We have been well prepared to absorb this challenge by improving stock levels, investing in automation and tooling, and increasing production staff levels. We continue to manufacture 24 hours a day, 7 days a week and have increased our production capacity by an estimated 60% over the past 6 months. Additionally, we are continuing to make investments in molds, automation, and tooling to further increase our capacity in 2021. And we have implemented local business continuity plans to minimize potential operational impacts to our customers.
Raw materials, such as polymers, filters, and pipettes parts, are sourced primarily from suppliers in North America, where our manufacturing facility is located. We are also continuously working with our suppliers to discuss current supplies and delivery expectations. While we are working to build safety stock levels, global demand for some products is increasing, and this is resulting in increased lead times. We continue to work closely with our suppliers, and thank you for your patience.
