Real-World Testing: Putting VWR Testing Sieves, All Stainless Steel 7SS8F Full Height to the Test
First Use Experience
I first put the VWR Testing Sieves, All Stainless Steel 7SS8F Full Height to use in my lab, analyzing soil samples collected from various construction sites. The sieve was part of a stack used to determine the particle size distribution of the soil, which is crucial for determining soil suitability for construction purposes. The initial testing was performed in a relatively controlled indoor environment, although dust levels were naturally elevated due to the nature of the samples.
The sieve performed admirably under these conditions, allowing for quick and efficient separation of soil particles. It’s robust construction meant it withstood the vibration of the mechanical shaker without any deformation or damage. The uniform mesh size ensured consistent and accurate separation of particles based on their size.
The ease of use was immediately apparent. The full height of the frame provided ample space for the sample, reducing the risk of spillage. The sieve’s robust design also meant that it was easy to handle and manipulate, even when wearing gloves. After first-time use, I did notice a slight static cling of fine particles to the stainless steel mesh, but this was easily remedied with a soft brush.
Extended Use & Reliability
After several months of use, the VWR Testing Sieves, All Stainless Steel 7SS8F Full Height has proven to be a reliable and durable tool. The stainless-steel construction has held up well, showing no signs of rust or corrosion, despite repeated exposure to moisture and abrasive soil particles. The mesh has maintained its integrity, with no noticeable stretching or distortion.
The sieve is easy to clean and maintain. I simply rinse it with water and use a soft brush to remove any remaining particles. Occasionally, I use a mild detergent to remove stubborn stains or residue. It is important to dry the sieve thoroughly after cleaning to prevent water spots and maintain its pristine condition.
Compared to my previous experiences with brass sieves, the VWR Testing Sieves, All Stainless Steel 7SS8F Full Height have been a significant upgrade. The stainless steel construction offers superior durability and corrosion resistance. The certified accuracy and compliance provide greater confidence in the reliability of test results. The larger sample capacity of the full-height frame improves efficiency.
