We will launch the following products in January 2026. ● Standard products for environmental analysis (2 items) From Wellington Laboratories, we will sell the PFAC-MXE, a 22-component mixed standard solution that adds HFPO-DA* (GenX) to PFAC-MXC (49880-85), and the MPFAC-MXE, a 14-component internal mixed standard solution that adds M3HFPO-DA (Mass-Labelled GenX) to MPFAC-C-ES (49880-83). ● Standard products for environmental and food analysis (13 items) The new products added this time are 13 standard items for compounds with updated or changed residue standards. ● High-performance alkyne DACN (2 items) The new products added this time are designed to enhance water solubility while maintaining reactivity for easier use in mid-sized pharmaceuticals. ● Chromagar medium 500 g packaging (3 items) Chromagar has decided to change the capacity of the products. As a result, we will discontinue some of the current packaging and introduce a new 500 g packaging. While there will be changes in capacity, packaging containers, and labels, there will be no changes to the contents.

We will launch the following products in December 2025. ● Standard Products for Environmental Analysis (2 items) Wellington Laboratories offers a wide range of mixed standard solutions and standard products for PFAS precursors and related substances that correspond to various PFAS analytical methods. We will begin selling mixed standard solutions for 10 types of PFAS and internal mixed standard solutions in response to the revision of the Water Supply Act ministerial ordinance in April 2026. ● Food Allergen Testing Kits (2 items) The Prima Ham food allergen testing kit, allergen wipe test kit series "Cashew Nuts," allows for the detection of allergenic proteins by adding extract components to the wipe solution, which dissolves the allergenic proteins and enables high-sensitivity detection of cashew nut components in the wipe solution. The reaction time is 20 minutes, and the detection sensitivity is 0.2 µg/mL (ppm) (total protein of the target food allergen in the test sample).

We will launch the following products in November 2025. ● Titration solution for quantitative analysis (1 item) We will sell a 20 L package of 0.1 mol/L hydrochloric acid (N/10). ● Kyowa Medical Instruments Co., Ltd. Adjusted liquid medium series (6 items) The use of Durham tubes, which easily float with small amounts of gas, makes it easy to determine results. Additionally, the test tube caps can be opened and closed with one hand, reducing the burden of work. Furthermore, by adding a new 100-pack option, you can now choose according to the amount of testing required. ● Sicagenius® ESBL gene type real-time PCR detection kit (1 item) ESBL is an enzyme that breaks down a wide range of β-lactam antibiotics, including penicillins, first to third generation cephalosporins, and monobactams. This kit simultaneously detects 22 types of 4-plex real-time PCR for 8 representative ESBL gene types (CTX-M-1 group, CTX-M-9 group, CTX-M-2 group, CTX-M-8 group, CTX-M-25 group, TEM, SHV, ESBL type GES) and an internal control (IC) to check for PCR inhibition.

We are conducting a campaign targeting NMR heavy solvents, NMR sample tubes, and spherical silica gel. We are offering these products at special prices, so we kindly ask you to consider purchasing our products during this opportunity. ■Campaign Period From November 4, 2025, to January 30, 2026 ■Campaign Target Products NMR heavy solvents (while supplies last) NMR sample tubes Spherical silica gel For more details, please download the campaign flyer or feel free to contact us.

We will launch the following products in October 2025. ● General-purpose reagents (5 items) We are reviewing the packaging capacities and consolidating general-purpose reagents of special grade, deer special grade, and deer grade 1 specifications. We will sell new capacities of specifications that are not targeted for consolidation as alternatives to discontinued items. ● Standard materials for environmental analysis (3 items) We will begin handling three standard materials manufactured by LGC Standards for compounds listed in the positive list. ● Shikajenius MRSA-related gene real-time PCR detection kit (1 item) This kit detects MRSA-related genes using a 4-plex real-time PCR. ● Rapid screening reagent for third-generation cephalosporin-resistant bacteria (1 item) This reagent is used to screen Enterobacteriaceae that show resistance to third-generation cephalosporin antibiotics. ● Standard bacterial strains for MALDI TOF-MS quality control (3 items) This product is a set of standard bacterial strains that can be used for quality control of the Bruker MALDI Biotyper. We have prepared sets tailored to specific fields.
