Poker Vibrator
Poker Vibrator (Product Code: SLE/CE/38) is an internal (immersion) vibrator used to compact concrete specimens from the inside in concrete testing, civil engineering and site laboratories. It is a practical alternative to a traditional tamping bar, especially when large numbers of specimens must be compacted, and it is offered in four versions that differ in flexible shaft length and tip diameter. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is a Poker Vibrator Used For?
A poker vibrator compacts concrete by vibrating it from within. The vibrating tip at the end of the flexible shaft is lowered vertically into the concrete in the mould; the vibration makes the mix behave like a fluid, so entrapped air rises and escapes and the particles settle into a dense mass. Compaction is usually judged complete when large bubbles stop appearing and the surface takes on a smooth, glossy look.
Withdraw the tip slowly so the hole it leaves closes behind it, keep it clear of the mould walls and base, and avoid over-vibrating, which can cause segregation. Matching the tip diameter to the size of the moulds and the shaft length to your working position is the main selection decision. For a busy casting bay, it is an efficient addition to engineering lab equipment used for cubes, beams and cylinders.
What to Specify When Ordering
- Which of the four available versions you need, by flexible shaft length and tip diameter.
- The types and sizes of moulds you compact, so a suitable tip diameter can be proposed.
- How many specimens you cast per day, which shows whether one or more vibrators are needed.
- Any moulds or hand-compaction tools you want quoted on the same enquiry.
Supplier
ScienceLab is the trading name of Jain Scientific Equipments Private Limited, Ambala, which supplies this Poker Vibrator to engineering colleges, research centres, construction laboratories, dealers and importers in India and international markets. Because the company handles a wide range of concrete and cement testing equipment, buyers can source vibrators, moulds and tamping tools through one supplier and one quotation.

Frequently Asked Questions
What is a Poker Vibrator used for in a concrete lab?
The Poker Vibrator is used for the internal compaction of concrete specimens. Its vibrating tip is immersed in the fresh concrete inside the mould, driving out entrapped air so that cubes, cylinders or beams are dense and give reliable strength results.
How many versions of the Poker Vibrator are available?
The Poker Vibrator (SLE/CE/38) is available as four products, which differ in flexible shaft length and tip diameter. Tell us the moulds you use and we will confirm the details of each option through the contact page.
Is a poker vibrator better than a tamping bar?
A Poker Vibrator is a good alternative to the traditional tamping bar, particularly when large numbers of specimens need compacting, because it consolidates concrete faster and with less manual effort. For occasional small batches or teaching demonstrations, hand tamping can still be adequate.
How do I avoid over-vibrating concrete?
When using a Poker Vibrator, stop once large air bubbles no longer rise and the surface looks smooth and glossy, then withdraw the tip slowly. Vibrating far beyond this point can drive coarse aggregate down and bring excess paste and water to the top, causing segregation.
Who supplies the Poker Vibrator?
The Poker Vibrator is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, based in Ambala, Haryana, India. The company sources it for colleges, testing laboratories, dealers and importers and can combine it with other concrete test equipment on a single quotation.
What should I include when requesting a quotation?
For the Poker Vibrator, state the version (shaft length and tip diameter) if known, the quantity, the moulds you compact, your organisation name and the delivery location. If you are unsure which version suits you, describe your specimens and we will advise.
