45° Conical Probe – stainless steel

Seven conical perspex/stainless steel probes with penetration angles of 30 – 60 degrees are used for cone penetrometer tests on plastic samples such as waxes, butter, margarine and similar spreads. A cone angle is selected which ensures that the sample displays plastic behaviour during testing. Cone penetrometry correlates well with sensory evaluation and spreadability indices.

Conical probes can be made with different angles to order.

Solid materials which are self-supporting or contained.

• Cone tips are fragile and easily broken.
• During a test if the force increases it is difficult to determine whether the sample is harder or the increased force is due to the increased surface area of the probe. For this reason, more popular penetration tests use cylinder probes.

Stable Micro Systems probes and attachments are commonly made from four materials: anodised aluminium (AA6082 T6), stainless steel (316 T), Delrin (acetyl copolymer) and Perspex (polycarbonate).

In general use, probes and attachments made from these materials will be suitable for testing food products and inert non-food materials.

The four materials listed above are not universally resistant to all types of chemicals and as such the compatibility of the probe/attachment material with the product (to be tested) must be established to prevent damage to the probes and attachments. If the compatibility of the product with the probe is unknown to the customer then the chemical information about the product (Material Safety Data Sheet or Product Data Sheet) should be submitted to Stable Micro Systems. Stable Micro Systems will then assess the suitability of the probe/attachment material for use with the product and advise accordingly. If this advice is not sought then Stable Micro Systems will not accept liability for probes/attachments damaged by chemical attack from the product being tested.

All probes and attachments may be cleaned in warm (or hand hot) water using a mild detergent. A soft brush may be used but abrasive cleaning aids should be avoided. Stable Micro Systems products should not be microwaved or cleaned in a dishwasher.

Screw threads should be lightly lubricated after drying using a light lubricant, e.g. petroleum jelly, mineral oil. This will aid the fitting and unscrewing of the item. Each component of a probe or attachment should be wrapped separately when stored, to avoid scratching or chipping. This will safeguard against any unnecessary damage to the accessory.
