Sampling Spear - Custom orders


Grain sampling spear is designed for obtaining a correct and representative sample from bags, cars, trucks, wagons and so on. A sampling should be done in six and more places. Our spears comply with international standards.

We manufacture probes with lengths range from 0.6 m (24″) to 3 m (118″); diameters 25 mm, 35 mm and 50 mm.  We produced probes of 4.5 long (14,76 ft) and diameter  35mm and 50mm for our specific customer, it was geared to sampling grain from rail cars.

They are manufactured in double tube probe with sequential straight or spiral openings from the bottom to the top. When rotating the handle at the top of probe, the openings open successfully, allowing gradual filling of the probe. The probe itself is made of anodized aluminum alloy 6063 with pre-installed improved plastic tip or coned metal.

Main Applications

The probe can be used for all applications where samples need to be pulled from grain bins, trucks, wagons, etc…

With the aid of hand grip, you can easily apply pressure by limiting damages on the probe. It can also be switched from a spear to another. We fix the hand grip onto the probe from its bottom and according the probe dimension because there are two hand grip dimensions, 35mm and 50mm.

There are two types of tips: Plastic improved and coned metal. The plastic tip can withstand a temperature range from -30 to +70°C and is made of low-pressure high density HDPE polyethylene. The plastic tip is comfortable and easy to use when the pile of grain stayed for longtime while transporting or when becomes dense. It is cheap and can be easily changed on the probe. The metal tip is the common tip used traditionally and can be used for the lifetime of the device.

For a secured shipping of the sampling spear, we use brown cardboard tube so that the spear cannot undergo any damages.
