy cast-iron base?
The weight keeps the machine steady on the bench while the arms swing loaded flasks. A light base would rock or creep across the bench, especially with every holder filled.
