Need a customised solution?
Optional accessories are available for purchase separately. If your order needs a customised configuration, our technical specialists will follow up with full details before your order is finalised. Contact us via the enquiry form or sales@lasec.com.
Installation, training and special delivery
Some products require installation, training, or special delivery (such as tail-lift trucks, extra labour, or hazardous material packaging). If your order needs this, we'll contact you with the additional cost before dispatch, so your final invoice may differ from the listed price.

Product Overview
- The CISA 450 mm Ø x 100 mm H test sieve is designed for particle-size testing and coarse-particle separation. The AISI-316 stainless steel frame provides a screening surface of 1 520 cm² — 27% larger than the 400 mm model, making it suitable for applications requiring high sample throughput or analysis of larger aggregates. Two configurations are available: wire mesh (450.1) conforming to ISO 3310.1, ASTM E-11, and NF X11-504, covering 20 µm to 125 mm; and perforated plate with square and round holes (450.2) conforming to ISO 3310.2 and ASTM E-323. For fine mesh openings below 100 µm, reinforcement mesh placement is available as an option. Each sieve carries individual laser-engraved identification and is supplied with a certificate of attestation per 2.1 EN 10204.

Frequently Asked Questions (FAQs)
Q: What material is the frame made from?
A: The frame is manufactured from AISI-316 stainless steel with a mirror-polished finish. Like the 400 mm sieve range, the 450 mm sieve uses AISI-316 rather than the AISI-304 used on smaller frame sizes. AISI-316 provides enhanced corrosion resistance and is well suited to demanding laboratory and industrial environments.
Q: What is the screening surface area of this sieve?
A: The 450 mm × 100 mm sieve provides a screening surface area of 1,520 cm².
Q: What is this sieve size designed for?
A: The CISA 450 mm × 100 mm sieve is designed for particle size testing and coarse particle separation.
Q: What configurations are available for this sieve size?
A: Two configurations are available for the 450 mm × 100 mm frame:
• 450.1 — Wire mesh, conforming to ISO 3310.1, ASTM E-11, and AFNOR NF X11-504, with openings from 20 µm to 125 mm.
• 450.2 — Perforated plate, available in square-hole and round-hole versions, conforming to ISO 3310.2 and ASTM E-323, with openings from 4.00 mm to 125 mm.
Q: Is a reinforcement mesh available for fine openings in this frame size?
A: Yes. For mesh openings smaller than 100 µm, an optional reinforcement mesh is available to provide additional mechanical support within the large 450 mm frame. Contact Lasec when placing your order if this option is required.
Q: What is the full wire mesh range available in this frame size?
A: Configuration 450.1 is available with wire mesh openings from 20 µm to 125 mm. The complete mesh size table, including ISO 3310.1 openings, ASTM E-11-2013 designations, and CISA product codes, are available on the details section of the product page.
Q: Which standards does this sieve conform to?
A: Configuration 450.1 (wire mesh) conforms to ISO 3310.1, ASTM E-11, and AFNOR NF X11-504. Configuration 450.2 (perforated plate) conforms to ISO 3310.2 and ASTM E-323.
Q: What certificate is supplied with the sieve?
A: Every CISA 450 mm × 100 mm sieve is supplied with a certificate of attestation conforming to EN 10204 2.1.
Q: Is a calibration certificate available?
A: Yes. An optional calibration certificate with uncertainty value is available on request. Contact Lasec when placing your order to include this option.
Q: How is each sieve individually identified?
A: Each sieve carries an individual laser-engraved identification mark to support traceability and quality management requirements.
Q: What accessories are available for the 450 mm sieve?
A: The following optional accessories are available for the 450 mm × 100 mm sieve:
• Pan, 450 mm Ø stainless steel — Code 1900001
• Cover, 450 mm Ø stainless steel — Code 1900002
• Wet sieving pan and cover, 450 mm
• Cleaning ki
• Reinforcement mesh placement for openings smaller than 100 µm
• Calibration certificate with uncertainty value
Q: How can I order the wet sieving accessories or cleaning kit?
A: Contact Lasec for product codes, pricing, and ordering information for the wet sieving accessories and cleaning kit.
