Controlled Low Strength Material Sample Kit (CLSM)

The CLSM Sample Kit is a ready-to-use solution for sampling and testing controlled low strength material (flowable fill), designed to simplify specimen preparation while protecting specimen integrity.

Each cylinder mold features an engineered liner that minimizes friction, allowing specimens to release easily from the mold. A bottom insert reduces vacuum and helps protect specimen edges from damage. Cylinders with lids are packaged in a heavy-duty, partitioned container to safeguard specimens during transport.

• Ready to use – no special tools required
• No cutting or knives needed
• Reduces risk of specimen damage during removal
• Produces consistent, high-quality test specimens

Customer Feedback:

“The ability to slip the samples out was astonishing. It maintained the specimen's integrity… This mold is what I consider a ‘state of the art’ mold for testing flowable fill.”
