Parts and money零件和钱

What it costs, as far as we've read要花多少钱：目前查到的部分

Prices are in pounds including VAT, read between 2026-10-09 and 2026-10-11. Listed means read on a supplier page on the date the full list gives for that line. A line whose price hasn't been read from a source yet shows "—" and stays out of every total, so each total is a floor ("≥"): the sum of the listed lines only, with how many lines it covers. Shipping and labour are left out.

价格单位为英镑、含增值税，读取于 2026-10-09 至 2026-10-11 之间。标价指在完整清单为该条目注明的日期、从供应商页面上读到的价格。还没从任何来源查到价格的条目显示“—”，不计入任何总数，所以每个总数都只是下限（“≥”）：只把有标价的条目加起来，并写明覆盖了几条。运费和人工都不算在内。

Honest reading: we don't know yet whether SWELL is cheap. The design's cost targets are ≤ £500 for the core and ≤ £650 for the build, with a £1,000 ceiling, but most lines have no price read from a source, so no total is compared with them, or with any other instrument, until every line is priced. Pricing the rest, starting with the filter set, the tube lens and the power and pump electronics, is the next job on this list. The levers named but never pulled: a coloured-glass emission filter with one cheap dichroic, a generic tube lens, a generic 20X objective for the 10× track, and a lab print service that charges only for the filament.

老实说：SWELL 到底便不便宜，我们还不知道。设计的成本目标是核心 ≤ £500、整机 ≤ £650、上限 £1,000，但大多数条目还没从任何来源查到价格，所以在每一条都有价格之前，任何总数都不拿来和目标比，也不和别的仪器比。接下来要做的，就是把剩下的条目查出价格，先查滤光片组、筒镜和电源、水泵电子件。点过名、但从没用上的省钱办法：用有色玻璃发射滤光片配一片便宜的二向色镜、通用筒镜、10× 路线改用通用 20X 物镜，以及只收材料费的实验室打印服务。

The main parts only. In the price column, "—" means the price is not yet read; in the part-number column, that the list gives no part number for that line. The full list, all 45 lines with each one's price basis, supplier, part number and safety rating, is swell-bom-2026-10-11.csv (a CSV file: pm/BOM.csv from the download, after three lines saying what it is, who wrote it and its licence). H-01's optics module is not a stock OpenFlexure part: OpenFlexure's v7 high-resolution module takes a 50 mm tube lens (Thorlabs AC127-050-A, per its build pages, read 10 October 2026), and they list no version for SWELL's 100 mm lens, so a modified module would have to be drawn; none has been. Euro and dollar prices were converted at assumed rates (EUR 0.86, USD 0.75).

这里只列主要零件。价格一栏的“—”表示尚未查价；零件编号一栏的“—”表示清单里这一条没有写零件编号。完整清单共 45 条，含每条的定价依据、供应商、零件编号和安全等级，见 swell-bom-2026-10-11.csv（CSV 文件：下载包里的 pm/BOM.csv，前面加了三行，说明它是什么、谁写的、用什么许可）。H-01 的光学模块不是 OpenFlexure 的标准件：OpenFlexure v7 的高分辨率模块用 50 mm 筒镜（Thorlabs AC127-050-A，见其组装说明，2026 年 10 月 10 日读取），说明里没有适配 SWELL 所用 100 mm 筒镜的版本，所以得另画一个改过的模块；目前还没画。欧元和美元价格按假设汇率换算（EUR 0.86, USD 0.75）。

Where the chemistry happens化学部分在哪做

Finding a suitable lab, anywhere在任何地方找合适的实验室

The gel chemistry belongs only in an equipped, supervised laboratory that works under its own safety rules. We name no labs here: this is the list of what to ask one for. Nobody has been contacted about SWELL.

凝胶化学只能在设备齐全、有人监督、按自身安全规程运作的实验室里做。这里不点名任何实验室，只列出该向实验室确认的事项。关于 SWELL，我们没有联系过任何人。

1. A fume hood, or local exhaust ventilation, for weighing powders and for the formaldehyde and monomer steps.有通风橱或局部排风，用来称粉末、做甲醛和单体相关步骤。
2. Written permission for these reagents: acrylamide, bis-acrylamide and formaldehyde (CMR substances), APS, TEMED, sodium acrylate, imidazole, an SDS buffer at 95 °C and NHS-ester dyes in DMSO.书面同意使用这些试剂：丙烯酰胺、双丙烯酰胺和甲醛（CMR 物质），过硫酸铵、TEMED、丙烯酸钠、咪唑、95 °C 的 SDS 缓冲液，以及溶在 DMSO 里的 NHS 酯染料。
3. A hazardous-waste route for liquids and polymerised gels, and what it costs.液体废物和聚合后凝胶的危废处理渠道，以及费用。
4. An ordering route: the lab orders the CMR reagents, because suppliers may not sell them to private individuals. Never present yourself as a business if you are not one.采购渠道：由实验室订购 CMR 试剂，因为供应商可能不卖给个人。不是公司就绝不要冒充公司。
5. Lockable chemical storage, and fridge and freezer space for reagents and gels.可上锁的化学品柜，以及存放试剂和凝胶的冷藏、冷冻空间。
6. Basic equipment: pipettes, a mini-centrifuge, a heat block reaching 95 °C, an incubator, a balance and a pH meter.基本设备：移液器、迷你离心机、能到 95 °C 的加热块、培养箱、天平、pH 计。
7. Bench space for a small low-voltage microscope for a few months, under the lab's own induction, risk assessments and lone-working rules.能放一台小型低压显微镜几个月的台面，并遵守该实验室自己的入门培训、风险评估和单人作业规定。
8. Then choose: among the labs that confirm the first four points, the cheapest that can start when you need it.最后挑选：在前四条都确认没问题的实验室里，选能按你的时间开始、费用最低的一家。
