Efficient, leaf punch tools for quick, precise field sampling. For use with the 3CR Bio Leaf Sample Collection Kit.
BASIC LEAF CUTTING TOOL
The 3CR Bio Basic Leaf Cutting Tool is a lightweight, easy-to-use, low-cost punch designed for precise sampling of thin or soft materials, ideal for fieldwork. This tool is expertly designed to core, punch, and retrieve samples from thin or soft source materials such as leaves. The tool comprises a convenient, hollow plastic pen-style holder, mounted with a durable stainless steel cutting tip at one end. It features an internal push-button-operated plunger for safe and efficient sample disc ejection. The tool produces a precise ¼ inch diameter disc, making it ideal for detailed sampling tasks. For best results, clean the cutting tip between each sample extraction by coring blank filter paper or rinsing with water or ethanol. This low-cost leaf punch is lightweight, easy to use, and perfect for fieldwork.
ADVANCED LEAF CUTTING TOOL
The 3CR Bio Advanced Leaf Cutting Tool is designed to streamline and enhance your sampling process. This high-precision leaf tissue punch produces a single ¼ inch diameter disc effortlessly. It features a unique mechanism that securely holds a standard snap-top or screw-top 2 mL storage tube in a fixed position, allowing the sample to be received without any need for touching or manipulation. Ideal for fieldwork, this advanced leaf punch significantly reduces effort and time when performing multiple samplings, ensuring accuracy and efficiency in every use.

This product is based on silica Column purification. The sample is lysed and digested with lysate and protease, DNA is released into the lysate. Transfer to an adsorption column. Nucleic acid is adsorbed on the membrane, while proteinis not adsorbed and is removed with filtration. After washing proteins and other impurities, Nucleic acid was finally eluted with low-salt buffer (10mmTris, pH9.0, 0.5mm EDTA). This product carries 0.1-0.2mm acid glass beads, which can improve the wall-breaking effect of lysozyme resistant bacteria, the success rate and DNA yield through physical bead grinding.

Storage and Stability
Lysozyme and Proteinase K should be stored at 2-8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions.
This product provides fast and easy methods for purification of total DNA for reliable PCR and southern blotting. Total DNA can be purified from bacterial culture, body fluids, food and fermentation.
These kits are suitable for the isolation of total RNA from a range of samples including cells, bacteria, yeast, virus and bodily fluids including plasma/serum, blood, saliva, CSF and more. Extract high quality and purity RNA with excellent RIN values and A260/A280 suitable for downstream applications including qRT-PCR, RT-PCR, microarrays, NGS and more. These kits purify all sizes of RNA from large mRNA, lncRNA down to microRNA (miRNA) in the same fraction without the requirement of phenol. Isolate all RNA sequences at an equal rate irrespective of size. Moreover, when the RNA sequences are small (e.g. miRNA), the column binds small RNAs regardless of their GC content.
Total RNA Purification 96-Well Kit (High Throughput and High Throughput Deep Well)
This 96-well kit provides a rapid method for the high-throughput isolation and purification of total RNA in 30 minutes using vacuum manifold, plate centrifuge, or liquid handlers with vacuum capabilities. Total RNA can be isolated from a broad range of sample sources including cultured cells, tissues, blood, serum, plasma, bacteria, yeast, fungi, and viruses.
