Thank you, Tony, and good day, everyone. Today, we are reporting our financial results for the first quarter 2023, as well as updating our financial guidance for the year. Unless otherwise mentioned, all financial measures discussed reflect adjusted non-GAAP measures. As shown in our press release this morning, we delivered revenue of $182.7 million in the first quarter. The highlight continues to be the performance of our base business, which grew by 7% in constant currency, driven by the performance of our chromatography and proteins businesses, despite challenging market conditions. For the first quarter, our total revenue decreased by 12% as reported and 9% at constant currency. FX impact for the quarter was about $5 million, creating a three-point headwind on reported growth. Based on current conditions, we expect FX headwinds to continue through the first half of 2023 and then shift to tailwinds in the second half netting out to a zero impact for the full year. For our overall revenue performance, we saw year-over-year reduction in COVID revenue of $30 million. This was partially offset by performance on our base business, which grew by $10 million or 4% as reported and 7% at constant currency. As it relates to regional revenue growth, we saw strong performance in Asia, with Europe and North America down as expected due to COVID revenue declines. For the quarter, overall, revenues from Asia, rest of the world increased by 21%, while North America and Europe contracted by 15% and 21% respectively. While revenue growth in Asia was strong, orders in the region especially in China, dropped off significantly setting us up for tougher last three quarters in 2023 for this region. Regarding overall revenue distribution by region for the first quarter, Asia represented 23%, Europe represented 39%, and North America represented 38% of our global business. Now, moving down to our income statement. First quarter 2023 adjusted gross profit was $100.8 million, a reduction of $23.8 million or 19%, compared to the 2022 first quarter. Adjusted gross margin of 55.2% in the quarter goes down from 60.4% in the 2022 first quarter. Gross margins declines compared to the 2022 first quarter are related to volume deleverage, less favorable product mix tied to COVID revenue declines, material cost inflation and higher expenses tied to our capacity expansions. Sequentially, gross margins in the quarter improved by 370 basis points from our fourth quarter ‘22 performance of 51.5% driven by improved product mix benefiting our material costs, price increases covering material cost inflation from suppliers and operational cost optimization in our business. Now transitioning down the P&L to adjusted operating expenses. Adjusted research and development expenses for the first quarter 2023 were 6.7% of revenue. As Tony mentioned, we are focused on ramping up our R&D efforts here in 2023 in order to launch key new products into the market this year with our primary focus areas being filtration systems. Adjusted SG&A expenses for the first quarter 2023 were 26% of total revenue, compared to 22% in the same ‘22 period. Year-over-year percentage increases were tied to capacity expansion and investments in commercial resources to continue to drive growth and market share gains in the short and long-term. Now moving to adjusted earnings and EPS. First quarter 2023 operating income was $40.9 million, compared to $67.4 million in the prior year quarter and adjusted operating margin was 22.4%, compared to 32.6% in the same prior year period. Adjusted net income for the first quarter of 2023 was $36.3 million, compared to $53.7 million in the same quarter of 2022, a 32% reduction. Adjusted fully diluted EPS for the first quarter of 2023 was $0.64, compared to $0.92 in the same ‘22 period, a decline of $0.28 or 31%. Our cash, cash equivalents, short-term investments, which are GAAP metrics totaled $618 million at March 31st 2023. We will now transition to our 2023 full-year guidance. Our GAAP to non-GAAP reconciliations for our 2023 financial guidance are included in the reconciliation tables in today's earnings press release. As previously mentioned, unless otherwise noted, all 2023 financial guidance discussed will be non-GAAP. Please also keep in mind that our 2023 guidance may be impacted by fluctuations in foreign exchange rates, beyond our current projection of flat on full year sales and includes financial estimates for our FlexBiosys acquisition closed on April 17. Guidance does not include potential impact of any future acquisitions that the company may pursue. Based on our current view of market conditions, we are revising our 2023 full year revenue guidance, the GAAP metric to a range of $720 million to $760 million, a reduction of $40 million at the midpoint compared to our February guidance. This revised guidance reflects overall reported and constant currency growth of minus 10% to minus 5% and organic growth of minus 11% minus 6%. Our overall revenue guidance includes COVID revenues of $30 million to $40 million consistent with our February guidance and we have included $5 million of revenue from our FlexBiosys acquisition. We are updating our base business revenue guidance to a range of $685 million to $715 million, growing at 4% to 8% as reported and at constant currency. This compares to our February guidance of $730 million to $760 million growing at 11% to 15% as reported and 12% to 16% at constant currency. We are revising our 2023 adjusted gross margin guidance to the range of 52% to 53%, 50 basis point reduction from our previous guidance of 52.5% to 53.5%, driven primarily by lower revenue projections for the year. We are modifying our adjusted operating income guidance to a range of $153 million to $158 million for the $23.5 million at midpoint from our February guidance of $176 million to $182 million. Our adjusted operating margin guidance is now in the range 20.5% to 21.5% for the year compared with our February guidance range of 22.5% to 23.5% of revenue. Adjusted other income guidance is being increased to $14 million, compared to prior guidance of $10 million. And we continue to expect 2023 adjusted income tax expense to be approximately 20% of adjusted pre-tax income. We're revising our adjusted net income guidance to the range of $134 million to $138 million, a difference of $15.5 million at the midpoint from our February guidance of $149 million to $154 million. We are revising our adjusted EPS guidance to the range of $2.35 to $2.42 per fully diluted share, a reduction of $0.27 from our previous guidance of $2.61 cents to $2.69. Our adjusted EPS guidance assumes 57.1 million weighted average fully diluted shares outstanding at year-end 2023. Adjusted EBITDA is now expected to be in the range of $190 million to $194 million, a reduction of $24 million at the midpoint from our prior guidance of $213 million to $219 million with depreciation and intangible amortization expense is expected to be approximately $35.7 million, and $30.2 million respectively. Adjusted EBITDA margins continue to be strong and are expected to be in the range of 25.5% to 26.5% for the year reflective of the exclusion of fixed depreciation cost from our capacity expansions from this metrics. We expect year-end cash and cash equivalents, a GAAP metric to be in the range of $620 million to $640 million with $60 million of CapEx investments being fully funded by cash generation from our operations. This provides any cash figures inclusive of cash payments made for our April acquisition of FlexBiosys. This completes our financial report and guidance update. And I will now turn the call back to the operator to open the lines for questions.
