About SPEX SAMPLEPREP

SPEX SamplePrep is a manufacturer of laboratory sample preparation equipment, with a product history that includes the ball mills and cryogenic grinders originally developed under the Spex Industries name. The brand's current catalog centers on benchtop and floor-standing mills, homogenizers, and the consumables that support them. 3G Electric supplies SPEX SamplePrep equipment and accessories globally, with the line positioned for laboratories that need reproducible size reduction and mixing of small to moderate sample volumes.

The product families most relevant to technical buyers include cryogenic grinding mills, benchtop homogenizers, and foam vial and tube racks. The cryogenic grinder represented in the line, model 6875A-115, uses dual grinding and cooling chambers with a 100 mL capacity and automated fill, operating at a maximum speed of 15 RPM and accepting feed material up to 10 mm grain size. That combination is intended for heat-sensitive or tough materials that cannot be milled at ambient temperature without degradation or agglomeration. The benchtop homogenizer, model 2010-115, is a 0.5 hp unit with a maximum working volume of 50 mL and a double-locking lid, configured for blending, mixing, and emulsifying small samples. Both are benchtop-mounted and supplied with standard electrical plugs for their specified voltage.

The accessory range covers foam vial and tube racks in several compartment counts: 6-tube, 16-tube, 24-tube, and 48-position formats, with part numbers including 1680, 1681, 1686, 2191, 2196-16-PE, and 2300. These are white foam racks intended to hold glass or plastic vials and tubes upright during storage, processing, and transport. They are consumable bench items rather than instruments, and they are specified by holding capacity and compartment count.

For plant engineers and laboratory managers, the practical selection criteria for this line are sample volume, feed size, target particle size, and whether the material requires cryogenic conditions. The cryogenic mill's 100 mL capacity and 10 mm maximum feed size set the upper bound for batch size and incoming material dimensions. The homogenizer's 50 mL working volume and 0.5 hp motor define its suitable sample range. Electrical configuration is specified by model number, so buyers should confirm the voltage and plug type required for their facility.

3G Electric supports the SPEX SamplePrep line by stocking the instruments and the associated racks, and by providing model-level specifications so buyers can match part numbers to their application. Because the catalog includes both capital equipment and low-cost consumables, orders can combine a mill or homogenizer with the vial racks needed to handle the prepared samples. 3G Electric ships these items globally, and quotes are based on the specific model and configuration requested.

Frequently asked questions

Common questions about SPEX SAMPLEPREP from 3G Electric.

What is the maximum feed size and capacity of the SPEX SamplePrep cryogenic grinder model 6875A-115?

The SPEX SamplePrep cryogenic grinder model 6875A-115 has a 100 mL grinding capacity and accepts a maximum grain size of 10 mm. It operates at a maximum speed of 15 RPM and uses dual grinding and cooling chambers with automated fill. The low speed and cryogenic cooling are intended for materials that are heat-sensitive or difficult to mill at ambient temperature. Buyers should confirm that their feed material falls within the 10 mm maximum grain size before ordering, and should verify the electrical configuration against their facility supply.

What is the working volume and motor rating of the SPEX SamplePrep benchtop homogenizer 2010-115?

The SPEX SamplePrep benchtop homogenizer model 2010-115 is rated at 0.5 hp with a maximum working volume of 50 mL. It is a benchtop-mounted unit with a double-locking lid and a standard plug. It is intended for blending, mixing, and emulsifying small samples in laboratory settings. The 50 mL maximum working volume defines the upper batch size, so applications requiring larger volumes would need a different platform. Confirm the voltage and plug type against your laboratory supply before ordering.

Which SPEX SamplePrep foam vial racks are available, and how many tubes or vials does each hold?

The SPEX SamplePrep foam rack range includes several compartment counts. Model 1686 holds 6 tubes in 6 compartments. Model 2196-16-PE holds 16 tubes in 16 compartments. Models 1680 and 1681 each hold 24 vials or tubes in 24 compartments. Models 2191 and 2300 each hold 48 vials or tubes in 48 compartments. All are white foam construction. Selection is based on the number of samples processed per batch and the vial or tube diameter the rack must accommodate.

What materials are SPEX SamplePrep cryogenic mills suitable for?

SPEX SamplePrep cryogenic mills are intended for size reduction of heat-sensitive or tough materials that are difficult to grind at ambient temperature. The cryogenic cooling embrittles the sample so it fractures rather than smears or degrades. Typical categories include polymers, rubber, and other materials that soften or oxidize under ambient milling. The model 6875A-115 accepts feed up to 10 mm grain size and operates at a maximum of 15 RPM. Suitability depends on the specific material's glass transition behavior and target particle size.

Are SPEX SamplePrep homogenizers and mills benchtop or floor-standing?

The SPEX SamplePrep units in this catalog are benchtop-mounted. The homogenizer model 2010-115 is a benchtop unit with a 0.5 hp motor and 50 mL maximum working volume. The cryogenic grinder model 6875A-115 is also a benchtop configuration with a 100 mL capacity. Benchtop mounting means the equipment is intended for laboratory bench installation rather than a dedicated floor footprint. Buyers should account for bench space, clearance for the double-locking lid on the homogenizer, and access to the grinding and cooling chambers on the mill.

How does 3G Electric supply SPEX SamplePrep equipment and accessories?

3G Electric supplies SPEX SamplePrep instruments and accessories globally. The catalog includes cryogenic grinding mills, benchtop homogenizers, and foam vial and tube racks in multiple compartment counts. Orders can combine capital equipment with the consumable racks needed for sample handling. Quotes are based on the specific model number and configuration, so buyers should provide the part number, required voltage, and plug type. 3G Electric provides model-level specifications to help match part numbers to the application.
