Isopropyl Alcohol 70%

Good — pricing context confirmed. Here's your description:

Suggested Shopify title: 70% Isopropyl Alcohol — Sterile Technique Standard, 32oz

This is the most-used consumable in any mycology lab. It is on your gloves before you enter the SAB. It is on every jar exterior before it crosses the threshold into your work zone. It is the mist that pulls airborne particles down to the floor of your still air box before every session. You burn through it faster than anything else you own — which is exactly why it belongs in your store cart alongside everything else.

The 70% concentration is not a compromise — it is the scientifically established optimum. Pure 99% isopropyl alcohol actually kills microorganisms less effectively. The mechanism: alcohol disrupts microbial proteins through denaturation, and water is required as the carrier that facilitates penetration into cell walls. Pure IPA dehydrates the cell surface too quickly, potentially forming a protective protein layer before full penetration. The 70% solution penetrates more effectively and achieves complete microbial kill. This is the standard used in every professional mycology and microbiology lab worldwide.

How it gets used in every session:

• Wiping all surfaces before sterile work begins
• Spraying gloves before and during SAB use
• Misting the SAB interior to pull airborne particles to the floor
• Wiping jar and plate exteriors before they enter the SAB
• Disinfecting tools and work surfaces between sessions

One rule worth knowing: allow IPA to fully evaporate before any contact with open culture media. Residual alcohol on a surface can inhibit mycelial germination on agar plates. Spray, wait, then work.
