Benchmark Agarose LE, 25 g

The A1700 is the Benchmark Agarose LE (Low EEO) in 25 g pack, the smallest pack-size of the standard molecular-biology-grade agarose family, sold at $67 for evaluation, low-throughput, or first-procurement workflows. LE (Low EEO) is the workhorse agarose grade for DNA electrophoresis at 0.5 % – 3 % gel concentrations, covering the fragment-size resolution range from large fragments (>10 kb) at low concentration to small fragments (~100 bp) at high concentration.

Author confidence note (MEDIUM): Brochure exists in corpus as image-only PDF (no text layer extractable). Specs sourced from universe label and standard LE-grade agarose conventions. Confirm exact gel-strength and EEO values with Benchmark Scientific technical support at first procurement.

Key Specifications

Why LE (Low EEO): Standard Molecular Biology Grade

Electroendosmosis (EEO) is the bulk flow of solvent through the agarose matrix during electrophoresis, high EEO causes band distortion, particularly for larger DNA fragments. LE (Low EEO) agarose is processed to minimize electroendosmotic flow, producing sharp, well-resolved bands across the standard DNA-electrophoresis fragment-size range.

Pick the LE grade (A1700 family) when:

• Workflow is standard DNA electrophoresis at 0.5 % – 3 % gel concentration
• PCR product checks, restriction-digest analysis, plasmid prep verification, DNA-size estimation
• Daily-throughput general-purpose electrophoresis where the standard LE grade covers the workflow
• Cost-optimized procurement vs specialty agaroses (HR, LM, 3:1)

Pick a specialty agarose when the workflow demands:

• A1801-HR (PCR-grade HR): high-resolution sequencing-prep / cloning-prep workflows
• A1801-LM (low-melt): recovery of intact DNA from gel slices for downstream cloning
• A1801-31 (3:1): high-resolution separation of small / mid-range fragments

Pack-Size Economics: A1700 / A1701 / A1705 LE Family

Pick the 25 g pack for first-time procurement, evaluation, or workflows running <10 standard gels per quarter. Step to the 100 g pack for routine institutional use; step to 500 g for high-throughput / shared-facility procurement at the lowest per-gram cost.

Application Profile

Standard DNA electrophoresis. The workhorse application. PCR product visualization, restriction-digest analysis, plasmid-prep verification, DNA-size estimation against ladder standards.

Educational laboratory teaching. Molecular biology coursework demonstrating DNA gel electrophoresis fundamentals; the small pack-size supports first-time-use student-cohort exercises at low procurement cost.

Method-development workflows. Protocol-development comparing gel concentration / running conditions across fragment-size ranges.

Multi-investigator shared lab procurement. Small-pack option for individual investigators in a facility that also stocks larger LE packs for high-throughput work.

Backup / bridge procurement. Small-pack option for labs running short on the 100 g or 500 g supply during reorder cycle.

Ordering & Configuration

Pair with electrophoresis chassis. Confirm horizontal gel electrophoresis chassis inventory at order. The agarose is workflow-incomplete without a chassis (Benchmark Scientific BR5000 / BV101 / BV1010 series).

Pair with running buffer. Confirm 1× TAE or 1× TBE running buffer inventory (or stocks of 50× TAE / 10× TBE concentrate per workflow).

Pair with DNA stain. Confirm GelGreen / GelRed / SYBR / EtBr stain inventory per facility safety policy.

Confirm at quote: workflow throughput sizing (pack-size selection), specialty-agarose pairing (HR / LM / 3:1) if needed, electrophoresis chassis pairing, and lead time.

Warranty: Per Benchmark Scientific standard reagent terms. Confirm at quote.

Benchmark Agarose LE family. Pick the right pack:

- A1700 (this product): 25 g ($67, $2.68/g), evaluation / low-throughput

- A1701 (100 g ($162, $1.62/g)) standard institutional

- A1705 (500 g ($563, $1.13/g)) high-throughput / facility procurement

Pick the 25 g pack for evaluation or first-time procurement; step to larger packs for ongoing high-throughput workflows; step to specialty agaroses (A1801 family) for high-resolution / low-melt / mid-range fragment workflows.
