Lab Ware / 實驗室用品

Secondary schools need laboratory work because it provides students hands-on learning experience; reinforce understanding; develops practical skill; promotes scientific inquiries.

Overall, laboratory work in secondary school is essential for providing practical, hands-on experiences that enhance students' understanding of scientific concepts, develop important skills, and prepare them for future academic and professional pursuits in the sciences.

中學需要實驗室工作，因為它能為學生提供動手學習的經驗；加強理解；培養實踐技能；促進科學探究。

總之，中學的實驗室工作對於提供實用的實踐經驗至關重要，這些經驗可以增強學生對科學概念的理解，培養重要的技能，並為他們將來從事科學方面的學術和專業工作做好准備。

Borosilicate Glassware (3.3)

Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10−6 K−1 at 20 °C), making them more resistant to thermal shock than any other common glass. Such glass is subjected to less thermal stress and can withstand temperature differentials without fracturing of about 165 °C (300 °F).[1] It is commonly used for the construction of reagent bottles and flasks, as well as lighting, electronics, and cookware.Borosilicate glass is sold under various trade names, including Borosil, Duran, Pyrex, Glassco, Supertek, Suprax, Simax, Bellco, Marinex (Brazil), BSA 60, BSC 51 (by NIPRO), Heatex, Endural, Schott, Refmex, Kimax, Gemstone Well, United Scientific, and MG (India)

硼矽玻璃是一種以二氧化矽和三氧化二硼為主要玻璃形成成分的玻璃。硼矽玻璃的熱膨脹系數非常低（20 °C時≈3×10-6 K-1），因此比其他普通玻璃更能抵抗熱沖擊。這種玻璃受到的熱應力較小，可以承受約 165 °C（300 °F）的溫差而不破裂。它常用於制造試劑瓶和燒瓶，以及照明、電子產品和炊具。硼矽玻璃有多種商品名稱，包括 Borosil、Duran、Pyrex、Glassco、Supertek、Suprax、Simax、Bellco、Marinex（巴西）、BSA 60、BSC 51（由 NIPRO 生產）、Heatex、Endural、Schott、Refmex、Kimax、Gemstone Well、United Scientific 和 MG（印度）。

Plasticware / 實驗室塑料

Laboratory plasticware refers to laboratory equipment made of plastic materials. It includes a wide range of products such as test tubes, petri dishes, pipettes, containers, flasks, and funnels, with the advantages of lightweight, reusable, environment friendly, and can be autoclaved.

實驗室塑料器皿是指用塑料材料制成的實驗室設備。它包括試管、培養皿、移液管、容器、燒瓶和漏鬥等多種產品，具有重量輕、可重覆使用、環保、可高壓滅菌等優點。

Metalware / 金屬材質

Laboratory metalware is a general name used for all lab items or tools made of metal or metallic alloys that are not used as reagents but rather as tools or lab equipment. Some examples of laboratory metalware include laboratory burners, retort stands, rods, clamps, boss heads, ring clamps, wire gauge, burner stands, racks and more.

實驗室金屬器皿是所有由金屬或金屬合金制成的實驗室物品或工具的總稱，這些物品或工具不用作試劑，而是用作工具或實驗室設備。實驗室金屬器皿的一些例子包括實驗室燃燒器、蒸餾架、棒、夾具、凸頭、環形夾具、線規、燃燒器支架、架子等。

Paperware / 紙質材料

Laboratory paper products are used in various laboratory applications such as filtration and chromatography. Some examples of laboratory paper products include filter papers and chromatography paper. There are many manufacturers and suppliers of laboratory paper products such as Whatman, GE Healthcare and Hawach.

實驗室紙制品用於各種實驗室應用，如過濾和層析。實驗室用紙產品的一些例子包括濾紙和色譜紙。實驗室用紙產品有許多制造商和供應商，如Whatman、GE Healthcare 和 Hawach。

Rubberware / 橡膠

Laboratory rubber products such as bungs and tubing are used in various laboratory applications such as sealing containers or apparatuses and for fermentation in wineries. Rubber tubing and bungs are well received with their characteristics of chemical and thermal resistance, flexibility and elasticity, superb performance in vacuum and pressure application, which make them the best lightweight option to seal containers or apparatuses.

實驗室橡膠制品（如塞子和管子）可用於各種實驗室應用，如密封容器或設備以及釀酒廠的發酵。橡膠管和管座具有耐化學性和耐熱性、柔韌性和彈性、在真空和壓力應用中的卓越性能等特點，是密封容器或設備的最佳輕質選擇，因而廣受好評。
