Stirrers Manufacturer, Suppliers and Exporter in India

Jlabexport is a leading Stirrers Manufacturer,and suppliers in India

Stirrers in this category are the mechanical stirring components used with an external stirrer drive: stirrer shafts in anchor, paddle and link blade forms, together with the glands, replacement sleeves and guides that locate and seal a rotating shaft where it enters a jointed glass vessel. Jlab Export manufactures and exports these components from Ambala, India, for school, university, TVET, research and industrial laboratories.

The range is listed by shaft diameter, shaft length and extended blade length, and the fittings are listed by the shaft diameter they suit together with their cone, socket or thread size. Selection is therefore a fit question first: shaft dimensions must match the vessel, and the gland or guide must match both the shaft and the vessel joint.

This category does not list magnetic stirrers, hotplate stirrers, overhead stirrer motors, vortex mixers or shakers. Motor speed, torque, materials of construction and drive compatibility are not published here and are available on request.

What is included in the Stirrers category?

The category lists seven items: four stirrer shafts (anchor, collapsible paddle, fixed paddle and link), one stirrer gland with ground sleeve, one replacement sleeve with screw cap, and stirrer guides. Product codes run JL-S-1687 to JL-S-1693.

The four shaft types differ in blade form and in the shaft lengths and extended blade lengths offered. The three remaining items are the fittings that carry the shaft: the gland and its replacement sleeve seal the shaft at the vessel entry, while the guide locates the shaft and connects to the vessel through a ground joint.

Individual product pages carry the dimension tables reproduced below. No material specification, temperature rating, speed rating or pack quantity is published at product level.

How do you choose a stirrer shaft for a laboratory vessel?

Choose a stirrer shaft by fixing three dimensions in order: shaft diameter, shaft length and extended blade length. Shaft diameter determines which gland and guide will fit. Shaft length must suit the depth of the vessel and the height of the drive above it. Blade length determines the swept width inside the vessel.

Two shaft diameters are listed across the range: 6 mm and 11 mm. The 6 mm shafts are offered in 450 mm and 600 mm lengths; the 11 mm shafts are offered at 750 mm. Extended blade lengths range from 50 mm on the shortest fixed paddle to 195 mm on the 450 mm anchor.

Confirm the internal diameter and depth of the intended vessel before ordering, because the published data gives shaft and blade dimensions but no maximum vessel size or clearance figure.

What does a stirrer gland do, and how is it sized?

A stirrer gland seals and supports the shaft where it passes into a closed glass assembly, so the vessel can be stirred while remaining closed. The listed Stirrer Gland, Ground Sleeve suits a 6 mm shaft, has a B19 cone and a size 14 thread.

The Replacement Sleeve With Screw Cap is the wear part for that gland. It is also listed for a 6 mm shaft with a size 14 thread, and is ordered separately when the original sleeve is replaced rather than the whole gland.

Only one gland size is published. Buyers running 11 mm shafts, or vessels with a joint other than B19, should confirm availability before specifying, as no alternative gland size appears in the listed range.

What are stirrer guides, and how are they specified?

Stirrer guides locate the rotating shaft and connect the assembly to the vessel joint. They are specified by four figures: stem length, the shaft diameter they fit, socket size and cone size. Two versions are listed.

The 250 mm guide fits a 6 mm shaft and is listed with a B19 socket and a B9 cone. The 350 mm guide fits an 11 mm shaft with a B24 socket and a B24 cone. The socket accepts the mating cone from the vessel or adjacent glassware, so both figures must be checked against the assembly being built.

Guide stem length should be checked against the distance between the drive and the vessel neck, since it is not interchangeable with shaft length.

Which components are available for 11 mm shafts?

For 11 mm shafts the listed range covers the anchor stirrer (750 mm shaft, 140 mm blade), the fixed paddle stirrer (750 mm shaft, 80 mm blade) and the 350 mm stirrer guide. No gland and no replacement sleeve is listed for an 11 mm shaft.

This matters for closed-vessel work. A laboratory intending to stir a sealed or jointed assembly on an 11 mm shaft should confirm with Jlab Export whether a matching gland is available to order, or whether the assembly must be built around a guide alone.

The 6 mm shaft range is more complete: four blade forms, a gland, a replacement sleeve and a guide are all listed.

What should a school, TVET or research laboratory specify when enquiring?

Send the shaft diameter, shaft length, blade form and extended blade length for each shaft required, plus the joint sizes of the vessels the assembly must fit. For glands and guides, state the shaft diameter and the cone or socket size needed at the vessel.

Because materials of construction, temperature limits, speed limits and pack quantities are not published in this category, include those requirements in the enquiry rather than assuming them. Where the stirrer forms part of a wider glass assembly, list the vessel, condenser, adapter and closure alongside it so compatibility is checked as one system.

For tender and bulk orders, supply the full bill of quantities, the destination, packing and marking requirements, and any documents the tender makes mandatory.

Frequently asked questions

What is a stirrer shaft used for in a laboratory?

A stirrer shaft transmits rotation from an external drive to a blade inside a vessel, so liquids can be mixed, suspended or kept homogeneous during preparation and reaction work. The shaft is selected by diameter, length and blade form. Jlab Export lists anchor, collapsible paddle, fixed paddle and link blade forms.

Does this category include magnetic stirrers or hotplate stirrers?

No. This category lists stirrer shafts, a stirrer gland, a replacement sleeve and stirrer guides only. Magnetic stirrers, hotplate stirrers, overhead stirrer drives, vortex mixers and shakers are not listed here. Buyers needing a drive unit should raise a separate enquiry so the correct equipment is quoted.

What shaft diameters and lengths are available?

Two diameters are listed. The 6 mm shafts are available at 450 mm and 600 mm; the 11 mm shafts are available at 750 mm. Extended blade lengths run from 50 mm to 195 mm depending on blade form and shaft length. Other sizes are not published and should be confirmed by enquiry.

What is the difference between a stirrer gland and a stirrer guide?

A gland seals and supports the shaft where it enters a closed vessel; a guide locates the shaft and connects to the vessel through a ground joint. The listed gland suits a 6 mm shaft with a B19 cone and size 14 thread. Guides are listed at 250 mm and 350 mm stem lengths.

Is a gland available for the 11 mm shafts?

No gland or replacement sleeve is listed for an 11 mm shaft in this category. Only the 350 mm stirrer guide is listed for that diameter. Laboratories building a sealed assembly on an 11 mm shaft should confirm gland availability with Jlab Export before finalising the specification.

What material are the stirrers made from?

The material of construction is not stated on the category or product pages. Buyers should request the material specification, along with any temperature or chemical-compatibility limits, for the exact item being quoted. Specifications are available on request.
