The IPD1196-CM is the EVA (ethylene-vinyl acetate) cap mat for sealing 96-well deep-well plates during the BeadBlaster 96 ball-mill cycle — DNase / RNase free for nucleic-acid extraction workflows. Workflow-mandatory accessory paired with the IPD1196-40 (96-well prefilled bead plate) and IPD1196-MP (96 deep-well 2.0 mL genomics plate) for the BeadBlaster 96 high-throughput tissue homogenization workflow.

Why an EVA Cap Mat — Bead-Mill Plate Sealing
The BeadBlaster 96 ball-mill cycle subjects 96-well plates to vigorous arced motion at speeds up to 1800 rpm during homogenization — without proper sealing, samples would splash / cross-contaminate / escape the wells.
EVA cap mat workflow:
- Prefilled bead plate (IPD1196-40) is loaded with samples
- EVA cap mat (this product) is pressed onto the plate — elastomer creates tight seal across all 96 wells
- Sealed plate is loaded into BeadBlaster 96 chassis and homogenized
- Cap mat is removed for sample recovery (cap mat is single-use disposable for nucleic-acid workflows; multi-use for non-contamination-critical workflows per institutional protocol)
EVA elastomer advantages:
- Tight well sealing under bead-mill stress without cap detachment
- Chemical compatibility with typical lysis buffers (Tris, EDTA, SDS, guanidine salts) used in nucleic-acid extraction
- Repenetration ability — elastomer can be pierced for sample recovery without compromising remaining wells (workflow-flexible)
- Per-cap-mat cost economy — at $102 per cap mat (covers 96 wells), per-well sealing cost is $1.06
DNase / RNase Free Specification
The DNase / RNase free certification is critical for nucleic-acid extraction workflows — contaminating nucleases would degrade target nucleic acid before / during the homogenization step, compromising downstream extraction yield and integrity.
Workflows requiring DNase/RNase-free:
- DNA extraction from tissue samples
- RNA extraction (especially RNase-sensitive — supports RNA-Seq library prep, RT-qPCR, microarray workflows)
- microRNA / small-RNA extraction
- NGS library construction starting from tissue
For non-nucleic-acid workflows (e.g., protein extraction, metabolomics), the DNase/RNase-free spec is over-engineered but doesn't compromise workflow.
Application Profile
High-throughput tissue homogenization with downstream nucleic-acid extraction — the workhorse application. 96-well tissue homogenization for DNA / RNA / miRNA extraction.
RNA-Seq library prep starting material — sample-prep workflow feeding NGS library construction.
RT-qPCR sample-prep workflows — tissue homogenization with downstream RT-qPCR quantification.
Multi-investigator shared bench at 96-well bead-mill workflows — facilities benefit from per-cap-mat consumable economics.
Method-development workflows — protocol-development workflows where DNase/RNase-free standardization is part of method validation.
Replacement procurement — labs replenishing cap-mat inventory per workflow throughput.
Pack-Quantity Sizing
The IPD1196-CM ships per-cap-mat (each cap mat seals one 96-well plate). For workflows running multiple plates per day, plan procurement to match expected throughput — typical production-scale sample-prep facilities consume 5-20 cap mats per week.
Ordering & Configuration
Pair with chassis + plate inventory. Confirm IPD9600 BeadBlaster 96 chassis + IPD1196-40 (or IPD1196-MP) plate inventory at order.
Single-use disposable for nucleic-acid workflows. EVA cap mats are single-use for DNase/RNase-critical workflows; institutional protocol may permit multi-use for non-nucleic-acid workflows.
Storage. Cap mats ship in sealed packaging; store at room temperature.
Confirm at quote: chassis pairing (IPD9600 in inventory), plate format (IPD1196-40 / IPD1196-MP), workflow throughput (per-week / per-month plate count), and lead time.
