Extended Use & Reliability
After several weeks of rigorous testing involving various sample types, the Whatman Grade 707 Blotting Pad 28298-010, Pack of 50 continued to impress. The pads showed remarkable consistency in performance, regardless of the sample matrix. I consistently obtained clean and reproducible results.
The pads have displayed no signs of degradation or wear and tear. I have stored them properly in their original packaging. The pads are incredibly resilient and maintain their structural integrity even with repeated handling.
Maintenance is virtually nonexistent, as these are single-use pads. Their pre-cleaned nature negates the need for any pre-treatment or cleaning protocols. Compared to using standard filter paper, the Whatman Grade 707 Blotting Pad 28298-010, Pack of 50 significantly outperformed in terms of background noise and ease of use.
Breaking Down the Features of Whatman Grade 707 Blotting Pad 28298-010, Pack of 50
Specifications
The Whatman Grade 707 Blotting Pad 28298-010, Pack of 50 boasts several critical specifications. Each pad measures 10 x 14 cm. This offers ample surface area for various blotting applications.
The pads weigh 703 g/m2, indicating a substantial density that contributes to excellent absorption capacity. With a thickness of 2.60 mm, these pads provide a resilient and reliable support matrix. This thickness is crucial for maintaining structural integrity during blotting.
The Hertzberg flow rate is 120 sec./100 mL at a 10 cm head of water. This signifies the pad’s controlled absorption rate, preventing over-saturation or uneven distribution. The Klemm wicking rate test shows 96 sec./7.5 cm rise, illustrating the pad’s efficient capillary action for even liquid transfer.
These specifications matter because they ensure consistent and reliable performance in protein isolation. The controlled flow and wicking rates minimize artifacts and enhance the clarity of results. The uniform thickness and density guarantee even protein binding.
