Static rod for magnetic stirring hotplates

Quick Answer: The Static Rod for Magnetic Stirring Hotplates is a fixed, upright support rod that fits a hotplate stirrer so that a probe, condenser or small clamp can be held over the stirred vessel. The listing photograph shows a long steel rod with a threaded end, a black boss clamp and a shorter cross-arm with a holder.

What the Rod Kit Includes, Going by the Photo

“Static” here means the rod does not move once fitted; it is the fixed upright of a small stand built onto the stirrer rather than a separate retort stand. The photographed set has three parts: a long stainless-looking rod with a short threaded end, a black right-angle boss clamp, and a shorter horizontal rod ending in a black holder. The threaded end suggests the rod screws into a socket on the hotplate stirrer, which many models provide at the back or side of the housing.

With the boss clamp on the upright and the short arm across, the holder can be swung over the vessel and set at any height. That arrangement is typically used for a temperature probe that controls the stirrer’s heating, but the same arm can hold a thermometer or a small electrode.

Rod thread and diameter vary between stirrer brands, so the rod will only screw into a hotplate with the matching socket. The listing does not name the compatible models, and that is the key point to confirm.

What the Rod Is Used For

• Holding a temperature probe in a beaker or flask so the stirrer can control the liquid temperature
• Positioning a thermometer during a heating curve or boiling-point practical
• Holding a pH or conductivity electrode in a stirred solution
• Supporting a Pt1000 clamping system for probe-controlled heating

Specifications

Care & Handling

• Screw the rod in by hand until firm; overtightening can damage the housing socket
• Keep the probe clear of the stir bar and the vessel wall
• Do not hang heavy glassware on the cross-arm; use a full retort stand for condensers and large flasks
• Wipe the rod after spills, as residues can make the boss clamp slip

Why Choose LabEquip

Labs buy this rod when they add an external temperature probe to a hotplate stirrer and need a neat way to hold it. LabEquip can check that the thread matches your stirrer and supply the rod with a probe and clamp from our general lab products range. Contact us with your stirrer model.

Frequently Asked Questions

What does static mean in the name of this rod?

It means the rod is a fixed upright that stays in one position once fitted to the hotplate stirrer, unlike a rotating or swinging arm on some stands.

How does the rod attach to a hotplate stirrer?

The photographed rod has a threaded end, which normally screws into a threaded socket on the stirrer housing. Check that your stirrer has a matching socket before ordering.

Can I hold a condenser on this rod?

A short reflux condenser on a small flask may be held with a suitable clamp, but heavy glassware is safer on a full retort stand with a wide base.

Why is the probe position important?

The probe controls the heating. If it sits against the glass, touches the stir bar or lifts out of the liquid, the reading is wrong and the plate can overheat the sample.

How is this rod different from the SR1 static stem?

Both are fixed support rods for stirrers. This listing shows the rod with a boss clamp and a cross-arm, while the SR1 stem is sold under its own model code. Thread and fit differ by stirrer brand.

What should I check before ordering?

Check your stirrer’s make and model and whether it has a rod socket. Send those details through the contact page and we will confirm that the thread matches.
