Quick Answer: A scintillation vial rack is a bench rack with round holes sized for scintillation vials, holding them upright while samples and scintillation cocktail are added, capped and labelled. It keeps vials in counting order before they are transferred to the counter’s own cassettes.

Preparing Vials for Liquid Scintillation Counting

Liquid scintillation counting measures low-energy beta emitters such as tritium and carbon-14 by mixing the sample with a scintillation cocktail inside a vial. Before counting, each vial is filled, capped, shaken and labelled, often in batches of dozens. A dedicated rack holds the vials steady through these steps, so a tipped vial does not spread radioactive cocktail across the bench.

Vials come mainly as standard vials of about 20 ml and mini vials of around 6 to 7 ml, and a rack is normally made for one of these diameters. Which vial size this rack takes, and how many positions it has, can be confirmed with the order.

Radioactive work stays inside the area set aside by your radiation safety rules, and the rack becomes part of that area. A tray lined with absorbent paper under the rack catches drips, and the rack should be monitored or wipe-tested after use as your local procedure requires.

Specifications

Holds	Scintillation vials, upright
Vial size and positions	Confirm at enquiry
Material	Not stated in the title
Use	Filling, capping, labelling and short-term storage of vials
Setting	Radioisotope work area, used with a drip tray

Care & Handling

Stand the rack in a spill tray lined with absorbent paper.
Monitor or wipe-test the rack after radioactive work as your radiation safety procedure requires.
Do not let solvent-based cocktail pool on the rack, since some solvents attack plastics.
Label the rack for radioactive use so it is never moved to general work.

Applications

Batch preparation of tritium or carbon-14 samples for counting
Holding cocktail blanks and standards alongside the samples
Keeping vials in order for loading into counter cassettes
Short-term storage of sealed vials awaiting counting or disposal

Why Choose LabEquip

Radiochemistry, biochemistry and pharmacology labs that run liquid scintillation counting need racks that keep vials in order during preparation. LabEquip offers this rack in the Biology Lab Products range alongside scintillation vials; give the vial size on the contact page.

Frequently Asked Questions

Can I put the rack directly into a scintillation counter?

Usually not. Most counters use their own cassettes or racks designed for the instrument’s conveyor. This rack is for bench preparation and storage, after which vials go into the counter’s holders.

Will standard and mini vials fit the same rack?

Normally not, because the holes are sized for one vial diameter. Mini vials are narrower and would sit loosely in holes made for standard 20 ml vials.

How should the rack be cleaned after radioactive work?

Wipe it with a decontamination solution suited to radioisotopes, then monitor or wipe-test it according to your radiation safety procedure. If contamination remains, keep it for radioactive work only or dispose of it as radioactive waste.

Can scintillation cocktail damage the rack?

Solvent-based cocktails containing toluene or xylene can soften or craze some plastics. Wipe drips promptly and prefer safer, biodegradable cocktails where the protocol allows.

Why keep vials in a fixed order in the rack?

Counting results are printed by position, so loading vials in the same order as the sample sheet avoids mix-ups between the rack, the counter cassette and the printout.

Can the rack hold other vials?

Yes, any vial of the same diameter, such as sample or storage vials, will fit. Racks that have been used with radioactivity should stay separate from those used for general work.
