What Happened When I Tried the BrandTech Pipettor Tips Bulk 5ML PK200 702595 Pipettor Tips Bulk 5ML PK200, Pack of 200
Pipetting, for those unfamiliar, is a core skill in any laboratory setting, from research to diagnostics. The BrandTech Pipettor Tips Bulk 5ML PK200 702595 Pipettor Tips Bulk 5ML PK200, Pack of 200 represent a workhorse solution for reliably and accurately transferring liquids. BrandTech is a known and respected name in lab equipment, and these tips, coming in a bulk pack of 200, promise both value and consistent performance. I’ve spent over a decade in various labs, so I have a pretty good idea of what makes a good pipettor tip – and what doesn’t.
My previous lab’s supplier started having significant backorders on our usual 5mL tips, and our research was grinding to a halt, so finding a dependable alternative quickly became critical. We needed a readily available, reliable, and cost-effective solution. I was tasked with finding a substitute. After reviewing several options, the BrandTech Pipettor Tips Bulk 5ML PK200 702595 Pipettor Tips Bulk 5ML PK200, Pack of 200 seemed to offer the best balance of quality and value.
The tips arrived in a simple, no-frills package – a bulk bag, as advertised. Initial inspection revealed clean, colorless tips, consistent in shape and size. The material felt sturdy, not flimsy like some of the cheaper alternatives I’ve encountered. Compared to the Eppendorf and Gilson tips we typically used, these felt comparable in terms of material quality, although the packaging was definitely less refined.
My initial excitement stemmed from the promise of uninterrupted research. I was relieved to have found a potential solution to our tip shortage. However, past experiences with generic lab supplies have taught me to temper enthusiasm with cautious optimism.
Real-World Testing: Putting BrandTech Pipettor Tips Bulk 5ML PK200 702595 Pipettor Tips Bulk 5ML PK200, Pack of 200 to the Test
First Use Experience
I immediately put the BrandTech Pipettor Tips to use in a cell culture experiment that required precise dispensing of media and reagents. The tips readily fit our BrandTech Transferpette and, thankfully, also snugly accommodated our Finnpipette, as advertised in the product description. This compatibility was crucial, saving us the hassle of potentially needing to recalibrate multiple pipettors. The dispensing action was smooth and consistent, with no noticeable dripping or air leaks.
We tested the tips under various conditions. This included dispensing viscous solutions, such as glycerol, and volatile solvents, like ethanol. Performance remained consistent. Even when handling the ethanol, there was no noticeable degradation of the tip material, which is a definite plus. One minor issue arose when dispensing highly concentrated protein solutions; a few tips exhibited slight “hang-up,” where a small amount of liquid clung to the inner wall.
Extended Use & Reliability
After several weeks of daily use, the BrandTech Pipettor Tips have proven to be remarkably reliable. We haven’t encountered any significant batch-to-batch variations in quality, which can be a common problem with bulk-packaged lab supplies. The tips exhibit minimal wear and tear, even after repeated autoclaving (something we do to sterilize them for certain applications).
Cleaning is straightforward. A simple rinse with distilled water and ethanol, followed by air-drying, is usually sufficient. Compared to the more expensive, individually wrapped tips, these obviously require more care to maintain sterility. However, the cost savings more than compensate for the extra effort in our application. I would rate them as on par, if not slightly better, than some of the other generic tips we’ve used in the past in terms of overall durability and ease of maintenance.
