Support with Ø8MM Clamps

Quick Answer: The Support with Ø8MM Clamps is a straight tube-holder bar, pictured with a row of small spring clips along its length; the title gives the clamp size as Ø8 mm, so it is meant for narrow tubes of about that outside diameter in agitator set-ups.

Reading the Title

Support is used here in the sense of a holder, and the photo matches it: a long, narrow bar with small clips spaced evenly along one face. Ø is the diameter symbol, so Ø8 mm clamps are clips sized for an 8 mm diameter. For tube holders that usually means the outside diameter of the tube the clip grips; the listing does not say so directly, so it is worth checking against the tubes you plan to use.

An 8 mm diameter is narrow compared with common laboratory tubes: a standard 1.5 mL microtube and a 15 mL conical tube are both wider. Measuring your tubes’ outside diameter with calipers before ordering avoids clips that are too loose to hold or too tight to load.

The bar is listed among rotator and agitator accessories, where holders of this kind mount on the drive so that a row of tubes turns together. Which drive or frame it fits is not stated in the title and should be agreed with the order; the Vertical Support Plate and support rods for rotary shaker discs are related holders in the same range.

Specifications

Typical Uses

• Holding a row of narrow tubes on a rotator or agitator so they turn together
• Mixing small-volume samples in narrow tubes without using a full disc
• Keeping a set of narrow tubes lined up in order during a timed incubation

Care & Handling

• Push tubes straight into the clips and check that each one is gripped along its length.
• Wipe the bar and clips with mild detergent or 70% ethanol, then dry.
• Replace the holder if clips crack or stop gripping.

Why Choose LabEquip

Labs that work with narrow tubes buy a clip bar sized for them rather than forcing tubes into wider clips. Related holders sit in General Lab Products; send your tube dimensions through the contact page to confirm the fit.

Frequently Asked Questions

What does Ø8 mm mean in the product name?

Ø is the diameter symbol, so the clamps are sized for 8 mm. For a tube holder this normally refers to the outside diameter of the tube the clip grips; measure your tubes to be sure.

Will standard microtubes fit the clips?

Unlikely. A standard 1.5 mL microtube is wider than 8 mm, and conical tubes are much wider. Holders made for those tubes are the better choice.

How is a tube’s diameter measured?

Use vernier or digital calipers across the widest part of the tube body below the cap, and measure several tubes from the same batch, since moulded tubes vary slightly.

What does the bar attach to?

It is listed with rotator and agitator accessories, but the title does not name the drive. Give the model of your rotator or frame so the mounting can be matched to it.

Can glass tubes be held in the clips?

Yes, if the diameter matches, but glass does not flex like plastic. Insert glass tubes gently and check that the clip holds them without excessive force, which could crack the glass.

How are the clips cleaned?

Wipe the bar and clips with a mild detergent or 70% ethanol, rinse and dry. Avoid bending the clips while cleaning, as this loosens their grip.
