Support Rods For Rotary Shaker Discs

Quick Answer: Support rods for rotary shaker discs are metal rods, pictured with threaded ends, that carry circular tube-holder discs on a rotator so the discs stay aligned and evenly spaced while they turn.

The Role of the Rods

When a rotator carries more than one circular tube holder, something has to keep the discs parallel and at the right spacing. The photo shows several bright metal rods with threaded ends, which join the disc holders into a rigid assembly. With the discs held square, each tube sits straight in its clips and the whole assembly turns without wobble.

Rods also let a lab reconfigure its rotator. Moving discs along the rods changes the spacing to suit a different tube length, and adding a disc increases capacity. A bent rod does the opposite: it throws discs out of line, so tubes grip unevenly and the drive is strained.

The title does not state rod length, thread or how many rods come in one order, and these must match the discs and rotator. Circular holders such as the Disc for rotary disc digital shaker and drives like the Rotary mixer STR4 appear in this range; confirm which one the rods are meant for.

When Rods Are Needed

Building a multi-disc rotator assembly for larger batches of tubes
Changing disc spacing to suit longer or shorter tubes
Replacing a bent or damaged rod that makes discs run out of true

Care & Handling

Tighten fixings evenly so discs stay square to the rods.
Roll a rod on a flat bench to check it is straight, and replace it if it rocks.
Wipe rods dry after cleaning so threads stay free and do not corrode.

Frequently Asked Questions

What are the support rods used for?

They carry circular tube-holder discs on a rotator, keeping the discs parallel and evenly spaced so tubes sit straight and the assembly turns smoothly.

How many rods come in one order?

The title does not state a quantity, and the photo shows several rods together. Ask us to confirm the number supplied when you enquire, along with length and thread.

How can I tell whether a rod is bent?

Roll it slowly across a flat bench. A straight rod rolls evenly, while a bent one rocks or lifts at one point. A bent rod should be replaced rather than straightened.

Can the discs be moved along the rods?

Yes, adjusting disc spacing to suit tube length is one reason for using rods. Tighten the fixings evenly afterwards so every disc sits square.

Do the rods need lubrication?

No oil is needed on the rods themselves. Keep threads clean and dry so fixings tighten properly, and avoid grease that could attract dust and contaminate samples.
