Tabel Alat Dan Bahan Pencucian Pahat
No Nama Fungsi Gambar
1. Asam klorida pekat (acl)
Melarutkan banyak jenis logam
dan menghasilkan
logam klorida dan gas hidrogen.
Ia juga bereaksi dengan senyawa dasar semacam kalsium karbonat dan tembaga(ii) oksida, menghasilkan klorida terlarut yang dapat dianalisis.
2. Alkohol 96% Membersihkan permukaan
seperti laptop, meja, dll
3. Gelas ukur/gelas kimia
Gelas ukur adalah peralatan laboratorium umum yang digunakan untuk mengukur volume cairan serta wardah
4. Kuas Sebagai alat bantu membersihkan pahat
5. Sarung tanggan dan masker (apd)
Untuk melindungi saat melakukan penyucian
6. Kacamata Untuk melindungi mata dari carian
7. Pinset Untuk pemegang pahat
Selanjutnya langkah – langkah proses pencucian pahat sebagai berikut : 1. Gunakan peralatan kacamata,sarung tangan serta masker.
2. Tuangkan asam klorida pekat ke gelas ukur sebanyak 20-30 mm.
3. Masukan pahat yang akan dicuci kedalam gelas ukur tunggu kurang lebih 5 menit 4. Angkat pahat dari gelas ukur menggunakan pinset kemudian bersihkan
menggunakan kuas.
5. Masukan pahat ke dalam gelas ukur yang sudah di isi oleh alkohol sebanyak 20-30 mm.
6. Lalu bersihkan pahat potong di air mengalir menggunakan pinset .
7. Kemudian keringkan pahat serta simpan dan uji dengan Mikroskop Dino-Lite
